ACRYLIC FIBER TREATMENT AGENT AND USE THEREOF

摘要

The purpose of the present invention is to provide an acrylic fiber treatment agent which, in the production of carbon fibers, makes it possible to achieve bundling properties of fiber bundles, to prevent fusion between the fibers and to provide stable workability. This acrylic fiber treatment agent contains a compound (A) represented by general formula (1), and a polyether compound (B) having a weight average molecular weight of 8000-25000, wherein the total weight ratio of the compound (A) and the polyether compound (B) is 50-99 wt%. (In expression (1), R1 and R2 are independently a hydrogen atom or an alkyl group. AO is an oxyalkylene group of 2-4 carbon atoms. m and n are each independently a number greater than or equal to 1.)
