ABSTRACT:
A barrier fabric laminate for use as a cover for a gel filled article is provided. The barrier fabric laminate comprises a fluid impermeable film and a polyurethane nonwoven web which has a friction value of less than 200 g and a fabric hand of less than 200 g. The polyurethane web is formed from fibers of less than about 50 .mu.m diameter on average and is preferably formed with a fluorochemical melt additive by sequentially melt blowing the polyurethane web on a heated collecting drum and laminating in the nip formed by a heated nip roller and the collecting drum.
