Abstract
Abstract Wettable fibers and/or filaments are prepared from olefin polymers, especially linear low density copolymer (LLDPE), by incorporating into said olefin polymer at least one wetting agent of the group comprising (a) an alkyoxylated alkyl phenol along with a mixed mono-, di-, and/or triglyceride, (b) a polyoxalkylene fatty acid ester, or (c) a combination of (b) and any or all parts of (a).
