[0002] Polyester fiber is an important textile raw material with many excellent properties. It is widely used in clothing, decoration and other industrial fields. However, polyester fiber is prone to static electricity due to friction during use. This static electricity is harmful to human health and the manufacture of chemical fiber products. , use will bring certain negative effects
[0003] At present, most of the common antistatic polyester fibers are obtained by adding cationic antistatic agents to the raw materials and then spinning. The antistatic agent will be reduced due to being dissolved in water, resulting in a decrease in the antistatic ability of the antistatic polyester fiber, which in turn makes the antistatic effect of the antistatic polyester fiber last for a short time

Abstract

The invention relates to the field of high polymer materials, in particular to a super-elastic antistatic wool top fiber and a production process thereof.The super-elastic antistatic wool top fiber is prepared from, by weight, 60-70 parts of PET polyester, 8-16 parts of modified kaolin, 2-6 parts of a dispersing agent and 6-12 parts of a cationic antistatic agent, and the modified kaolin is prepared through the following method that a silane coupling agent is added into water to be dissolved; and soaking the calcined kaolin in a silane coupling agent aqueous solution, drying, grinding, filtering, and drying to obtain the modified kaolin. The antistatic polyester fiber has the effect of prolonging the lasting time of the antistatic effect of the polyester fiber.

Description

technical field [0001] The present application relates to the field of polymer materials, and more particularly, to a superelastic antistatic top fiber and a production process thereof. Background technique [0002] Polyester fiber is an important textile raw material with many excellent properties and is widely used in clothing, decoration and other industrial fields. However, polyester fiber is prone to generate static electricity due to friction during use. This static electricity is harmful to human health and the manufacture of chemical fiber products. , use will bring certain negative effects. [0003] At present, most common antistatic polyester fibers are obtained by adding a cationic antistatic agent to the raw material and then spinning. However, since the cationic antistatic agent is easily soluble in water, after the antistatic polyester fiber encounters water, the cationic The antistatic agent will be reduced by dissolving in water, resulting in a decrease in t...
