Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile fabric technology, specifically to a lightweight and warm fabric. Background Technology
[0002] Developing fabrics for winter sports is more challenging than for summer sports. Athletes consider not only warmth but also comfort during exercise, requiring lightweight fabrics. Even in winter, prolonged exercise produces significant sweat. If this sweat isn't quickly wicked away from clothing, its evaporation will draw heat away from the body, leading to a damp and cold feeling. Therefore, textiles that quickly absorb and disperse sweat, dry rapidly, are lightweight, and provide warmth and comfort, keeping the skin dry, will be highly sought after by consumers and the market. Utility Model Content
[0003] The purpose of this invention is to provide a lightweight and warm fabric that is both lightweight and warm, as well as moisture-wicking and comfortable.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A lightweight and warm fabric is formed by interlacing warp yarns with a first weft yarn and a second weft yarn to form a double jacquard weave structure, which creates a zipper-like structure. The warp yarns interlaced with the first weft yarn form the front side of the fabric, and the warp yarns interlaced with the second weft yarn form the back side of the fabric. The warp yarns and the first weft yarn are made of nylon-spandex covered yarn, and the second weft yarn is made of wool core-spun yarn with a hollow core structure.
[0006] Preferably, the core yarn of the wool core-spun yarn is hollow nylon fiber, and the outer layer is wool fiber.
[0007] Preferably, the hollow structure of the hollow nylon fiber has a triangular cross-sectional shape.
[0008] Preferably, the metric count of the wool fiber is 60Nm-80Nm.
[0009] Preferably, the denier of the nylon-spandex coated yarn is 40D-70D.
[0010] Preferably, the core yarn denier of the nylon-spandex coated yarn is 15D-45D.
[0011] Preferably, the density of the warp yarn is 150T-180T, and the density of the first weft yarn and the second weft yarn is 150T-180T.
[0012] Preferably, the double jacquard weave is in a 10x12 cycle unit, with 10 warp yarns, 8 first weft yarns, and 4 second weft yarns. The first weft yarns are in rows 1, 2, 3, 4, 6, 8, 9, and 10, and the second weft yarns are in rows 5, 7, 11, and 12.
[0013] Preferably, the movement relationship of the first weft yarn in the first row and the ninth row on the 10 warp yarns is as follows: sink, float, sink, float, sink, float, sink, float, sink, float;
[0014] The movement relationship of the first weft yarn in the second row and the tenth row on the 10 warp yarns is as follows: float, sink, float, sink, float, sink, float, sink, sink;

[0021] Compared with the prior art, the present invention has the following beneficial effects:
[0022] This invention employs a double-layer jacquard weave structure, interwoven with the first and second weft yarns, to create a lightweight fabric with a zipper-like structure on both sides. The warp and first weft yarns are made of nylon-spandex coated yarn to ensure the fabric's elasticity, while the second weft yarn is made of wool core-spun yarn with a hollow core structure. The natural crimp of the wool fibers in the wool-coated yarn can trap air, and the hollow core structure forms a static air layer similar to down. Air is a poor conductor of heat, effectively insulating against cold air from the outside. At the same time, moisture is quickly wicked away to the front of the fabric for evaporation through capillary action, keeping the skin surface dry and comfortable, achieving excellent warmth retention without feeling stuffy. Attached Figure Description
[0023] Figure 1 This is a schematic diagram of the cross-section of the wool core-spun yarn of this utility model.
[0024] Figure 2 This is a schematic diagram of the double jacquard weave structure of this utility model. Detailed Implementation
[0025] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.
[0026] like Figures 1-2 As shown, this embodiment provides a lightweight and warm fabric, which uses a double weft jacquard weave structure formed by interlacing warp yarns with the first weft yarn and the second weft yarn to form an attractive zipper structure. The front side of the fabric is formed by interlacing warp yarns with the first weft yarn, and the back side of the fabric is formed by interlacing warp yarns with the second weft yarn. The warp density is 150T-180T, and the weft density is 150T-180T.
[0027] In this embodiment, the warp yarn is specifically a nylon-spandex covered yarn with a denier of 40D-70D, with spandex as the core yarn and PA66DTY fiber as the outer layer. Specifically, the spandex used is spandex with a denier of 15D-45D. During the process of covering this range of spandex with PA66DTY fiber, after a certain tension stretching, a covered yarn that is neither exposed nor lacks elasticity can be obtained. This allows the fabric formed by the interlacing of the warp yarn and the first weft yarn of the same yarn to possess lightweight, elasticity, and abrasion resistance on the front side, while also having a good texture. The first weft yarn uses the same yarn as the warp yarn.
[0028] In this embodiment, the second weft yarn is specifically a wool core-spun yarn 20, with the core yarn being hollow nylon fiber and the outer layer being wool fiber. Specifically, the wool fiber has a metric count of 60Nm-80Nm, and the hollow structure of the nylon fiber preferably has a triangular cross-section, such as... Figure 1 As shown. The second weft yarn is interwoven with the warp yarn and embedded on the back of the fabric, significantly improving its warmth. This is thanks to the hollow structure of the hollow nylon fibers, which creates a static air layer similar to down. Air is a poor conductor of heat, effectively insulating against cold air and providing excellent warmth. Wool fibers, wrapped around the outer layer of the hollow nylon fibers, offer exceptional skin-friendliness and comfort. The natural crimp of wool traps air, providing excellent warmth. Simultaneously, wool fibers have excellent moisture absorption, generating heat during moisture absorption. The internal hollow nylon fibers, through capillary action, quickly conduct moisture to the front of the fabric for evaporation, keeping the skin dry and comfortable, achieving excellent warmth without feeling stuffy. Wool core-spun yarn 20 is more wear-resistant and less prone to pilling than pure wool yarn, greatly maintaining the fabric's aesthetics and durability.
[0029] In this embodiment, the blending ratio of wool fibers to hollow nylon fibers in the wool core-spun yarn 20 is controlled within the range of 35 / 65 to 70 / 30. Within this specific ratio range, the resulting fabric perfectly combines the unique comfort and excellent warmth retention of wool fibers with the superior elasticity and abrasion resistance of nylon. By organically combining wool fibers and hollow nylon fibers, not only is the anti-pilling performance of the fabric significantly improved, but its overall performance is also further enhanced. Specifically, the hollow nylon fibers act as a skeleton, providing a solid support structure for the fabric, while the wool fibers, as the outer covering and restraining layer, not only effectively maintain the unique drape of wool fibers but also ensure the fabric's excellent performance in terms of wrinkle resistance and aesthetics.
[0030] This embodiment uses, as follows: Figure 2 The weave is performed according to the diagram shown. The longitudinal yarns are warp yarns, i.e., 1, 2, 3… in the diagram refer to the warp yarns. This means that the warp direction of this double jacquard weave consists of 10 warp yarns forming one cycle. In the transverse yarns, A represents the first weft yarn, and B represents the second weft yarn. A total of 12 first and second weft yarns form one cycle. The warp yarns are woven with 8 first weft yarns and 4 second weft yarns according to… Figure 2 The weave shown can create a zipper-like structure with a double-layer effect.
[0031] The first weft yarns are in rows 1, 2, 3, 4, 6, 8, 9, and 10: the movement relationship of the first weft yarns in the first and ninth rows on the 10 warp yarns is sinking, floating, sinking, floating, sinking, floating, sinking, floating, sinking, floating; the movement relationship of the first weft yarns in the second and tenth rows on the 10 warp yarns is floating, sinking, floating, sinking, floating, sinking, floating, sinking, floating, sinking; the movement relationship of the first weft yarns in the third and sixth rows on the 10 warp yarns is floating, sinking, sinking, floating, sinking, floating, sinking, floating, sinking, floating; the movement relationship of the first weft yarns in the fourth and eighth rows on the 10 warp yarns is sinking, floating, floating, sinking, floating, sinking, floating, sinking, floating, sinking.
[0032] The second weft yarn is located in rows 5, 7, 11, and 12: the movement relationship of the second weft yarn in the fifth row on the 10 warp yarns is, in order, floating, sinking, floating, floating, floating, floating, floating, floating, sinking, floating; the movement relationship of the second weft yarn in the seventh row on the 10 warp yarns is, in order, sinking, floating, floating, sinking, floating, floating, floating, floating, floating, floating; the movement relationship of the second weft yarn in the eleventh row on the 10 warp yarns is, in order, sinking, floating, sinking, floating, floating, floating, floating, floating, floating; the movement relationship of the second weft yarn in the twelfth row on the 10 warp yarns is, in order, floating, sinking, floating, floating, floating, floating, floating, floating.
[0033] Note that the above description of the movement relationship between the first weft yarn and the warp yarn is based on the position on the front side of the fabric, while the above description of the movement relationship between the second weft yarn and the warp yarn is based on the position on the back side of the fabric.
[0034] In this embodiment, the fabric's back is napped to create a fluffy, soft fleece, significantly increasing the contact area with the skin, resulting in a softer, smoother feel and excellent warmth retention. In summary, the fabric in this embodiment constructs a highly efficient system that integrates heat retention and moisture wicking, achieving a balance between lightweight and high performance, as well as durability and comfort.
