A method for treating the surface of hydrophobic polyolefin-containing fibers to improve their lubricity and antistatic properties comprises applying a liquid lubricating finish to the surface of an extruded polyolefin-containing fiber or filament, in which the finish is either (1) a polyol, (2) a water-soluble ester or polyester obtained by reacting the polyol with a fatty acid having up to 6 carbon atoms, or (3) a glycol obtained by reacting the polyol with ethylene oxide or a combination of ethylene oxide and propylene oxide, and then mechanically processing the fiber or filament, the finish providing lubricity for the processing operations and lacking sufficient lipophilic substituents to produce significant surfactant properties; and the use of the said finish. |
