Abstract

The invention relates to a manufacturing method of polyester fiber for industry. The manufacturing method includes following steps: 1), mixing organic calcium carbonate crystal whisker, organic wollastonite nano raphioid fiber, organic barium sulfate nanopowder, theylene glycol, propylene glycol, butylenes glycol, p-hydroxybenzoic acid and sodium germinate to prepare a high-strength high-modulus composite alcohol solution; 2), mixing organic magnesium hydroxide crystal whisker, mica powder, polyethylene glycol, propylene glycol, high-temperature antioxidant 1098, ethylene glycol antimony and protonizing agent phosphoric acid to prepare a high-strength high-modulus composite promoter; 3), subjecting the high-strength high-modulus composite alcohol solution, the high-strength high-modulus composite promoter, purified terephthalic acid and ethylene glycol to co-condensation polymerization to prepare high-strength high-modulus polyester, and spinning to obtain the polyester fiber. By the manufacturing method, flexibility and mobility of molecular chains are improved, and the polyester fiber is endowed with high crystallinity and high processing constancy; the polyester fiber has high strength and modulus, excellent impact resistance and quite good market prospect.

Description

technical field

[0001] The invention relates to a method for manufacturing industrial polyester fibers, belonging to the technical field of textile fiber manufacturing. Background technique

[0002] Polyethylene terephthalate is a polymer compound, which is made by polycondensation of terephthalic acid (PTA) and ethylene glycol (EG), and is abbreviated as PET. Because of its high melting temperature (Tm) and glass transition temperature (Tg), and its excellent comprehensive properties, it is widely used in synthetic fibers, bottle flakes, films and other fields. Due to the steric hindrance effect of the benzene ring of PET resin, the crystallization rate is very slow and the glass transition temperature is high. Especially in the post-processing molding process, the molding cycle is long and the crystallization performance is poor, resulting in a large molding shrinkage rate and poor dimensional stability. It is difficult to endow materials with high-strength and high-modul...
