[0002] In many occasions, especially in engineering construction, some fabrics with anti-slip effects are often needed to increase friction and ensure that users do not slip when applying force. The existing conventional way to increase the friction of the fabric surface is to coat the surface of the fabric with a layer of rubber bumps. However, the rubber bumps that are adhered are easy to fall off, resulting in a decrease in the surface friction coefficient of the fabric.
[0003] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0015] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0016] Example: A non-slip polyester fabric, such as Figure 1 As shown, it includes a base layer, which includes a first weft yarn 1, a second weft yarn 2, a first warp yarn 3 and a second warp yarn 4. The diameter of the first warp yarn 3 is greater than the diameter of the second warp yarn 4, the diameter of the first weft yarn 1 is greater than the diameter of the second weft yarn 2, the first weft yarn 1 and the second weft yarn 2 are alternately arranged in the warp direction at a fixed ratio, the density of the first weft yarn 1 is less than the density of the second weft yarn 2, the first warp yarn 3 and the second warp yarn 4 are alternately arranged in the weft direction at a fixed ratio, and the density of the first warp yarn 3 is less than the density of the second warp yarn 4.
[0017] Specifically, the diameter of the first warp yarn 3 is the same as the diameter of the second weft yarn 2, the diameter of the second warp yarn 4 is the same as the diameter of the second weft yarn 2, the diameter of the first warp yarn 3 is twice the diameter of the second warp yarn 4, and the thickness of the overlapping part of the first warp yarn 3 and the second weft yarn 2 is greater than that of the overlapping part of the second warp yarn 4 and the second weft yarn 2, which is manifested as a convex point protruding outward at the overlapping part of the first warp yarn 3 and the first weft yarn 1.
[0018] Through the diameter difference between the first warp yarn 3, the first weft yarn 1 and the second warp yarn 4, the second weft yarn 2, a number of convex points are woven into the fabric, which increases the friction coefficient of the fabric surface and prevents slipping. The second weft yarn 2 and the second warp yarn 4 have a large density, which highlights the convex point structure. Because it is the woven structure of the fabric itself, it will not fall off and has high strength.
[0019] like Figure 1 As shown, one first weft yarn 1 and four second weft yarns 2 form a weft yarn cycle, and a weft gap is formed between adjacent weft yarn cycles. One first warp yarn 3 and four second warp yarns 4 form a warp yarn cycle, and a warp gap is formed between adjacent warp yarn cycles. The first warp yarn 3 and the first weft yarn 1 form a first plain weave, and the second weft yarn 2 and the second warp yarn 4 form a second plain weave. The overlapping parts of the first weft yarn 1 and the first warp yarn 3 float on the same side of the second plain weave.
[0020] Specifically, on the side of the fabric where the convex points are formed, when the first warp yarn 3 passes through a group of weft yarn cycles, along the length direction of the first warp yarn 3, the first warp yarn 3 floats, sinks, sinks, and floats relative to the second weft yarn 2 in sequence. When the first weft yarn 1 passes through a group of warp yarn cycles, along the length direction of the first weft yarn 1, the first weft yarn 1 floats, sinks, sinks, and floats relative to the second warp yarn 4 in sequence. By controlling the arrangement of the weft yarns and the feeding interval of the warp yarns, weft gaps and warp gaps are formed between the warp yarn cycles and the weft yarn cycles respectively.
[0021] The plain weave makes the sink-float ratio of the fabric tend to 1, that is, the interweaving points are increased, the connection strength between the yarns is improved, and the yarns are prevented from shifting and falling off. The difference between the maximum thickness and the minimum thickness on the fabric is increased through the warp and weft gaps, and the friction coefficient of the fabric surface is further increased. The convex points are floated on the same side of the fabric, which increases the friction coefficient of one side of the fabric.
[0022] like Figure 2 As shown, the second warp yarn 4 and the second weft yarn 2 are both made of elastic yarn, and the first warp yarn 3 and the first weft yarn 1 are both made of wear-resistant yarn. A number of grooves are formed on the surface of the wear-resistant yarn. The wear-resistant yarn is composed of a polyester fiber bundle 5 and a shaped nylon fiber bundle 6 wrapped around the polyester fiber bundle 5. The elastic yarn is twisted by a T400 fiber bundle, and the shaped nylon fiber bundle 6 is twisted by a shaped nylon fiber yarn with a Y-shaped cross-section.
[0023] Specifically, the elastic yarn is formed by twisting two T400 fiber bundles, the shaped nylon fiber bundle 6 is formed by twisting two shaped nylon fiber strands with a Y-shaped cross-section, the shaped nylon fiber strands are extruded from a spinneret with a Y-shaped cross-section, and the wear-resistant yarn is formed by winding a single shaped nylon fiber bundle 6 around a single polyester fiber bundle 5.
[0024] The good elasticity of the T400 fiber bundle is used to improve the elasticity of the stretch yarn, and the elastic deformation of the stretch yarn is used to improve the clamping force of the second weft yarn 2 and the second warp yarn 4 on the first weft yarn 1 and the first warp yarn 3. The shaped nylon fiber bundle 6 has good wear resistance, which improves the service life of the wear-resistant yarn. The shaped nylon fiber yarn with a Y-shaped cross-section forms grooves on the surface of the wear-resistant yarn, thereby improving the friction coefficient of the wear-resistant yarn surface.
[0025] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
