Description

Technical Field

[0001] This utility model relates to the field of knitted fabric technology, specifically to a wear-resistant polyester fabric. Background Technology

[0002] Knitted fabric, as a common textile, is widely used in clothing, home textiles and industrial textiles. It is made of interlocking loops and has a certain degree of softness and extensibility. Polyester fiber is often used as the main raw material for knitted fabric due to its advantages such as high strength, good heat resistance and moderate cost. Polyester-cotton blended fabrics combine the durability of polyester with the comfort of cotton and have become a common choice in the market.

[0003] In practical use, knitted fabrics, especially polyester fabrics used to make work clothes, sportswear, furniture upholstery materials, etc., will inevitably rub against external objects frequently. In order to improve the abrasion resistance of the fabric, existing technologies usually choose to increase the fabric weight and use higher strength fibers. However, increasing the weight will make the fabric harder and heavier, affecting comfort and flexibility. Using high-strength fibers may sacrifice the feel and cost advantage.

[0004] More importantly, when friction occurs, the traditional dense fabric structure lacks an effective buffering mechanism. The frictional stress will directly act on the local fibers, causing them to wear out quickly because they cannot disperse and absorb energy through sufficient elastic deformation. Therefore, it can be seen that the durability of polyester fabrics in the current technology is often unsatisfactory when faced with continuous or severe friction, and the service life is thus shortened. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art by proposing a wear-resistant polyester fabric.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a wear-resistant polyester fabric, comprising a layered composite fabric body, wherein the fabric body includes: A wear-resistant layer, wherein a plurality of slits are arranged in an array on the wear-resistant layer, and a plurality of connecting strips are formed in the areas of the wear-resistant layer where no slits are provided; A deformation layer is stacked below the wear-resistant layer. The deformation layer has several strip-shaped curved portions that protrude at intervals on the side facing the wear-resistant layer. The connecting strip is fixedly bonded to the two sides of the top of the curved portion by an adhesive portion provided on its lower surface, so that the wear-resistant layer and the deformation layer form a hollow air layer between adjacent connecting strips. A skin-friendly layer is stacked on the side of the deformation layer facing away from the wear-resistant layer.

[0007] The present invention is further configured such that: a plurality of guide strips are fixedly bonded to the deformation layer in the area corresponding to the air layer, and the guide strips are bonded between adjacent curved portions.

[0008] The present invention is further configured such that: the deformation layer has openings that penetrate its thickness between adjacent guide strips.

[0009] The present invention is further configured such that the adhesive portion is a hot melt adhesive bonding point formed by a hot pressing process.

[0010] The present invention is further configured such that the guide strip is a flexible silicone strip.

[0011] The present invention is further configured such that the deformation layer is woven from rubber filaments.

[0012] The present invention is further configured such that both the wear-resistant layer and the skin-friendly layer are knitted polyester-cotton blended fabrics.

[0013] The present invention is further configured such that: the opening is elongated, and a plurality of the openings are arranged at intervals along the length direction of the air layer.

[0014] In summary, this utility model has the following beneficial effects: by setting a wear-resistant layer with a cut, an elastic deformation layer with a pre-formed curved part, and an air layer formed between the two, the fabric friction is converted into elastic deformation, which significantly disperses and absorbs frictional stress, thereby fundamentally improving the wear resistance of polyester fabric without significantly increasing the fabric weight and hardness.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] A type of abrasion-resistant polyester fabric, such as Figure 1 as well as Figure 2 As shown, the fabric is a layered composite fabric, which includes, from the outside to the inside, a wear-resistant layer 1, a deformation layer 2, and a skin-friendly layer 3. The wear-resistant layer 1 is made of a knitted polyester-cotton blended fabric. Several long and thin slits 11 are arranged in an array by cutting. These slits 11 divide the wear-resistant layer 1 into multiple areas. In the areas where no slits 11 are provided, the fabric remains intact and forms several connecting strips. The bottom surface of the connecting strip, that is, the side facing the deformation layer 2, is provided with a hot melt adhesive material 12 by hot pressing process. The deformation layer 2 is stacked below the wear-resistant layer 1. In this embodiment, the deformation layer 2 is woven from rubber filaments, which gives the deformation layer 2 good elasticity. The side of the deformation layer 2 facing the wear-resistant layer 1 is formed with several strip-shaped curved parts 21 through a hot bending and shaping process. The connecting strip on the wear-resistant layer 1 is fixedly bonded to the two sides of the top of the curved part 21 through the adhesive part 12 on its bottom surface. This bonding method makes a hollow strip-shaped air layer 5 formed between the wear-resistant layer 1 and the deformation layer 2 between the adjacent connecting strips. Furthermore, in the area corresponding to the air layer 5 on the deformable layer 2, several flexible silicone guide strips 4 are fixedly bonded. These guide strips 4 are bonded between adjacent curved portions 21. At the same time, on the deformable layer 2, between adjacent guide strips 4, there are also elongated openings 22 that penetrate their thickness. Several openings 22 are arranged along the length direction of the air layer 5. The skin-friendly layer 3 is stacked on the side of the deformation layer 2 facing away from the abrasion-resistant layer 1. In this embodiment, a knitted polyester-cotton blended fabric is also used to provide a comfortable skin-friendly experience.

[0019] Usage: When polyester fabric is made into workwear, sportswear or furniture covering material and put into use, when its abrasion layer 1 rubs against external objects and is subjected to pressure, the pressure first acts on the abrasion layer 1. The cut 11 on the abrasion layer 1 allows the abrasion layer 1 to undergo local deformation. The pressure is then transmitted to the top two sides of the curved part 21 of the deformation layer 2 through several connecting strips and adhesive parts 12. The curved part 21 undergoes elastic compression under pressure. The air layer 5 below it provides sufficient clearance for the abrasion layer 1 to sink. The guide strip 4 ensures that the deformation of adjacent curved parts 21 is synchronous and controllable. During this process, the frictional energy is effectively absorbed and dispersed by the elastic deformation of the curved part 21. The opening 22 on the deformation layer 2 also assists in this deformation process and avoids stress concentration. After the pressure is released, the structure of each layer returns to its original shape under the action of elasticity.

[0020] Beneficial effects: By setting up an abrasion-resistant layer 1 with a cut 11, an elastic deformation layer 2 with a pre-formed curved part 21, and an air layer 5 formed between the two, the friction of the fabric is converted into elastic deformation, which significantly disperses and absorbs frictional stress. Thus, without significantly increasing the fabric weight and hardness, the abrasion resistance of the polyester fabric is fundamentally improved, its service life is extended, and the original comfort and flexibility of the fabric are maintained.
