ABSTRACT:
The present invention is polysiloxane pretreated pulp fibers comprising pulp fibers, and a polysiloxane. The polysiloxane pretreated pulp fibers have a polysiloxane content of about 0.4 percent or greater by weight of dry pulp fibers, a silicone retention factor of about 0.6 or greater, and an initial water drop absorption value of about 180 seconds or less.
