Problems solved by technology

Cationic antistatic agents are generally used most frequently with quaternary ammonium salts. In addition to good antistatic effects, this type of surfactant also has a certain washability. Generally, it can be washed for 5 to 10 times, but the treated fibers or fabrics The hand feel is not very good, and its adhesion to the surface of the equipment is relatively large, which affects continuous production

Abstract

The invention relates to a durable cationic antistatic agent for polyester fabrics and a preparation method thereof. The durable cationic antistatic agent comprises the following raw materials in parts by weight: 70-100 parts of polyethylene glycol, 13-16 parts of ethylene glycol, 17-20 parts of dimethyl terephthalate, 16-90 parts of polyamide, 12-24 parts of 1-bromo-alkyl, 0.6-1 part of metal acetate and 24-40 parts of isopropyl alcohol. The cationic antistatic agent can be used for modifying polyester, and the modified polyester is good in fluffy and soft feelings, antistatic property, smooth hydrophilicity and the like. The cationic antistatic agent is good in wash resistance and can be washed by water for at least 30 times. Moreover, the preparation method of the cationic antistatic agent is simple and practicable and can be applied to continuous production.

Description

technical field [0001] The invention relates to a durable cationic antistatic agent for polyester fabric and a preparation method thereof. Background technique [0002] Polyester fiber fabric has become one of the most popular products due to its high strength, wrinkle resistance, wear resistance, stable size, easy washing and quick drying, and no ironing. It is widely used in clothing, decoration and industrial textiles. However, polyester is a hydrophobic fiber, lacks hygroscopic groups, and is a poor conductor; its moisture absorption rate is low; therefore, it is easy to generate static electricity when it rubs against other objects, if these static charges cannot be quickly dissipated through various channels, it will Gradually accumulate and increase on materials and processing machinery, causing various obstacles and hazards. [0003] Among the traditional antistatic agents, cationic antistatic agents are the most widely used, have strong adsorption force to fibers, ...
