Abstract

The invention discloses a moisture-absorbing and breathable chemical fiber fabric and a preparation method thereof. The moisture-absorbing and breathable chemical fiber fabric is prepared from moisture-absorbing and breathable composite fibers through a knitting or weaving process; the moisture-absorbing and breathable composite fibers are prepared from the following raw materials in parts by weight of 65 to 75 parts of ethylene glycol terephthalate, 20 to 27 parts of bamboo pulp viscose, 8 to 11 parts of a polyurethane elastomer, 4 to 5 parts of a sodium acrylate-N,N'-dihydroxyethyl acrylamide copolymer, 2.5 to 3.5 parts of polyethylene glycol, 2 to 2.6 parts of carboxymethyl cellulose, 5 to 7 parts of a filler, 3 to 4 parts of an antioxidant and 3 to 4 parts of a heat stabilizer. The moisture-absorbing and breathable chemical fiber fabric is large in moisture absorption constant, high in moisture absorption speed, high in water absorption rate, large in moisture absorption capacity and good in comprehensive moisture absorption performance; the air permeability is high, and the air permeability is good; the tensile strength is high and the mechanical property is good; and various performance indexes are excellent, and the comprehensive use performance is good.

Description

technical field [0001] The invention relates to the technical field of chemical fiber fabrics, in particular to a moisture-absorbing and breathable chemical fiber fabric and a preparation method thereof. Background technique [0002] Fabric is the material used to make clothing. As one of the three elements of clothing, fabrics can not only interpret the style and characteristics of clothing, but also directly affect the color and shape of clothing. Among them, functional fabrics refer to fabrics with certain special properties and uses, such as waterproof, windproof, breathable, moisture-permeable, warm, oil-proof, easy to decontaminate, anti-bacterial and deodorizing, anti-ultraviolet, anti-static, anti-radiation, Anti-flame retardant, high temperature resistance, acid and alkali resistance and other functions. The functional fabrics on the market are mainly clothing fabrics, which are mostly used in outdoor sportswear and high-end casual wear. Among the new functional ...
