Abstract:
1. A biodegradable fibrous web comprising biodegradable polymer fibers, wherein the biodegradable polymer fibers comprise polylactic acid, the web having a durable hydrophilic surface coated with a hydrophilic polymeric material in an amount of from about 0.01 to about 2.0 percent by weight, based on the dry weight of the web; in which the hydrophilic polymeric material is a cellulose derivative, the cellulose derivative selected from the group consisting of hydroxyethyl cellulose, hydroxypropyl cellulose, methyl cellulose, ethyl cellulose, methyl hydroxypropyl cellulose, ethyl hydroxyethyl cellulose, carboxymethyl cellulose, or a combination thereof; wherein the hydrophilic polymeric material will not significantly suppress the surface tension of an aqueous medium with which the web may come in contact.
