Document Type and Number:
Japanese Patent JPS5719229
Kind Code:
B2
Abstract:
A method for manufacturing heat-resistant polyvinyl chloride fiber is given without injuring the flame-retardance of the polyvinyl chloride fiber, by grafting acrylic acid or calcium acrylate onto polyvinyl chloride by a radiation chemical process. The polyvinyl chloride fiber is irradiated either in contact with a mixture of water, ethylene dichloride and acrylic or in contact with a mixture of methanol, water, ethylene dichloride and calcium acrylate. In the case of the grafting of acrylic acid the graft fiber is subjected to a heat treatment or grafted polyacrylic acid is converted to a divalent metal salt.
