Description

Technical Field

[0001] The utility model relates to the technical field of fabrics, in particular to an elastic nylon fabric. Background Art

[0002] With the change of modern lifestyle, outdoor sports have become an important way for more and more people to pursue health and fun. At the same time, the emphasis on skin protection and healthy lifestyle has also led to the booming market of functional sun protection clothing. Lightweight, portable and excellent elastic sun protection clothing is deeply loved by consumers because it can meet the needs of athletes for free and unrestrained sports experience. In such a market context, the development of a sun protection clothing fabric that is both light and thin and has excellent elasticity and UV resistance is undoubtedly in line with the current market trend. In terms of fabric technology, elastic fabrics are divided into two types: double-sided elastic and elastic nylon. Among them, elastic nylon has a particularly outstanding elastic performance due to its high content of spandex. However, for low-denier spandex elastic fabrics, due to their special structure, such as low-denier chemical fibers coated with 20D spandex yarns, the content ratio of low-denier chemical fibers to spandex is close to or even slightly less, which makes it difficult to maintain stable tension when used as warp yarn, thus affecting the overall weaving and dyeing process, resulting in abnormalities. Therefore, most of the low-denier elastic fabrics on the market are still at the stage of weft-elastic fabrics, while low-denier elastic nylon elastic anti-ultraviolet fabrics are almost blank. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned defects or problems existing in the background technology, and to provide an elastic nylon fabric, which adopts a ZS double-coating structure in the warp direction to ensure the overall tension of the coated yarn and improve the elasticity and stability of the fabric. At the same time, by adjusting the density in the warp and weft directions, the fabric not only has an excellent cooling effect, but also has good UV resistance and optimized air permeability.

[0004] To achieve the above objectives, each embodiment of the present invention adopts the following technical solutions but is not limited to the following solutions:

[0005] The first technical solution relates to an elastic nylon fabric, including a fabric layer, wherein the fabric layer is interwoven with warp yarns and weft yarns in a plain weave manner, the warp yarns are a ZS double-covered yarn structure of low-denier nylon coated with spandex, the twisting method is Z twist and S twist simultaneously, and the twist degree is 1800 to 2000 twists.

[0006] The second technical solution is based on the first technical solution, wherein the warp yarn is 12D nylon bright yarn covered with 20D spandex.

[0007] The third technical solution is based on the second technical solution, wherein the weft yarn is nylon matte yarn coated with spandex.

[0008] The fourth technical solution is based on the third technical solution, wherein the nylon is bio-based PA510 fiber.

[0009] The fifth technical solution is based on the fourth technical solution, wherein the warp density of the fabric layer is 260 to 280 strands / 10 cm, and the weft density of the fabric layer is 210 to 220 strands / 10 cm.

[0010] The sixth technical solution is based on the fifth technical solution, wherein the yarn forms of the warp yarn and the weft yarn of the fabric layer are FDY.

[0011] The seventh technical solution is based on the first technical solution, which further includes a water-repellent layer, and the water-repellent layer is located above the fabric layer.

[0012] The eighth technical solution is based on the seventh technical solution, wherein the water-repellent layer is made of fluorine-free bio-based polyaliphatic compound.

[0013] From the above description of the various embodiments of the present invention, it can be seen that, compared with the prior art, the various embodiments of the present invention have the following beneficial effects:

[0014] In the first technical solution and related embodiments, low-denier elastic nylon fabric is very suitable for outdoor clothing such as sunscreen clothing that needs to be worn for a long time because of its fine fiber fineness, soft feel and comfortable wearing. In addition, the elasticity of low-denier fiber is also good, which can adapt to various activities of the body and provide good freedom of movement. However, low-denier spandex elastic fabric is prone to unstable tension when used as warp yarn, mainly due to its special structure, and the content ratio of low-denier nylon fiber and spandex is close to or even slightly less. This structure makes it difficult for the fabric to maintain stable tension in the warp direction when stretched, because the elasticity of spandex yarn is large, and the supporting effect of low-denier nylon fiber is relatively weak, and whitening is easy to occur in the weaving and dyeing process, resulting in product abnormality. The fabric layer is interwoven with a plain weave texture through warp yarn and weft yarn with an up-and-down tissue texture. In this structure, both the warp yarn and the weft yarn are designed with a nylon-coated spandex coated yarn. In particular, the warp yarn is prepared by machine twisting, in which Z twist and S twist are performed alternately and simultaneously to balance the internal stress of the fiber and ensure the stability of the overall tension of the covered yarn. In addition, the twist is controlled within the range of 1800 to 2000 twists to optimize the coating effect of nylon fiber on spandex and reduce the friction on the yarn surface, thereby improving the smoothness of the fabric.

[0015] In the second technical solution and related embodiments, the warp yarn is made of 12D nylon bright yarn coated with 20D spandex. The 12D nylon bright yarn has high strength and wear resistance, so that the fabric remains soft and comfortable while also enhancing durability, and can withstand the test of daily wear and washing. In addition, the characteristics of the bright yarn make the fabric present a unique gloss under the light, increasing the aesthetics. As an elastic fiber, 20D spandex gives the fabric excellent elasticity and recovery. The fineness of this spandex is moderate, which can ensure the elasticity of the fabric without being too thick, making the fabric lighter and more breathable.

[0016] In the third technical solution and related embodiments, the weft yarn is made of nylon matte yarn coated with spandex. The use of nylon matte yarn makes the fabric visually present a low-key and elegant luster, avoiding an overly glaring luster, which is more in line with modern people's aesthetic needs for simplicity and restraint. This matte effect not only improves the overall texture of the fabric, but also enables it to maintain a stable appearance under different light conditions. The warp yarn is made of nylon bright yarn, and the weft yarn is made of nylon matte yarn. Through the interweaving of bright and matte yarns, the fabric visually presents a unique luster effect and texture changes. This combination can bring unique visual effects and styles to the fabric.

[0017] In the fourth technical solution and related embodiments, bio-based PA510 fiber, as a bio-based material, has green and environmentally friendly characteristics. Bio-based PA510 fiber also gives the fabric more excellent moisture absorption, softness, high strength, wear resistance, easy dyeing and other characteristics. These characteristics make the elastic nylon fabric more comfortable to wear, can adapt to various activities of the human body, and maintain good appearance and performance.

[0018] In the fifth technical solution and related embodiments, the elastic nylon fabric achieves the dual advantages of high elasticity and structural stability by reasonably adjusting the density in the warp and weft directions. The warp density is controlled between 260 and 280 strands / 10cm, and the weft density is within the range of 210 and 220 strands / 10cm. This density control makes the fabric more compact and uniform. The gaps between the yarns are effectively controlled, neither too large nor too small, thereby enhancing the overall structural stability and durability of the fabric. At the same time, the structural design of the elastic nylon fabric allows air to flow freely inside the fabric. The control of the warp and weft density not only ensures the tightness of the fabric, but also gives it excellent breathability. The shrinkage characteristics of spandex yarn can enhance the density between fibers, thereby enhancing the anti-ultraviolet function of the fabric. In addition, the excellent elasticity and elasticity of spandex also add more advantages to the fabric. It can freely expand and contract with the movement of the human body, ensuring that the fabric always remains fit and comfortable. This feature not only improves the wearing experience of the fabric, but also further enhances its breathability.

[0019] In the sixth technical solution and related embodiments, when nylon FDY is used to coat spandex in both the warp and weft directions, the technical effect of the elastic nylon fabric in the form of FDY (fully stretched yarn) yarn is further improved. Specifically, the use of nylon FDY yarn significantly enhances the smoothness of the fabric. Since FDY yarn has good surface smoothness and uniformity, the surface of the fabric is more delicate and continuous, reducing the friction and resistance between the yarns. This smooth surface not only enhances the tactile experience of the fabric, but also increases the surface area of ​​the fabric when it contacts the human body. When the fabric contacts the human body, the increased surface area helps to increase the air circulation between the skin and the fabric, and promotes the evaporation and heat dissipation of sweat. Therefore, this elastic nylon fabric can bring a cooler feeling when worn, and is particularly suitable for wearing in summer or high temperature environments. In addition, the structure of nylon FDY coated with spandex also gives the fabric excellent elasticity and recovery. The addition of spandex allows the fabric to freely expand and contract with the movement of the human body, maintaining fit and comfort. The strength and wear resistance of nylon FDY further enhance the durability of the fabric.

[0020] In the seventh technical solution and related embodiments, the combination of the water-repellent layer and the elastic nylon fabric not only retains the original elasticity, comfort and durability of the fabric, but also adds a waterproof function, making the functionality of the fabric richer and more comprehensive. In addition, the provision of the water-repellent layer does not affect the air permeability of the elastic nylon fabric. The fabric can still maintain good air permeability, allowing the wearer to feel comfortable and cool while being waterproof.

[0021] In the eighth technical solution and related embodiments, a fluorine-free bio-based polyaliphatic compound is used as a water-repellent layer of elastic nylon fabric, which is not only environmentally friendly and safe, but also has excellent water-repellent performance and smoothness, which improves the practicality and comfort of the fabric. The fluorine-free property makes this water-repellent layer more environmentally friendly and safe. The bio-based polyaliphatic compound can effectively reduce the tension on the surface of the fabric, thereby achieving the function of water repellent. This compound forms a dense film on the surface of the fabric, making it difficult for water droplets to penetrate, while not affecting the air permeability of the fabric. In addition, the compound can also reduce the friction on the surface of the fabric, making the surface of the fabric more smooth. This feature not only enhances the tactile experience of the fabric, but also makes the fabric more wear-resistant and less prone to wrinkling during wearing and washing, further extending the service life of the fabric.

[0032] See also Figure 1 to Figure 2 , Figure 2 Shows a schematic diagram of the elastic nylon fabric structure; Figure 2 As shown, an elastic nylon fabric comprises a water-repellent layer 1 and a fabric layer 2.

[0033] Water repellent layer 1, such as Figure 2 As shown, it is located above the fabric layer 2, and the water-repellent layer 1 adopts a fluorine-free bio-based poly-aliphatic compound. Specifically, the water-repellent layer 1 uses a fluorine-free bio-based poly-aliphatic compound of Rudolf RUCO-DRY BIO CGR Technology. In this embodiment, the water-repellent layer 1 adopts a fluorine-free bio-based poly-aliphatic compound, which is not only environmentally friendly and safe, but also has excellent water-repellent performance and smoothness, which improves the practicality and comfort of the fabric. The fluorine-free property makes this water-repellent layer 1 more environmentally friendly and safe. Bio-based poly-aliphatic compounds can effectively reduce the tension on the surface of the fabric, thereby achieving the function of water repellency. This compound forms a dense film on the surface of the fabric, making it difficult for water droplets to penetrate, while not affecting the breathability of the fabric. In addition, the compound can also reduce the friction on the surface of the fabric, making the surface of the fabric more smooth. This feature not only enhances the tactile experience of the fabric, but also makes the fabric more wear-resistant and less prone to wrinkling during wearing and washing, further extending the service life of the fabric. In this embodiment, the combination of the water-repellent layer 1 and the elastic nylon fabric not only retains the original elasticity, comfort and durability of the fabric, but also adds a waterproof function, making the functionality of the fabric more abundant and comprehensive. In addition, the provision of the water-repellent layer 1 does not affect the air permeability of the elastic nylon fabric. The fabric can still maintain good air permeability, allowing the wearer to feel comfortable and cool while being waterproof.

[0034] Fabric layer 2, such as Figure 1 As shown, it is interwoven by warp yarn and weft yarn in plain weave, the warp yarn is a ZS double-covered yarn structure of low-denier nylon coated spandex 3, the twisting method is Z twist 4 and S twist 5 simultaneously, and the twist is 1800 twists to 2000 twists. Specifically, the warp yarn is 12D nylon bright yarn coated with 20D spandex 3, the weft yarn is nylon matte yarn coated with spandex 3, and the nylon is bio-based PA510 fiber. The warp density of fabric layer 2 is 260 to 280 strands / 10cm, and the weft density of fabric layer 2 is 210 to 220 strands / 10cm. The yarn morphology of the warp and weft yarns of fabric layer 2 is FDY.

[0035] In the present embodiment, the low-denier elastic nylon fabric is very suitable for outdoor clothing such as sunscreen clothing that needs to be worn for a long time because of its fine fiber fineness, soft feel and comfortable wearing. In addition, the elasticity of low-denier fiber is also good, which can adapt to various activities of the body and provide good freedom of movement. However, the problem of unstable tension is prone to occur in the low-denier spandex 3 elastic fabric when used as warp yarn, mainly due to its special structure, and the content ratio of low-denier nylon fiber and spandex 3 is close to or even slightly less. This structure makes the fabric difficult to maintain stable tension in the warp direction due to the large elasticity of spandex 3 yarn and the relatively weak supporting effect of low-denier nylon fiber when stretched, and easy to produce whitening in the weaving and dyeing and finishing process, resulting in product abnormality. Fabric layer 2 is interwoven with a plain weave texture by warp yarn and weft yarn with an up-and-down tissue texture. In this structure, the warp yarn and weft yarn are all designed with a nylon-coated spandex 3 coated yarn. In particular, the warp yarn is prepared by machine twisting, in which Z twist 4 and S twist 5 are performed alternately and simultaneously to balance the internal stress of the fiber and ensure the stability of the overall tension of the covered yarn. In addition, the twist is controlled within the range of 1800 to 2000 twists to optimize the coating effect of nylon fiber on spandex 3 and reduce the friction on the yarn surface, thereby improving the smoothness of the fabric.

[0036] In this embodiment, the warp yarn is made of 12D nylon bright yarn coated with 20D spandex 3. The 12D nylon bright yarn has high strength and wear resistance, so that the fabric remains soft and comfortable while also enhancing durability, and can withstand the test of daily wear and washing. In addition, the characteristics of the bright yarn make the fabric present a unique gloss under the light, which increases the aesthetics. As an elastic fiber, the 20D spandex 3 gives the fabric excellent elasticity and resilience. The fineness of this spandex 3 is moderate, which can ensure the elasticity of the fabric without being too thick, making the fabric thinner and more breathable.

[0037] In this embodiment, the weft yarn is made of nylon matte yarn coated with spandex 3. The use of nylon matte yarn makes the fabric visually present a low-key and elegant luster, avoiding an overly glaring luster, which is more in line with modern people's aesthetic needs for simplicity and restraint. This matte effect not only improves the overall texture of the fabric, but also enables it to maintain a stable appearance under different light conditions. The warp yarn is made of nylon bright yarn, and the weft yarn is made of nylon matte yarn. Through the interweaving of bright and matte yarns, the fabric visually presents a unique luster effect and texture changes. This combination can bring unique visual effects and styles to the fabric.

[0038] In this embodiment, bio-based PA510 fiber, as a bio-based material, has the characteristics of green environmental protection. Bio-based PA510 fiber also gives the fabric more excellent moisture absorption, softness, high strength, wear resistance, easy dyeing and other characteristics. These characteristics make the elastic nylon fabric more comfortable to wear, can adapt to various activities of the human body, and maintain good appearance and performance.

[0039] In this embodiment, the elastic nylon fabric achieves the dual advantages of high elasticity and structural stability by reasonably adjusting the density in the warp and weft directions. The warp density is controlled between 260 and 280 strands / 10cm, and the weft density is within the range of 210 and 220 strands / 10cm. This density control makes the fabric more compact and uniform. The gaps between the yarns are effectively controlled, neither too large nor too small, thereby enhancing the overall structural stability and durability of the fabric. At the same time, the structural design of the elastic nylon fabric allows air to flow freely inside the fabric. The control of the warp and weft density not only ensures the tightness of the fabric, but also gives it excellent air permeability. The shrinkage characteristics of spandex 3 yarn can improve the density between fibers, thereby enhancing the anti-ultraviolet function of the fabric. In addition, the excellent elasticity and elasticity of spandex 3 also add more advantages to the fabric. It can freely expand and contract with the activities of the human body, ensuring that the fabric always remains fit and comfortable. This feature not only improves the wearing experience of the fabric, but also further enhances its breathability.

[0040] In this embodiment, when nylon FDY is used to coat spandex 3 in both the warp and weft directions, the technical effect of this elastic nylon fabric using FDY (fully stretched yarn) yarn form is further improved. Specifically, the use of nylon FDY yarn significantly enhances the smoothness of the fabric. Since FDY yarn has good surface smoothness and uniformity, the surface of the fabric is more delicate and continuous, reducing the friction and resistance between the yarns. This smooth surface not only enhances the tactile experience of the fabric, but also increases the surface area of ​​the fabric when it contacts the human body. When the fabric contacts the human body, the increased surface area helps to increase the air circulation between the skin and the fabric, promoting the evaporation and heat dissipation of sweat. Therefore, this elastic nylon fabric can bring a cooler feeling when worn, and is particularly suitable for wearing in summer or high temperature environments. In addition, the structure of nylon FDY coated spandex 3 also gives the fabric excellent elasticity and resilience. The addition of spandex 3 allows the fabric to freely expand and contract with the movement of the human body, maintaining fit and comfort. The strength and wear resistance of nylon FDY further enhance the durability of the fabric.

[0041] The description of the above specification and embodiments is used to explain the protection scope of the utility model, but does not constitute a limitation on the protection scope of the utility model. Through the enlightenment of the utility model or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent replacements or other improvements to the embodiments of the utility model or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the utility model.
