Problems solved by technology

Cationic antistatic agents are strongly acidic, although they have good antistatic effects, they are highly corrosive to equipment in the textile processing process, and their use is limited; nonionic antistatic agents are generally polyoxyethylene ether products The mixture of the mixture produces more foam during use, and the raw materials are expensive

Abstract

The invention relates to a method for preparing natural fiber and synthetic fiber antistatic agent. The natural fiber and synthetic fiber antistatic agent is prepared by the following raw materials by the weight percent through reaction: 5-20 of polyoxyethylene fatty alcohol phosphonate, 2-5 of polyoxyethylene fatty alcohol sodium sulfate, 3-10 of coconut acid diethanol amide, 3-6 of trolamine, 0.1-0.3 of EDTA-2Na and the balance of water, wherein the total weight percent of the raw materials is 100 percent. The method for preparing natural fiber and synthetic fiber antistatic agent comprisesthe following process: the polyoxyethylene fatty alcohol phosphonate (7), the polyoxyethylene fatty alcohol sodium sulfate (3), the coconut acid diethanol amide and the EDTA-2Na are added to a reaction bottle prefilled with water; the four raw materials are stirred into the water, heated to 30-100 DEG C and kept at the temperature of 30-100 DEG C for 1-2 hours; the trolamine is dripped to the mixture; and the pH value of the new mixture is adjusted to be 6-7 and stirred to be cooled so that the natural fiber and synthetic fiber antistatic agent is prepared.

Description

(1) Technical field [0001] The invention relates to a preparation method of an antistatic agent for natural fibers and synthetic fibers. It belongs to the technical field of textile auxiliaries. (2) Background technology [0002] During the processing of natural fibers and synthetic fibers, a large amount of static electricity will be generated due to friction and other reasons, which seriously affects production efficiency and product quality. Therefore, in the process of processing, various antistatic agents are mostly used to eliminate the static electricity generated in the process of processing, so as to improve production efficiency and product quality. There are two main types of antistatic agents currently in use: cationic antistatic agents and nonionic antistatic agents. Cationic antistatic agents are strongly acidic, although they have good antistatic effects, they are highly corrosive to equipment in the textile processing process, and their use is limited; noni...
