ABSTRACT:
There is disclosed a nonwoven fabric laminate formed from an olefin copolymer, olefin terpolymer, or a blend of olefin polymers. Particularly, the improved fabric laminate is formed from a polymer having a crystallinity of less than 45% and preferably between 31-35% and most preferably about 32%. The fabric laminates formed from layers that are spun-bonded or melt-blown have improved characteristics including higher tear strength, greater tensile energy, greater abrasion resistance, better fabric drape and softness, and less particulate emission. There is also disclosed a low particle emission, sterilizable garment for use in clean rooms, paint rooms, and operating rooms.
