The preparation method is simple and feasible; and the prepared antistatic agent has a good antistatic effect, good heat resistance and good acid and alkali resistance.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation method of a composite electrostatic agent for fiber fabrics. Background technique [0002] Chemical fibers, especially synthetic fibers, have many excellent characteristics compared with natural fibers, such as they can obtain special performance and aesthetic properties in fiber production and processing, and they are low in price, high in durability, good in strength and toughness, etc. , has been rapidly developed and widely used. Synthetic fibers have many advantages, but there are also many shortcomings that cannot be ignored, such as low hygroscopicity, poor dyeing performance, easy accumulation of charges, static electricity, and poor wearing comfort. There may be more brilliant breakthroughs. [0003] With the rapid and dramatic increase in the output of synthetic fibers, the problem of static electricity in textiles has become increasingly ac...

Problems solved by technology

[0004] Among the currently used antistatic agents, although the cationic antistatic agent has good antistatic effect, its main nitrogen-containing compound is easy to change color in high temperature environment, which affects the dyeing of fibers and fabrics; the antistatic effect of anionic antistatic agent is also low. It is very ideal, but the sulfate ester salt is not stable to oxygen and heat; non-ionic antistatic agent is less toxic than ionic antistatic agent, it is irritating to the skin, and has emulsifying and wetting effects, but its effect on Fiber adsorption is poor and cannot be ionized by itself, so the antistatic effect is poor; organic silicon antistatic agent has outstanding antistatic effect, but it has more residues after thermal decomposition under high temperature and high speed friction, which is easy to form white powder; organic Fluorine-type antistatic agents are rarely used due to their high price; the aqueous solution of polymer-type antistatic agents has a high viscosity, which tends to increase the friction coefficient during high-speed spinning, which is not conducive to preventing the generation of static electricity
