Description

Technical Field

[0001] The utility model relates to the technical field of nylon yarn covering yarns, in particular to a tear-resistant high-adhesion nylon yarn covering yarn. Background Art

[0002] Nylon yarn, that is, filaments made of nylon fiber, is a synthetic fiber. Nylon yarn has many excellent properties, so it has been widely used in many fields. Nylon yarn has high strength and wear resistance, which makes it often used in the textile field to make durable clothing, such as sportswear, outdoor equipment, socks, etc. It can withstand frequent friction and stretching without being easily damaged. In the industrial field, nylon yarn can be used to make ropes, safety belts, fishing nets, cords, etc. Its high strength can meet the tension requirements of these products during use.

[0003] Although nylon covered yarn has a certain tear resistance, when it is subjected to high-intensity stress for a long time, tear propagation may gradually occur, leading to the ultimate failure of the material. Under the action of multi-directional and irregular stress, the tear resistance may not be as expected, and it is easy to tear at weak points. When the tear resistance deteriorates, the performance of the nylon yarn itself deteriorates. Then, over time, the adhesion may gradually decrease, especially when affected by environmental factors (such as temperature changes and chemical erosion). Utility Model Content

[0004] The utility model aims to solve the problem that the adhesion of nylon covering yarn will become poor after the tear resistance and expansion, and provides a tear-resistant nylon covering yarn with high adhesion.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] A tear-resistant high-adhesion nylon yarn-covered yarn comprises a nylon body, a modified polymer is arranged on the outside of the nylon body, a polyester fiber penetrates the outside of the modified polymer, the inside of the modified polymer is annularly wrapped around the outside of the nylon body, the inside of the polyester fiber is annularly wrapped around the outside of the modified polymer, nano silver wires are mixed in the polyester fiber, the side wall surface of the polyester fiber has tiny plush, and a self-repairing polymer is added to the fine plush on the inside of the polyester fiber.

[0007] Furthermore, the nylon body, the modified polymer and the polyester fiber are interwoven with each other, suitable nylon body, modified polymer and polyester fiber yarns are selected, and inspection, warping and other treatments are carried out, the yarns are installed on the weaving equipment, and the nylon body is used for weaving the bottom layer. The nylon body has the characteristics of good wear resistance and high strength, and serves as the basic structure and support.

[0008] Furthermore, a polymer coating is provided on the surface of the nylon body, and the modified polymer covers the outer wall of the nylon body wrapped with the coating. The polymer coating can increase the surface hardness and wear resistance of the nylon body, making it more durable, and can prevent chemical substances from corroding the nylon body and improve its corrosion resistance. Adding a layer of modified polymer on the basis of the existing coating can provide additional protection.

[0009] Furthermore, the nylon body and the polyester fibers are connected together by twisting, and the nylon body and the polyester fibers are interwoven and interlaced with each other.

[0010] Compared with the prior art, the utility model provides a tear-resistant high-adhesion nylon yarn covering yarn, which has the following beneficial effects:

[0011] The tear-resistant high-adhesion nylon yarn-covered yarn is prepared by mixing nano-silver wire into polyester fiber. The nano-silver wire is added to the polyester fiber to improve the strength, toughness and thermal stability of the polyester fiber. The side wall surface of the polyester fiber has tiny plush, and the fine plush on the inside of the polyester fiber is added with a self-repairing polymer. When the entire wire is bent or shaped into various shapes, when cracks appear on the side wall of the entire wire, the self-repairing polymer added to the inner holes of the plush on the side wall surface of the polyester fiber can seep outward along the side wall of the polyester fiber, and the cracks on the side wall of the entire nylon yarn-covered yarn can be quickly repaired, thereby improving the bonding performance.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1:

[0016] like Figure 1-Figure 2As shown, a tear-resistant high-adhesion nylon yarn-covered yarn comprises a nylon body 1, a modified polymer 2 is arranged on the outside of the nylon body 1, a polyester fiber 3 is penetrated on the outside of the modified polymer 2, the inside of the modified polymer 2 is annularly wrapped around the outside of the nylon body 1, the inside of the polyester fiber 3 is annularly wrapped on the outside of the modified polymer 2, nano silver wires are mixed in the polyester fiber 3, and the nano silver wires are added to the polyester fiber 3 to improve the strength, toughness and thermal stability of the polyester fiber 3, and there are tiny plush on the side wall surface of the polyester fiber 3, and self-repairing polymers are added to the fine plush on the inside of the polyester fiber 3. When the entire nylon body 1, the modified polymer 2 and the polyester fiber 3 are combined together to form a line, when the entire line is bent or various shapes, then when the side wall of the entire line is bent and cracks appear, the self-repairing polymer added in the inner hole of the plush on the side wall surface of the polyester fiber 3 can seep outward along the side wall of the polyester fiber 3, and the cracks on the side wall of the entire nylon yarn-covered yarn can be quickly repaired, and the bonding performance can be improved. Embodiment 2:

[0017] like Figure 1-Figure 2 As shown, nylon body 1, modified polymer 2 and polyester fiber 3 are interwoven with each other, suitable nylon body 1, modified polymer 2 and polyester fiber 3 yarns are selected, and inspection, warping and other treatments are carried out, the yarns are installed on the weaving equipment, and nylon body 1 is used for weaving the bottom layer. Nylon body 1 has the characteristics of good wear resistance and high strength, and serves as the basic structure and support;

[0018] On the basis of the nylon body 1 woven at the bottom layer, a modified polymer 2 is added to weave the middle layer. The modified polymer 2 can improve the performance of the nylon body 1 and increase its softness and elasticity.

[0019] Finally, polyester fiber 3 is used to weave the surface of the outer layer of modified polymer 2, and self-repairing polymer is added during the weaving process to improve wrinkle resistance and shape retention.

[0020] like Figure 1-Figure 2 As shown, the surface of the nylon body 1 is provided with a polymer coating, and the modified polymer 2 covers the outer side wall of the nylon body 1 wrapped with the coating. The polymer coating can increase the surface hardness and wear resistance of the nylon body 1, making it more durable, and can prevent the erosion of the nylon body 1 by chemical substances, thereby improving its corrosion resistance. Adding a layer of modified polymer 2 on the basis of the existing coating can provide additional protection. The modified polymer 2 may have specific mechanical properties, such as higher flexibility or tensile strength, thereby compensating for the mechanical deficiencies of the nylon body 1 and the original coating, making the overall structure more able to withstand external forces, and facilitating the combination of the nylon body 1 with other materials or components, thereby improving the compatibility and connection strength of the interface;

[0021] like Figure 1-Figure 2As shown, the nylon body 1 and the polyester fiber 3 are connected together by twisting. In this process, a special twisting device plays a key role. First, the nylon body 1 and the polyester fiber 3 are placed in specific positions of the device respectively. After the device is started, the two fibers are gradually pulled closer and in contact through rotation and stretching. Then, the force of rotation drives the two fibers to begin to entangle around each other. During twisting, the fibers are subjected to a certain tension, which makes them fit more closely during the winding process. As the twisting continues, the nylon body 1 and the polyester fiber 3 are intertwined and interspersed with each other. This twisting method combines the advantages of the two fibers. The high strength and wear resistance of the nylon body 1 and the good elasticity and wrinkle resistance of the polyester fiber 3 complement each other, so that the connected fiber combination has better comprehensive performance.
