Abstract
Wettable fibers and/or filaments, especially those of fine denier, are prepared from olefin polymers, especially linear low density copolymer (LLDPE), by having incorporated 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 tri-glyceride, or (b) a polyoxalkylene fatty acid ester, or (c) a combination of (b) and any part of (a) above.
Claims49
Wettable fibers or filaments prepared from a composition comprising an olefin polymer having incorporated therein a wetting agent, said wetting agent comprising at least one of (a) an alkoxylated alkyl phenol along with, or in combination with, a mixed mono-, di- and/or tri-glyceride, or (b) a polyoxyalkylene fatty acid ester, or (c) a combination of (b) and any part of (a).
Wettable fibers or fine filaments prepared from a composition comprising an olefin polymer having incorporated therein a wetting agent, said wetting agent comprising at least one combination of:
- (a) an alkoxylated alkyl phenol along with a mixed mono-, di-, and/or triglyceride;
- (b) an alkoxylated alkyl phenol along with a polyoxyalkylene fatty acid ester;
- (c) a polyoxyalkylene fatty acid ester along with a mixed mono-, di- and/or triglyceride;
- or
- (d) an alkoxylated alkyl phenol along with a mixed mono-, di-, and/or triglyceride and with a polyoxyalkylene fatty acid ester.
