Abstract
Microporous nylon materials which retain near constant time to hydrosaturation during and after heating to temperatures necessary for sealing together a plurality of surfaces, and the synthesis thereof. Nylon 46 dissolved into a mixture of liquid nylon 46 solvents and nonsolvents is dispersed on a fabric substrate, then precipitated to form a laminate, from which a wash removes the nonsolvents and forms the microporous material.
