Title:
PRODUCTION OF FIBER COMPOSED OF FLUOROCARBON POLYMER
Document Type and Number:
Japanese Patent JPS6461507
Kind Code:
A
Abstract:
PURPOSE: To obtain the titled fiber having high strength to enable weaving or knitting as it is and useful for the adsorption and recovery of heavy metals, adsorption of surfactants, adsorption of proteins, recovery of acids and refining of water, by drawing a fiber having -SO3X, etc., on side chain at a specific temperature.
CONSTITUTION: The objective fiber composed of a fluorocarbon polymer (preferably a perfluorocarbon polymer) having a breaking strength of at least 1.0g/ denier is produced by drawing a fiber having -SO3X (X is H, NH4, alkali metal or alkaline-earth metal) and/or -CO2X groups on side chain at a temperature above 100°C and below the decomposition temperature of the side chain.
