Description

Technical Field

[0001] This utility model relates to the field of artificial leather technology, specifically to a composite artificial leather. Background Technology

[0002] In daily life, leather is widely loved by consumers, and leather-made basketballs, bags, shoes, and clothing occupy a large market share. Due to increasing market demand, traditional raw hides can no longer meet people's needs, thus artificial leather has emerged as an alternative material. Artificial leather is a plastic product that resembles leather in appearance and feel and can be used as a substitute. It mainly includes two types: PVC artificial leather and PU synthetic leather.

[0003] Currently, existing artificial leather is usually made by coating synthetic resin and various plastic additives with fabric as the base. When used as a seat cushion, the fabric base is relatively smooth and has a low coefficient of friction, so it is easy to slip and the performance is not good. Utility Model Content

[0004] The purpose of this invention is to provide a composite artificial leather to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a composite artificial leather, comprising a surface layer and a base layer, wherein a plurality of anti-slip yarns are interwoven and connected on the base layer, and the portion of the anti-slip yarns that extends through the lower surface of the base layer forms a plurality of anti-slip protrusions, wherein the anti-slip yarns are formed by two strands of slivers wound alternately, and a plurality of knots are formed on the anti-slip yarns.

[0006] As a further feature of this invention, the sliver is made of several twisted nylon fibers.

[0007] As a further feature of this invention, a connecting section is provided between adjacent anti-slip protrusions, and the connecting section is bonded between the base layer and the surface layer by hot melt adhesive.

[0008] As a further feature of this invention, the base layer is made of several textile yarns woven in a weft pattern.

[0009] As a further feature of this invention, the textile yarn includes a core and a covering yarn spirally wound around the outside of the core. The covering yarn is formed by spirally twisting a first winding and a second winding. The first winding is formed by twisting several viscose fibers, and the second winding is formed by twisting several bamboo charcoal fibers.

[0010] As a further feature of this invention, the core is made of several twisted polyester fibers.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention features anti-slip protrusions that extend beyond the lower surface of the base layer, collectively forming an anti-slip surface. This significantly increases the coefficient of friction on the lower surface of the base layer. Furthermore, the presence of multiple knots in the anti-slip yarns further enhances their friction coefficient and anti-slip capability. Consequently, when artificial leather is used as a seat cushion, the anti-slip surface can serve as the bottom surface, providing a superior anti-slip effect and preventing the artificial leather from slipping, resulting in a better overall performance.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 , Figure 2As shown, a composite artificial leather includes a surface layer 1 and a base layer 2. Several anti-slip yarns are interwoven and connected on the base layer 2, and the portions of the anti-slip yarns extending beyond the lower surface of the base layer 2 form several anti-slip protrusions 3. The anti-slip yarns are slub yarns, formed by two strands of yarn wound alternately, and several knots 4 are formed on the anti-slip yarns. Because the anti-slip protrusions 3 extend beyond the lower surface of the base layer 2, they collectively form an anti-slip surface, thereby greatly increasing the coefficient of friction of the lower surface of the base layer 2. Furthermore, the presence of multiple knots 4 on the anti-slip yarns further enhances the coefficient of friction of the anti-slip yarns, thus strengthening the anti-slip properties. The anti-slip ability of the yarn allows the anti-slip surface to serve as the bottom surface when the artificial leather is used as a seat cushion, providing a good anti-slip effect and preventing the artificial leather from slipping. The yarn is made of several twisted nylon fibers, which have high abrasion resistance, making the surface of the anti-slip yarn wear-resistant and not easy to break. A connecting section 5 is provided between adjacent anti-slip protrusions 3, and the connecting section 5 is bonded between the base layer 2 and the surface layer 1 with hot melt adhesive. By bonding the connecting section 5 between the base layer 2 and the surface layer 1, the anti-slip yarn can be prevented from coming loose, ensuring the firm connection of the anti-slip yarn on the artificial leather.

[0019] Please see Figure 3 As shown, the base layer 2 is made of several textile yarns weft-knitted together. The weft-knitting method gives the base layer 2 good elasticity and toughness, thus giving the artificial leather good extensibility. The textile yarns include the core 6 and the covering yarn spirally wound around the outside of the core 6. The core 6 is made of several polyester fibers twisted together, which has good strength and toughness, thus ensuring the tensile strength of the artificial leather. The covering yarn is made of the first winding yarn 7 and the second winding yarn 8 spirally twisted together. The first winding yarn 7 is made of several viscose fibers twisted together, and the second winding yarn 8 is made of several bamboo charcoal fibers twisted together. The viscose fibers have high moisture absorption, thus giving the artificial leather good moisture absorption effect. The bamboo charcoal fibers have good antibacterial and deodorizing effects, which can prevent the artificial leather from growing bacteria and prevent the artificial leather from producing odor.
