Abstract

The invention discloses an antistatic agent for a dacron textile as well as a preparation method and an application of the antistatic agent. The preparation method comprises the following steps of: carrying out grafting modification on hyperbranched polyester BoltornH20 by trimethyl oxiranemethaminium chloride and acrylic acid according to the ratio of the amount of substance from 1: 1 to 1: 2; and taking an obtained modified substance to react with acrylamide, dimethyl diallyl ammonium chloride and allyl glycidyl ether to prepare the antistatic agent. According to the antistatic agent of the dacron textile as well as the preparation method and the application of the antistatic agent disclosed by the invention, the process is simpler and a reaction process is convenient to control; the prepared antistatic agent has the stronger cation property and the antistatic function of the dacron textile can be obviously improved; and meanwhile, a lot of reactive functional groups in the antistatic agent can generate cross-linking effect in a finishing and drying process of the dacron textile, the antistatic water-washing resisting performance of the finished textile can be effectively improved, the influences on the hand feel of the textile by the antistatic agent are small.

Description

technical field [0001] The invention relates to an antistatic agent and a synthesis method thereof, in particular to an antistatic agent used for polyester fabrics and a synthesis method thereof. Background technique [0002] Polyester is a widely used synthetic fiber. It has the advantages of durability, good elasticity, not easy to deform, crisp, easy to wash and quick dry, etc., and is very popular among people. However, there are few hydrophilic groups in the polyester fiber structure, poor hygroscopicity, and it is easy to generate static electricity. This leads to polyester fabrics not only absorbing dust in the air during wearing, but also prone to electric shocks. Therefore, during the production process, factories often use antistatic agents to treat polyester fabrics with antistatic treatment, but it is difficult to obtain durable antistatic effects. [0003] Quaternary ammonium salt compounds are widely used as cationic antistatic agents. They not only have good ...
