Problems solved by technology

To sum up, in the prior art, the new functions of socks are usually achieved through an additional material layer or coating, but the addition or adhesion of a silicone sheet or gel layer is caused by the fact that it is not integrated with the sock material itself. Discomfort to the feet, and has a certain adverse effect on the effect of the added or adhered silicone sheet or gel layer. On the other hand, the method of adding or adhering other materials or coatings cannot be applied to a large area of ​​the long tube Stockings, do not have the function of smoothing the fine lines of the legs

[0026] The present invention also provides a kind of preparation method of above-mentioned nylon 6 filament, specifically comprises the following steps:

[0027] S1. Perform cryogenic treatment on 9.00 to 45.00 parts of polyamide 6 slices. The temperature of the cryogenic treatment is -100°C to -30°C. Then the polyamide 6 slices are crushed and sieved to obtain polyamide 6 powder of 100 mesh to 500 mesh. ; Use liquid nitrogen as the refrigerant to carry out cryogenic treatment on polyamide 6 slices, which can achieve high crushing of polyamide 6 slices in a low temperature environment. The particle size range of polyamide 6 powder from 100 mesh to 500 mesh is convenient for polyamide 6. 6 The powder is fully mixed with nano-sized polytetrafluoroethylene particles, dispersant, and coupling agent;

[0028] S2. Premix 0.50-2.50 parts of polytetrafluoroethylene particles with 0.25-1.25 parts of dispersant to obtain a uniform mixture of polytetrafluoroethylene particles and dispers...

Abstract

The invention relates to the field of chemical fibers, in particular to a chinlon 6 filament and a preparation method thereof. The chinlon 6 filament is prepared from the following raw materials in parts by weight of 0.50-2.50 parts of polytetrafluoroethylene microparticles, 0.25-1.25 parts of dispersing agents, 0.25-1.25 parts of coupling agents and 399.00-495.00 parts of polyamide 6 slices, wherein the polytetrafluoroethylene microparticles are nanoscale polytetrafluoroethylene microparticles, and the coupling agents are silane coupling agents. According to the invention, the polytetrafluoroethylene microparticles are uniformly dispersed on the surface of the polyamide 6 filament provided by the invention, the polyamide 6 filament is woven into silk stockings, and the characteristic of low friction coefficient of a polytetrafluoroethylene material is utilized to reduce the friction between the skin and the stockings, so that the silk stockings have the functions of smoothing fine lines of the legs and preventing aging and dry cracking of the heel, the smoothness of the skin is effectively improved, and the human skin is kept healthy and fine.

Description

technical field [0001] The invention relates to the technical field of chemical fibers, in particular to a nylon 6 filament and a preparation method thereof. Background technique [0002] Nylon 6 fiber, full name polycaprolactam fiber, is mainly used in socks, underwear, sweatshirts, etc. Because nylon 6 filament has high strength, abrasion resistance, and good moisture absorption, it is most suitable for making socks. Stockings woven with nylon 6 filament have good elasticity and high transparency. Stockings woven with nylon 6 elastic silk Flexible and comfortable to wear. At present, in the fierce market competition, the development and production of differentiated and high value-added functional products has become the development direction of the nylon 6 industry, and nylon 6 has been widely used in the high-end hosiery market. [0003] With the improvement of people's living standards, people's requirements for socks are getting higher and higher, and socks with tradi...
