BREATHABLE PROTECTIVE FABRIC AND GARMENT.

摘要

A breathable composite barrier fabric for protective garments includes a high strength nonwoven web, a barrier layer and an aperture film layer, with the barrier layer between the high strength nonwoven web and the film layer. The different layers and webs may be bonded together to form the fabric using calendaring, thermal bonding and/or adhesives. The breathable composite barrier fabric is capable of blocking particles as small as 0.3 microns at greater than 99% efficiency while allowing air transmissions between 7 CFM and 9 CFM at 20 Pa. Protective garments may be constructed using the breathable composite barrier fabrics so that the high strength nonwoven web is on the body side of the garment and the film layer is on the exterior of the garment.
