Abstract

The invention relates to a multifunctional polyester stable fiber manufacturing method with functions of flame retardance, anti-static electricity and ageing resistance. The method includes: subjecting magnesium hydroxide whiskers, zinc oxide, conductive mica powder and the like with the flame retardant and antistatic functions to grinding reaction with glycol, p-hydroxybenzoic acid and the like to obtain multifunctional flame-retardant and antistatic alcohol; mixing anti-aging material of triazine-5 light stabilizer, high-temperature oxidation inhibitor and UV(ultraviolet)-327 ultraviolet light absorber with the glycol, sodium alginate and the like to obtain composite antiager after grinding reaction; subjecting certain proportion of purified terephthalic acid with the glycol and the multifunctional flame-retardant and antistatic alcohol to mixing and multiple copolycondensation, and continuously adding the composite antiager in the late esterification reaction to obtain the reactive-type multifunctional polyester with flame-retardant, antistatic and antiaging functions. The multifunctional polyester is melt and spun into multifunctional polyester stable fiber.

Description

technical field [0001] The invention relates to a method for producing multifunctional polyester staple fibers, which comprises the steps of taking flame-retardant, antistatic and antiaging modifiers into copolymerization reaction to produce multifunctional polyester, and melt spinning to produce multifunctional polyester staple fibers , belongs to the technical field of chemical fiber manufacturing. Background technique [0002] Polyester Polyethylene terephthalate (PET). Polyethylene terephthalate (PET) is produced by polycondensation of terephthalic acid (PTA) and ethylene glycol (EG). It is a crystalline saturated polyester, a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. PET has excellent physical and mechanical properties in a wide temperature range. The glass transition temperature of polyester is 69°C, the softening range is 230-240°C, and the melting point is 255-260°C. It has good fiber-forming properties, mechanical pro...
