Abstract

The invention discloses a preparation method of breathable and bacteriostatic fabric. The preparation method comprises the following specific steps: S1, synthesizing methyl bipentene-4-succinate; S2,synthesizing isopentenol formate; S3, synthesizing a bisabolol derivative from the methyl bipentene-4-succinate and the isopentenol formate; S4, adding terephthalic acid, the bisabolol derivative, ethylene glycol and a catalyst aluminum acetate into a stainless steel reaction kettle, and performing esterification polycondensation to obtain an oligomer; S5, after the esterification prepolymerization in the step S4, continuing performing polycondensation to obtain modified polyester; S6, adding the modified polyester, a dispersing agent, a defoaming agent and a softening agent into a screw extruder, performing melt extrusion, then performing melt filtration, performing liquid phase thickening, performing spinneret orifice extrusion to form a fine flow, performing side blowing cooling, performing strand oiling, performing winding mouling to obtain polyester high-strength yarns, dyeing and finishing, and spinning to obtain the breathable and bacteriostatic fabric. The preparation method isscientific and reasonable; the prepared breathable and bacteriostatic fabric has good breathability and bacteriostasis.

Description

technical field [0001] The invention belongs to the technical field of fabrics, and in particular relates to a preparation method of breathable antibacterial fabrics. Background technique [0002] Textiles can absorb various nutrients in the air. Under suitable temperature and humidity conditions, microorganisms residing on textiles can reproduce and spread in large numbers, decompose and produce secretions, bring ammonia and other odorous substances, or form bacteria on fabrics. The mildew of textiles is very serious. Most of the bacteria will secrete various pigments, which will contaminate the textiles with red, blue, purple and black stains, seriously affecting the finishing effect and the quality of finished products. Harmful microorganisms can multiply rapidly under suitable environmental conditions and spread diseases, affecting people's health. With the development of social economy and the improvement of living standards, new market demands are generated. Consumers...
