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.
