AI Technical Summary
Traditional denim fabrics are thick and uncomfortable when worn in summer, and staple fibers are prone to bleaching and pilling during use, which affects the wearing experience.
The composite yarn is formed by blending the first fiber and the second fiber, and the contact method of the yarn is optimized, so that its surface is tangent or point-to-side tangent connection is made, and the gaps between the yarns are increased to better absorb and diffuse sweat.
By optimizing the contact method of composite yarns, there are more gaps between the yarns inside the fabric. When sweat comes into contact with the yarn surface, it can be quickly absorbed and diffused to the outer surface of the fabric and evaporate quickly, thus making the human body feel dry and cool.

The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0034] like Figure 1 As shown, the utility model provides a composite yarn 10, which is formed by blending a first fiber 110 and a second fiber 120, and the surface of the first fiber 110 is tangent to the surface of the second fiber 120;
[0035] The cross-sectional shape of the first fiber 110 is polygonal, and the cross-sectional shape of the second fiber 120 is circular.
[0036] The textile specification of the composite yarn 10 is 8-40 Ne.
[0037] Specifically, the textile specifications of the composite yarn 10 can be, but are not limited to, 8 Ne, 10 Ne, 12 Ne, 14 Ne, 16 Ne, 18 Ne, 20 Ne, 21 Ne, 22 Ne, 23 Ne, 23.5 Ne, 24 Ne, 25 Ne, 26 Ne, 28 Ne, 30 Ne, 32 Ne, 34 Ne, 36 Ne, 38 Ne or 40 Ne.
[0038] The utility model optimizes the contact mode in the composite yarn 10 so that the surfaces of the first fiber 110 and the second fiber 120 are connected face-to-face or point-to-face, and more gaps exist between the yarns inside the fabric. When sweat contacts the yarn surface, it can be quickly absorbed and diffused to the outer surface of the fabric and evaporated quickly, thereby making the human body feel dry and cool.
[0039] In a specific example, the cross-sectional shape of the first fiber 110 is a cross, a triangle, a Y-shape, a pentagon or a pentagon. It is understandable that the cross-sectional shape of the first fiber 110 is preferably a cross, having a plurality of surfaces that can be in tangential contact with the second fiber 120.
[0040] In a specific example, the textile specification of the first fiber 110 is 40D-105D, and the textile specification of the second fiber 120 is 100D-225D.
[0041] Further, the number of strands per bundle of the first fiber 110 is 40-144, which can be expressed as 40F-144F; the number of strands per bundle of the second fiber 120 is 100-225, which can be expressed as 100F-225F. Specifically, the denier (D) in the above textile specifications is defined as the weight in grams of a 9000-meter-long fiber at a standard regain, and the imperial count, that is, the English count (S), is defined as one English count for each pound (0.4536kg) of fiber or yarn length of 840 yards at a standard regain. Therefore, the conversion relationship between English count (S) and denier (D) is denier × English count = 5315 (D×S=5315). F represents the number of strands per bundle of silk. Taking 75D / 68F as an example, it means that every 9000 meters is 75 grams and is composed of 68 strands of single silk.
[0042] In a specific example, the mass ratio of the first fiber 110 to the second fiber 120 in the composite yarn 10 is (30-50): (50-70). It can be understood that the mass ratio of the first fiber 110 to the second fiber 120 can be, but is not limited to, 30:70, 40:60 or 50:50.
[0043] It can be understood that the above-mentioned limitation on the mass ratio of the first fibers 110 to the second fibers 120 is actually a limitation on the number of fibers.
[0044] In a specific example, the first fiber 110 and the second fiber 120 each independently include one of cotton fiber, nylon fiber, acetate fiber, spandex fiber and polyester fiber.
[0045] In a specific example, the first fiber 110 and the second fiber 120 are each independently a white fiber or a colored fiber.
[0046] The utility model also provides a denim fabric, which is woven by warp yarns and weft yarns;
[0047] At least one of the warp yarns and the weft yarns is the composite yarn 10 mentioned above.
[0048] In a specific example, the warp yarn is a yarn formed by a single fiber selected from the group consisting of cotton fiber, viscose fiber, linen fiber, lyocell fiber, and Tencel fiber, or a yarn formed by a blend of multiple fibers; and the weft yarn is a yarn formed by a blend of two or more fibers selected from the group consisting of cotton fiber, nylon fiber, acetate fiber, spandex fiber, and polyester fiber.
[0049] Furthermore, the warp yarn is lyocell fiber or a blend of cotton fiber and lyocell fiber.
[0050] In a specific example, the yarn weaving specification of the warp yarn is 8-40. Specifically, the yarn weaving specification of the warp yarn can be, but is not limited to, 8, 12, 16, 20, 24, 28, 32, 36, 38 or 40.
[0051] In a specific example, the density of the warp yarn is 60 to 160 strands / inch. Preferably, the density of the warp yarn is 90 to 134 strands / inch. Specifically, the density of the warp yarn can be, but is not limited to, 90 strands / inch, 94 strands / inch, 98 strands / inch, 102 strands / inch, 106 strands / inch, 110 strands / inch, 114 strands / inch, 118 strands / inch, 122 strands / inch, 126 strands / inch, 130 strands / inch, 132 strands / inch or 134 strands / inch.
[0052] In a specific example, the warp yarn is a natural yarn or a dyed yarn dyed with indigo dye or sulfur dye.
[0053] Furthermore, the weft yarn is a blended yarn of nylon fiber and acetate fiber.
[0054] In a specific example, the yarn weaving specification of the weft yarn is 8-32. Specifically, the yarn weaving specification of the weft yarn can be, but is not limited to, 8, 12, 16, 20, 24, 28, 32, 36, 38 or 40.
[0055] In a specific example, the density of the weft yarn is 40 to 80 strands / inch. Preferably, the density of the weft yarn is 60 to 70 strands / inch, and specifically, the density of the weft yarn can be, but is not limited to, 60 strands / inch, 62 strands / inch, 64 strands / inch, 66 strands / inch, 68 strands / inch or 70 strands / inch.
[0056] In a specific example, the weft yarn is a white yarn or a colored yarn.
[0057] In a specific example, the fabric is one or more of plain weave, twill weave, double plain weave and jacquard weave.
[0058] Furthermore, the utility model also provides a garment, at least part of which comprises the above-mentioned denim fabric.
