Abstract

The invention relates to a processing method of antistatic bright polyester fiber. The processing method is characterized by comprising the following specific steps: (1) the surface treatment is performed for nanometer zinc oxide; (2) a carboxylic acid terminated CBT initial polymer is generated; (3) the in-situ polymerization is performed for improved PBT; (4) an antistatic polyester slice is prepared; and (5) the antistatic fiber is prepared; the melt spinning is performed for the antistatic polyester slice, wherein a spinneret plate is an abnormal spinneret plate; and the obtained antistatic polyester slice is bright polyester polyester fiber. The antistatic PET fiber is prepared through the chemical bond combining effect of the nanometer zinc oxide; as the nanometer zinc oxide has good shielding effect, the antistatic performance of the nanometer zinc oxide is efficient and long-lasting; and the nanometer zinc oxide has the advantages of good heat resistance, stable performance, low cost, simple process and easy promotion.

Description

【Technical field】 [0001] The invention relates to the technical field of textile production, in particular to a processing method of an antistatic bright polyester fiber. 【Background technique】 [0002] Chinese patent application number 201110385560.X relates to an antistatic polyester, which is composed of terephthalic acid, ethylene glycol, aliphatic diols with side chains and less than 6 carbon atoms, polyethylene glycol and sulfonic acid It is formed by copolymerization of acid salt antistatic agent. The aliphatic diol with side chain and less than 6 carbon atoms is 2-methyl-1,3-propanediol, and the content of this structural unit accounts for 1% of the antistatic polyester. 1~15mol% of the total amount of diol components; antistatic polyester not only has excellent antistatic performance, but also has excellent antistatic durability, and can still maintain excellent antistatic properties after being processed into fiber fabrics after dyeing and other post-processing tre...
