Abstract

The invention discloses polyaniline-doped bacteriostatic polyester fiber which is prepared from the following raw materials in parts by weight: 120-140 parts of polyethylene glycol terephthalate, 2-3parts of p-toluene sulfonic acid, 0.1-0.2 part of azodicarbonamide, 0.8-1 part of triglycidyl isocyanurate, 1-2 parts of polybenzimidazole, 3-4 parts of calcium propionate, 20-25 parts of fiber cross-linked polyaniline emulsion and 3-4 parts of triethylamine. According to the polyaniline-doped bacteriostatic polyester fiber disclosed by the invention, the added polyaniline can give the fiber unique conductivity, and the polyaniline-doped bacteriostatic polyester fiber is particularly suitable for fabric with a particular purpose, and has excellent comprehensive performance.

Description

technical field [0001] The invention belongs to the field of fibers, and in particular relates to a polyaniline-doped antibacterial polyester fiber and a preparation method thereof. Background technique [0002] Polyester fiber is an important variety of synthetic fibers. It is the trade name of polyester fiber in my country. It uses purified terephthalic acid or dimethyl terephthalate and ethylene glycol as raw materials through esterification or transesterification and polycondensation. The fiber-forming high polymer obtained by reaction - polyethylene terephthalate, the fiber made by spinning and post-processing. Polyester fiber is the simplest one among the three major synthetic fibers, and the price is relatively cheap. In addition, it has the characteristics of strong and durable, good elasticity, not easy to deform, corrosion resistance, insulation, crispness, easy washing and quick drying, etc., so it is loved by people. There are many types of polyester fiber fabri...
