Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of nylon fabrics, and in particular relates to a wear-resistant and tear-resistant nylon fabric and a processing method thereof. Background Art
[0002] Nylon fabrics are widely used in many fields due to their excellent strength and wear resistance. However, in some specialized industries with extremely high requirements for wear and tear resistance, such as outdoor sports equipment, industrial protective clothing, and military equipment, the performance of ordinary nylon fabrics still cannot meet actual use needs.
[0003] In response to the problem of insufficient wear resistance and tear resistance of nylon fabrics, researchers have proposed a variety of modification methods. For example, by increasing the twist of the yarn, adopting a high-density weaving process or increasing the thickness of the fabric, its wear resistance can be improved to a certain extent. However, these methods often cause the fabric to feel harder and its breathability to decrease, affecting wearing comfort. In addition, some companies use coating or impregnation processes to form a wear-resistant protective layer on the surface of the fabric, such as polyurethane (PU) coating, polytetrafluoroethylene (PTFE) coating, etc. Although these coatings can enhance the wear resistance of the fabric to a certain extent, their durability is limited. They are easy to peel off after multiple washings or long-term use, affecting the long-term performance of the fabric.
[0004] For example, patent application publication number CN115897225A discloses a high-strength, wear-resistant nylon fabric and its preparation process. The process comprises the following steps: first, preparing a modified nylon fiber containing nylon, a black masterbatch, and a transition metal salt; then, blending and twisting the modified nylon fiber with other fiber materials to form a grey fabric; and finally, cleaning, impregnating, and drying the fabric to form the nylon fabric. By adding the modified nylon fiber to the nylon fabric, the resulting nylon fabric possesses the characteristics of the modified nylon fiber, resulting in enhanced wear resistance.
[0005] For example, the patent application document with application publication number CN118422369A discloses an antibacterial and wear-resistant nylon fiber and a preparation method thereof. By adding composite fillers to the raw materials for preparing the nylon fiber and coating the outside of the fiber with a coating made of a composite finishing agent as raw material, the nylon fiber has good antibacterial and wear-resistant properties; the cross-linked network formed by the composite finishing agent is combined with the rigid group, and it also contains a structure that undergoes self-repairing behavior under ultraviolet irradiation, so that the coating formed by it has good wear resistance, and because the coating and the fiber are connected by a strong chemical bond, the coating is prevented from falling off.
[0006] While existing technologies have improved the wear resistance of nylon fabrics to some extent, they still face numerous limitations. First, many modification methods improve performance while sacrificing comfort and lightness, making them difficult to meet the demands of the high-end textile market. Second, some modification processes rely on high-cost materials or complex processing steps, limiting their large-scale application. Therefore, developing a nylon fabric that maintains its inherent excellent properties while significantly improving its wear and tear resistance is of great significance. Summary of the Invention
[0007] In view of the above problems, in order to further improve the wear resistance of nylon fabric and meet specific application environments, the present application provides a wear-resistant and tear-resistant nylon fabric and a processing method thereof.
[0008] The present application first provides a wear-resistant and tear-resistant nylon fabric, including a fabric base and a wear-resistant coating arranged on the surface of the fabric base; the fabric base is made of raw materials including the following parts by weight: 85-95 parts of nylon masterbatch, 2-5 parts of graphene, 1-3 parts of silicon carbide, 0.5-1.5 parts of coupling agent, 0.2-0.5 parts of antioxidant, and 0.3-0.8 parts of lubricant; the wear-resistant coating includes a resin adhesive and a wear-resistant filler.
[0009] Furthermore, the resin adhesive is one of polyvinyl chloride, polyvinyl alcohol, polyethylene, epoxy resin, and polyurethane.
[0010] Furthermore, the wear-resistant filler is prepared by the following steps:
[0011] 1) After alkali leaching and acid washing, the cellulose is crushed and ground to obtain an intermediate material;
[0012] 2) zirconium tetrachloride, 2-aminoterephthalic acid, intermediate material and solvent are mixed evenly, sealed for reaction, washed, dried, roasted and ground to obtain the product.
[0013] Furthermore, the mass ratio of the zirconium tetrachloride to the intermediate material is 1:(1.5-2).
[0014] Furthermore, the average particle size of the wear-resistant filler is 200-350 nm.
[0015] The present application also provides a process for processing wear-resistant and tear-resistant nylon fabric, comprising the following steps:
[0016] S1: Weigh nylon masterbatch, graphene, silicon carbide, coupling agent, antioxidant, and lubricant in proportion, mix them evenly, melt-spin to obtain fiber material, and weave the fiber material to obtain a fabric matrix;
[0017] S2: placing the fabric substrate in the impregnation liquid for impregnation treatment, taking it out and drying it for later use;
[0018] S3: taking a resin adhesive and a wear-resistant filler and mixing them evenly to obtain a modifying liquid, then padding the impregnated fabric substrate in the modifying liquid, and drying and solidifying it to obtain the fabric substrate, which is prepared by the above-mentioned preparation method.
[0019] Furthermore, the impregnation solution includes water, organic acid and divalent metal salt.
[0020] Furthermore, the divalent metal salt is one or more of calcium chloride, copper chloride, and zinc chloride.
[0021] Furthermore, the concentration of the divalent metal salt in the impregnation solution is 2-5 wt %.
[0022] Furthermore, the organic acid is at least one of formic acid, acetic acid, and hydroxyproline.
[0023] Compared with the prior art, this application has the following beneficial effects:
[0024] 1. This application uses nylon masterbatch and graphene, silicon carbide and other components for mixed melt spinning. The resulting fiber material has better wear resistance and surface adhesion. On the one hand, it improves the overall wear resistance of the fabric. On the other hand, it also enhances the bonding force between the wear-resistant coating and the fabric matrix, improving the problem of subsequent peeling and shedding of the coating due to factors such as use and washing.
[0025] 2. After the fabric substrate of the present application is treated with the impregnation liquid, the metal ions can undergo complexation with the amide groups on the fiber surface, which can increase the number of polar groups and specific surface area on the fabric fiber surface, and further enhance the interfacial bonding strength between the wear-resistant coating and the fabric.
[0026] 3. The wear-resistant coating of the present application is composed of a resin binder and a wear-resistant filler. The wear-resistant filler uses cellulose as a carrier. Then, zirconium ions react with 2-aminoterephthalic acid in the carrier to form a porous organic material. After calcination, it can form toughened porous particles, which can form an anisotropic dispersion system in the wear-resistant coating, thereby improving the crosslinking density and adhesion of the wear-resistant coating. In addition, the introduction of the wear-resistant filler can effectively anchor the coating. The porous structure of the wear-resistant filler can limit the movement of the surrounding resin binder macromolecules, reduce the friction loss of the wear-resistant coating, and thus improve the wear resistance of the fabric.
