Description
TECHNICAL FIELD
[0001] The present invention relates to clothes, and more
particularly to functional sportswear, which may assist the easy
judgment of a foul in sports in which body contact frequently
occurs, such as football, basketball, and handball.
BACKGROUND ART
[0002] Because sports, such as football, basketball, and handball,
entail body contact at a very high frequency and are characterized
by personal fouls that occur often and instantaneously, referees
have difficulty in judgment thereof. In particular, there are many
kinds of personal foul, such as, for example, a foul in which a
player purposely pulls opponent's sportswear top or bottoms such
that the referee cannot see the foul, and the outcome of the game
may often be decided by these personal fouls.
[0003] Although attempts have been made to use video replays in
order to alleviate the problem described above and such video
replays are used in some areas, many games are still played only
under referee judgment because the use of video may be problematic
in consideration of practical conditions including game
characteristics, etc.
[0004] In addition, in the case of a game officiated by only a few
referees, such as an amateur game, the referees have great
difficulty in recognizing a foul in which a player pulls opponent's
sportswear top or bottoms.
[0005] Hence, an enthusiastic response is expected from all parties
concerned if there is provided sportswear that assists referees in
immediately recognizing personal fouls, such as, for example, a
foul in which a player purposely and forcefully pulls opponent's
sportswear top or bottoms in a game that entails body contact at a
high frequency, and that may aid in the prevention of such personal
fouls.
DISCLOSURE
Technical Problem
[0006] Therefore, it is an object of the present invention to
provide functional sportswear, which may assist the easy judgment
of a foul in sports in which body contact frequently occurs, such
as football, basketball, and handball.
Technical Solution
[0007] In accordance with one aspect of the present invention, the
above and other objects can be accomplished by the provision of

is formed of a twisted yarn including a frangible fiber yarn 14,
which has a lower tensile strength than a polyester fiber yarn for
a sewing thread, and a soluble yarn 16, and wherein the soluble
yarn 16 is dissolved and removed after weaving using the sewing
thread, whereby the frangible fiber yarn 14 remains in the
ripping-line sewing thread 12 that sews the ripping lines 6 and
8.
[0008] In accordance with another aspect of the present invention,
there are provided functional sportswear top or bottoms having
ripping lines, wherein ripping lines 6 and 8 are patterned by
cutting a portion of a fibrous sportswear top 2 or fibrous
sportswear bottoms 2A so as to form one or more pieces 10, and
sewing adjacent pieces 10 to each other and sewing respective
pieces 10 to cut portions adjacent thereto using a ripping-line
sewing thread 12, which has a lower tensile strength than a tensile
strength of a typical sewing thread, in a zigzag form, and wherein
the ripping-line sewing thread 12 is formed of a frangible fiber
yarn 14, which has a lower tensile strength than a polyester fiber

line 6 has been removed, in a state in which a sheath of the low
melting point yarn 20 is melted via thermal treatment after the
weaving of the sportswear top 2 and a core 20a of the low melting
point thread 20 remains.
Advantageous Effects
[0010] According to the present invention, ripping lines are formed
in sportswear top or bottoms so that the sportswear top or bottoms
are ripped along the ripping lines when, for example, a foul in
which a player purposely and forcefully pulls opponent's sportswear
top or bottoms in a game that entails body contact at a high
frequency, thereby assisting referees in immediately recognizing
the foul and in making a judgment and preemptively alerting other
players that the sportswear top or bottoms have this ripping
function, which may advantageously prevent or minimize the
incidence of personal fouls. Advantageously, the ripped sportswear
may be reused as needed by being repaired and sewed using
ripping-line sewing threads so that the ripping lines are
restored.

BEST MODE
[0021] Hereinafter, exemplary embodiments of the present invention
will be described in detail with reference to the accompanying
drawings.
[0022] In the present invention, sportswear top or bottoms are
patterned with ripping lines so as to be ripped when pulled by any
person, including an opposing player, with strong force even though
they are fibrous sportswear top or bottoms woven with warps and
wefts, rather than paper or non-woven fabric.
[0023] FIG. 1 is a perspective view illustrating a fibrous
functional sportswear top 2 in accordance with an embodiment of the
present invention, and FIG. 9 is a perspective view illustrating
fibrous functional sportswear bottoms 2A in accordance with an
embodiment of the present invention.
[0024] In addition, FIG. 2 is an enlarged view illustrating
horizontal and vertical ripping lines 6 and 8 patterned in the back
portion 4 of the sportswear top 2 illustrated in FIG. 1 or the back
portion 4 of the sportswear bottoms 2A illustrated in FIG. 9.
[0025] In the embodiments of the present invention, the ripping
lines 6 and 8 illustrated in FIGS. 1 and 9 are patterned in a
portion of the sportswear top 2 or the sportswear bottoms 2A that
may be easily pulled by a game opponent, and more particularly, in
the back portion 4 of the sportswear top 2 or the sportswear
bottoms 2A.
[0026] The ripping lines 6 and 8 of the present invention have a
considerably lower tearing strength than the tearing strength of
the sportswear top 2 or the sportswear bottoms 2A, and serve as
lines at which tears will form when an opposing player forcefully
pulls the sportswear top 2 or the sportswear bottoms 2A.
[0027] In a first embodiment of the present invention, the ripping
lines 6 and 8, formed in the back portion 4 of the sportswear top 2
or the sportswear bottoms 2A, are acquired by cutting a portion of
the sportswear top 2 or the sportswear bottoms 2A, such as, for
example, the back portion 4, so as to form one or more pieces 10,
and sewing adjacent pieces 10 to each other and sewing respective
pieces 10 and cut portions to each other using a ripping-line
sewing thread 12, which has a lower tensile strength than the
tensile strength of a typical sewing thread, in a zigzag form as
illustrated in FIG. 2.
[0028] In the formation of the ripping-line sewing thread 12 sewed
in the zigzag form in accordance with the present invention, the
ripping-line sewing thread 12 is formed of a twisted yarn
illustrated in FIG. 3, which is formed by twisting a frangible
fiber yarn 14, which has a considerably lower tensile strength than
that of a typical polyester fiber yarn, and an additional soluble
yarn 16 with each other.
[0029] The frangible fiber yarn 14, which is one constituent
element of the ripping-line sewing thread 12, may be, for example,
cotton yarn or rayon yarn, and may be referred to as a fine yarn in
terms of thickness. The fine yarn has a metric thread count of 60
or more, and has a thickness of 100 denier or less, and more
particularly, a thickness of 20-60 denier.
[0030] In addition, the soluble yarn 16, which is the other
constituent element of the ripping-line sewing thread 12, is a
fiber yarn that will be dissolved in an elution solution to thereby
be removed from the ripping-line sewing thread 12, which sews the
horizontal and vertical ripping lines 6 and 8 after the sportswear
top 2 or the sportswear bottoms 2A are completely woven. The
soluble yarn 16 is formed of, for example, Poly Lactic Acid (PLA)
or Poly Vinyl Alcohol (PVA).
[0031] PVA, which is the material of the soluble yarn 16, is
expensive, but is dissolved in water, which is freely available. In
addition, PLA, which is the material of the soluble yarn 16, is
suitable in industrial and environmental terms. Such PLA is also
called corn fiber, and is environment-friendly and biodegradable
and is dissolved in an alkali solvent at a temperature of about 120
to 180 degrees Celsius. Hence, when the soluble yarn 16 is formed
of PVA, the elution solution is water. When the soluble yarn 16 is
formed of PLA, the elution solution is an alkali solvent.
[0032] In the present invention, the reason why the ripping-line
sewing thread 12 is formed of the twisted yarn including the
frangible fiber yarn 14 and the soluble yarn 16 is to substantially
prevent the breakage of the thread during zigzag sewing for the
formation of the ripping lines 6 and 8.
[0033] In FIG. 2, the dotted circle designated by "A" shows, on an
enlarged scale, the state in which the ripping-line sewing thread
12, which is formed of the twisted yarn including the frangible
fiber yarn 14 and the soluble yarn 16, is sewed in the zigzag
form.
[0034] Once the functional sportswear top 2 or the functional
sportswear bottoms 2A have been completely woven via sewing using
the sewing thread 12, which is formed of the twisted yarn including
the frangible fiber yarn 14 and the soluble yarn 16, the soluble
yarn 16 is dissolved in an elution solution and removed from the
thread 12 sewed in the zigzag form, whereby only the frangible
fiber yarn 14 remains in the ripping-line sewing thread 12, which
sews the ripping lines 6 and 8. This allows the ripping lines 6 and
8, which are sewed using soft yarns, to be considerably easily
ripped when, for example, an opposing player pulls the sportswear
top 2 or the sportswear bottoms 2A with strong force.
[0035] In FIG. 2, the dotted circle designated by "B" shows, on an
enlarged scale, the state in which the soluble yarn 16 has been
removed from the ripping-line sewing thread 12 sewed in the zigzag
form, and only the frangible fiber yarn 14 remains.
[0036] Meanwhile, although the ripping-line sewing thread 12 may be
formed of the twisted yarn including the frangible fiber yarn 14
and the soluble yarn 16 in accordance with the exemplary embodiment
of the present invention, in an alternative embodiment, the
ripping-line sewing thread 12 may be formed of only the frangible
fiber yarn 14 without the soluble yarn 16.
[0037] At this time, prevention of the breakage of the ripping-line
sewing thread 12 during sewing may be achieved by adjusting the
tension of a thread in a sewing machine or increasing the twist
factor of the ripping-line sewing thread 12. In addition, the
ripping-line sewing thread 12 may be slightly thicker than the
frangible fiber yarn 14 of the twisted yarn.
[0038] When the horizontal and vertical ripping lines 6 and 8 are
formed in the functional sportswear top 2 or the functional
sportswear bottoms 2A of the present invention as described above,
the ripping lines 6 and 8, which are sewed using soft yarns, may be
easily ripped when, for example, an opposing player pulls the
sportswear top 2 or the sportswear bottoms 2A with strong force. In
particular, when the frangible fiber yarn 14 of the ripping-line
sewing thread 12 is formed of rayon yarn, the frangible fiber yarn
14 is useful in that it is easily ripped by an opponent's pulling
force during a game because the tensile force of the frangible
fiber yarn 14 may be reduced by sweat due to the properties of
rayon.
[0039] FIGS. 4 and 10 are perspective views illustrating the state
in which a portion of the functional sportswear top 2 or the
functional sportswear bottoms 2A of the present invention is
ripped. When the sportswear is ripped or the ripped piece 10 is
separated, a referee can immediately recognize that an opposing
player has made an intentional foul, and can be aided in performing
referee judgment.
[0040] The functional sportswear top 2 or the functional sportswear
bottoms 2A described above are reusable by repairing and sewing the
ripped piece 10 after the game ends, and in the repair and sewing
stage, the horizontal and vertical ripping lines 6 and 8 may again
be sewed using soft yarns, which may be easily ripped, in a zigzag
form.
[0041] Meanwhile, FIGS. 5 to 8 are views related to horizontal and
vertical ripping lines formed in functional sportswear top or
bottoms in accordance with a second embodiment of the present
invention.
[0042] FIG. 5 is an enlarged view illustrating the horizontal and
vertical ripping lines in accordance with the second embodiment of
the present invention, FIG. 6 is a view illustrating major fibrous
tissues for the manufacture of the functional sportswear top or
bottoms in accordance with the second embodiment of the present
invention illustrated in FIG. 5, FIG. 7 is a view illustrating
major fibrous tissues provided with the horizontal and vertical
ripping lines 6 and 8 in accordance with the second embodiment of
the present invention, and FIG. 8 is a perspective view
illustrating the core 20a of a low melting point yarn 20 exposed at
the position of the horizontal ripping line 6 illustrated in FIG.
7.
[0043] In the second embodiment of the present invention, the
ripping lines 6 and 8, formed in the back portion 4 of the
sportswear top 2 or the sportswear bottoms 2A, are horizontal and
vertical gap lines, which cross each other and are generated by
dissolving and removing woven soluble yarns 21 and 24 (see FIG.
6).
[0044] FIG. 6 shows the configuration of major fibrous tissues for
the manufacture of the functional sportswear top 2 in accordance
with the present invention. More specifically, FIG. 6 shows fibrous
tissues for the formation of the ripping lines 6 and 8 acquired via
the removal of the soluble yarns 21 and 24.
[0045] In the second embodiment of the present invention, in order
to form the ripping line 6 by removing the soluble yarn 24, which
is included as a weft, the soluble yarn 24 for the formation of the
horizontal ripping line 6 and typical fiber yarns 22 for weaving
the sportswear top 2 or the sportswear bottoms 2A are used as wefts
of fabric fiber yarns. In addition, the soluble yarn 21 for the
formation of the vertical ripping line 8 and low melting point
yarns 20 may be used as warps of the fabric fiber yarns. In
addition, the warps including the low melting point yarns 20 are
thinner than the wefts.
[0046] In the present invention, the soluble yarns 21 and 24, which
are included to form some warps and wefts, are fiber yarns that are
dissolved and removed in an elution solution in order to form the
horizontal and vertical ripping lines 6 and 8 after the sportswear
top 2 is completely woven. The soluble yarns 21 and 24 may be
formed of, for example, Poly Lactic Acid (PLA) or Poly Vinyl
Alcohol (PVA).
[0047] The low melting point yarn (also referred to as an LM yarn
or low temperature melting yarn), which may be used as the warp in
the functional sportswear top 2 or the functional sportswear
bottoms 2A, is a fiber yarn consisting of a core, which is formed
of polyester and has a melting point within a range from 250 to 260
degrees Celsius, which corresponds to the melting point of typical
polyester, and a sheath, which has a considerably lower melting
point within a range from 120 to 200 degrees Celsius.
[0048] Hence, when the functional sportswear top 2 or the
functional sportswear bottoms 2A are thermally treated at the
temperature of 150 to 200 degrees Celsius after the soluble yarn 24
is dissolved and removed, in the case of the low melting point yarn
20, which is the warp, the sheath thereof, which is formed of a low
melting point material, is melted, causing the core 20a to be
exposed in the gap from which the soluble yarn 24 has been removed,
as illustrated in FIG. 8.
[0049] The horizontal ripping line 6 is formed as illustrated in
FIG. 1 or FIG. 9 in such a manner that the soluble yarn 24, which
is included as the weft, is dissolved and removed and the warp has
a reduced thickness. The horizontal ripping line 6 may be easily
ripped when an opposing player pulls the top 2 or the bottoms 2A
with strong force, even though it is not readily visible at other
times.
[0050] In the second embodiment of the present invention, in order
to form the vertical ripping line 8 via the removal of the soluble
yarn 21, which is included as a warp, it is necessary to supply two
kinds of warps using two warp supply units. For example, a first
warp supply unit, which supplies a plurality of warps, such as low
melting point yarns all at once may be a warp beam, and a second
warp supply unit, which supplies a warp, such as the soluble yarn
21, may be a creel.
[0051] The vertical ripping line 8 is formed using an elution
solution after the completion of weaving, in the same manner as the
horizontal ripping line 6. Once the vertical ripping line 8 has
been formed, the typical fiber yarn 22, which is included as the
weft, is exposed from the resulting gap.
[0052] With the configuration of the horizontal and vertical
ripping lines 6 and 8 formed as described above, when, for example,
an opposing player pulls the sportswear top 2 or the sportswear
bottoms 2A with strong force, the ripping line 6 in which the core
20a of the low melting point yarn 20, which is the warp, is exposed
may be considerably easily ripped. Once the horizontal ripping line
6 has been ripped, the vertical ripping line 8 may also be easily
ripped by inertia.
[0053] Although the above description of the present invention has
been made with reference to concrete embodiments, such as
sportswear, several alterations, such as, for example, the
application of the present invention to general garments, may be
practiced without deviating from the scope of the present
invention. Accordingly, the scope of the present invention should
be determined by the claims and equivalents thereof, rather than
being determined by the embodiments described above.
INDUSTRIAL APPLICABILITY
[0054] The present invention may be used in the manufacture of
functional sportswear top or functional sportswear bottoms, which
may assist the easy judgment of a foul in sports in which body
contact frequently occurs, such as football, basketball, and
handball.
