MODIFICATION OF TEXTILE FIBER PROPERTIES BY RADIATION-INDUCED GRAFT POLYMERIZATION

摘要

Investigations of vapor-phase graft polymerization to textile fibers by means of gamma radiation were conducted in the following areas: (1) variables affecting the rate of grafting;(2) modification of fiber properties by grafting;and (3) the kinetics of vapor-phase graft polymerization.nThe effect of the addition of various non-monomeric compounds to the system on the graft polymerization of acrylonitrile, butadiene, vinyl chloride, ethylene, and propylene to various textile fibers was determined. The compounds investigated were water, methanol, ethanol, acetone, ethyl acetate, acetic acid, acetic anhydride, formaldehyde, carbon tetrachloride, and benzene. In general, water, methanol, and acetic acid were the best sensitizers for grafting to cotton, rayon, nylon and wool. The effect of different concentrations of water, methanol, and acetic acid in the vapor-phase on the grafting of acrylonitrile to the various fibers was investigated.
