Abstract

A method of treating a low hydrohead fibrous porous web material to increase its retentive wettability, by at least about 50%, as compared to untreated low hydrohead web material, is disclosed. The increase in retentive wettability is evidenced by the increase in the average number of runoff tests that the treated web material can sustain without unacceptable runoff is disclosed.
The invention is also directed to products prepared or preparable by the process.
