Abstract

The invention relates to antistatic polyethylene terephthalate fiber-grade polyester and a preparation method thereof. Aiming at solving the technical problem of overcoming background technological shortcomings, the invention provides antistatic polyester which has permanent antistatic performance and is not influenced by environmental dry humidity, and a preparation method. The antistatic polyethylene terephthalate fiber-grade polyester comprises the following components by mass percent: 0.6-4.0% of barium sulphate, 0.3-2.0% of antimony-doped tin dioxide and 0.2-1.5% of silicon dioxide; and the inherent viscosity is 0.50-0.80dl / g. The preparation method of the invention comprises the following steps: 1) raw material preparation: respectively preparing antistatic serosity, catalyst serosity and monomer mixing serosity; 2) mixing the raw material serosity, pulping, esterifying and polymerizing to obtain the product, or esterifying oligomer on the monomer mixing serosit, adding other serosit to perform prepolycondensation and final polycondensation to obtain the product.

Description

technical field [0001] The invention relates to the technical field of functional fibers, in particular to an antistatic polyethylene terephthalate fiber-grade polyester and a preparation method thereof. Background technique [0002] As the largest variety of chemical fiber, polyester fiber has many excellent properties and is widely used in clothing, decoration and other industrial fields. However, due to the dense crystalline structure, low hygroscopicity and high specific resistance of polyester fiber, it is easy to generate static electricity during production and use, which limits its application range. Endowing polyester fiber with good antistatic properties and improving the wearing comfort and antistatic protection function of polyester fiber fabric clothing is a long-term research topic in the chemical fiber textile industry at home and abroad.
