Wet spinning methods and dry spinning methods are known as the above-mentioned "method using a solvent", and melt spinning methods are known as the above-mentioned "method using no solvent".

[0003] A salt-like resin has a high melt viscosity and an extremely low spinnability, so a salt-like resin is melt-spun to obtain a certain quality of vinyl chloride fiber. There was a problem that it was difficult to do. The salt-and-boil type resin is desalted into the salt-and-vinyl polymer that constitutes a salt-type resin when exposed to high temperature environments and exposed to sunlight and ultraviolet light. As a hydrogen peroxide reaction occurs, chloride-based fibers composed of chloride-based resins are 1) poor in initial colorability, and 2) easily become strong yellowish fibers. 3) There was a problem that the product value might be reduced.

A mixture of (a) 35 parts by weight of (a) ethylene-butyl acetate based resin, (b) 0.2 to 5.0 parts by weight of a heat stabilizer, and (c) 0.2 to 5.0 parts by weight of a lubricant per 100 parts by weight of the mixture. In addition, a chloride-based boule-based fiber has been proposed which also has the strength of a salt-like bole-based resin composition (see Patent Document 1). ₀ And, in Patent Document 1, tin is used as the heat stabilizer (b). System heat stabilizer, Ca-Zn system heat stabilizer, hydrotalcite-based heat stabilizer, and zeolitic system heat stabilizer at least one selected from the group consisting of The use of seeds is disclosed.
