A comfortable cotton tencel jean fabric

Abstract

This utility model discloses a comfortable cotton-Tencel denim fabric, belonging to the textile field. It comprises interwoven weft yarns and pure cotton warp yarns. The weft yarns consist of two systems: honeycomb polyester weft yarn and a second weft yarn. The second weft yarn includes parallel pure cotton weft yarns and Tencel weft yarns. The pure cotton warp yarns and honeycomb polyester weft yarns interweave to form the upper layer, and the pure cotton warp yarns and the second weft yarns interweave to form the lower layer. The number of warp stitches on the upper layer's fabric face is greater than the number of weft stitches. This fabric allows cotton and Tencel fibers to directly contact the skin, providing excellent moisture absorption and skin-friendliness. The honeycomb polyester weft yarns are mostly located between the upper pure cotton warp yarns and the lower layer, thus quickly transferring moisture absorbed by the lower layer to the upper pure cotton warp yarns. Combined with the lower layer's weave, this allows for rapid absorption of moisture from the skin, which is then transferred to the fabric face and spread out, accelerating moisture evaporation and reducing sweat accumulation on the fabric. Simultaneously, the fabric exhibits low shrinkage and good dimensional stability.

Description

Technical Field

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

[0002] With societal development, people's pursuit of denim clothing is increasing, going beyond just style design to prioritize comfort and functionality. As a result, traditional pure cotton denim fabrics are gradually failing to meet market demands. In the research and development of denim fabrics, new types of regenerated cellulose fibers, such as Tencel, viscose, Modal, and bamboo fiber, are commonly used. These fibers have excellent moisture absorption, resulting in fabrics that are comfortable to the touch, have good drape, and are biodegradable. For example, one or more of these regenerated cellulose fibers can be used to process yarns, making the resulting denim fabric comfortable to the touch and natural to wear. However, due to the high moisture absorption of these regenerated cellulose fibers, the resulting fabrics have a high and unstable shrinkage rate, making it difficult to control dimensional stability. After denim garments are made, they undergo special washing processes for aging (enzyme bleaching, chlorine bleaching, oxygen bleaching, manganese bleaching, etc.), which affects the yarn structure, further reducing the garment's shape retention. Denim garments using these regenerated cellulose fibers are prone to wrinkling during daily wear. On the other hand, although fabrics made from regenerated cellulose fibers have good moisture absorption and can absorb a lot of sweat from the surface of human skin, their ability to transfer moisture is weak. Sweat cannot spread and diffuse on the fabric surface in time, and a lot of sweat accumulates on the fabric, causing stuffiness and stickiness, resulting in discomfort when wearing it. Therefore, the existing technology needs to be improved. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a comfortable cotton Tencel denim fabric with good dimensional stability and both moisture absorption and moisture wicking properties.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A comfortable cotton-Tencel denim fabric with a double weft structure, comprising interwoven weft yarns and pure cotton warp yarns. The weft yarns include two systems of yarns: honeycomb polyester weft yarn and a second weft yarn. The second weft yarn includes parallel pure cotton weft yarns and Tencel weft yarns. The pure cotton warp yarns and the honeycomb polyester weft yarns interweave to form the upper layer, and the pure cotton warp yarns and the second weft yarns interweave to form the lower layer. The upper layer has more warp weft points than weft weft points on the front side.

[0006] The comfortable cotton-Tencel denim fabric provided in this application uses pure cotton warp yarns, pure cotton weft yarns, and Tencel weft yarns to form the lower layer, which is for direct contact with the skin and has good moisture absorption and skin-friendliness. The pure cotton warp yarns and honeycomb polyester are interwoven to form the upper layer, and the upper layer has more warp points than weft points, so that the honeycomb polyester weft yarn is roughly located in the middle between the pure cotton warp yarns of the upper layer and the lower layer. Therefore, the honeycomb polyester weft yarn can use its own excellent moisture-wicking ability to quickly transfer the moisture absorbed by the lower layer to the pure cotton warp yarns of the upper layer, so that the moisture is quickly absorbed from the skin and then transferred to the front of the fabric to spread out, accelerating the evaporation of moisture and reducing the accumulation of sweat on the fabric. The honeycomb polyester weft yarn participates in the formation of the upper layer, and the pure cotton warp yarns participate in the formation of both the upper and lower layers. This allows the upper layer yarns, which are more difficult to deform, to exert a restraining effect on the lower layer. At the same time, the pure cotton weft yarns in the lower layer, which are parallel to the Tencel weft yarns, use the pure cotton warp yarns to restrict the deformation of the Tencel weft yarns, so that the fabric has a low shrinkage rate and good dimensional stability.

[0007] Furthermore, the twist coefficient of the Tencel weft yarn is 4% to 6% higher than that of the pure cotton weft yarn, which helps to eliminate the dimensional change problem caused by the stronger moisture absorption of Tencel fiber compared to cotton fiber, and can better solve the problem of poor shape retention of fabrics made of regenerated cellulose fiber.

[0008] Furthermore, the twist direction of the Tencel weft yarn is opposite to that of the pure cotton weft yarn, which helps to reduce the problem of fabric deformation caused by internal fiber stress.

[0009] Furthermore, the ratio of the Tencel weft yarn to the pure cotton weft yarn is 1:1.

[0010] Furthermore, in the lower layer, the pure cotton weft yarn is located between adjacent Tencel weft yarns, and this arrangement enhances the stability of the lower layer structure.

[0011] Furthermore, the Tencel weft yarn and the pure cotton weft yarn have the same count, which helps to make the fabric look smoother and more even, and helps to coordinate the moisture absorption capacity of the Tencel weft yarn and the pure cotton weft yarn.

[0012] Furthermore, the second weft yarn is thicker than the honeycomb polyester weft yarn.

[0013] Furthermore, the upper layer has a twill weave structure.

[0014] Furthermore, the upper layer has a three-up-one-down diagonal pattern.

[0015] Furthermore, the underlying weave is plain weave, twill weave, or satin weave.

[0016] The beneficial effects of this invention are as follows: The comfortable cotton-Tencel denim fabric of this invention has cotton and Tencel fibers in direct contact with the skin, providing excellent moisture absorption and skin-friendliness. Most of the honeycomb polyester weft yarns are located between the upper pure cotton warp yarns and the lower layer, thus enabling rapid transfer of moisture absorbed by the lower layer to the upper pure cotton warp yarns. Combined with the lower layer structure, this allows for rapid absorption of moisture from the skin, which is then transferred to the front of the fabric, accelerating moisture evaporation and reducing sweat accumulation on the fabric. The upper yarns exert a restraining effect on the lower layer, while the lower layer, with its pure cotton weft yarns using the pure cotton warp yarns to limit the deformation of the Tencel weft yarns, results in a fabric with a low shrinkage rate and good dimensional stability.

[0017] 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. Attached Figure Description

[0019] 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.

[0020] 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.

[0021] Reference Figure 1 This application provides a comfortable cotton-Tencel denim fabric with a double weft structure, comprising interwoven weft yarns and pure cotton warp yarns. The weft yarns include two systems of yarns, namely honeycomb polyester weft yarn and a second weft yarn. The second weft yarn includes parallel pure cotton weft yarns and Tencel weft yarns. The pure cotton warp yarns and honeycomb polyester weft yarns interweave to form the upper layer, and the pure cotton warp yarns and the second weft yarns interweave to form the lower layer. The number of warp weft points on the front side of the upper layer is greater than the number of weft weft points.

[0022] in, Figure 1 According to textile industry practice, filled squares represent warp points on the front side of the process, while unfilled squares represent weft points on the front side. Meanwhile, Figure 1 The warp yarn number is represented by Arabic numerals, the first weft yarn by lowercase letters, and the second weft yarn by uppercase letters. For example, column 2, row B indicates the interlacing point of the pure cotton warp yarn and the honeycomb polyester weft yarn, with the honeycomb polyester weft yarn overlapping the pure cotton warp yarn.

[0023] In the illustrated embodiment, the upper layer has a three-up-one-down twill weave, which showcases the unique texture of denim fabric, while the lower layer has a one-up-one-down twill weave, which provides better structural stability.

[0024] Generally, fabrics made from regenerated cellulose fibers have good moisture absorption but poor moisture transfer capacity. Sweat cannot spread and diffuse on the fabric surface in time, easily accumulating in large amounts on the fabric. Furthermore, due to the surface tension of water, the fabric clings tightly to the skin, causing discomfort when worn. In addition, fabrics made from regenerated cellulose fibers have poor dimensional stability.

[0025] In this embodiment, a lower layer is formed by interlacing pure cotton warp yarns, pure cotton weft yarns, and Tencel weft yarns. This layer is for direct contact with the skin and has good moisture absorption and skin-friendliness. The upper layer is formed by interlacing pure cotton warp yarns and honeycomb polyester, with more warp points than weft points. This allows the honeycomb polyester weft yarn to be located roughly in the middle between the upper pure cotton warp yarns and the lower layer. Therefore, the honeycomb polyester weft yarn can utilize its excellent moisture-wicking ability to quickly transfer the moisture absorbed by the lower layer to the upper pure cotton warp yarns. This allows the moisture to be quickly absorbed by the skin and then transferred to the front of the fabric to spread out, accelerating moisture evaporation, reducing sweat accumulation on the fabric, preventing the fabric from sticking to the skin, eliminating stuffiness, and making it more comfortable.

[0026] Honeycomb polyester weft yarns participate in the formation of the upper layer, while pure cotton warp yarns participate in both the upper and lower layers. This allows the upper layer yarns, which are more difficult to deform, to exert a restraining effect on the lower layer. At the same time, the lower layer, with pure cotton weft yarns running parallel to Tencel weft yarns, uses pure cotton warp yarns to limit the deformation of Tencel weft yarns, resulting in a fabric with a low shrinkage rate and good dimensional stability.

[0027] In some embodiments, the twist coefficient of Tencel weft yarn is 4% to 6% higher than that of pure cotton weft yarn.

[0028] Tencel fibers are highly hygroscopic. If the twist coefficient of the Tencel weft yarn is the same as that of pure cotton weft yarn, the difference in fiber expansion and contraction after moisture absorption may cause changes in fabric dimensions. The higher twist coefficient of the Tencel weft yarn makes the Tencel fibers more compact, limiting excessive expansion due to moisture absorption, thereby reducing dimensional instability caused by the high hygroscopicity of Tencel fibers. When combined with pure cotton weft yarn, the difference in twist coefficients between the two balances, to some extent, the changes in internal stress caused by the different hygroscopicities of the fibers, helping the fabric maintain relatively stable dimensions under changes in wet and dry environments and improving the fabric's shape retention.

[0029] The higher twist coefficient gives Tencel weft yarn better strength and abrasion resistance. When subjected to external friction or stretching, Tencel weft yarn can work together with pure cotton weft yarn to resist external forces, enhancing the fabric's shape retention during use. This difference in twist coefficient also allows the two yarns to maintain the fabric's softness while increasing its overall toughness after interweaving.

[0030] Tencel weft yarn has a high twist coefficient, resulting in relatively small changes in the gaps between fibers during moisture absorption. This allows it to maintain good capillary channels, promoting sweat transmission and improving moisture absorption and wicking efficiency.

[0031] Preferably, the twist direction of the Tencel weft yarn is opposite to that of the pure cotton weft yarn.

[0032] Opposite twist directions allow the two yarns to restrain each other. When one yarn attempts to deform due to internal stress, the other yarn can provide some resistance due to the opposite twist direction, thereby reducing the problem of fabric deformation caused by internal fiber stress and improving the fabric's shape retention.

[0033] In some embodiments, the ratio of Tencel weft yarn to pure cotton weft yarn is 1:1.

[0034] Tencel fibers have good moisture absorption but a high shrinkage rate, while pure cotton fibers have relatively weaker moisture absorption but better stability. A 1:1 blend of the two achieves a good balance between moisture absorption and dimensional stability. In terms of sweat absorption, Tencel fibers leverage their excellent moisture absorption to quickly absorb sweat, while pure cotton fibers ensure that the fabric does not undergo significant dimensional changes due to excessive expansion and contraction after absorbing moisture. This allows the fabric to maintain good dimensional stability while possessing excellent moisture absorption, meeting the dual requirements of wearing comfort and shape retention.

[0035] Preferably, in the lower layer, the pure cotton weft yarn is located between adjacent Tencel weft yarns. (Substitute...) Figure 1 For example, A and C are pure cotton weft yarns, while B and D are Tencel weft yarns.

[0036] The even distribution of the two yarns in the fabric is conducive to the consistency of the overall performance of the fabric. Whether it is the tensile strength, wrinkle resistance or appearance smoothness of the fabric, there will be no local differences due to the uneven distribution of a certain fiber, thus ensuring the stability of the fabric quality.

[0037] Tencel weft yarns are relatively smooth, while pure cotton weft yarns are soft. The pure cotton weft yarns are located between adjacent Tencel weft yarns, allowing the fabric to simultaneously experience the characteristics of both yarns when in contact with the skin, creating a unique soft and smooth feel and enhancing wearing comfort.

[0038] The Tencel weft yarn and the pure cotton weft yarn have the same count, which helps ensure the stability of the fabric's structure. This stable interweaving structure helps improve the fabric's strength and durability. It also allows both cotton and Tencel fibers to come into contact with the skin simultaneously, fully utilizing the moisture absorption and skin-friendly properties of the second weft yarn.

[0039] In some embodiments, the second weft yarn is thicker than the honeycomb polyester weft yarn.

[0040] The coarser second weft yarns, including pure cotton and Tencel weft yarns, have better moisture absorption. The honeycomb polyester weft yarn is finer and more likely to be positioned between the upper pure cotton warp yarns and the lower layer, allowing the skin to come into contact with the cotton and Tencel fibers first, thus enabling the honeycomb polyester weft yarn to wick moisture away from the upper layer in the middle of the fabric.

[0041] Combining the above preferred solutions, when the fabric is in close contact with the skin, the cotton and Tencel fibers are in direct contact, possessing excellent moisture absorption and skin-friendliness, and can quickly absorb sweat. The honeycomb polyester weft yarn is relatively fine, mostly covering the middle of the upper and lower layers of the fabric. The porous honeycomb polyester has excellent moisture-wicking properties. The cotton and Tencel fibers transfer the absorbed sweat through capillary action and conduct it quickly through the porous honeycomb polyester. The sweat can quickly spread on the fabric surface and evaporate rapidly under external influences. In the second weft yarn, the pure cotton weft yarn and the Tencel weft yarn are arranged in a 1:1 ratio with the same yarn count. The twist directions of the two yarns are opposite, which helps to eliminate the problem of fabric deformation caused by internal fiber stress. Furthermore, the twist coefficient of the Tencel weft yarn is relatively higher than that of the pure cotton weft yarn, further suppressing the dimensional changes caused by the stronger moisture absorption of Tencel fibers compared to cotton fibers. Therefore, it can effectively solve the problem of poor fabric shape retention.
