Abstract

The invention relates to a process for imparting permanent antistatic properties to filaments, fibers and sheets of homo- and copolymers of acrylonitrile by incorporation of alkylolamine salts of branched alkylbenzenesulfonic acids, the alkylol radical(s) having from 2 to 4 and the alkyl radical from 9 to 20 carbon atoms, and the filaments, fibers and sheets manufactured according to this process. The articles manufactured in this process have permanent antistatic properties and a high resistance to washing and cleaning.
