ABSTRACT:
Microporous polymeric material such as elastomeric polyurethane laminated to fibrous fabric by fusing projections integrally formed on such microporous material the projections being spaced or in an open pattern. The lamination may be effected by applying a flame to the projections or by otherwise supplying heat thereto to make them tacky and then pressing the fabric and tackified projection-carrying surface against each other to embed surface fibers of the fabric into the spaced tacky material.
