Abstract

The invention discloses a mildew-proof polyester high-strength yarn preparation method which particularly includes the steps: S1 synthesizing dipentene-4-dimethyl succinate; S2 synthesizing isopentenol formic ether; S3 synthesizing a bisabolol derivative by the dipentene-4-dimethyl succinate and the isopentenol formic ether; S4 synthesizing mildew-proof polyester: performing esterification polycondensation on the bisabolol derivative and terephthalyl alcohol to obtain mildew-proof polyester; S5 preparing mildew-proof polyester high-strength yarns: adding the mildew-proof polyester, dispersingagents, defoaming agents and softening agents into a screw extruder for melting extrusion, performing melt filtration, liquid-phase viscosity increasing and spinneret hole extrusion to form trickles,and performing cross air blast cooling, sliver oiling and winding to form the mildew-proof polyester high-strength yarns. The method is scientific, reasonable, good in air permeability, moisturizing properties and skin touch sense and soft in hand feeling, a prepared mildew-proof polyester fabric is excellent in mildew-proof antibacterial effect, and wearing comfort is improved.

Description

technical field [0001] The invention belongs to the technical field of fabrics, and in particular relates to a method for preparing mildew-proof polyester high-strength yarn. 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. Textiles are prone to embrittlement and even aging after mildew. With the development of social economy and the im...
