DESCRIPTION:

BRIEF SUMMARY
FIELD OF THE ART

This invention relates to a novel oiling agent for treating synthetic fibers which is suitable for effectively preventing generation and accumulation of static electricity in filaments, caused by contact of materials of guides, rolls, heaters, etc. with fiber filaments in the production step and the processing step of synthetic fibers, to thereby diminish various obstacles due to such generation and accumulation of static electricity.


ART OF THE BACKGROUND

Generally, in the case of thermoplastic synthetic fibers such as polyester, nylon, polypropylene, etc., an oiling agent for treating fibers is attached to unstretched filaments, followed by stretching to 4 to 5 times the original length and heat-set for fixing the properties. The resulting stretched filaments are further passed through advanced processing steps such as bulky processing, twisting, warping, knitting, weaving, etc. to give fiber products, and in such production step and processing step, filaments are industrially very often treated at considerably high speed and temperature; thus, various obstacles due to static electricity generated by such speed-up of production and processing, such as filament splitting, jumping-out from filament path, filament swing on heater, twining round roller, etc. have become a more and more serious problem. In order to diminish such obstacles and thereby carry out the production and processing with good efficiency, an oiling agent for treating fibers has been required which reduces static electricity generated on filaments due to friction as much as possible, further imparts a large extent of lubricating property onto filaments and does not contaminate heater so much.
As antistatic agents used for fiber-treating oiling agents, various kinds of ionic surfactants have so far been proposed, but it is pointed out that for the speed-up of the steps, and particularly under severe conditions of high temperature, high tension, high speed, etc., they have not been yet provided with fully satisfactory performances for various required characteristics as mentioned below.
Namely, under conditions of speed-up and higher temperature of the production and processing, such problems as (1) increase in frictional static build-up voltage, (2) deposition of tar onto heater and (3) increase in frictional coefficient are liable to be raised, and this results from inhibition of performances due to antistatic agent added to the fiber-treating oiling agent, inadequate choice of antistatic agent, its excess amount added, etc.


DISCLOSURE OF THE INVENTION

In view of the above-mentioned status, the present inventors have made studies on a fiber-treating oiling agent having a superior antistatic property, which is added in an amount in which the antistatic property is fully exhibited, and does not raise the above-mentioned various problems, and as a result, have confirmed that a fluoric ionic surfactant having a specific structure as described later exhibits a superior antistatic property, and when an oiling agent for treating synthetic fibers containing one kind or two kinds or more of the fluoric ionic surfactant and a lubricating agent such as a poly(oxyethylene-oxypropylene) ether derivative is used, it is possible to diminish the above-mentioned problems; thus have attained the present invention.
An object of the present invention is to provide a fiber-treating oiling agent which effectively inhibits static electricity generated when filaments cause friction against guides, rollers, heaters, etc. in the production and processing of synthetic fibers, and yet does not cause various obstacles brought by antistatic agents contained in the treating oiling agent.
Another object of the present invention is to provide a fiber-treating oiling agent which effectively inhibits generation of antistatic electricity in an extremely small amount of antistatic agents added.
The present invention is directed to an oiling agent for treating synthetic fibers which comprises
(I) 0.05 to 5% by weight of a fluorine-containing ionic sur
