Abstract

A condrapable hydrophobic nonwoven web of continuous fibers includes a hydrophobic nonwoven web of continuous fibers, and a fiber surface-modifying agent on the web to form therewith a condrapable hydrophobic web. The agent is essentially an amino-modified polydimethylsiloxane. The condrapable hydrophobic web is characterized by a substantial hydrophobicity, as measured by a strike-through of over 180 seconds and by a substantial increase in condrapability, as measured by a Handle-O-Meter decrease of at least 15% average for MD and CD.
