Abstract

The ivention provided a fiber sizing agent highly stable in its emulsion form and excellent in uniform pickup tendency on a filament undergoing high-speed sizing operation. The fiber sizing agent comprises (A) a base oil, (B) a polyhydric alcohol fatty acid ester alkylene oxide adduct and (C) a monohydric alcohol alkylene oxide adduct, wherein the component C essentially includes a compound(c1) of the general formula(1):R-O-(PO)m-(EO)nH(wherein, R is a 4-15C alkyl; PO is an oxypropylene group; EO is an oxyethylene group; m is an integer of 10-40; and n is an integer of 5-15).

Description

technical field [0001] The present invention relates to a fiber treatment agent for synthetic fibers. More specifically, it relates to a fiber treatment agent used in the spinning process of synthetic fibers. Background technique [0002] In the spinning manufacturing process, in order to smoothly spin and draw the fibers, a fiber treatment agent is used that uniformly adheres to the fibers and imparts lubricity, bundling properties, antistatic properties, and the like. In recent years, with the increase in speed of the processing process, the amount of fiber treatment agent attached to the fiber in the spinning process tends to be uneven, and a slight unevenness in the amount of adhesion will cause problems such as broken filaments, burrs, and uneven dyeing. . In order to solve this problem, it is known that a method of imparting uniform adhesion to fibers can be employed by blending polyoxyethylene octyl ether in a fiber treatment agent (Japanese Patent Publication No. 0...
