Abstract
Description
Technical Field
[0001] This application relates to the field of textile fabric technology, and in particular to a nylon-spandex superelastic fabric. Background Technology
[0002] Trousers are primarily secured to the body at the waistband. For stability, the waistband needs enhanced anti-slip properties, while also requiring significant elasticity for easy on and off. Existing waistbands either lack anti-slip design or use ordinary elastic fabric with silicone anti-slip strips for this purpose.
[0003] However, using silicone anti-slip strips would affect breathability and increase manufacturing complexity, while also impacting the elasticity of the waistband. Furthermore, the anti-slip performance of the silicone strips would weaken with repeated stretching. Therefore, this application proposes a nylon-spandex superelastic fabric, primarily suitable for waistband production. Waistbands made using this fabric combine high elasticity with good anti-slip properties. Utility Model Content
[0004] In order to make the waistband both highly elastic and have good anti-slip properties, this application provides a nylon-spandex superelastic fabric.
[0005] The technical solution for the nylon-spandex superelastic fabric provided in this application is as follows:
[0006] A nylon-spandex superelastic fabric includes a first side and a second side, the first side and the second side being formed by weft knitting yarn using a double-sided weft knitting machine, the yarn being a blend of nylon and spandex; the first side has multiple sets of first protrusions and multiple sets of second protrusions, the multiple first protrusions in each set being arranged at intervals along the transverse direction of the first side, the multiple second protrusions in each set being arranged at intervals along the transverse direction of the first side; the multiple sets of second protrusions and the multiple sets of first protrusions are arranged at intervals along the longitudinal direction of the first side.
[0007] By adopting the above technical solutions, nylon material possesses high strength and abrasion resistance, which can improve the overall durability of the fabric; while spandex material gives the fabric excellent elastic recovery ability, allowing it to quickly return to its original shape after stretching; in addition, the fabric is woven using a double-sided weft knitting machine, thus ensuring that the positioning waistband made from this fabric has good elasticity. The first and second protrusions set on the first side increase the roughness of the fabric, increasing the roughness of the fabric structure itself, thereby improving the anti-slip performance of the waistband made from this fabric.
[0008] Optionally, the first protrusion is strip-shaped and extends laterally along the first surface.
[0009] By adopting the above technical solution, the fabric achieves a more continuous and uniform elastic support effect in the transverse direction. The strip-shaped first protrusion extends transversely along the first surface, which not only enhances the structural stability of the fabric in this direction, but also effectively improves the uniformity of stress distribution when the fabric is stretched, thereby avoiding problems such as local deformation or uneven stress and improving the comfort of the waistband made of this fabric.
[0010] Optionally, the second protrusion is strip-shaped and extends longitudinally along the first surface.
[0011] By adopting the above technical solution, with the first protrusion extending laterally along the first surface and the second protrusion extending longitudinally along the first surface, the overall stability and elasticity distribution uniformity of the fabric are further effectively improved. Simultaneously, since both the first and second protrusions are strip-shaped, the anti-slip contact area of the fabric is increased, further improving the anti-slip performance of the waistband made from this fabric, while also enhancing wearing comfort and support. Furthermore, the fabric's wrinkle resistance is increased, allowing it to maintain a good appearance even after prolonged use.
[0012] Optionally, the line connecting two adjacent groups of second protrusions passes through the gap between adjacent first protrusions in the same group.
[0013] By employing the above technical solution, the first and second protrusions are staggered, ensuring that the fabric has protrusions in every row, both longitudinally and laterally. This improves the uniformity of the protrusion distribution, guaranteeing the uniformity of the fabric's elasticity and strength distribution, and reducing deformation caused by uneven local stress, thus enhancing the overall stability and durability of the fabric. Furthermore, when the fabric is stretched, the first and second protrusions work together more effectively to distribute stress, improving the overall elasticity and resilience of the fabric. In addition, this structure allows for a relatively flat area to be enclosed between adjacent first and second protrusions, enhancing the fabric's breathability and comfort to some extent.
[0014] Optionally, multiple second protrusions may be provided between two adjacent first protrusions in the same group.
[0015] By adopting the above technical solutions, the anti-slip performance is further enhanced, while the fabric surface becomes richer and more three-dimensional, increasing the fabric's aesthetic appeal.
[0016] Optionally, the first protrusion is hemispherical.
[0017] By adopting the above technical solution, the fabric has better anti-slip properties.
[0018] Optionally, the second protrusion is hemispherical.
[0019] By adopting the above technical solution, the fabric has better anti-slip properties.
[0020] Optionally, the smoothness of the second surface is greater than that of the first surface.
[0021] By adopting the above technical solution, when making the waistband, the rougher first side can be used as the outer surface. This reduces the amount of yarn used and lowers the difficulty of weaving the fabric while increasing the weaving efficiency.
[0022] Optionally, in the yarn, the nylon content is between 50% and 60%, and the spandex content is between 40% and 50%.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. Using a double-sided weft knitting machine, yarns made of nylon and spandex blends are knitted using a double-sided weft knitting method. After knitting, a first side and a second side are formed. During the knitting process, multiple first protrusions and multiple second protrusions are formed on the first side, so that the waistbands made from this fabric have good elasticity and good anti-slip performance.
[0025] 2. Both the first protrusion and the second protrusion are strip-shaped. The first protrusion extends laterally along the first surface, and multiple first protrusions are arranged at intervals along the first surface. The second protrusion extends longitudinally along the first surface, and multiple second protrusions are arranged at intervals along the first surface, ensuring the overall elasticity and resilience of the fabric, as well as the uniformity of the elasticity and strength distribution of the fabric.
[0026] 3. The yarn has a performance cavity inside to improve the breathability of the fabric. The performance cavity is reinforced with a reinforcing thread. The length of the reinforcing thread is greater than the length of the yarn, and the elasticity of the reinforcing thread is less than that of the yarn to prevent the fabric from deforming excessively and extend the service life of the fabric.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0033] This application discloses a nylon-spandex superelastic fabric.
[0034] Example 1
[0035] Reference Figure 1 and Figure 2 This application provides a nylon-spandex superelastic fabric, comprising a first surface 1 and a second surface 2. The first surface 1 and the second surface 2 are formed by weft knitting of yarn 3 using a double-sided weft knitting machine. The yarn 3 is a blend of nylon and spandex. The first surface 1 has multiple sets of first protrusions 11 and multiple sets of second protrusions 12. The multiple first protrusions 11 in each set are arranged at intervals along the transverse direction of the first surface 1, and the multiple second protrusions 12 in each set are also arranged at intervals along the transverse direction of the first surface 1. The multiple sets of second protrusions 12 and the multiple sets of first protrusions 11 are arranged at intervals along the longitudinal direction of the first surface 1.
[0036] Specifically, in this embodiment, the first protrusion 11 is strip-shaped and extends laterally along the first surface 1. The second protrusion 12 is strip-shaped and is arranged at intervals along the longitudinal direction of the first surface 1. It can be understood that the first protrusion 11 and the second protrusion 12 can be straight strips, wavy, or serrated.
[0037] Reference Figure 3 In this embodiment, the second protrusion 12 is formed as follows: each second protrusion 12 includes two component protrusions 13 arranged longitudinally at intervals along the first surface. The shape of each component protrusion 13 is the same as the shape of each first protrusion 11, and the extension direction is also the same. Using this method, the fabric can have different visual effects at different angles.
[0038] In other embodiments, multiple second protrusions 12 may be provided between two adjacent first protrusions 11 in the same group.
[0039] Reference Figure 4In this embodiment, the fabric is knitted using the method shown in the figure, where "⨆" represents gathering, "∨" represents forming a loop, and "—" represents translation. A cycle of 1-36 is formed. The double-sided weft knitting machine has two sets of needles and two sets of cam seat needle slots (the dividing lines in the figure distinguish the two sets of cam seat needle slots, namely the upper cam seat needle slot group and the lower cam seat needle slot group). One set of needles is installed in the upper cam seat needle slot group in a 1212 arrangement. The upper cam seat needle slot group has two sets of needle slot tracks, where 1 and 2 represent the needles installed in the corresponding needle slot groups. Similarly, one set of needles is installed in the lower cam seat needle slot group in a 1234 arrangement. The lower cam seat needle slot group has four sets of needle slot tracks, where 1, 2, 3, and 4 represent the needles installed in the corresponding needle slot groups. The above knitting method is common knowledge to those skilled in the art and will not be elaborated further here.
[0040] Furthermore, to improve anti-slip performance, a layer of tiny particles, such as polyester or nylon fibers, can be added to the surface of the second protrusion 12 to increase the coefficient of friction.
[0041] In this embodiment, the line connecting two adjacent groups of second protrusions 12 passes through the gap between adjacent first protrusions 11 in the same group, and multiple second protrusions 12 are arranged between two adjacent first protrusions 11 in the same group. This staggered arrangement design allows the entire fabric to better distribute pressure when under stress, reducing local stress concentration, thereby improving the durability and comfort of the fabric. At the same time, it can further enhance the three-dimensionality and layering of the fabric, and also help improve air circulation and enhance the wearing experience.
[0042] In other embodiments, the first protrusion 11 may also be hemispherical. A hemispherical first protrusion 11 can be more evenly distributed across the entire fabric surface, thus providing a more uniform anti-slip effect. Similarly, the second protrusion 12 is also spherical. Spherical protrusions not only increase the contact area but also effectively prevent wear caused by long-term friction.
[0043] In this embodiment, the smoothness of the second surface 2 is greater than that of the first surface 1, meaning that no weaving that could form protrusions is done on the second surface 2. When making the waistband, the relatively rough first surface 1 can be used as the outer surface, which consumes less yarn 3 and reduces the weaving difficulty and improves the weaving efficiency of the fabric.
[0044] In yarn 3, the nylon content is between 50% and 60%, and the spandex content is between 40% and 50%. Specifically, in this embodiment, the nylon content is 54%, and the spandex content is 46%. This ratio ensures sufficient elasticity while maintaining good abrasion resistance and wrinkle resistance. For example, nylon 66 and spandex Lycra can be selected as raw materials, both of which have excellent physical properties and are suitable for the production of high-end textiles.
[0045] The implementation principle of this embodiment is as follows: by using yarn 3 formed by blending nylon and spandex, and using a double-sided weft knitting machine to knit the first side 1 while knitting the second side 1, the first and second protrusions 11 and the second side 12 are knitted in an alternating manner, so that the waistband made of this fabric has good elasticity and high anti-slip performance.
[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
