Abstract
Point-bonding and water-jet-softening of a sheet of flash-spun polyethylene plexifilamentary film-fibril strands provide a nonwoven fabric that is particularly suited for use in disposable protective garments. Garments made with the nonwoven fabric are comfortable and provide a good protection against particulate matter, such as air-borne asbestos particles.
