Abstract

Aqueous suspensions of polyolefin fibrids are prepared. To avoid foam formation and improve fiberbonding, small amounts of anionic agents are added to the suspensions. The suspensions are suitable for the manufacture of paper-like or textile-like web structures distinguished by very good fiber bonding and good initial wet strength.
