摘要：
Hydrophilic polyolefin fibers are prepared by treating an anionic fibrous polyolefin composition containing carboxylic functionality with an aqueous admixture of selected cationic and anionic water-soluble, nitrogen-containing polymers. The anionic polyolefin composition may, for example, be a pololefin containing carboxyl groups which have been introduced into the polymer molecule by grafting the polyolefin with a monomer-containing carboxylic functionality or by oxidizing the polyolefin with oxygen or ozone or the composition may be a polyolefin in admixture with an anionic polymer containing carboxylic functionality.
Blends of the hydrophilic fibers with wood pulp provide paper products having improved physical properties.
