Description

Technical Field

[0001] This utility model relates to a cashmere denim fabric, belonging to the textile field. Background Technology

[0002] Traditional denim fabric is made by interlacing pure cotton warp yarns dyed with indigo dye with natural white pure cotton weft yarns. For over a century, it has remained a staple in the fashion world, holding an irreplaceable position in the clothing market. With socio-economic development and improved living standards, people's pursuit of clothing has expanded beyond design to include comfort and functionality. People's clothing preferences vary depending on the environment. For example, in cold weather, people need comfortable and warm clothing to protect themselves from the cold.

[0003] In existing technologies, some technicians use functional yarns such as far-infrared heating and moisture-absorbing heat to weave fabrics, but the warmth retention effect is weak and can never reach the warmth of wool sweaters, and it will cause the skin to become abnormally dry.

[0004] Some technicians also use thermal insulation materials to coat fabrics, giving them a warming function. However, many of these materials are irritating to the skin and can affect health to some extent. Due to the special nature of denim clothing, it needs to undergo washing processes (enzyme bleaching, chlorine bleaching, oxygen bleaching, manganese bleaching, etc.) after garment making, which can damage the coating effect.

[0005] Cashmere fibers consist of a scale layer and a cortex layer. They are lightweight, have a smooth and supple feel, and offer better warmth retention than other animal fibers, providing superior protection against the cold. However, wearing large areas of cashmere directly against the skin can cause itching. Therefore, how to incorporate cashmere into denim fabrics remains a technical challenge to be solved in this field. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a cashmere denim fabric that can reduce the direct contact between cashmere fibers and the skin.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] This application provides a cashmere denim fabric comprising interwoven warp and weft yarns. The warp yarns include a first warp yarn and a second warp yarn, and the weft yarns include a first weft yarn and a second weft yarn. The first warp yarn and the first weft yarn interweave to form an upper layer, and the second warp yarn and the second weft yarn interweave to form a lower layer. The second weft yarn is thicker than the first weft yarn, and the first weft yarn is made of elastic core-spun yarn and cashmere yarn twisted together.

[0009] The cashmere denim fabric provided in this application features cashmere yarn in the upper layer, with the first weft yarn being finer than the second weft yarn. The coarser second weft yarn in the lower layer effectively conceals the first weft yarn on the bottom surface, thus reducing the chance of the fabric bottom surface contacting the cashmere yarn. The elastic core-spun yarn and cashmere yarn are twisted together, compensating for the insufficient strength of the cashmere yarn. Moreover, from the bottom surface of the upper layer, it is equivalent to the elastic core-spun yarn and cashmere yarn alternating, further reducing the chance of the fabric bottom surface contacting the cashmere yarn. The elastic core-spun yarn gives the first weft yarn elasticity, thereby tightening the upper layer, while the lower layer yarn is more easily stretched, further reducing the chance of the fabric bottom surface contacting the cashmere yarn.

[0010] Furthermore, the number of weft stitches formed by the first weft yarn in the upper layer is half the number of weft stitches formed by the second weft yarn in the lower layer.

[0011] Furthermore, the elastic elongation of the first weft yarn is greater than that of the second weft yarn, which is beneficial to make the lower layer more relaxed than the upper layer, and the weft yarn of the lower layer is the second weft yarn, which makes it easier for the lower layer to come into contact with the skin.

[0012] Furthermore, the first warp yarn and the first weft yarn are interwoven in a three-up-one-down twill pattern to form the upper layer, while the first warp yarn and the second weft yarn do not interweave.

[0013] Furthermore, the first warp yarn is thicker than the second warp yarn, so that the first warp yarn can cover the lower layer on the front side of the fabric, preventing the lower layer from affecting the texture of the upper layer.

[0014] Furthermore, the second warp yarn and the first weft yarn are interwoven in a plain weave, which makes the fabric structure stable and helps the fabric bottom surface to still have good tear resistance after being brushed and piled.

[0015] Furthermore, the yarn count of the cashmere yarn is 25S~60S.

[0016] Furthermore, the elastic core-spun yarn comprises a spandex core and filaments wound around the surface of the spandex core. Cashmere yarn has weak inter-fiber cohesion and low yarn strength; by using this structure, the elastic core-spun yarn is twisted with cashmere yarn, which can improve the strength of the first weft yarn.

[0017] Furthermore, the denier of the filament is 40D~100D, which allows the filament to maintain high strength, making the fabric stronger and more durable, without being too coarse and heavy, so that the elastic core-spun yarn can provide good elasticity and abrasion resistance for the first weft yarn.

[0018] Furthermore, the bottom surface of the lower layer is provided with a fleece layer, which can significantly enhance the warmth of the fabric. The fleece layer can effectively trap air, thereby improving the fabric's insulation effect, especially providing better protection in cold environments.

[0019] The beneficial effects of this utility model are as follows: This utility model designs cashmere yarn in the upper layer, and makes the first weft yarn finer than the second weft yarn, while the coarser second weft yarn in the lower layer can better cover the first weft yarn on the bottom surface; the elastic core-spun yarn and cashmere yarn are twisted together, which makes up for the problem of insufficient strength of cashmere yarn, and from the bottom surface of the upper layer, it is equivalent to the elastic core-spun yarn and cashmere yarn appearing alternately; moreover, the elastic core-spun yarn makes the first weft yarn elastic and tightens the upper layer, making the lower layer yarn easier to stretch, which helps to reduce the chance of the bottom surface of the fabric coming into contact with the cashmere yarn, so as to give full play to the warmth retention of cashmere yarn and avoid the itching sensation caused by large areas of cashmere contacting the skin.

[0020] Other features and advantages of this application will be set forth in the following description and will be apparent in part from the description or may be learned by practicing the application. The objectives and other advantages of this application may be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] The following disclosure provides many different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0028] Unless otherwise specified, all technical and scientific terms used herein have the standard meaning in the field to which the claimed subject matter pertains. Where multiple definitions exist for a term, the definition herein shall prevail.

[0029] Reference Figures 1 to 3 A cashmere denim fabric comprising interwoven warp and weft yarns, the warp yarns comprising a first warp and a second warp, the weft yarns comprising a first weft and a second weft, the first warp and the first weft interwoven to form an upper layer 1, the second warp and the second weft interwoven to form a lower layer 2, the second weft yarn being thicker than the first weft yarn, and the first weft yarn being made of elastic core-spun yarn 9 and cashmere yarn 8 twisted together.

[0030] This design, while maintaining the fabric's warmth, features a finer first weft yarn and a coarser second weft yarn, effectively concealing the cashmere yarn 8 on the fabric's underside. This structure reduces the chance of the cashmere yarn directly contacting the skin, minimizing discomfort such as itching that might result from large-area contact with the skin. The combination of the elastic core-spun yarn 9 and the cashmere yarn 8 effectively strengthens the first weft yarn, making the fabric more durable.

[0031] Preferably, the number of weft points formed by the first weft yarn in the upper layer 1 is half the number of weft points formed by the second weft yarn in the lower layer 2 (viewed from the front of the process). This helps to reduce the chance of the surface of the upper layer 1 coming into contact with the cashmere yarn, so that neither side of the fabric comes into large contact with cashmere. Moreover, it allows the bottom surface of the upper layer 1 to have more weft floats (viewed from the reverse side of the upper layer), which is equivalent to placing the first weft yarn as close as possible to the middle of the fabric (closer to the top surface of the lower layer), thus providing warmth in the middle of the fabric.

[0032] More preferably, the elastic elongation of the first weft yarn is greater than that of the second weft yarn. The upper layer 1 is tighter than the lower layer 2, which reduces the amount of the first weft yarn that can be contacted on the fabric's surface. The lower layer 2 is looser than the upper layer 1, allowing the lower yarns to stretch more easily, increasing the chance of contact with the second warp and second weft yarns on the fabric's underside and reducing the chance of contact with the first weft yarn. Furthermore, the tighter structure of the upper layer 1 gives the fabric a certain degree of windproof effect.

[0033] In some embodiments, a pile layer 3 is provided on the bottom surface of the lower layer 2. This pile layer 3 is obtained by a napping process. Since the bottom surface of the fabric is more likely to touch the second warp and second weft yarns and less likely to touch the first weft yarn, the pile formed by napping is mainly provided by the fibers of the second warp and second weft yarns, and less by the first weft yarn, which helps to reduce the itching sensation of the fabric.

[0034] To meet the elasticity requirements of the first weft yarn, refer to Figure 3 The elastic core-spun yarn 9 comprises a spandex core 91 and filaments 92 wound around the surface of the spandex core 91. The spandex core 91 provides excellent elasticity, giving the fabric good stretchability and increasing wearing comfort and freedom of movement. The filaments 92, covering the surface of the spandex core 91, enhance the strength of the yarn. Cashmere yarn has weak cohesion between fibers and low yarn strength, making it prone to breakage when woven directly. Applying the first weft structure of this embodiment makes it easier to weave. Preferably, the denier of the filaments 92 is 40D~100D. The filaments (defaulting to synthetic fibers) have high strength; winding them around the spandex core to form plied yarn provides a certain degree of elasticity and strength, effectively solving the problem of easy breakage during cashmere yarn weaving. Meanwhile, the cashmere yarn 8 has a yarn count of 25S~60S, which can ensure the softness and warmth of the cashmere yarn, as well as ensure that the fabric has sufficient strength, durability and service life, and adapt to the subsequent possible brushing process.

[0035] As one example of weaving, please refer to Figure 4 , Figure 4 In the diagram, Arabic numerals represent the first warp yarn number, Roman numerals represent the second warp yarn number, uppercase English letters represent the second weft yarn number, and lowercase English letters represent the first weft yarn number. As a convention in this field, shaded grids represent warp weft points (viewed from the front of the process), and unshaded grids represent weft weft points (viewed from the front of the process).

[0036] In this embodiment, the first warp yarn and the first weft yarn are interwoven in a three-up-one-down twill weave to form the upper layer 1. The first warp yarn and the second weft yarn do not interweave, giving the upper layer 1 the appearance of traditional denim fabric and preventing the second weft yarn from affecting the texture of the upper layer 1. Simultaneously, the second warp yarn and the first weft yarn are interwoven in a plain weave, and the second warp yarn and the second weft yarn are interwoven in a plain weave. This plain weave structure increases the stability of the fabric and also helps to enhance its strength, reducing fabric deformation due to washing or use.

[0037] Preferably, the first warp yarn is thicker than the second warp yarn. The thicker first warp yarn provides stronger support, helping to enhance the stability of the fabric and preventing deformation or damage during use. Because the first warp yarn is thicker, it not only helps improve the fabric's abrasion resistance and tensile strength but also reflects the traditional twill weave effect of denim fabric.

[0038] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0039] The above description is the preferred embodiment of this utility model.
