ABSTRACT:
There is provided a laminate of nonwoven fabrics for barrier applications which has improved ratios of barrier and strength to weight, of softness to strength and of vapor transmission to barrier. The laminate has a meltblown layer sandwiched between spunbond layers to produce an SMS laminate. The meltblown and spunbond layers may have between 0.1 to 2.0 weight percent of a fluorocarbon and the meltblown layer preferably between 5 and 20 weight percent polybutylene. The laminate also may have pigments if desired. Such laminates are useful for garments.
