Abstract
Abstract A laminated, water-proof, elastic fabric which has the ability to pass moisture vapor therethrough, comprising a layer of stretch material (11) with substantial elastic qualities, and a polymere film layer (13), having a thickness less than about 1,0 mil, both are bound together by an adhesive (12) bonding layer being present in substantially discontinous segments, and a method for producing said laminated water-proof, elastic fabric, comprising the steps of providing a first layer of an elastomeric film, providing a second layer elongating the first layer a predetermined amount in the longitudinal direction and applying an adhesive at substantially discrete areas and pressing together and using the adhesive applied to the laminated fabric; see Figure 5.
