Abstract
A protective garment made of material which includes a high barrier, multi-layer film incorporating EVOH laminated to a spun bonded polyester substrate. The film is a five layer construction with a layer of EVOH in the middle, bracketed by water resistant bonding resin layers and outer layers of polyethylene or polyester. The substrate is formed with low temperature binders and is calendered on both sides, the outer side being calendered much more extensively than the inner side. The material is joined together at pattern edges by thermal bonding under pressure or by a strip of the film thermal bonded to material segments.
