BREATHABLE COMPOSITE BARRIER FABRIC AND PROTECTIVE GARMENTS MADE THEREOF.

摘要

A breathable composite barrier fabric for protective garments including a low-strength nonwoven web; a high strength nonwoven web containing multicomponent fibers that have a first polyolefin component and a second polyamide component, the high strength web having a grab tensile strength of at least 1.5 times the low strength web; and a water impermeable barrier layer positioned between the low strength web and high strength web, the webs and barrier layer being joined by thermal bonding. Protective garments may be constructed from the breathable composite barrier fabrics. The low strength nonwoven web is on the bodyside of the garment and the high strength nonwoven web is on the exterior of the garment.
