Problems solved by technology

[0004] However, due to the tight arrangement of the internal molecules of polyester and the lack of a hydrophilic structure between the molecules, the moisture regain is very small and the hygroscopicity is poor.
Under the condition of a relative humidity of 95%, its highest moisture absorption rate is 0.7%. Due to its poor hygroscopicity and poor resistance, polyester fabrics have poor air permeability, poor dyeability, and poor pilling resistance.

Abstract

The invention belongs to the field of clothes textiles, and particularly relates to a moisture-absorbing anti-static and anti-bacterial polyester fiber, a moisture-absorbing anti-static and anti-bacterial fabric and preparation and application. A preparation method of the moisture-absorbing anti-static and anti-bacterial polyester fiber comprises the following steps of mixing and spinning polyethylene terephthalate, polyvinyl alcohol, nanosilver and polyethylene glycol, so as to obtain mixed fiber; respectively treating the mixed fiber by a lipase water solution and a quaternary ammonium salt chitosan / glyoxal solution, and washing by water; stretching the mixed fiber after water washing, coiling, and thermally shaping, so as to obtain the moisture-absorbing anti-static and anti-bacterial polyester fiber. The moisture-absorbing anti-static and anti-bacterial fabric comprises the moisture-absorbing anti-static and anti-bacterial polyester fiber. The prepared moisture-absorbing anti-static and anti-bacterial polyester fiber has the advantages that the defects of poor moisture absorbing property, low moisture regain rate, easiness in electrostatic charge forming and the like in the unmodified polyester fiber are overcome; the water absorbing property, moisture absorbing property, anti-static property and antibacterial property are good.

Description

technical field [0001] The invention belongs to the field of clothing textiles, and in particular relates to a hygroscopic antistatic antibacterial polyester fiber, a hygroscopic antistatic antibacterial fabric and their preparation and application. Background technique [0002] Polyester is an important variety of synthetic fibers and is the trade name of polyester fibers in my country. Polyester is a fiber-forming polymer made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reactions— - Polyethylene terephthalate (PET), fibers made by spinning and post-processing. In 1941, British Whenfield and Dikson synthesized polyethylene terephthalate for the first time using terephthalic acid and ethylene glycol as raw materials and made it into fibers. Polyester was industrialized in the UK in 1946, and began to be produced on a large scale worldwide in 1953. In 1971, ...
