Problems solved by technology

[0003] At present, the wig fibers in the market have disadvantages such as poor wear resistance, limited mechanical strength and flexibility, narrow processing range, and complicated processing technology during production and use.
And in the process of wearing and using the wig, due to direct or indirect contact with the human body and the secretion of sweat, rain, etc. are easy to breed bacteria, so the wig needs to have a certain antibacterial effect, but so far the research and production in this area are relatively scarce

Embodiment 1

[0026] Modified nylon 66 is prepared according to the following steps:

[0027] Hexamethylenediamine and adipic acid with a weight ratio of 48% were respectively added to the polymerization reactor, and a nitrogen-containing phosphorus flame retardant with a weight ratio of 4% was weighed and added to the reactor. The reaction system is heated at 220-230° C. and 1.25-1.35 MPa for 2.5-3 hours. Then slowly increase the temperature to 260°C within 2 hours, maintain the system at 260°C and continuously exhaust and reduce the pressure, reduce the system to 2.4kPa at a uniform speed within 6 hours, keep the system at 260°C and 2.4kPa for 2 hours, then Cool in a cold water tank and pelletize to obtain modified nylon 66 masterbatch with a viscosity of 3.2-3.3.

[0028] The nitrogen-containing phosphorus flame retardant is: one or more of melamine cyanurate, melamine phosphate, melamine pyrophosphate or melamine polyphosphate.

Embodiment 2

[0030] A flame-retardant antibacterial nylon wig fiber, comprising the following steps:

[0031] (1) Percentage by weight: 85% of raw material modified nylon 66, 5% of flame retardant, 2% of synergistic flame retardant, 5% of antibacterial agent, 1% of dyeing agent, 1% of auxiliary additive, and 1% of dispersant ;

[0032] The modified nylon 66 is prepared from Example 1; the flame retardant is brominated epoxy resin; the synergistic flame retardant is antimony trioxide and silicon stannate, with a weight ratio of 1:2; The antibacterial agent is a quaternary ammonium salt antibacterial agent, chitosan and nano-silver antibacterial agent, and the weight ratio is 6:9:1; the additive is nano-calcium carbonate and silicon dioxide, and the mass ratio is 1:1; the dispersant Be the dispersed wax of molecular weight 200; Described dyeing agent is brown masterbatch;

[0033] (2) Dehumidify and dry the raw material at 95°C; the total time for dehumidifying and drying is 10 hours, and ...

Embodiment 3

[0040] A flame-retardant antibacterial nylon wig fiber, comprising the following steps:

[0041](1) Percentage by weight: 85% of raw material modified nylon 66, 5% of flame retardant, 2% of synergistic flame retardant, 5% of antibacterial agent, 1% of dyeing agent, 1% of auxiliary additive, and 1% of dispersant ;

[0042] The modified nylon 66 is prepared from Example 1; the flame retardant is brominated polystyrene; the synergistic flame retardant is antimony trioxide and silicon stannate, with a weight ratio of 1:2; Described antibacterial agent is quaternary ammonium salt antibacterial agent, chitosan and nano-silver antibacterial agent, weight ratio 6:9:1; Described additive is talcum powder; Described dispersant is the dispersing wax of molecular weight 200; Described dyeing agent It is brown masterbatch;

[0043] The remaining steps are the same as steps (2) to (8) in Example 2 to obtain antibacterial and flame-retardant nylon wig fibers.

Description

technical field [0001] The invention relates to the technical field of artificial wigs, in particular to a flame-retardant and antibacterial nylon wig fiber and a preparation method thereof. Background technique [0002] In modern life, wigs have not only become a necessity for people to pursue fashion and beauty, but also provide a good solution for people with hair problems. The raw materials of wigs generally come from natural wigs and artificial artificial wig fibers. Due to the rapid increase in the demand for hair products at home and abroad, and the strengthening of environmental protection awareness in various countries around the world, the processing technology of natural human hair has caused serious pollution to the environment and water sources. Artificial imitation human hair fiber as a human hair substitute is the ultimate trend of hair product raw materials. [0003] At present, the wig fibers circulating in the market have disadvantages such as poor wear re...
