Waterproof and breathable multi-layer material

Abstract

A waterproof and breathable multi-layer material. The multi-layer material allows moisture transmission to prevent moisture accumulation and maintains resistance to liquid water penetration even when the interior surface of the multi-layer material is exposed to surface tension-reducing substances. The multi-layer material comprises a flexible textile layer and at least one layer of ultra-high molecular weight polyethylene (UHMWPE) porous membrane configured to block liquid water penetration and allow moisture transmission through the porous membrane. The porous membrane forms a barrier to prevent surface tension-reducing substances from passing through and avoids their entry into the textile layer. The method of preparing said multi-layer material is also disclosed.
