Problems solved by technology
[0005] In the prior art, high polymers or copolymers are used as the matrix, and inorganic antibacterial agents are added or treated with antibacterial agents to obtain antibacterial nylon 6 fibers. Most of the inorganic antibacterial agents use sodium zirconium phosphate silver or copper particles, and the two have long-term contact with the skin. It will have a certain impact on human health after contact, and the antibacterial effect of fiber fabrics will gradually decrease until it disappears after repeated washing. In addition, although these fiber products have antibacterial function, they do not have deodorization function.

[0022] The present invention also provides a preparation method of the above-mentioned antibacterial and deodorant nylon 6 fiber, comprising the following steps:
[0023] Step 1, subjecting 8.40 to 9.07 parts of polyamide 6 slices to cryogenic treatment at a temperature of -100°C to -30°C, and then crushing to obtain polyamide 6 powder of 100 mesh to 500 mesh;
[0024] Step 2, coating the nano-scale antibacterial agent to obtain a nano-scale surface-coated antibacterial agent coated with silicon dioxide or aluminum oxide on the surface;
[0025] Step 3, mixing the polyamide 6 powder obtained in step 1, the nano-scale surface-coated antibacterial agent and the dispersant obtained in step 2 to obtain a composite powder, and the composite powder is granulated to make nylon 6 masterbatch;
[0026] Step 4. Mix the nylon 6 masterbatch obtained in step 3 with the remaining polyamide 6 slices, extrude after melting, enter the spinning assembly, and then wind and form it to obtain nylo...

Abstract
The invention relates to the field of chemical fiber, in particular to antibacterial and deodorant nylon 6 fiber and a preparation method thereof. The antibacterial and deodorant nylon 6 fiber is prepared from the following raw materials in parts by weight: 0.90-1.50 parts of a nanoscale surface-coated antibacterial agent, 0.03-0.10 part of a dispersing agent and 99.07-331.73 parts of a polyamide6 slice, wherein the nanoscale surface-coated antibacterial agent comprises a nanoscale antibacterial agent and a coating film on the surface of the nanoscale antibacterial agent; the weight ratio ofthe coating film to the nanoscale antibacterial agent is 2-5%; the nanoscale antibacterial agent is nanoscale zinc oxide or nanoscale titanium dioxide; the coating film is silicon dioxide or aluminumoxide. In the antibacterial and deodorant nylon 6 fiber provided by the invention, the nanoscale zinc oxide or the nanoscale titanium dioxide is a photocatalyst material, a photocatalytic reaction occurs under ultraviolet irradiation so as to achieve bacteriostatic and deodorant functions, and the bacteriostatic and deodorant functions are high in efficiency and last long.
Description
technical field [0001] The invention relates to the field of chemical fibers, in particular to an antibacterial and deodorizing nylon 6 fiber 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 fiber has high strength, abrasion resistance, and good hygroscopicity, it is most suitable for making socks. The stockings woven with nylon 6 filament have good elasticity and high transparency, and the stockings woven with nylon 6 elastic silk are flexible and comfortable to wear. [0003] With the improvement of people's living standards, people's requirements for clothing or socks are no longer limited to wear resistance, but tend to have clothing or socks with various additional functions such as antibacterial properties, breathability, and deodorization properties. Therefore, it is necessary to be able to modify the fiber. The fiber has the functions...
