Beschreibung
Zusammenfassung:	There is provided a nonwoven fabric having durable wettability comprising fibers formed from polyolefin blended with hydrophilic additives of the formula; wherein x is an integer from 1 to 15 and R is an alkane or alkene with up to 18 carbon atoms, A, B, and C are integers equal to or greater than one arranged in any order or repetitive series, z is an integer at least equal to one, and wherein the fibers which have been formed are polyolefin provided with hydrophilic additives prior to fiberization. Such fabrics have been found to provide surprisingly durable wettability.
