A denim fabric that is resistant to fraying and comfortable to wear

Abstract

This utility model discloses a denim fabric that is resistant to pilling and comfortable to wear, belonging to the textile field. It includes interwoven weft yarns and pure cotton warp yarns. The weft yarns consist of parallel irregularly shaped nylon, plied yarns, and hollow polyester. The plied yarns are composed of linen yarns and elastic core-spun yarns. The elastic core-spun yarns include an elastic core and a cotton fiber covering layer on the surface of the elastic core. The plied yarns combine the elastic core-spun yarns and linen yarns, which helps improve the poor elasticity of linen yarns and reduces the exposed surface of the linen yarns, thus inhibiting pilling of linen fibers and reducing direct contact between linen fibers and the skin. It also retains the good moisture absorption and wicking capabilities of linen yarns. Furthermore, the use of irregularly shaped nylon and hollow polyester with strong moisture-wicking properties, which are not easily deformed, further enhances the fabric's moisture absorption and wicking properties, while also limiting linen yarn shrinkage and further reducing contact between linen yarns and the skin.

Description

Technical Field

[0001] This utility model relates to a denim fabric that is tear-resistant and comfortable to wear, belonging to the textile field. Background Technology

[0002] Denim clothing has stood the test of time in the fashion world for over a century, becoming an irreplaceable product and enjoying widespread popularity. In the research and development of denim fabrics, designers have broken through the limitations of traditional pure cotton denim, developing and designing denim fabrics with different functions and performance characteristics based on market demands, continuously meeting those needs.

[0003] Natural linen fiber has excellent moisture absorption and dissipation properties, achieving a cooling effect, making it a key raw material for developing summer fabrics. However, due to the inherent structural characteristics of linen fiber, individual fibers are uneven, with high crystallinity and orientation, resulting in high breaking strength, high rigidity, and poor elasticity. Fabrics woven from linen fibers often have short stripes of varying widths, making them prone to pilling and fuzzing during wear. Furthermore, linen fabrics in summer have poor wrinkle and shrinkage resistance; after daily wear and household washing, the weft direction is prone to shrinkage, leading to wrinkles and unevenness on the fabric surface. Additionally, linen fabrics can feel rough and uncomfortable against the skin. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a denim fabric that is resistant to tearing and comfortable to wear, does not easily pill, and has better shape retention.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A tear-resistant and comfortable denim fabric comprising interwoven weft yarns and pure cotton warp yarns, wherein the weft yarns comprise parallel irregularly shaped nylon, ply yarns and hollow polyester, wherein the ply yarns are composed of linen yarns and elastic core-spun yarns, and wherein the elastic core-spun yarns comprise elastic core yarns and a cotton fiber covering layer covering the surface of the elastic core yarns.

[0007] The tear-resistant and comfortable denim fabric provided in this application features pure cotton warp yarns with excellent moisture absorption and comfort, ensuring a skin-friendly feel when in contact with the fabric. The irregularly shaped nylon helps wick away moisture and promote breathability. The linen yarns in the ply yarns have excellent moisture absorption and dissipation properties, quickly absorbing human sweat and transferring it to the irregularly shaped nylon and hollow polyester, then releasing it to achieve a cooling effect, meeting the needs of summer wear. By combining with elastic core-spun yarn, the elastic core yarn imparts a certain elasticity to the ply yarn, compensating for the insufficient elasticity of linen fibers, making the fabric more conform to the body's movements and less prone to deformation. The cotton fiber covering layer protects the elastic core yarn and enhances the bonding force with the linen yarn; the cotton fiber itself also has moisture absorption properties, working synergistically with the linen yarn to further improve moisture absorption. These yarns with different properties interweave and work together to give the fabric excellent moisture absorption and breathability, comfortable wear, and good tear resistance, meeting people's diverse functional needs for denim fabric.

[0008] Furthermore, the twist coefficient of the linen yarn is 5% to 10% lower than that of the elastic core-spun yarn.

[0009] This difference in twist coefficient helps the ply yarn to better coordinate with other weft yarns and pure cotton warp yarns during the interlacing process, improving the overall stability of the fabric structure.

[0010] Furthermore, the twist direction of the linen yarn is opposite to that of the elastic core-spun yarn.

[0011] Because of their opposite twist directions, the linen yarn and the elastic core-spun yarn form a mutually restraining state within the ply. When the fabric is subjected to external forces, the internal stresses generated by the linen yarn and the elastic core-spun yarn can cancel each other out.

[0012] Furthermore, the irregularly shaped nylon is thicker than the ply yarn.

[0013] The coarser, irregularly shaped nylon strands help to "support" the yarns in the fabric, reducing direct contact between the hemp fibers and the skin.

[0014] Furthermore, the hollow polyester fiber is thicker than the ply yarn.

[0015] The thicker hollow polyester fibers can conceal the ply yarns to some extent, reducing direct contact between the linen fibers and the skin. The excellent moisture-wicking properties of hollow polyester, combined with its larger diameter, create more efficient moisture-wicking channels, working synergistically with the moisture-absorbing properties of the linen yarns within the ply yarns. After the linen yarns absorb sweat, the hollow polyester quickly transfers the sweat to the outer layer of the fabric, accelerating perspiration and improving the fabric's moisture-wicking capacity, keeping the wearer dry and comfortable and enhancing the wearing experience.

[0016] Furthermore, the irregularly shaped nylon and the hollow polyester have the same thickness.

[0017] This design results in a more even distribution of stress on the fabric. This uniform structure, when interwoven with pure cotton warp yarns, allows for a tighter and smoother weave between the warp and weft yarns, enhancing the fabric's texture and appearance, and improving wearing comfort.

[0018] Furthermore, the irregularly shaped nylon, the ply yarn, and the hollow polyester are arranged side by side in a 1:1:1 ratio.

[0019] This ratio ensures that the three weft yarns play a relatively balanced role in the fabric. If the proportion of irregularly shaped nylon is too low, the fabric's strength and tear resistance may decrease; if the proportion of ply yarn is too low, its moisture absorption and wicking properties and elasticity may be affected.

[0020] Furthermore, the denim fabric, which is tear-resistant and comfortable to wear, has a twill weave structure.

[0021] Furthermore, the pure cotton warp yarn 1 and the weft yarn are interlaced in a three-up-one-down pattern.

[0022] Furthermore, the weft yarn forms an angle of 10° to 45° with the width direction of the fabric.

[0023] The angle between the weft yarn and the width direction allows the fabric to more effectively disperse external forces when subjected to force in different directions.

[0024] The beneficial effects of this invention are as follows: In the denim fabric of this invention, which is resistant to tearing and comfortable to wear, the ply yarn combines elastic core-spun yarn and linen yarn, which helps to improve the problem of poor elasticity of linen yarn and reduces the exposed surface of linen yarn, which helps to inhibit pilling of linen fibers and reduce direct contact between linen fibers and the skin, while retaining the good moisture absorption and wicking ability of linen yarn. Furthermore, the ply yarn is combined with irregularly shaped nylon and hollow polyester with strong moisture-wicking ability and is not easily deformed, so that the fabric has both moisture absorption and moisture wicking properties, and can also limit the shrinkage of linen yarn, further reducing the contact between linen yarn and the skin.

[0025] 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.

[0030] 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.

[0031] 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.

[0032] Reference Figure 1 and Figure 3 This application provides a denim fabric that is tear-resistant and comfortable to wear, including interwoven weft yarns and pure cotton warp yarns 1. The weft yarns include parallel irregularly shaped nylon 2, ply yarns 3 and hollow polyester 4. The ply yarns 3 are made of linen yarns 31 and elastic core-spun yarns 32. The elastic core-spun yarns 32 include elastic core yarns 321 and cotton fiber covering layers 322 covering the surface of the elastic core yarns 321.

[0033] In this embodiment, the ply yarn combines elastic core-spun yarn and linen yarn, which helps to improve the problem of poor elasticity of linen yarn.

[0034] Meanwhile, the ply yarn combines elastic core-spun yarn and linen yarn, reducing the exposed surface of the linen yarn, which helps to suppress pilling of linen fibers and reduces direct contact between linen fibers and the skin, making the fabric more comfortable to the touch. The weft yarn also contains irregularly shaped nylon and hollow polyester, further reducing the chance of linen yarn contact with the skin.

[0035] The elastic core-spun yarn, which is plied with the linen yarn, restricts the shrinkage of the linen yarn; the irregularly shaped nylon, hollow polyester, and plied yarn are all interwoven with the pure cotton warp yarn, so the irregularly shaped nylon and hollow polyester, which are not easily deformed, can restrain the plied yarn and further limit the shrinkage of the linen yarn.

[0036] This application embodiment retains the good moisture absorption and wicking capabilities of linen yarn, and further combines it with nylon with a highly moisture-wicking profile, hollow polyester, and plied yarn, giving the fabric both moisture absorption and wicking properties. Specifically, the cross-section of the nylon with a profile is as follows: Figure 2 As shown, the grooves on the surface can be used to quickly wick away moisture.

[0037] exist Figure 1 In a representative embodiment, the pure cotton warp yarn 1 and weft yarn are interwoven in a three-up-one-down twill pattern, which can present the unique texture of traditional denim fabric.

[0038] In some embodiments, the twist coefficient of the linen yarn 31 is 5% to 10% lower than that of the elastic core-spun yarn.

[0039] Linen yarn has a low twist coefficient, making it relatively soft and reducing the harshness caused by the inherent rigidity of linen fibers, thus improving wearing comfort. When the fabric is stretched, the elastic core-spun yarn, with its relatively high twist coefficient and elastic core yarn, initially withstands the greater tension, better distributing the force. The combination of linen yarn and elastic core-spun yarn not only enhances the overall tensile performance of the yarn but also strengthens the fabric's resistance to external forces during wear, reducing the likelihood of tearing due to uneven stress.

[0040] In some embodiments, the twist direction of the linen yarn 31 is opposite to that of the elastic core-spun yarn.

[0041] When the fabric is subjected to tensile force, the tensile stress generated by the linen yarn due to its own structure interacts with the stress generated by the elastic core-spun yarn under opposite twisting directions, thereby reducing the overall deformation of the ply yarn caused by external force. This stress self-cancellation mechanism effectively improves the ply yarn's resistance to deformation, thus enhancing the fabric's stability and reducing the possibility of tearing caused by ply yarn deformation. Simultaneously, this stress cancellation effect allows the ply yarn to better adapt to various body movements during daily wear, reducing excessive twisting or deformation due to uneven local stress, and improving wearing comfort. Moreover, because the internal stress of the ply yarn is effectively controlled, the fabric can still maintain a good shape after multiple washes and wears, extending the fabric's lifespan.

[0042] Linen fibers are inherently rigid and have a relatively rough surface. When in direct contact with other fabrics (underwear, outerwear), they are prone to generating significant friction, which may lead to problems such as pilling and fuzzing. They can also feel prickly or stiff when in contact with the skin.

[0043] Preferably, the irregularly shaped nylon 2 is thicker than the ply yarn 3, and the hollow polyester 4 is thicker than the ply yarn 3. This reduces the chance of friction between the hemp fibers and other fabrics, thereby reducing the possibility of pilling and improving the appearance quality and durability of the fabric. It also reduces the chance of hemp fibers coming into contact with the skin, which helps to improve the comfort of the fabric. At the same time, the thicker irregularly shaped nylon and hollow polyester, when interwoven with pure cotton warp yarns, can form a tighter interlacing point with the pure cotton warp yarns due to their larger diameter, enhancing the bonding force between the weft and warp yarns, further improving the overall stability of the fabric, and effectively preventing fabric tearing.

[0044] Meanwhile, the irregularly shaped nylon 2 and the hollow polyester 4 have the same thickness.

[0045] When the fabric is subjected to external force, the irregularly shaped nylon and hollow polyester can jointly and relatively evenly bear the force, thus effectively improving the fabric's tear resistance. In terms of moisture wicking, the two are of equal thickness, forming a relatively uniform moisture wicking channel in the fabric. The irregularly shaped nylon wicks away moisture due to its special structure, while the hollow polyester wicks away moisture through its hollow structure. Together, they can more efficiently transfer sweat from the skin surface to the outer layer of the fabric.

[0046] In some embodiments, the irregularly shaped nylon 2, the ply yarn 3, and the hollow polyester 4 are arranged side by side in a ratio of 1:1:1.

[0047] This ratio ensures a relatively balanced role for the three yarns in the fabric. From a tear resistance perspective, each yarn can fully utilize its advantages in the fabric structure, supporting each other and jointly resisting external forces, avoiding deficiencies in certain fabric properties due to insufficient amounts of any one yarn. For example, if the proportion of irregularly shaped nylon is too low, the fabric's strength and tear resistance may decrease; if the proportion of ply yarn is too low, moisture absorption and wicking, as well as elasticity, may be affected. In terms of moisture absorption, wicking, and warmth retention, the 1:1:1 ratio achieves a good balance between moisture absorption and wicking (linen yarn), moisture wicking (irregularly shaped nylon and hollow polyester), and warmth retention (hollow polyester). The even distribution of the three yarns ensures good moisture absorption, wicking, and warmth retention in all areas of the fabric, preventing localized overheating, over-humidity, or over-cold. Moreover, this uniform ratio contributes to the stability of the fabric's weaving process, making the interweaving of the weft yarn and the pure cotton warp yarn smoother, ensuring the overall quality stability of the fabric, and improving wearing comfort.

[0048] Preferably, the weft yarn forms an angle of 10° to 45° with the width direction of the fabric.

[0049] When the fabric is subjected to tension in the horizontal or vertical direction, the inclined structure can decompose the force into different directions, thereby improving the fabric's tear resistance. This angle setting can also change the appearance of the fabric to a certain extent, giving the fabric surface a unique texture effect, increasing the uniqueness and fashion sense of denim fabric, and enhancing the wearer's wearing experience.

[0050] Combining the above-mentioned preferred technical methods, the selected fabric allows for rapid wicking of sweat on the skin-contacting underside during wear. This is because the irregularly shaped nylon and hollow polyester have excellent moisture-wicking capabilities and are in direct contact with the skin. The surface of the ply yarn is composed of hemp fibers (specifically, hemp) and cotton fibers, possessing excellent moisture absorption. Simultaneously, hemp fibers have good moisture dissipation properties, enabling rapid evaporation of sweat under natural conditions. The irregularly shaped nylon and hollow polyester have low water absorption rates, making the fabric dimensions less prone to change during household washing. Furthermore, the finer ply yarns are easily concealed by the thicker weft yarns, which improves the fabric's weft-direction tear resistance. The opposite twist direction of the hemp yarn and the elastic core-spun yarn allows the ply yarns to counteract dimensional changes caused by internal fiber stress, thus achieving a wrinkle-resistant effect.
