Abstract
A composite material adapted for barrier garment applications is made by laminating a film with an amorphous polymer layer to a prebonded nonwoven web under conditions producing laminate bonds corresponding to the prebond locations, and unbonded areas between the bonds while maintaining constant film thickness. The composite has enhanced resistance to viral penetration for use as a surgical gown material, for example, and also desirably has a MVTR of at least about 300 g/m,/24 hours and a hydrohead of at least about 50 mbar. In use as a component of a protective apparel such as a surgical gown or drape, the composite provides comfort and protection with reduced risk of film damage.
