Abstract

The invention discloses a long-effective bacteriostatic polyamide fiber composite material and a preparation method thereof. The long-effective bacteriostatic polyamide fiber composite material comprises the following components in parts by weight: 40-60 parts of a polyamide fiber, 2-6 parts of potassium sorbate, 2-6 parts of benzoic acid, 1-10 parts of hydroxyethyl dodecyl alcohol, 1-4 parts of pentaerythritol, 3-11 parts of chitosan, 1-3 parts of thymol crystals, 1-3 parts of lauryl sodium sulfate, 1-5 parts of polyethylene wax, 3-10 parts of titanium dioxide, 3-8 parts of stearate, 2-8 parts of dibutyltin dilaurate and 1-3 parts of a fire retardant. The bacteriostatic effect of the composite material is obvious; the antibacterial activity on escherichia coli and staphylococcus aureus can reach over 95%; the bacteriostatic time is long; the antibacterial activity is not weakened by further treatment on the composite material; and the validity of bacteriostasis can reach over a year.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a long-acting antibacterial polyamide fiber composite material and a preparation method thereof. Background technique [0002] Polyamide fiber has a series of excellent properties such as good elasticity, good wear resistance, high strength, high surface gloss, alkali resistance and reduction resistance, so it is widely used in the three major fields of clothing, industrial use and decorative carpets , especially in the field of decorative carpet silk has great potential. my country's polyamide fiber product specifications are complete, and products in the three major fields of clothing silk, industrial silk and decorative carpets can be produced. However, the industrial structure is unreasonable, especially the output of differential polyamide fibers is low and there are few varieties. At present, only special-shaped fibers, composite superfine fiber...
