the k.sub.tx and k.sub.ty that are solutions of the above equations
have a relationship of k.sub.tx>k.sub.ty, and the k.sub.b1x,

equations have a relationship of at least one of
k.sub.b1x<k.sub.b1y and k.sub.b2x<k.sub.b2y.
[0036] In the above equations, F.sub.x represents a load (N)
applied in the boundary line perpendicular direction D2 to a part
in which the first fabric 10 and the second fabric 20 are laminated
to the belt-shaped member 30 (hereinafter, also referred to as
"laminated part 61"), L.sub.x represents a displacement (mm) when a
load is applied to the laminated part 61 in the boundary line
perpendicular direction D2, F.sub.y represents a load (N) applied
to the laminated part 61 in the boundary line parallel direction
D1, L.sub.y represents a displacement (mm) when a load is applied
to the laminated part 61 in the boundary line parallel direction
D1, F.sub.b1x represents a load (N) applied to the first fabric 10
in the boundary line perpendicular direction D2, L.sub.b1x
represents a displacement (mm) when a load is applied to the first
fabric 10 in the boundary line perpendicular direction D2,
F.sub.b2x represents a load (N) applied to the second fabric 20 in
the boundary line perpendicular direction D2, L.sub.b2x represents
a displacement (mm) when a load is applied to the second fabric 20
in the boundary line perpendicular direction D2, F.sub.b1y
represents a load (N) applied to the first fabric 10 in the
boundary line parallel direction D1, L.sub.b1y represents a
displacement (mm) when a load is applied to the first fabric 10 in
the boundary line parallel direction D1, F.sub.b2y represents a
load (N) applied to the second fabric 20 in the boundary line
parallel direction D1, and L.sub.b2y represents a displacement (mm)
when a load is applied to the second fabric 20 in the boundary line
parallel direction D1, respectively.
[0037] The F.sub.x, F.sub.y, F.sub.b1x, F.sub.b2x, F.sub.b1y, and
F.sub.b2y are preferably the loads up to the maximum elongation in
a load-elongation curve drawn with the load on the vertical axis
and the elongation on the horizontal axis, which is a relationship
between the load applied to the laminated part 61, the first fabric
10, and the second fabric 20 in each of the boundary line
perpendicular direction D12 and the boundary line parallel
direction D1 and the elongation of the laminated part 61, the first
fabric 10, and the second fabric 20 when each of the loads is
applied. By setting the values of the F.sub.x, F.sub.y, F.sub.b1x,
F.sub.b2x, F.sub.b1y, and F.sub.b2y in this way, each of the values
of k.sub.tx, k.sub.ty, k.sub.b1x, k.sub.b1y, k.sub.b2x, and
k.sub.b2y can be calculated accurately.
[0038] The F.sub.x, F.sub.y, F.sub.b1x, F.sub.b2x, F.sub.b1y, and
F.sub.b2y are preferably the loads in a region of initial
deformation in which a load and a displacement are proportional to
each other in a load-elongation curve drawn with the load on the
vertical axis and the elongation on the horizontal axis, which is a
relationship between the load applied to the laminated part 61, the
first fabric 10, and the second fabric 20 in each of the boundary
line perpendicular direction 1D2 and the boundary line parallel
direction D1 and the elongation of the laminated part 61, the first
fabric 10, and the second fabric 20 when each of the loads is
applied. That is, the F.sub.x, F.sub.y, F.sub.b1x, F.sub.b2x,
F.sub.b1y, and F.sub.b2y are preferably the values in a region of
initial deformation in which a load and a displacement are
proportional to each other in each sample. By setting the values of
the F.sub.x, F.sub.y, F.sub.b1x, F.sub.b2x, F.sub.b1y, and
F.sub.b2y in this way, the k.sub.tx, k.sub.ty, k.sub.b1x,
k.sub.b1y, k.sub.b2x, and k.sub.b2y can be compared more
precisely.
[0039] The F.sub.x, F.sub.y, F.sub.b1x, F.sub.b2x, F.sub.b1y, and
F.sub.b2y may be the same values as each other. That is, the
L.sub.x, L.sub.y, L.sub.b1x, L.sub.b2x, L.sub.b1y, and L.sub.b2y
may be respective displacements when the same load is applied to
the laminated part 61, the first fabric 10, and the second fabric
20 in each of the boundary line perpendicular direction D2 and the
boundary line parallel direction D1. When the sizes of respective
samples of the laminated part 61, the first fabric 10, and the
second fabric 20 are the same as each other and the values of the
F.sub.x, F.sub.y, F.sub.b1x, F.sub.b2x, F.sub.b1y, and F.sub.b2y
are the same values as each other, the displacement can be measured
without changing the setting, conditions, or the like of a testing
machine according to each sample, so that the measurement of each
displacement becomes easy.
[0040] The garment 1 includes the first fabric 10, the second
fabric 20, and the belt-shaped member 30. FIG. 3 shows a plan view
of the first fabric 10, FIG. 4 shows a plan view of the second
fabric 20, and FIG. 5 shows a development view of the garment 1 as
viewed from the wearer side. In this regard, the expression
"development view of the garment 1 as viewed from the wearer side"
is referred to as a development view on the skin surface side of
the garment 1. As shown in FIGS. 3 and 5, the first fabric 10 is in
the back panel 3. As shown in FIGS. 4 and 5, the second fabric 20
is in the front panel 2. The second fabric 20 may include a second
fabric 20a on the right side in a right front panel, and a second
fabric 20b on the left side in a left front panel.
[0041] As the kind of the first fabric 10, for example, a woven
fabric of a plain weave, a twill weave, a satin weave, or the like;
a knit fabric of plain knitting, rib knitting, garter knitting, or
the like; a nonwoven fabric; or the like can be mentioned. Among
them, the first fabric 10 is preferably a knit fabric, and more
preferably a knit fabric of rib knitting. By constituting the first
fabric 10 in this way, the stretchability of the first fabric 10
can be enhanced.
[0042] The first fabric 10 may have multiple knit structures or
weave structures. As a specific example, a constitution in which
different kinds of knit structures such as rib knitting and mesh
knitting are included in the first fabric 10, or the like can be
mentioned. By including multiple knit structures or weave
structures in the first fabric 10, the characteristics can be
changed by a part of the first fabric 10. For example, the whole
knit structure of the first fabric 10 is formed by rib knitting, so
that the whole stretchability of the first fabric 10 is enhanced,
and the first fabric 10 is fitted to the body of the wearer. The
knit structure in the vicinity of the side of the first fabric 10
is formed by mesh knitting, so that the air-permeability in the
vicinity of the side in which heat is easy to be accumulated is
enhanced, and the wear comfort of the garment 1 can be
improved.
[0043] Examples of the material for the fiber constituting the
first fabric 10 include a synthetic fiber such as polyester,
polyurethane, and nylon; and a natural fiber such as cotton and
hemp. Among them, the material for the fiber constituting the first
fabric 10 is preferably a synthetic fiber, and more preferably
polyester. By constituting the first fabric 10 in this way, the
joining strength with the belt-shaped member 30 can be enhanced,
and the garment 1 is easily produced.
[0044] The thickness of the first fabric 10 is preferably 0.5 mm or
more, more preferably 0.7 mm or more, furthermore preferably 1 mm
or more, and particularly preferably 1.2 mm or more. By setting the
lower limit value of the thickness of the first fabric 10 in this
way, the joining strength with the belt-shaped member 30 is
enhanced, and the strength of a joining part 60 can be enhanced.
The upper limit value of the thickness of the first fabric 10 is
not particularly limited, and can be set to be, for example, 10 mm
or less, 5 mm or less, or 3 mm or less. In this regard, the
thickness of the first fabric 10 is obtained by measuring the
thicknesses in arbitrary multiple parts of the first fabric 10, and
then by averaging the obtained multiple values of the
thickness.
[0045] As the kind of the second fabric 20, a woven fabric, a knit
fabric, a nonwoven fabric, or the like can be mentioned, as in the
case of the kind of the first fabric 10, and among them, the second
fabric 20 is preferably a knit fabric, and more preferably a knit
fabric of rib knitting. By constituting the second fabric 20 in
this way, the second fabric 20 having the favorable stretchability
can be obtained. In addition, the second fabric 20 may have
multiple knit structures or weave structures, as in the case of the
first fabric 10.
[0046] Examples of the material for the fiber constituting the
second fabric 20 include a synthetic fiber and a natural fiber as
in the case of the material for the fiber constituting the first
fabric 10, and among them, the material is preferably a synthetic
fiber, and preferably polyester. By constituting the second fabric
20 in this way, the joining strength between the second fabric 20
and the belt-shaped member 30 is enhanced, and the second fabric 20
and the belt-shaped member 30 is easily joined.
[0047] The thickness of the second fabric 20 is, as in the case of
the thickness of the first fabric 10, preferably 0.5 mm or more,
more preferably 0.7 mm or more, furthermore preferably 1 mm or
more, and particularly preferably 1.2 mm or more. By setting the
lower limit value of the thickness of the second fabric 20 in this
way, the joining strength between the second fabric 20 and the
belt-shaped member 30 can be enhanced, and the strength of the
joining part 60 can be increased. The upper limit value of the
thickness of the second fabric 20 is not also particularly limited,
as in the case of the first fabric 10, and can be set to be, for
example, 10 mm or less, 5 mm or less, or 3 mm or less. In this
regard, the thickness of the second fabric 20 is obtained by
measuring the thicknesses in arbitrary multiple parts of the second
fabric 20, and then by averaging the obtained multiple values of
the thickness.
[0048] The first fabric 10 and the second fabric 20 may be fabrics
of different kinds or materials, but are preferably fabrics of the
same kind or material. By using the same kind or material for the
first fabric 10 and the second fabric 20, the physical properties
of the first fabric 10 and the second fabric 20 are equalized, and
a joining step of the first fabric 10 and the second fabric 20 is
easily performed. In addition, the first fabric 10 and the second
fabric 20 are preferably knit fabrics of synthetic fiber, and more
preferably rib knitting of polyester. By constituting the first
fabric 10 and the second fabric 20 in this way, the garment 1 that
is excellent in the stretchability and has the joining part 60 with
high strength can be obtained.
[0049] As the kind of the belt-shaped member 30, a woven fabric of
a plain weave, a twill weave, a satin weave, or the like; a knit
fabric of plain knitting, rib knitting, garter knitting, or the
like; a nonwoven fabric; or a material obtained by coating these
fabrics with a synthetic resin can be mentioned. Among them, the
kind of the belt-shaped member 30 is preferably a knit fabric. By
forming the belt-shaped member 30 with a knitted fabric, the
stretchability can be imparted to the belt-shaped member 30, and
the stretchability can also be imparted to the joining part 60. In
addition, because the belt-shaped member 30 has favorable skin
touch, the garment 1 that is comfortable to the wearer can be
obtained.
[0050] Examples of the material for the fiber constituting the
belt-shaped member 30 include a synthetic fiber such as polyester,
polyurethane, and nylon; and a natural fiber such as cotton and
hemp. Among them, the material for the fiber constituting the
belt-shaped member 30 is preferably a synthetic fiber, and more
preferably polyurethane. By constituting the belt-shaped member 30
in this way, the joining strength with the first fabric 10 and the
second fabric 20 is increased, and the productivity of the garment
1 can be enhanced. In addition, the stretchability of the
belt-shaped member 30 can also be enhanced.
[0051] As shown in FIG. 5, the belt-shaped member 30 is arranged
along the first fabric 10 and the second fabric 20. That is, the
belt-shaped member 30 is joined to both of the first fabric 10 and
the second fabric 20, and the first fabric 10 and the second fabric
20 are joined to each other with the belt-shaped member 30. By
joining the first fabric 10 and the second fabric 20 with the
belt-shaped member 30, as compared with a garment sewn with a
thread and a needle or a garment joined by welding, the surface
state of the joining part 60 between the first fabric 10 and the
second fabric 20 becomes a smooth state with little unevenness, and
the skin contact to the wearer of the garment 1 is improved.
[0052] The boundary between the first fabric 10 and the second
fabric 20 is preferably located in a central part of the
belt-shaped member 30, The expression "central part" of the
belt-shaped member 30 is referred to as the center region of the
width of belt-shaped member 30 divided into three equal regions. By
arranging the first fabric 10 and the second fabric 20 in such a
position of the belt-shaped member 30, the joining strength between
the first fabric 10 and the belt-shaped member 30 as well as the
joining strength between the second fabric 20 and the belt-shaped
member 30 can be enhanced, and the garment 1 that has favorable
production efficiency and excellent durability can be obtained.
[0053] As shown in FIG. 5, it is preferred to provide the
belt-shaped member 30 at a position on the boundary between the
front panel 2 and the back panel 3 in the side part, at a position
on the boundary between the front panel 2 and the back panel 3 in
the shoulder part, and at a position of an armhole 71. By providing
the belt-shaped member 30 at these positions, the garment 1 that
has favorable skin contact and is comfortable to the wearer can be
obtained.
[0054] At least one of the first fabric 10 and the second fabric 20
has a larger elongation in a direction perpendicular to a direction
parallel to a boundary line between the first fabric 10 and the
second fabric 20 (boundary line perpendicular direction D2) than an
elongation in the direction parallel to the boundary line between
the first fabric 10 and the second fabric 20 (boundary line
parallel direction D1). That is, at least one of the first fabric
10 and the second fabric 20 has a larger elongation in a
circumferential direction of the body of the wearer than an
elongation in a vertical direction that is a direction from the
head to the foot of the wearer. By constituting at least one of the
first fabric 10 and the second fabric 20 in this way, the garment 1
that is easily fitted to the body of the wearer is obtained. In the
present invention, "perpendicular" means 80 degrees-100 degrees. It
is not necessary to have the larger elongation in the boundary line
perpendicular direction D2 than in the boundary line parallel
direction D1 in all of 80 degrees-100 degrees, and the larger
elongation in the boundary line perpendicular direction D2 than in
the boundary line parallel direction D1 at an angle of the
identification of 80 degrees-100 degrees.
[0055] It is sufficient that at least one of the first fabric 10
and the second fabric 20 has a larger elongation in the boundary
line perpendicular direction D2 than an elongation in the boundary
line parallel direction D1; however, it is preferred that the first
fabric 10 and the second fabric 20 have a larger elongation in the
boundary line perpendicular direction D2 than an elongation in the
boundary line parallel direction D1. By constituting the first
fabric 10 and the second fabric 20 in this way, the stretchability
of the garment 1 can be further enhanced, and the garment 1 becomes
easy to follow the motion of the body of the wearer.
[0056] In the garment 1, the k.sub.tx and k.sub.ty that are
solutions of the following equations have a relationship of
k.sub.tx>k.sub.ty. In addition, the k.sub.b1x, k.sub.b1y,
k.sub.b2x, and k.sub.b2y that are solutions of the following
equations have a relationship of at least one of
k.sub.b1x<k.sub.b1y and k.sub.b2x<k.sub.b2y.
F.sub.x=L.sub.x{12k.sub.b1x.times.12k.sub.b2x/(12k.sub.b1x+12k.sub.b2x)+-
6k.sub.tx}
F.sub.y=L.sub.y(3k.sub.b1y+3k.sub.b2y+k.sub.ty)
F.sub.b1x=L.sub.b1x.times.6k.sub.b1x
F.sub.b2x=L.sub.b2x.times.6k.sub.b2x
F.sub.b1y=L.sub.b1y.times.6k.sub.b1y
F.sub.b2y=L.sub.b2y.times.6k.sub.b2y
[0057] In the above equations, F.sub.x represents a load (N)
applied in the boundary line perpendicular direction D2 to a part
in which the first fabric 10 and the second fabric 20 are laminated
to the belt-shaped member 30 (laminated part 61), L.sub.x
represents a displacement (mm) when a load is applied to the
laminated part 61 in the boundary line perpendicular direction D2,
F.sub.y represents a load (N) applied to the laminated part 61 in
the boundary line parallel direction D1, L.sub.y represents a
displacement (mm) when a load is applied to the laminated part 61
in the boundary line parallel direction D1, F.sub.b1x represents a
load (N) applied to the first fabric 10 in the boundary line
perpendicular direction D2, L.sub.b1x represents a displacement
(mm) when a load is applied to the first fabric 10 in the boundary
line perpendicular direction D2, F.sub.b2x represents a load (N)
applied to the second fabric 20 in the boundary line perpendicular
direction D2, L.sub.2x represents a displacement (mm) when a load
is applied to the second fabric 20 in the boundary line
perpendicular direction D2, F.sub.b1y represents a load (N) applied
to the first fabric 10 in the boundary line parallel direction D1,
L.sub.b1y represents a displacement (mm) when a load is applied to
the first fabric 10 in the boundary line parallel direction D1,
F.sub.b2y represents a load (N) applied to the second fabric 20 in
the boundary line parallel direction D1, and L.sub.b2y represents a
displacement (mm) when a load is applied to the second fabric 20 in
the boundary line parallel direction D1, respectively.
[0058] After the measurement of L.sub.x, L.sub.y, L.sub.b1x,
L.sub.b2x, L.sub.b1y, and L.sub.b2y, the k.sub.tx, k.sub.ty,
k.sub.b1x, k.sub.b1y, k.sub.b2x, and k.sub.b2y that are solutions
of the above equations are calculated, and a relationship between
the k.sub.tx and the k.sub.ty, a relationship between the k.sub.b1x
and the k.sub.b1y, and a relationship between the k.sub.b2x and the
k.sub.b2y are determined.
[0059] By having the fact that the k.sub.tx and k.sub.ty that are
solutions of the above equations satisfy a relationship of
k.sub.tx>k.sub.ty, and that the k.sub.b1x, k.sub.b1y, k.sub.b2x,
and k.sub.b2y satisfy a relationship of at least one of
k.sub.b1x<k.sub.b1y and k.sub.b2x<k.sub.b2y, the garment 1
that is excellent in the stretchability in the boundary part
between the first fabric 10 and the second fabric 20, easy to
follow the motion of the body of the wearer, and comfortable during
exercise can be obtained.
[0060] In addition, when a garment is made without sewing, in order
to make the garment beautifully finished, it is required to apply
tension to a fabric at the time of joining the fabric. If a fabric
having a high elongation is used in order to obtain a garment
having excellent stretchability, the fabric is excessively
elongated in the joining step of each fabric, and it may be
difficult to obtain a beautiful finish or may be insufficient in
the joining of each fabric. The k.sub.tx and k.sub.ty have a
relationship of k.sub.tx>k.sub.ty, whereas the k.sub.b1x,
k.sub.b1y, k.sub.b2x, and k.sub.b2y have a relationship of at least
one of k.sub.b17<k.sub.b1y and k.sub.b2x<k.sub.b2y, so that
the belt-shaped member 30 prevents the first fabric 10 and the
second fabric 20 from being excessively elongated, the joining
strength with the first fabric 10 and the second fabric 20 is
enhanced, and the production efficiency of the garment 1 can be
increased.
[0061] It is sufficient that the k.sub.b1x, k.sub.b1y, k.sub.b2x,
and k.sub.b2y have a relationship of at least one of
k.sub.b1x<k.sub.b1y and k.sub.b2x<k.sub.b2y; however, it is
preferred to have a relationship of k.sub.b1x<k.sub.b1y and
k.sub.b2x<k.sub.b2y. By having the fact that the k.sub.b1x,
k.sub.b1y, k.sub.b2x, and k.sub.b2y satisfy such a relationship,
the stretchability in the boundary part between the first fabric 10
and the second fabric 20 can be enhanced, and the garment 1 is
easily fitted to the body of the wearer. In addition, also in the
joining step of the first fabric 10 and the belt-shaped member 30
as well as the second fabric 20 and the belt-shaped member 30, the
joining is easily performed, and the productivity of the garment 1
can be enhanced.
[0062] In a case where the garment 1 has a hood 5, the hood 5 is
constituted of multiple fabrics, and the belt-shaped member 30 is
preferably arranged along the boundary between the fabrics. That
is, the belt-shaped member 30 is joined to each of the fabrics
constituting the hood 5, and each of the fabrics constituting the
hood 5 is preferably joined to each other with the belt-shaped
member 30. By constituting the hood 5 with multiple fabrics, the
hood 5 is easily fitted to the head of the wearer. By arranging the
belt-shaped member 30 along the boundary between the fabrics
constituting the hood 5, even when the hood 5 is fitted to the head
of the wearer, the surface of the joining part between the fabrics
constituting the hood 5 becomes smooth, and a sense of discomfort
is hardly given to the wearer.
[0063] In a case where the garment 1 has the hood 5, the
belt-shaped member 30 is preferably arranged along the boundary
between the hood 5 and the first fabric 10. That is, the fabric
constituting the hood 5 and the first fabric 10 are preferably
joined by the belt-shaped member 30. By arranging the belt-shaped
member 30 along the boundary between the hood 5 and the first
fabric 10, unevenness is hardly formed in the joining part between
the hood 5 and the first fabric 10, and the garment 1 that has
favorable skin contact can be obtained.
[0064] In a case where the garment 1 has the second fabric 20a on
the right side in a right front panel and the second fabric 20b on
the left side in a left front panel, the garment 1 may have an
engagement member engaging the second fabric 20a on the right side
with the second fabric 20b on the left side. Examples of the
engagement member include a zip fastener, and a hook and loop
fastener. In addition, the engagement member may be provided, for
example, in an opening of a pocket or the like of the garment 1. As
the method for joining the engagement member to the first fabric 10
or the second fabric 20, for example, sewing, welding by ultrasonic
waves or heat, bonding by an adhesive, or the like can be
mentioned. Among them, as the method for joining the engagement
member, sewing is preferred. By joining the engagement member to
the first fabric 10 or the second fabric 20 by sewing, the bonding
strength between the engagement member and the first fabric 10 or
second fabric 20 can be enhanced. Therefore, even if stress is
applied to the joining part between the engagement member and the
first fabric 10 or the second fabric 20 at the time of engaging or
separating the engagement member, the engagement member is hardly
removed from the first fabric 10 or the second fabric 20.
[0065] In this regard, in the joining part between the engagement
member and the first fabric 10 or the second fabric 20, it is
preferred to arrange a belt-shaped member 30. By arranging the
belt-shaped member 30 in the joining part between the engagement
member and the first fabric 10 or the second fabric 20, the surface
of the joining part of the engagement member is made smooth, and
the joining part of the engagement member hardly gives a sense of
discomfort to the body of the wearer.
[0066] The k.sub.tx k.sub.b1x and k.sub.b2x that are solutions of
the above equations preferably have a relationship of at least one
of k.sub.tx>k.sub.b1x and k.sub.tx>k.sub.b2x. By having the
fact that the k.sub.tx, k.sub.b1x and k.sub.b2x satisfy such a
relationship, the stretchability of the garment 1 is improved, and
the garment 1 that hardly hinders the motion of the body of the
wearer during exercise can be obtained. In addition, also in the
production of the garment 1, the joining part 60 between the first
fabric 10 and the second fabric 20 is prevented from being
excessively elongated, and the production efficiency of the garment
1 can be enhanced.
[0067] In addition, the k.sub.tx, k.sub.b1x and k.sub.b2x
preferably have a relationship of k.sub.tx>k.sub.b1x and
k.sub.tx>k.sub.b2x. By having the fact that the k.sub.tx,
k.sub.b1x and k.sub.b2x satisfy such a relationship, the
stretchability of the garment 1 can be further enhanced, and the
garment 1 becomes easy to follow the body of the wearer.
[0068] The k.sub.tx and k.sub.ty that are solutions of the above
equations have preferably a ratio of 1.5 or more, more preferably a
ratio of 1.7 or more, and furthermore preferably a ratio of 2 or
more. In this regard, the ratio of the k.sub.tx and k.sub.ty is
calculated by a calculation formula of k.sub.tx/k.sub.ty. By
setting the lower limit value of the ratio of the k.sub.tx and
k.sub.ty in this way, the stretchability in the joining part 60 is
enhanced, and the garment 1 that is easy to follow the body of the
wearer can be obtained. The upper limit value of the ratio of the
k.sub.tx and k.sub.ty is not particularly limited, and can be set
to be, for example, 10 or less, 8 or less, or 5 or less.
[0069] At least one of the first fabric 10 and the second fabric 20
has a ratio of an elongation in the boundary line perpendicular
direction D2 to an elongation in the boundary line parallel
direction D1 of preferably 1.5 or more, more preferably 1.7 or
more, and furthermore preferably 2 or more. In this regard, the
ratio of an elongation of the first fabric 10 in the boundary line
perpendicular direction D2 to an elongation of the first fabric 10
in the boundary line parallel direction D1 is calculated by a
calculation formula of the elongation [%] of the first fabric 10 in
the boundary line perpendicular direction D2/the elongation [%] of
the first fabric 10 in the boundary line parallel direction D1, and
the ratio of an elongation of the second fabric 20 in the boundary
line perpendicular direction D2 to an elongation of the second
fabric 20 in the boundary line parallel direction D1 is calculated
by a calculation formula of the elongation [%] of the second fabric
20 in the boundary line perpendicular direction D2/the elongation
[%] of the second fabric 20 in the boundary line parallel direction
D. By setting the lower limit value of the ratio of the elongation
of at least one of the first fabric 10 and the second fabric 20 in
the boundary line perpendicular direction D2 to the elongation of
at least one of the first fabric 10 and the second fabric 20 in the
boundary line parallel direction D1 in this way, the garment 1
becomes easy to follow the motion of exercise or the like when the
garment 1 is worn. The upper limit value of the ratio of the
elongation of at least one of the first fabric 10 and the second
fabric 20 in the boundary line perpendicular direction D2 to the
elongation of at least one of the first fabric 10 and the second
fabric 20 in the boundary line parallel direction D1 is not
particularly limited, but can be set to be, for example, 1.0 or
less, 8 or less, or 5 or less.
Embodiment 2
[0070] Hereinafter, a garment according to an embodiment 2 of the
present invention will be described with reference to the drawings.
Basically, the garment according to the embodiment 2 has a
constitution similar to the constitution of the garment according
to the embodiment 1, and therefore, the description of the common
parts will be omitted.
[0071] The garment 1 of the embodiment 2 of the present invention
is a garment 1 including a first fabric 10, a second fabric 20, and
a belt-shaped member 30, and is characterized in that the first
fabric 10 is in a back panel 3, the second fabric 20 is in a front
panel 2, at least one of the front panel 2 and the back panel 3
includes a fabric having a larger elongation than an elongation of
at least one of the first fabric 10 and the second fabric 20 in a
direction (hereinafter, also referred to as "boundary line
perpendicular direction D12") perpendicular to a direction parallel
to a boundary line between the first fabric 10 and the second
fabric 20 (hereinafter, also referred to as "boundary line parallel
direction D1") in at least a part of from a lower part of an
armhole 71 to a boundary between the first fabric 10 and the second
fabric 20, and the belt-shaped member 30 is arranged along the
armhole 71 of at least one of the first fabric 10 and the second
fabric 20,
[0072] As shown in FIG. 5, at least one of the front panel 2 and
the back panel. 3 includes a fabric 41 having a larger elongation
than the elongation of at least one of the first fabric 10 and the
second fabric 20 in the boundary line perpendicular direction D2,
in at least the part of from the lower part of the armhole 71 to
the boundary between the first fabric 10 and the second fabric 20.
The lower part of the armhole 71 of the garment 1 is a part in
which stress is easily applied to the fabric by the motion such as
swinging the arms during exercise such as jogging. Therefore, by
including the fabric 41 having a larger elongation than the
elongation of at least one of the first fabric 10 and the second
fabric 20 in the boundary line perpendicular direction D2, in at
least the part of from the lower part of the armhole 71 of the
garment 1 to the boundary between the first fabric 10 and the
second fabric 20, the fabric in the lower part of the armhole 71 is
prevented from being pulled during the exercise with the motion
such as swinging the arms, and thus the wear comfort of the garment
1 can be enhanced.
[0073] The fabric 41 having a larger elongation than the elongation
of at least one of the first fabric 10 and the second fabric 20 in
the boundary line perpendicular direction D12 preferably has a
larger elongation than an elongation of each of the first fabric 10
and the second fabric 20 in the boundary line perpendicular
direction D2. By constituting the fabric 41 having a larger
elongation than the elongation of at least one of the first fabric
10 and the second fabric 20 in the boundary line perpendicular
direction D2 in this way, the stretchability of the armhole 71 can
be further enhanced, and the wear comfort of the garment 1 during
exercise can be enhanced.
[0074] As the method for forming the fabric 41 having a larger
elongation than the elongation of at least one of the first fabric
10 and the second fabric 20 in the boundary line perpendicular
direction D2, for example, a method of forming a knit structure or
weave structure having higher stretchability than the
stretchability of at least one of the first fabric 10 and the
second fabric 20, a method of using a material having higher
stretchability than the stretchability of at least one of the first
fabric 10 and the second fabric 20, or the like can be
mentioned.
[0075] The fabric 41 having a larger elongation than the elongation
of at least one of the first fabric 10 and the second fabric 20 in
the boundary line perpendicular direction D2 may be joined to at
least one of the first fabric 10 in the back panel 3 and the second
fabric 2 in the front panel 2 by welding, sewing, or the like, and
it is preferred that the fabric 41 having a larger elongation than
the elongation of at least one of the first fabric 10 and the
second fabric 20 in the boundary line perpendicular direction D2 is
included in the fabric constituting at least one of the first
fabric 10 and the second fabric 20, by partially changing the knit
structure or weave structure of at least one of the first fabric 10
and the second fabric 20. That is, the fabric 41 having a larger
elongation than the elongation of at least one of the first fabric
10 and the second fabric 20 in the boundary line perpendicular
direction D2, and at least one of the first fabric 10 and the
second fabric 20 are preferably integrally constituted. By
constituting the fabric 41 having a larger elongation than the
elongation of at least one of the first fabric 10 and the second
fabric 20 in the boundary line perpendicular direction D2 and at
least one of the first fabric 10 and the second fabric 20 in this
way, unevenness or the like due to the joining is hardly formed in
the boundary part of the fabric 41 having a larger elongation than
the elongation of at least one of the first fabric 10 and the
second fabric 20 in the boundary line perpendicular direction D2,
and therefore, the garment 1 that has favorable skin contact can be
obtained.
[0076] The fabric 41 having a larger elongation than the elongation
of at least one of the first fabric 10 and the second fabric 20 in
the boundary line perpendicular direction D2 preferably has higher
air-permeability than the air-permeability of at least one of the
first fabric 10 and the second fabric 20. Since heat is easy to be
accumulated between the fabric in the lower part of the armhole 71
and the wearer, for example, use of a fabric 41a having higher
air-permeability than the air-permeability of at least one of the
first fabric 10 and the second fabric 20, such as a mesh knit
fabric, as the fabric 41 having a larger elongation than the
elongation of at least one of the first fabric 10 and the second
fabric 20 in the boundary line perpendicular direction D2 can
improve the wear comfort of the garment 1.
[0077] The belt-shaped member 30 is arranged along the armhole 71
of at least one of the first fabric 10 and the second fabric 20.
Since the armhole 71 is a part that comes into contact with the
side of the wearer, particularly, it is required to improve the
skin contact in this part. By arranging the belt-shaped member 30
along the armhole 71 of at least one of the first fabric 10 and the
second fabric 20, the surface of the armhole 71 is made smooth, and
the garment 1 that is comfortable to the wearer can be
obtained.
[0078] The first fabric 10 and the second fabric 20 preferably have
knit structures different from each other. By forming the knit
structures of the first fabric 10 and the second fabric 20
different from each other, a function suitable for each part of the
garment 1 can be imparted. For example, since heat is easy to be
accumulated in a back part of an upper garment that is the garment
1, use of a knit structure having high air-permeability such as
mesh knitting for the first fabric 10 in the back panel 3 can be
mentioned.
[0079] At least one of the first fabric 10 and the second fabric 20
preferably has multiple knit structures. Specifically, for example,
a constitution in which multiple different kinds of knit structures
such as rib knitting and mesh knitting are included in the first
fabric 10 can be mentioned. By including multiple knit structures
in at least one of the first fabric 10 and the second fabric 20,
adequate characteristics can be imparted to each part of the first
fabric 10 or the second fabric 20. For example, by forming the
whole knit structure of the first fabric 10 with rib knitting, the
whole stretchability of the first fabric 10 is enhanced, and the
first fabric 10 is fitted to the body of the wearer, and further,
by forming the knit structure in the vicinity of the side of the
first fabric 10 with mesh knitting, the air-permeability in the
vicinity of the side in which heat is easy to be accumulated is
enhanced, and thus the wear comfort of the garment 1 can be
improved.
[0080] It is preferred that at least one of the first fabric 10 and
the second fabric 20 has multiple knit structures, and it is more
preferred that each of the first fabric 10 and the second fabric 20
has multiple knit structures, By including multiple knit structures
in each of the first fabric 10 and the second fabric 20, a function
that is required in each part in the whole body of the wearer can
be imparted, and a more functional garment can be obtained as the
garment 1.
[0081] A fabric 41b having a larger elongation than the elongation
of the first fabric 10 in the boundary line perpendicular direction
D2 is preferably included in the central part of the back panel. By
constituting the back panel 3 in this way, the stretchability in
the back part of an upper garment that is the garment 1 is
enhanced, and the upper garment that is fitted to the wearer can be
obtained.
[0082] The fabric 41b having a larger elongation than the
elongation of the first fabric 10 in the boundary line
perpendicular direction D2 may be arranged in a shoulder part of
the second fabric 20. By constituting the second fabric 20 in this
way, the stretchability can be imparted to the fabric in the
shoulder part of the front panel 2, which is easily pulled
according to the pulling of fabric at the time of motion such as
turning the arm, and thus the garment 1 that has favorable wearing
feeling can be obtained.
[0083] FIG. 6 shows a plan view of a sleeve fabric 50 constituting
the sleeve 4 of the garment 1. As shown in FIG. 6, it is preferred
to include a longitudinal perpendicular direction extension part 51
having a larger elongation in a longitudinal direction D3 of the
sleeve 4 than an elongation in a direction D4 perpendicular to the
longitudinal direction of the sleeve 4, in a part located in an
elbow part when worn. By constituting the sleeve 4 of the garment 1
in such a way, the fabric in the elbow part of the sleeve 4 is
stretched at the time of motion of bending the elbow, and thus the
garment 1 hardly hinders the motion of the wearer.
[0084] It is preferred to include a longitudinal direction
extension part 52 having a larger elongation in the direction D4
perpendicular to the longitudinal direction D3 of the sleeve 4 than
the elongation in the longitudinal direction of the sleeve 4, on
both of the upper and lower sides in the longitudinal direction of
the sleeve 4 in the longitudinal perpendicular direction extension
part 51. With the garment 1 having the sleeve 4 that is constituted
in this way, the sleeve 4 is fitted to the arm of the wearer, and
thus can follow the motion of the wearer.
[0085] As the longitudinal perpendicular direction extension part
51, for example, a knit structure of garter knitting or the like
can be used. In addition, as the longitudinal direction extension
part 52, for example, a knit structure of rib knitting or the like
can be used.
[0086] As for the longitudinal perpendicular direction extension
part 51 and the longitudinal direction extension part 52, a fabric
constituting the longitudinal perpendicular direction extension
part 51 and a fabric constituting the longitudinal direction
extension part 52 may be joined to the sleeve fabric 50 by welding,
sewing, or the like; however, it is preferred that by partially
changing the knit structure or weave structure of the sleeve fabric
50, the longitudinal perpendicular direction extension part 51 and
the longitudinal direction extension part 52 are included in a
fabric constituting the sleeve fabric 50. That is, the sleeve
fabric 50, the longitudinal perpendicular direction extension part
51 and the longitudinal direction extension part 52 are preferably
integrally constituted. By constituting the sleeve fabric 50 in
this way, the unevenness due to the joining can be reduced in each
of the boundary parts between the sleeve fabric 50 and the
longitudinal perpendicular direction extension part 51, and between
the sleeve fabric 50 and the longitudinal direction extension part
52, and therefore, the skin contact of the sleeve 4 can be
improved.
[0087] The fabric constituting the sleeve fabric 50 preferably has
a larger elongation in the longitudinal direction D3 of the sleeve
4 than the elongation in the direction D4 perpendicular to the
longitudinal direction.
[0088] By constituting the sleeve fabric 50 in this way, a sleeve 4
having high followability to the arm during exercise of swinging
the arms back and forth, such as jogging can be obtained. As a
result, cuffs are hardly turned up during exercise.
[0089] It is preferred that the garment 1 has a sleeve, the sleeve
contains a rib knitting part 53, and a longitudinal direction of a
furrow 53a of the rib knitting part 53 is not parallel to an axial
direction of the sleeve. The expression "axis direction of the
sleeve" is referred to as an extending direction of the axis
passing through a plane A containing at least a part of a lower end
part of a cuff of the sleeve, and a plane B containing an upper end
part of the sleeve and being parallel to the plane A. The
expression. "longitudinal direction of a furrow 53a of the rib
knitting part 53 is not parallel to an axial direction of the
sleeve" is referred to as an angle of exceeding 0 degree formed by
the longitudinal direction of the furrow 53a of the rib knitting
part 53 and the axis direction of the sleeve. By constituting the
sleeve in this way, the sleeve becomes easy to follow the motion of
putting the arm forward. Therefore, during exercise of swinging the
arms back and forth, the garment 1 that is particularly comfortable
to the wearer can be obtained.
[0090] The angle formed by the longitudinal direction of the furrow
53a of the rib knitting part 53 and the axis direction of the
sleeve is preferably 1 or more degrees, more preferably 3 or more
degrees, and furthermore preferably 5 or more degrees. By setting
the lower limit value of the angle formed by the longitudinal
direction of the furrow 53a of the rib knitting part 53 and the
axis direction of the sleeve in this way, the sleeve becomes easy
to follow the motion of swinging the arms back and forth, and thus
the wear comfort of the garment 1 during exercise can be enhanced.
The angle formed by the longitudinal direction of the furrow 53a of
the rib knitting part 53 and the axis direction of the sleeve is
preferably 45 or less degrees, more preferably 40 or less degrees,
and furthermore preferably 35 or less degrees. By setting the upper
limit value of the angle formed by the longitudinal direction of
the furrow 53a of the rib knitting part 53 and the axis direction
of the sleeve in this way, the lower part of the sleeve is easily
fitted to the forearm of the wearer.
[0091] Hereinafter, preferred embodiments of the garment according
to the embodiment 1 and the embodiment 2 of the present invention
will be described.
[0092] The garment 1 is preferably an outer garment or an
intermediate garment. The outer garment is a garment to be worn
outermost, and the intermediate garment is a garment to be worn
intermediately between an outer garment and an inner garment. The
garment 1 is an outer garment or an intermediate garment, and it is
preferred to wear, for example, underwear or the like that has
favorable water absorbency on the inner side of the garment 1.
[0093] The first fabric 10 and the second fabric 20 are preferably
joined by welding. Examples of the welding include heat welding,
and ultrasonic welding. By joining the first fabric 10 and the
second fabric 20 by welding, the joining strength with the first
fabric 10 and the second fabric 20 can be enhanced, and the
durability of the garment 1 can be enhanced.
[0094] The belt-shaped member 30 is preferably pasted in the
joining part 60 in which the first fabric 10 and the second fabric
20 are joined by welding. By welding the first fabric 10 and the
second fabric 20, a material constituting the first fabric 10 and a
material constituting the second fabric 20 are melted and
solidified, and therefore, the joining part 60 becomes hard, and
the skin touch becomes poor. By pasting the belt-shaped member 30
to the joining part 60, the joining part 60 having poor skin touch
is covered with the belt-shaped member 30, and thus the discomfort
feeling is hardly given to the wearer when wearing the garment
1.
EXAMPLES
[0095] Hereinafter, the effects of the present invention will be
specifically described by way of example. The following example
does not limit the present invention, and all of the design changes
according to the gist of the foregoing or following description are
included in the technical scope of the present invention.
[0096] By using the first fabric 10 shown in FIG. 3 and the second
fabric 20 (20a, 20b) shown in FIG. 4, the first fabric 10 and the
second fabric 20 were joined by ultrasonic welding as shown in FIG.
5. The belt-shaped member 30 was arranged and pasted in the joining
part 60 between the first fabric 10 and the second fabric 20, and
the garment 1 was produced. A base part of each of the first fabric
10 and the second fabric 20 was set to be a rib knit structure, the
fabric 41a having higher air-permeability than the air-permeability
of at least one of the first fabric 10 and the second fabric 20 was
set to be a mesh knit structure, and the fabric 41b having a larger
elongation than the elongation of the first fabric 10 in the
boundary line perpendicular direction D2 was set to be a thick rib
knit structure in which the rib width was larger than the rib width
of the base part of each of the first fabric 10 and the second
fabric 20. The width of the belt-shaped member 30 was 10 mm. In
addition, the thickness of the base part of each of the first
fabric 10 and the second fabric 20 was 1.45 mm.
[0097] From the base part of the first fabric 10 in the back panel
3 of the garment 1, a measurement sample of the first fabric 10 was
collected along the boundary line parallel direction D1 and the
boundary line perpendicular direction D2. From the laminated part
61 being the joining part 60 between the first fabric 10 and the
second fabric 20, in which the first fabric 10 and the second
fabric 20 were laminated to the belt-shaped member 30, a
measurement sample of the laminated part 61 was collected along the
boundary line parallel direction D1 and the boundary line
perpendicular direction D2 so as to have the laminated part 61 at
the center. The size of each measurement sample was 160 to 180 mm
in length and 60 mm in width. Note that in the present example,
since the knit structures of the base parts of the first fabric 10
and the second fabric 20 are the same, the measurement sample of
the first fabric 10 also serves as the measurement sample of the
second fabric 20. In a case where the knit structures of the base
parts of the first fabric 10 and the second fabric 20 are
different, a measurement sample of the second fabric 20 was
collected from the base part of the second fabric 20 in the front
panel 2.
[0098] A mark was made at the longitudinal center of each
measurement sample such that the size of the measurement sample in
length was the same as the size of the belt-shaped member 30 in
width. In the present example, since the belt-shaped member 30
having a width of 10 mm was used, the marks were made at intervals
(hereinafter referred to as the point distance) of 10 mm.
[0099] By using a tensile testing machine, the measurement sample
of the first fabric 10 was pulled in the boundary line parallel
direction D1, and a displacement L.sub.b1y of the measurement
sample of the first fabric 10 in the boundary line parallel
direction D1 was measured. Specifically, the measurement sample of
the first fabric 10 was fixed to a gripping tool such that the
distance between the gripping tools was 100 mm, a load F.sub.b1y
was applied to the measurement sample of the first fabric 10 in the
boundary line parallel direction D1, and the increased distance of
the point distance between the marks made to the measurement sample
of the first fabric 10 was measured. The tensile rate of the
measurement sample of the first fabric 10 was set to be 200 mm/min.
As the measurement device, for example, Table-Top Type Autograph
AGS-X 1 kN manufactured by Shimadzu Corporation can be used.
[0100] In a similar manner as in the measurement of the
displacement L.sub.b1y of the measurement sample of the first
fabric 10 in the boundary line parallel direction D1, a
displacement L.sub.b1x of the measurement sample of the first
fabric 10 in the boundary line perpendicular direction D2, a
displacement L.sub.y of the measurement sample of the laminated
part 61 in the boundary line parallel direction D1, and a
displacement L.sub.x of the measurement sample of the laminated
part 61 in the boundary line perpendicular direction D2 were
measured. The measurement results are shown in Table 1.

[0101] The loads of F.sub.b1y, F.sub.b1x, F.sub.y, and F.sub.x
applied to the measurement sample and the displacements of
L.sub.b1y, L.sub.b1x, L.sub.y, and L.sub.x were substituted into
the following equations, and the k.sub.tx, k.sub.ty, k.sub.b1x, and
k.sub.b1y that are solutions of the following equations were
calculated. As described above, in the present example, the knit
structures of the base parts of the first fabric 10 and the second
fabric 20 were the same. Therefore, it was considered that the
values of the k.sub.b1x and k.sub.b1y being solutions of the
equations for the first fabric 10 were the same as the values of
k.sub.b2x and k.sub.b2y, and the measurement of displacement and
the calculation of solution were performed for the measurement
sample of the first fabric 10. In a case where the knit structures
of the base parts of the first fabric 10 and the second fabric 20
were different, also for the second fabric 20, similarly as in the
first fabric 10, the loads of F.sub.b2y and F.sub.b2y, were applied
to the measurement sample of the second fabric 20, and the
displacements of L.sub.b2y and L.sub.b2x were measured and the
solutions of k.sub.b2x and k.sub.b2y were calculated.
F.sub.x=L.sub.x{12k.sub.b1x.times.12k.sub.b2x/(12k.sub.b1x+12k.sub.b2x)+-
6k.sub.tx}
F.sub.y=L.sub.y(3k.sub.b1y+3k.sub.b2y+k.sub.ty)
F.sub.b1x=L.sub.b1x.times.6k.sub.b1x
F.sub.b1y=L.sub.b1y.times.6k.sub.b1y
[0102] FIGS. 7 to 10 are graphs showing the displacement when a
load is applied to respective measurement samples. As shown in FIG.
7, the displacement L.sub.b1y was 3.4 mm when a load F.sub.b1y of
10 N was applied to the measurement sample of the first fabric 10
in the boundary line parallel direction D1. As a result,
k.sub.b1y=0.49 was obtained from
F.sub.b1y=L.sub.b1y.times.6k.sub.b1y.
[0103] As shown in FIG. 8, the displacement L.sub.b1x was 9.1 mm
when a load F.sub.b1x of 10 N was applied to the measurement sample
of the first fabric 10 in the boundary line perpendicular direction
D2. As a result, k.sub.b1x=0.18 was obtained from
F.sub.b1x=L.sub.b1x.times.6k.sub.b1x.
[0104] As shown in FIG. 9, the displacement L.sub.y was 2.8 mm when
a load F.sub.y of 10 N was applied to the measurement sample of the
laminated fabric 61 in the boundary line parallel direction D1. As
a result, k.sub.ty=0.63 was obtained from
F.sub.y=L.sub.y(3k.sub.b1y+3k.sub.b2y+k.sub.ty).
[0105] As shown in FIG. 10, the displacement L.sub.x was 1.0 mm
when a load F.sub.x of 10 N was applied to the measurement sample
of the laminated fabric 61 in the boundary line perpendicular
direction D2. As a result, k.sub.tx=1.54 was obtained from
F=L.sub.x{12k.sub.b1x.times.12k.sub.b2x/(12k.sub.b1x+12k.sub.b2x)+6k.sub.-
tx}.
[0106] From the calculated k.sub.tx, k.sub.ty, k.sub.b1x, and
k.sub.b1y, a relationship of k.sub.tx>k.sub.ty, and further a
relationship of k.sub.b1x<k.sub.b1y are obtained. Therefore, the
garment 1 of the present example is excellent in the stretchability
in the boundary part between the first fabric 10 and the second
fabric 20, and becomes comfortable to the wearer particularly
during exercise.
