Description
Technical Field
The invention relates to the technical field of chemical fiber fabrics, in particular to an antibacterial thermal chemical fiber fabric and a preparation method thereof.
Background
Fabric is the material used to make clothing. As one of the three elements of the garment, the fabric not only can explain the style and the characteristics of the garment, but also directly controls the expression effects of the color and the shape of the garment. The functional fabric refers to a fabric with certain special performance and purposes, such as water resistance, wind resistance, air permeability, moisture permeability, heat preservation, oil resistance, easy decontamination, bacteria resistance, deodorization, ultraviolet resistance, static resistance, radiation resistance, flame resistance, high temperature resistance, acid and alkali resistance and the like. The functional fabric in the market is mainly made of garment fabric and is mainly used for outdoor sportswear and high-grade casual clothes.
The fiber is made of natural or artificial high molecular substance. Common textiles, such as viscose, polyester card, nylon silk stockings, acrylic wool, and polypropylene carpets, are made of chemical fibers. According to different sources of raw materials, chemical fibers can be divided into: firstly, the artificial fiber takes natural high molecular substances (such as cellulose and the like) as raw materials and comprises viscose fiber and the like; secondly, synthetic fiber is made of synthetic polymer, such as terylene; and the inorganic fiber is prepared from inorganic matters and glass fiber.
However, the chemical fiber fabrics used at present have the following problems:
1. the antibacterial performance is poor;
2. the heat retention property is poor;
3. the chemical fiber fabric modified by adding the filler has poor comprehensive properties such as elasticity, mechanical strength and the like.
Disclosure of Invention
Based on the situation, the invention aims to provide the antibacterial thermal-insulation chemical fiber fabric and the preparation method thereof, and the problems can be effectively solved.
In order to solve the technical problems, the technical scheme provided by the invention is as follows:
an antibacterial warm-keeping chemical fiber fabric is prepared by knitting or weaving antibacterial warm-keeping composite fibers;
the antibacterial warm-keeping composite fiber is prepared from the following raw materials in parts by weight:

Preferably, the degree of substitution of the chitosan quaternary ammonium salt is 87-89%, and the molecular weight is (8.7-9.1) × 104u。
The diameter of the calcium silicate nanometer micro-sheet is 0.8-1.2 mu m, the thickness of the calcium silicate nanometer micro-sheet is 90-105 nm, and the heat insulation performance of the antibacterial warm-keeping chemical fiber fabric can be further improved, and the heat insulation performance is improved.
More preferably, the diameter of the calcium silicate nanometer microchip is 0.8-1.2 μm, and the thickness is 90-105 nm.
Preferably, the calcium silicate nanometer microchip has a micropore structure, and the pore diameter of 90% of pores is 20-60 nm.
Preferably, the processing aid is a mixture of stearic acid and epoxidized octyl soyate.
Preferably, the mass ratio of stearic acid to octyl epoxy soybean oleate in the mixture of stearic acid and octyl epoxy soybean oleate is 1: (1.3-1.4).
The invention also provides a preparation method of the antibacterial thermal-insulation chemical fiber fabric, which comprises the following steps:
A. weighing ethylene glycol terephthalate, polyacrylonitrile, a polyurethane elastomer, silver sulfadiazine, chitosan quaternary ammonium salt, calcium silicate nano micro-sheets, silicon dioxide aerogel and a processing aid according to the weight parts, respectively drying the ethylene glycol terephthalate, the polyacrylonitrile and the polyurethane elastomer, and then uniformly mixing the raw materials for later use;
B. feeding the mixed raw materials into a double-screw extruder to be melted into a composite melt;
C. sending the composite melt into a spinning machine, spraying the composite melt from a spinneret plate to form a strand, and then performing air blowing cooling, oiling, stretching and winding to obtain the antibacterial warm-keeping composite fiber;
