Title:

MANUFACTURE OF FLAMEPROOFING ACRYLONITRILE FIBER

Document Type and Number:

Japanese Patent JPS59173313

Kind Code:

A

Abstract:

PURPOSE: To manufacuture a flameproofing fiber having high tensile strength and elongation and excellent applicability to flameproof clothes, etc., by carrying out the flameproofing treatment and the shrinkage treatment of an acrylonitrile fiber under specific condition.

CONSTITUTION: An acrylonitrile fiber is subjected to (1) the flameproofing treatment in an oxidizing atmosphere, e.g. in air, O2, HCl, etc. at 200W400°C to an equilibrium water-content of 6.5W15%, and then (2) the shrinkage treatment in steam or hot water at ≤150°C preferably for 1minW2hr to effect shrinkage of 0.5W20%.
