Description

DETAILED DESCRIPTION OF THE INVENTION The present invention prevents static electricity from being generated and accumulated in the threads due to contact between the fiber threads and materials such as guides, rollers, and heaters during the manufacturing and processing processes of synthetic fibers. The present invention relates to a novel oil for textile treatment that is suitable for effectively preventing and reducing various problems caused by the generation and accumulation of static electricity.

In general, thermoplastic synthetic fibers such as polyester, nylon, and polypropylene are usually obtained by melt spinning, applying a fiber treatment oil to undrawn yarns, then drawing them 4 to 5 times, and heat setting them to fix their properties. Ru.

These drawn yarns are further subjected to bulk processing, twisting, warping, knitting,
Textile products are made through high-level processing processes such as weaving, but these manufacturing and processing processes are often industrially processed at fairly high speeds, and due to these high-speed manufacturing and processing processes, various types of static electricity are generated. Obstacles such as thread fluff, walnuts, roller wrapping, etc. are becoming increasingly serious problems.

In order to reduce such troubles and make manufacturing and processing more efficient, we need a fiber processing oil that can minimize the static electricity generated on the threads due to friction and impart a high level of smoothness to the threads. is required.

Various ionic surfactants have been proposed as antistatic agents for use in textile treatment oils.
It has been pointed out that when the process speeds up, especially under severe conditions such as high temperature, high tension, and high speed, the performance that satisfies the various required characteristics as described below is not yet achieved.

That is, under conditions where manufacturing and processing speeds are increased, (1) heat resistance decreases, (2) scum accumulates on guide rollers, etc., (3) metal wear resistance decreases, and (4) friction coefficient decreases. Problems such as increase in static electricity are likely to occur, and the causes include performance impairment due to antistatic agents added to textile processing oils, inappropriate selection of antistatic agents, and excessive addition of antistatic agents. .

In view of the above-mentioned circumstances, the present inventors have developed an oil agent for textile treatment that has good anti-static properties and does not cause the various problems described above, with the addition amount sufficient to exhibit anti-static properties. As a result of repeated research, we have found that alkali metal or alkaline earth metal salts of sulfonate compounds having free carboxyl groups, as described below, and/or citrus salts in which the free carboxyl groups of the sulfonate compounds are neutralized with amine compounds are excellent. By using a synthetic fiber treatment oil that exhibits antistatic properties and contains one or more selected from these sulfonate compounds together with a smoothing agent such as mineral oil, aliphatic ester, or polyoxyalkylene glycol derivative. The present invention was achieved by confirming that the other accompanying drawbacks as described above can be alleviated.
