[0037] Since consumers expect functional clothing to provide more
and more functions, such as antibacterial, keeping warming,
absorbing moisture, repelling water, the appearance of the clothing
is also required by the consumers. The present invention provides a
color changeable textile, which has different colors at the front
yarn layer and the rear yarn layer respectively. When there is no
external force applied on the color changeable textile, the color
changeable textile shows the color of the front yarn layer; when
the color changeable textile is stretched, the color of the rear
yarn layer (or a pattern) is revealed while the color changeable
textile is viewed at the front side. Therefore, the color
changeable textile provides better visual variety.
[0038] Reference is made to FIG. 1 and FIG. 2, in which FIG. 1 is a
schematic front view of an embodiment of weaving the color
changeable textile of the invention, and FIG. 2 is a schematic side
view of the embodiment of weaving the color changeable textile of
the invention. The color changeable textile 100 is formed by
weaving two different yarns 200, 300. More particularly, the color,
the elongation, and the diameter of the yarn 200 are different from
that of the yarn 300. The yarns 200, 300 form a front yarn layer
and a rear yarn layer, and the front yarn layer and the rear yarn
layer construct the color changeable textile 100. In order to
describe clearly, the yarn 200 at the front in FIG. 1 (e.g. at the
left in FIG. 2) is called front yarn 200, and the yarn 300 at the
rear in FIG. 1 (e.g. at the right in FIG. 2) is called rear yarn
300, in the following embodiments.
[0039] In the color changeable textile 100, the front yarn 200
forms a plurality of front loops 210, and the front loops 210 are
connected to each other. The lateral front loops 210 (loops
arranged in a course) are formed by the same front yarn 200
(filling yarn), and the lateral front loops 210 are arranged side
by side. The vertical front loops 210 (loops arranged in a wale)
are connected to each other thereby forming the front yarn layer.
Each of the front loops 210 includes a needle loop 212, two legs
214, and a sinker loop 216, in which the legs 214 are the portions
where two courses of front loops 210 connected to each other, and
the needle loop 212 and the sinker loop 216 are connected to the
upper side and lower side of the legs 214 respectively. Namely, the
legs 214 at the upper course are connected by the needle loop 212
at the lower course, and the sinker loop 216 connects the adjacent
legs 214. In this embodiment, the front loops 210 are arranged in a
face loop manner, e.g., the legs 214 cover on the needle loop 216
at the front view.
[0040] The rear loops 310 are connected to each other thereby
forming a rear yarn layer. Each of the rear loops 310 includes a
needle loop 312, two legs 314, and a sinker loop 316 or a transfer
sinker loop 318. The rear loops 310 are substantially arranged side
by side in the course, and are connected to each other in the wale
thereby forming the rear yarn layer. The distinguishing features
between the front yarn layer and the rear yarn layer include: (1)
the rear loops 310 are arranged in a back loop manner, e.g., the
needle loop 312 covers the legs 314 at the front view; and (2) some
sinker loops 316 formed by the rear yarn 300 go toward the front
yarn layer and become the transfer sinker loops 318, in which the
transfer sinker loops 318 are coupled to the legs 214 for linking
the front and rear yarn layers. Thus, the front yarn layer formed
by the front yarn 200 and the rear yarn layer formed by the rear
yarn 300 are connected without any extra linking yarn.
[0041] With respect to the distinguishing feature (1), more
particularly, the front yarn layer formed by the front yarn 200 and
the rear yarn layer formed by the rear yarn 300 are corresponding
arranged front and rear. Meanwhile, the needle loops 212 of the
front loops 210 and the needle loops 312 of the rear loops 310 are
arranged face to face at the adjacent inner sides of the yarn
layers and are corresponding to each other.
[0042] With respect to the distinguishing feature (2), more
particularly, the front loops 210 and the rear loops 310 are
arranged in the same manner in course, but in a different manner in
wale. Some of the sinker loops 316 have the elongated loop length
and become transfer sinker loops 318. The transfer sinker loops 318
turn toward the front yarn layer and couple to the legs 214 of the
front loops 210, such that the front yarn layer and the rear yarn
layer are linked. In this embodiment, all of the sinker loops 316
of the rear loops 310 are utilized as the transfer sinker loops
318.
[0043] The transfer sinker loop 318 of the rear loop 310 is coupled
to the legs 214 of the front loop 210 in a predetermined manner.
For example, in this embodiment, the rear yarn 300 goes from the
rear yarn layer to the outside, which is facing away from the rear
yarn layer, of the front yarn layer via a left down side of the
sinker loop 216 of the corresponding front loop 210; the rear yarn
300 goes upward and crosses the leg 214 at the left side of the
needle loop 212 and returns the inner side, which is facing the
rear yarn layer, of the front yarn layer; the rear yarn 300 goes to
the right side of a leg at the right side of the needle loop 211
laterally; the rear yarn 300 further goes to the outside of the
front yarn layer at the right side of the leg 214 at the right side
of the needle loop 212; the rear yarn 300 goes downward and crosses
the sinker loop 216 and goes to the inner side of the front yarn
layer through the space between the legs 214 and returns the rear
yarn layer.
[0044] Since the front yarn layer and the rear yarn layer are
linked to each other by the rear yarn 300, an extra linking yarn
utilized in a conventional fabricating process is no longer
required in the present invention. More particularly, in the
conventional double jersey fabricating process, the front yarn
layer and the rear yarn layer are linked by a linking yarn, which
is different from the front and rear yarns. The loop length of the
linking yarn affects the property of the double jersey textile. For
example, if the loop length of the linking yarn is too long or is
elongated after being worn, the shape of the double jersey textile
becomes loose; if the loop length of the linking yarn is too short,
the stretch ability of the double jersey textile is restricted,
such that the wearer may feel uncomfortable when the wearer
exercises. However, the front yarn layer and the rear yarn layer
are linked to each other by the rear yarn 300 in the present
invention, therefore, the color changeable textile 100 is
integrated, and the problem of textile loosening or lacking
elasticity can be prevented.
[0045] In some embodiments, the front yarn 200 is a dark color
yarn, and the rear yarn 300 is a light color yarn with a color
lighter than the front yarn 200. The extension and the yarn
diameter of the front yarn 200 are larger than that of the rear
yarn 300. Therefore, when the color changeable textile 100 is
fabricated and at a natural state, the front loops 210 and the rear
loops 310 may gather because of the elongation of the front yarn
200 and the rear yarn 300. In some embodiments, the color of the
front yarn 200 and the rear yarn 300 can be selected according to
different design requirements. For example, the rear yarn 300 can
be a dark color yarn since the front yarn 200 is a light color
yarn. There is a color contrary between the front yarn 200 and the
rear yarn 300.
[0046] Reference is now made to FIG. 3 and FIG. 4. FIG. 3 is a
front view schematic diagram of an embodiment of the color
changeable textile before the color changeable textile is
stretched, and FIG. 4 is a front view schematic diagram of the
embodiment of the color changeable textile after the color
changeable textile is stretched. In FIG. 3, since the front yarn
200 has greater elongation and thicker yarn diameter, the gathering
front loops 210 have a fluffy look and provide shielding ability.
The portions where the rear yarn (not shown in FIG. 3) couples to
the front loops 210 are shielded by the gathering front loops 210,
thus the color changeable textile shows the color of the front yarn
200 at the front view before the color changeable textile is
stretched.
[0047] As shown in FIG. 4, when the color changeable textile is
stretched and deformed by an external force, the front yarn 200 and
the rear yarn (not shown) are also stretched and deformed. Since
the front yarn 200 has greater extension than the rear yarn 300,
the front yarn layer formed by the front yarn 200 also has good
extension. When the color changeable textile is stretched, the
front yarn 200 becomes thin and tight rather than fluffy.
Therefore, the gaps 215 are generated between the front loops 210.
The gaps 215 provide spaces for revealing the color of the rear
yarn. Namely, the color of the rear yarn is shown at the front
surface of the color changeable textile when the color changeable
textile is stretched. As a result, some portions at the front
surface of the color changeable textile show the color of the rear
yarn when the color changeable textile is stretched. Furthermore,
some of the front loops 210 are coupled by the transfer sinker
loops, thus the rear yarn coupled on the front loops 210 can be
prevented from shifting and can stay at the initial position.
Therefore, the transfer sinker loops formed by the rear yarn are
revealed at the gap 215 when the front loops 210 are deformed.
[0048] Reference is made back to FIG. 1. The front yarn 200 can be
a composite yarn in order to provide better stretch ability. For
example, the front yarn 200 is formed by blending a base yarn with
an elastic yarn. In some embodiments, the base yarn may be a
Polyethylene terephthalate (PET) and the elastic yarn may be a
spandex. The rear yarn 300 can be a PET yarn. Thus the elongation
of the front yarn 200 is better than that of the rear yarn 300.
More particularly, the ratio of a stretch ratio of the front yarn
layer formed by the front yarn 200 to a stretch ratio of the rear
yarn layer formed by the rear yarn 300 is in a range from about 1.1
to about 4. In some embodiments, the ratio of the stretch ratio of
the front yarn layer to the stretch ratio of the rear yarn layer is
in a range from about 1.1 to about 3, or in a range from about 1.1
to about 2. Accordingly, the yarn length of a rear loop 310 with a
transfer sinker loop 318 is not greater than 1.5 times of the
length of a corresponding front loop 210. By using the front yarn
200 with higher elongation, the rear yarn layer can be completely
covered by the front yarn layer when there is no external force
applied thereon. In some embodiments, the elastic yarn of the front
yarn 200 is about 0.5 wt % to 35 wt %. In some embodiments, the
elastic yarn of the front yarn 200 is about 2 wt % to 30 wt %,
preferably is about 2 wt % to 20 wt %.
[0049] Furthermore, the yarn diameter of the front yarn 200 is not
smaller than the yarn diameter of the rear yarn 300. In this
embodiment, the front yarn 200 is thicker than the rear yarn 300.
The color changeable textile 100 is formed by connecting the front
loops 210 and the rear loops 310. The front loops 210 have loop
gaps there between. If the size of the loop gaps is too big, the
color or pattern of the rear yarn layer is shown at the front yarn
layer via the loop gaps. Therefore, the size of the loop gaps can
be reduced by enlarging the diameter of the front yarn 200. Since
the loop gaps are filled by the front yarn 200 with larger
diameter, the front yarn layer can provide better visual blocking
ability, and the problem of grind through of a conventional double
jersey textile can be prevented.
[0050] As described above, by properly selecting the color, the
elongation, and the diameter of the front yarn 200 and the rear
yarn 300, and using the weaving process disclosed in the
embodiments, the color changeable textile 100 can show a color when
the color changeable textile 100 is not deformed, and the color
changeable textile 100 can show a different color or a different
pattern when the color changeable textile 100 is stretched and
deformed. The changing pattern of the color changeable textile 100
is discussed in FIG. 5 to FIG. 8.
[0051] FIG. 5 and FIG. 6 are a front exploded schematic view and a
side exploded schematic view of another embodiment of the color
changeable textile of the invention. The difference between this
embodiment and the previous embodiment includes that not every
sinker loop 316 is utilized as the transfer sinker loop 318, which
is coupled to the front loop 210. Namely, the rear loops 310 at
rear yarn layer couple to the front loops 120 in a skip stitch
manner. For example, every one of three wales of the rear loops 310
do not couple to the front loops 210, since the other two of three
wales of the rear loops 310 connect to the front loops 210. Details
of the connection between the front loops 210 and the rear loops
310 are discussed in FIG. 1 and FIG. 2.
[0052] In this embodiment, the color changeable textile 100 is
fabricated by the skip stitch manner. The front yarn 200 (see FIG.
5) has better elongation and thicker diameter, such that the front
yarn 200 covers the rear yarn (see FIG. 5), and the color
changeable textile 100 shows the color of the front yarn 200 when
there is no external force applied on the color changeable textile
100, as shown in FIG. 7.
[0053] However, when the color changeable textile 100 is stretched
and deformed, the portions of the rear loops coupled to the front
loops reveal the color of the rear yarn, and the portions which are
not coupled by the rear loops still show the color of the front
loops. Therefore, the color changeable textile 100 may show stripe
pattern, as shown in FIG. 8.
[0054] The pattern or the color revealed by the color changeable
textile 100 when the color changeable textile 100 is stretched can
be designed flexibly by changing the position and the ratio of the
rear yarn coupling on the front yarn.
[0055] FIG. 9 is a front schematic view of yet another embodiment
of the color changeable textile after being stretched. The present
embodiment is a variation based on the embodiment shown in FIG. 5.
For example, the rear loops are connected to the front loops in a
skip stitch manner at lateral direction (in wale), and the
connection portions are one-pitch switched in the vertical
direction (in course). As a result, the pattern revealed when the
color changeable textile 100 is stretched is a grid pattern formed
by the front yarn 200 and the rear yarn 300 in different
colors.
[0056] FIG. 10 and FIG. 11 are photographs of an embodiment of the
color changeable textile before and after being stretched. In FIG.
10, the color changeable textile is at a natural state, i.e. there
is no external force applied to the color changeable textile. The
color changeable textile has a front yarn layer and a rear yarn
layer, in which the front yarn layer is in a dark color (dark
blue), and the rear yarn layer is in a light color (pink). When the
color changeable textile is view at the front, the color changeable
textile shows the color of the font layer, i.e. the rear yarn layer
is covered by the front yarn layer and is not revealed. In FIG. 11,
the color changeable textile is stretched and deformed. As shown in
FIG. 11, at the portion of the stretched color changeable textile,
the color of the rear yarn is revealed; at the portion of the
non-stretched color changeable textile, the color changeable
textile remains the color of the front yarn. The color and the
pattern of the color changeable textile revealed when the color
changeable textile is stretched can be designed by controlling the
coupling portions of the rear loops and the front loops. More
particularly, the light color portions at the stretched color
changeable textile are the places where the rear loops couple to
the front loops, and the dark color portions at the stretched color
changeable textile are the places where the front loops are not
coupled by the rear loops. Designers can select the color of the
front yarn layer and the rear yarn layer. In most embodiments, a
color contrast is made between the front yarn layer and the rear
yarn layer.
[0057] The color changeable textile provided by the disclosure has
the front yarn layer and the rear yarn layer. When there is no
external force applied on the color changeable textile, the front
yarn layer covers the rear yarn layer, and thus the color of the
rear yarn is not revealed at the front yarn layer. When the color
changeable textile is stretched and deformed, at least the
stretched portion of the color changeable textile shows the color
of the rear yarn. Therefore, the color changeable textile can
provide more visual variations. Furthermore, the front yarn layer
and the rear yarn layer are linked by the rear yarn without using
an additional linking yarn. Therefore, the color changeable textile
of the disclosure can provide better elasticity and stretching
ability. The position and the ratio of the rear loops coupled to
the front loops can be controlled thereby designing the color
and/or pattern revealed by the color changeable textile when the
color changeable textile is stretched.
[0058] Although the present invention has been described in
considerable detail with reference to certain embodiments thereof,
other embodiments are possible. Therefore, the spirit and scope of
the appended claims should not be limited to the description of the
embodiments contained herein.
[0059] It will be apparent to those skilled in the art that various
modifications and variations can be made to the structure of the
present invention without departing from the scope or spirit of the
invention. In view of the foregoing, it is intended that the
present invention cover modifications and variations of this
invention provided they fall within the scope of the following
claims and their equivalents.
