Sportswear worn during exercise usually uses ribbons to make it more suitable for exercise. The ribbon used in sportswear needs to have a one-way moisture conduction and moisture absorption and quick drying effect, so as to improve its wearing comfort. However, the existing one-way moisture conduction ribbon is usually used by using one side for hydrophilic treatment and one side for hydrophobic material. The process is more complicated and difficult in subsequent production, and the moisture absorption rate is low. It cannot absorb the moisture of the skin and conduct it to the outside in time, so that the water content on the side close to the skin increases, and it will adhere to the skin, and the wearing comfort is poor. How to prepare a one-way moisture conduction, moisture absorption and quick drying ribbon that can quickly conduct moisture has become a problem to be solved. Summary of the invention

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Embodiment 1

[0027] Combination Figure 1 , Figure 2 , this embodiment is described in detail. This embodiment involves a production process for a unidirectional moisture-conducting, moisture-absorbing and quick-drying webbing, wherein the prepared webbing includes a webbing body formed by interweaving warp yarns and weft yarns, wherein the warp yarns include a first warp yarn 11 and a second warp yarn 12; the elasticity of the first warp yarn 11 and the weft yarn 13 is less than the elasticity of the second warp yarn 12; the first warp yarn 11 is nylon DTY filament, and the weft yarn is nylon FDY filament; the webbing body includes an arc-shaped portion 1 formed by interweaving the first warp yarn 11 and the weft yarn 13, and an elastic yarn layer 2 formed by the second weft yarn 12, and there is a cavity 3 between the arc-shaped portion 1 and the elastic yarn layer 2.

[0028] The production process includes the following steps: S1 warping, S2 drawing-in, S3 weaving, S4 raising and S5 finishing. In the warping process, the first warp yarn 11 and the second warp yarn 12 are warped on the first weaving beam and the second weaving beam respectively; this is because the first warp yarn 11 and the second warp yarn 12 have different elasticities.

[0029] The first warp yarn and the second warp yarn are drawn in the order of 1:1; the first warp yarn 11 and the weft yarn 13 are interwoven in a plain weave, and the second warp yarn 13 and the weft yarn are interwoven in an M-upper-N-lower weave, where M and N are both integers greater than or equal to 2. The prepared ribbon fabric is then raised and finished.

[0030] Since the first warp yarn 11 and the weft yarn 13 are interwoven in plain weave to form the base fabric, and the second warp yarn 12 and the weft yarn 13 are interwoven in M-upper-N-lower weave, the warp float length formed by the second warp yarn 12 is longer than the warp float length formed by the first warp yarn 11, and the elasticity of the second warp yarn 12 is greater than the elasticity of the first warp yarn 11, the second warp yarn 12 will shrink in the formed webbing, so that the fabric formed by the interweaving of the first warp yarn 11 and the weft yarn 13 will be arched or sunken, and the second warp yarn 12 will form a parallel elastic yarn layer 2 at the arched or sunken position. Thus, the webbing forms an arc portion 1 and an elastic yarn layer 2, and a cavity 3 is formed between them. The first warp yarn 11 and the weft yarn 13 are interwoven with conventional nylon or polyester filaments, so that the yarns of the base fabric will not increase the warp density and weft density due to the shrinkage of the elastic yarn. If the spacing between the yarns is small, the infiltration of the liquid will be weakened. In the present invention, the sweat secreted by the human skin will pass through the arc portion 1 formed by the base fabric and seep into the elastic yarn layer 3 through the cavity 3. The elastic yarn layer 3 is a warp floating long line formed by the second warp yarn 12, which can make the sweat easily diffuse along the direction of the elastic yarn layer 3 and increase its diversion and diffusion speed.

[0031] Further, the second warp yarn 12 and the weft yarn 13 are interwoven in a three-up-three-down or four-up-four-down weave. In this embodiment, a four-up-four-down twill weave is selected, that is, in this embodiment, both M and N are selected as 4. Of course, other values ​​can also be selected according to actual needs, such as three-up-four-down, two-up-three-down, or five-up-five-down.

[0032] Further, the first warp yarn 11 is nylon 6DTY filament, and the weft yarn is nylon 6FDY filament. The second warp yarn 12 is an elastic filament or elastic core-spun yarn with good elasticity. If it is an elastic filament, it can be spandex filament, T400 elastic filament or T800 elastic filament. If it is an elastic core-spun yarn, it includes elastic filament and nylon long thread or chemical fiber filament covering the outside of the elastic filament. In this embodiment, nylon elastic core-spun yarn is selected, and the nylon elastic core-spun yarn includes core yarn and covering yarn, the core yarn is elastic filament, and the covering yarn is nylon filament. The elastic filament used is spandex filament, and the fineness of the spandex filament can be selected according to actual needs. In this embodiment, 40D is selected. The nylon filament coated on the outside of the spandex filament is 40D / 24F nylon 6DTY filament.

[0033] Further, in this embodiment, the first warp yarn 11 and the weft yarn 13 are selected to be 70D / 24F. Of course, the fineness of the first warp yarn 11 and the weft yarn 13 can also be selected according to actual needs. Further, the nylon FDY filament is flat. The surface density of the woven ribbon can be selected according to actual needs, and in this embodiment, it is about 320 grams per square meter.

[0034] The post-finishing is to immerse the raised webbing in a moisture-absorbing and quick-drying finishing liquid, then dry and heat-set, with a rolling rate of 70-80%; the moisture-absorbing and quick-drying finishing liquid includes a moisture-absorbing and perspiration-releasing finishing agent, a hydrophilic polyurethane polymer, a fatty alcohol polyether amide and water, and a pH value adjusting agent adjusts the pH value of the moisture-absorbing and quick-drying finishing liquid to 4.5-5.0. The moisture-absorbing and perspiration-releasing finishing agent used is Richperm NPU liq, and of course other moisture-absorbing and perspiration-releasing finishing agents can be selected according to actual needs, which can be applicable to nylon 6 fiber.

[0035] The moisture wicking finishing agent used is a moisture wicking finishing agent. In the moisture wicking quick-drying finishing liquid, the content of the moisture wicking finishing agent is 10-30 g / L, the amount of the hydrophilic polyurethane polymer is 3-5 g / L, and the amount of the fatty alcohol polyether amide is 5-8 g / L.

[0036] Specifically in this embodiment, the content of the moisture wicking finishing agent is 20 g / L, the amount of the hydrophilic polyurethane polymer is 4 g / L, the amount of the fatty alcohol polyether amide is 7 g / L, and the pH value is adjusted to 5.0. Heat setting means that the padding ribbon is first dried at 80-85°C until the ribbon has a moisture content of about 10%, and then dried at 50-55°C.

[0037] The webbing involved in the comparative example uses nylon spandex core-spun yarn as the warp yarn and nylon DTY filament as the weft yarn, and has the same gram weight as the webbing prepared by the present invention and has undergone the same moisture absorption and perspiration wicking finishing.

[0038] The comparative ribbon is usually made of elastic warp yarn and weft yarn interwoven in a plain weave. Since the warp yarn is elastic, the weft density increases when it contracts, which increases the tightness of the ribbon, thereby reducing the gaps between the yarns, making it difficult for moisture attached to the surface to penetrate.

[0039] The warp yarns in the webbing prepared by the present invention include a first warp yarn and a second warp yarn with different elasticity, and the second warp yarn with higher elasticity has a longer floating line when interlaced with the weft yarn. When the second yarn contracts, the interlaced part of the first warp yarn and the weft yarn will be arched, while the distance between the first warp yarn and the weft yarn will not decrease, and the penetration of moisture will not be affected.

[0040] After moisture wicking finishing, the moisture wicking finishing agent will penetrate into the interior of the fabric, but the conventional webbing has a small spacing between yarns, making it difficult for the moisture wicking finishing agent to penetrate into the webbing. The fabric will shrink after washing, but the spacing between yarns of conventional webbing will become smaller after washing, and the moisture wicking finishing agent will mostly adhere to the surface of the webbing, which greatly reduces the moisture wicking and moisture absorption rate of conventional webbing after washing.

[0041] The unidirectional moisture-conducting, moisture-absorbing and quick-drying webbing prepared by the present invention was tested for moisture absorption and perspiration. The test standard is GB / T21655.2-2019 "Evaluation of moisture absorption and quick-drying properties Part 2: Dynamic moisture transfer method". The specific results are as follows:

[0042]

[0043]

[0044] In addition, the one-way moisture-conducting, moisture-absorbing and quick-drying webbing prepared by the present invention has its weft yarn expanded after moisture absorption, thereby increasing the width of the webbing by about 1 mm.

[0045] exist Figures 3 to 6 In the figure, the left side is the webbing prepared by the present invention, and the right side is the comparative example. Figures 3 to 6 It can be seen from the comparison that the webbing prepared by the present invention has a good moisture absorption and quick drying effect. And it still has a good moisture absorption and quick drying effect after washing.

[0046] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
