ABSTRACT:
There is disclosed nonwoven composite fabric comprising a central melt-blown web preferably formed of collected, entangled, elastic or adhesive nonwoven fibers comprising poly (ethylene-vinyl acetate), where the central web is polar and of relatively low melting point. This central web is positioned next to or bonded to two other insulative nonwoven webs of non-polar, melt-blown fibers, which in turn are positioned next to or bonded to two outer nonwoven webs of spun-bonded fibers. The composites are useful for health care fabrics such as drapes, protective covers, and the like.
