DETAILED DESCRIPTION

[0017] In this specification, the term “content of yarn(s)” indicates that the content of a certain yarn in a fabric in which the total amount of yarns in the fabric is 100%.

[0018] In this specification, the term “offset rate” indicates that the length difference between two yarns taking a unit length of a composite yarn intermingled by two or more yarns. For example, taking a unit length of a composite yarn intermingled by a first yarn and a second yarn as a standard, when the length of the second yarn is 1.5 times of the length of the first yarn, the offset rate of the second yarn relative to the first yarn is 50%.

[0019] Please refer to FIG. 1. In some embodiments, a fabric may comprise an inner textile layer 10, an outer textile layer 20, and a middle textile layer 30. The middle textile layer 30 may be between the inner textile layer 10 and the outer textile layer 20.

[0020] In some embodiments, the inner textile layer 10 may comprise microfiber yarns and/ or elastic fiber yarns. In some embodiments, the inner textile layer 10 may be substantially consisting of the microfiber yarns and/ or the elastic fiber yarns. That is, the inner textile layer 10 may comprise the microfiber yarns and/ or the elastic fiber yarns as well as other yarns or other materials. In some embodiments, the inner textile layer 10 may comprise at least one selected from a group consisting of the microfiber yarns and the elastic fiber yarns.

[0021] In some embodiments, the size of the microfiber yarns may be below 150 deniers or below 30 deniers.

[0022] In some embodiments, the size of the elastic fiber yarns may be below 150 deniers or below 30 deniers. Further, in some embodiments, the material of the elastic fiber yarn may be polyurethane (PU), other alternatives, or any combinations of the foregoing. In other words, the material of the elastic fiber may be at least one selected from a group consisting of polyurethane (PU), other alternatives, or any combinations of the foregoing.

[0023] In some embodiments, the outer textile layer 20 may comprise a composite yarn 200. Please refer to FIG. 2. In some embodiments, the composite yarn 200 may comprise a first yarn 210 and a second yarn 220. The first yarn 210 may be thermo-fusible yarn. The second yarn 220 is winded and intermingled on the surface of the first yarn 210. Further, in some embodiments, the outer textile layer 20 may further comprise a plurality of elastic fiber yarns. That is, the outer textile layer 20 may be substantially consisting of the composite yarns 200 and the elastic fiber yarns. In some embodiments, the outer textile layers 20 may comprise the composite yarns 200 and the elastic fiber yarns as well as other yarns or other materials. In some other embodiments, the outer textile layer 20 may only have the composite yarns 200 and the elastic fiber yarns.

[0024] In some embodiments, the first yarn 210 (i.e., the thermo-fusible yarn) may have a core-spun yarn structure with a surface formed by a thermo-fusible fiber. Specifically, different kinds of fibers may be utilized as the core fiber and enclosed by the thermo-fusible fiber to form the thermo-fusible yarn with the core-spun yarn structure, and the melting point of the core fiber is higher than the melting point of the thermo-fusible fiber. In some embodiments, a polyester fiber may be enclosed by the thermo-fusible fiber to form the thermo-fusible yarn with the core-spun yarn structure. Further, in some embodiments, the material of the thermo-fusible fiber may be polypropylene, low temperature based polyethylene terephthalate (LPET), other alternatives, or any combinations of the foregoing. In other words, the material of the thermo-fusible fiber may be at least one selected from a group consisting of polypropylene, low temperature-based polyethylene terephthalate (LPET), other alternatives, or any combinations of the foregoing.

[0025] In some embodiments, the second yarn 220 may be uniformly winded on the surface of the first yarn 210. When the first yarn 210 is exposed under an environment having a temperature higher than the melting point of the thermo-fusible fiber of the first yarn 210 for thermal treatment, the thermo-fusible fiber on the surface of the first yarn 210 are softened or melted and firmly adhered with the second yarn 220 to form a single composite yarn 200. Here, as compared with a thermo-fusible yarn with the same thermal treatment, the composite yarn 200 still has the second yarn 220 on the surface of the composite yarn 200 after the thermal treatment. Therefore, the composite yarn 200 can provide a greater hand feeling as compared with the thermo-fusible yarn. Moreover, the fabric manufactured by the composite yarn 200 can provide a texture and a hand feeling similar to or same as a fabric without thermo-fusible fiber.

[0026] In some embodiments, taking a unit length of the composite yarn 200 as a standard, the offset rate of the second yarn 220 relative to the first yarn 210 is between 5% and 300%, for example, may be between 20% and 40%, or for example, may be 30%.

[0027] In some embodiments, the melting point of the first yarn 210 is lower than the melting point of the second yarn 220. For example, the melting point of the first yarn 210 may be between 160 Celsius and 190 Celsius, and the melting point of the second yarn 220 may be between 200 Celsius and 260 Celsius.

[0028] In some embodiments, the second yarn 220 may be normal polyethylene terephthalate (PET), other alternatives, or any combinations of the foregoing. In other words, the second yarn 220 may be at least one selected from a group consisting of normal polyethylene terephthalate (PET), other alternatives, or any combinations of the foregoing.

[0029] Please refer to FIG. 3. In some embodiments, the outer textile layer 20 may have a first weaving region 21 and a second weaving region 22. By adjusting the contents of the composite yarns 200 in the first weaving region 21 and/ or the contents of the composite yarns 200 in the second weaving region 22, the first weaving region 21 and the second weaving region 22 can provide different structural properties. For example, when the content of the composite yarn 200 in a weaving region of the fabric is higher, this weaving region can provide a stronger structural strength. Therefore, the weaving region can provide proper confining and supporting performances corresponding to a specific part of the user's body.

[0030] In some embodiments, when the content of the composite yarns 200 is 80%, it is indicated that 80% of the composite yarns 200 is on the outer textile layer 20 of the fabric.

[0031] In some embodiments, the content of the composite yarns 200 in the first weaving region 21 may be greater than the content of the composite yarns 200 in the second weaving region 22. For example, the content of the composite yarns 200 in the first weaving region 21 may be between 70% and 80%, and the content of the composite yarns 200 in the second weaving region 22 may be between 20% and 60%.

[0032] Please refer to FIG. 4. In some embodiments, the outer textile layer 20 may further comprise a third weaving region 23. Furthermore, the content of the composite yarns 200 in the third weaving region 23 is different from the content of the composite yarns 200 in the first weaving region 21, and the content of the composite yarns 200 in the third weaving region 23 is also different from the content of the composite yarns 200 in the second weaving region 22. For example, the content of the composite yarns 200 in the second weaving region 22 is less than the content of the composite yarns 200 in the first weaving region 21, and the content of the composite yarns 200 in the third weaving region 23 is less than the content of the composite yarns 200 in the second weaving region 22. For example, the content of the composite yarns 200 in the first weaving region 21 may be between 60% and 80%, the content of the composite yarns 200 in the second weaving region 22 may be between 20% and 40%, and the content of the composite yarns 200 in the third weaving region 23 may be from near 0% and 20%. In some embodiments, because the third weaving region 23 may mainly include elastic fiber yarns and a small number of composite yarns 200, the content of the composite yarns 200 in the third weaving region 23 may be near 0%.

[0033] Here, according to production requirements, the fabric according to one or some embodiments of the instant disclosure may be utilized for manufacturing clothes or uppers of shoes, for example, underwear, stretchy suits/pants, sportswear, socks, or uppers of sports shoes. Moreover, the positions of the first weaving region 21, the second weaving region 22, and/ or the third weaving region 23 may be arranged to correspond to different portions of a user's body for evaluating the suitable contents of the composite yarns 200 in each weaving region. Hence, the manufactured cloth can provide proper supporting performance, confining performance, fitting performance, so that when the user wears the cloth, the cloth not only provides a better body feeling but also protects user's muscle and reduces the possibility of sports injury.

[0034] Moreover, please refer to FIG. 5. In some embodiments, the composite yarn 200 may further comprise a third yarn 230. The third yarn 230 is an elastic yarn, and the first yarn 210, the second yarn 220, and the third yarn 230 are intermingled and cohered with each other. Under an environment having a temperature higher than the melting point of the thermo-fusible fiber on the surface of the first yarn 210, the first yarn 210 is softened or melted to provide adhesive property for adhering with the second yarn 220 and the third yarn 230. Moreover, the composite yarn 200 manufactured by the intermingled process has several intermingled nodes. The formation of the intermingled nodes allows the first yarn 210, the second yarn 220, and the third yarn 230 to be combined with each other closely. Therefore, the composite yarn 200 can provide a higher structural strength.

[0035] Similarly, as compared with a thermo-fusible yarn with the same thermal treatment, the composite yarn 200 still has the second yarn 220 and the third yarn 230 on the surface of the composite yarn 200 after the thermal treatment. Therefore, the composite yarn 200 can provide a greater hand feeling as compared with the thermo-fusible yarn. Moreover, the fabric manufactured by the composite yarn 200 having the second yarn 220 and the third yarn 230 can provide a texture and a hand feeling similar to or same as a fabric without thermo-fusible fiber.

[0036] In some embodiments, the third yarn 230 may be an elastic fiber yarn or other alternative yarns.

[0037] In some embodiments, the middle textile layer 30 may comprise polyester fiber yarns. In some embodiments, the middle textile layer 30 may be substantially consisting of polyester fiber yarns. That is, the middle textile layer 30 may comprise polyester fiber yarns and other negligible yarns or materials. In some embodiments, the middle textile layer 30 may only have polyester fiber yarns.

[0038] Furthermore, in some embodiments, the polyester fiber yarns of the middle textile layer 30 may be wave-shaped. Hence, the polyester fiber yarn may have a peak and a valley. The peak of each of the polyester fiber yarns is connected to the outer textile layer 20, and the valley of each of the polyester fiber yarns is connected to the inner textile layer 10.

[0039] In some embodiments, the wave-like polyester fiber yam of the middle textile layer 30 may be a monofilament fiber or a multifilament fiber.

[0040] For example, the fabric according to one or some embodiments of the instant disclosure may be utilized for manufacturing a brassiere. Please refer to FIG. 6. A brassiere comprises a cup body 40 having a lifting area 41 and an attaching area 42. The attaching area 42 is adjacent to the lifting area 41 and above the lifting area 41, as shown in FIG. 6. Please refer to FIG. 4 again. The first weaving region 21 and the second weaving region 22 of the fabric are at the lifting area 41, and the third weaving region 23 of the fabric is at the attaching area 42. For example, the content of the composite yams 200 in the first weaving region 21 is about 80%, the content of the composite yarns 200 in the second weaving region 22 is about 60%, and the content of the composite yarns 200 in the third weaving region 23 is about 20%. Moreover, the first weaving region 21, the second weaving region 22, and the third weaving region 23 are arranged in order, according to the contents of the composite yarns 200 in the first weaving region 21, the contents of the composite yarns 200 in the second weaving region 22, and the contents of the composite yams 200 in the third weaving region 23, respectively. Here, the contents of the composite yarns 200 is gradually decreased from the bottom to the top of the outer textile layer 20 and the structural strength of the outer textile layer 20 is also reduced from the bottom to the top. Therefore, when a user wears the brassiere, the lifting area 41 at the lower portion of the cup body 40 can allow the muscle at the outer sides of the user's breast to be focused inwardly and to lift up the breast, and the attaching area 42 can enclose and fit the user's breast smoothly to provide proper wearing experience.

[0041] Accordingly, the fabric according to one or some embodiments of the instant disclosure is suitable for manufacturing brassiere as well as stretchy suits/pants, sportswear, etc. By adjusting or managing the contents of the composite yarns in the weaving regions, the weaving regions can perform different functionalities (supporting performance, confining performance, lifting performance, and fitting performance), so that fabrics with different functionalities can be manufactured for specific portions of the user's body. Further, when the fabric according to one or some embodiments of the instant disclosure is applied for manufacturing sportswear, the use of the fabric in the sportswear facilitates the protection for the user's muscle and reduces the possibility of sports injury.
