Abstract of the Disclosure Hydrophilic polyolefin fibers may be prepared, for example, by discharging a heated and pressurized solution of an anionic polyolefin composition containing carboxylic functionality into a zone of reduced temperature and pressure, and then modify- ing the fibers so produced by treatment with an aqueous admix- ture of selected cationic and anionic water-soluble, nitrogen- containing polymers. Blends of the hydrophilic fibers with wood pulp provide paper products having improved physical properties.
