Treating agent for fiber

TLDR: In this paper, the subject treating agent is applied to the fiber in processes ranging from a fiber-producing process to a finishing process, preventing the breakage of the fiber caused by the friction between the fiber and various guides in a high speed spinning process, drawing process, etc., and contriving the improvement of the operability of the processes by containing a phosphorodithioate metal salt.

Abstract: PURPOSE: To provide the subject treating agent applied to the fiber in processes ranging from a fiber-producing process to a finishing process, preventing the breakage of the fiber caused by the friction between the fiber and various guides in a high speed spinning process, drawing process, etc., and contriving the improvement of the operability of the processes by containing a phosphorodithioate metal salt. CONSTITUTION: A fiber-treating agent contains a phosphorodithioate of the formula (R and R 1 are alkyl or aryl; A is 2-4C alkyl; X is mono-tetravalent metal element; (p) and (q) are 0 or an integer of ≥1; (n) is 1-4), and if necessary, at least one of a known leveling agent, a surfactant, a destaticiing agent, etc. The treating agent is emulsified and subsequently supplied to a fiber such as natural fiber or synthetic fiber with a roller in a process between the preparation process of the fiber and the finishing process thereof, thereby reducing a high load friction between the fiber and the metal, a friction between the fiber and various guides in a high speed spinning or drawing process, a friction between the fiber and a palcon ring in a high speed fine spinning process and a friction between the fibers of a tire cord and a hot roller in a high contact pressure state, and preventing the breakage of the fiber and the lowering of the operability of the processes.
