AN IMPROVED FIBROUS PULP OF ORIENTED POLYETHYLENE FIBRIDS AND PROCESS FOR MAKING SAME

摘要

An improved pulp of oriented polyethylene fibrids is improved. The pulps have fibrids which average no longer than 1.2 mm, have a drainage factor of at least 2.5 sec/g, are capable of forming wet-laid sheets of uniform opacity and preferably have an agglomeration number of less than 2. The pulps are particularly useful as synthetic papers, in reinforced cement articles, in reinforced resin articles and in reinforced gaskets.
