Beschreibung
Zusammenfassung:	A nonwoven fabric having durable wettability comprises fibers formed from polyolefin blended with hydrophilic additives consisting of subunits of Formulae I, II and III: wherein x is an integer from 1 to 15; and R and R', which may be the same or different, each represent a branched or unbranched C1-18-aliphatic hydrocarbon group. Such fabrics have been found to provide surprisingly durable wettability. The preferred additive is a di-oleate ester of polyethylene oxide.
