Abstract
A method of making garment material, the method having the steps: applying coagulant (34) to a substrate (32); applying a foam (38) of the polymeric material to the substrate (32); allowing the coagulant (34) to coagulate some of the foam (38); and removing uncoagulated foam (38) from the substrate (32) to leave a layer of coagulated polymeric material on the substrate (32).
Claims18
A method of making garment material, the method having the steps:
- fitting a substrate onto a mould;
- applying a coagulant to the substrate and then applying a layer of foam of a polymeric material to the substrate;
- allowing for the coagulant to coagulate some of the foam for a controlled period so that an underside of the layer of foam polymeric material, which is closest to the substrate, coagulates to form a coagulated layer and an outer part of the foam layer does not coagulate and forms an uncoagulated layer;
- removing the uncoagulated foam layer before a film skin can form on the layer of foam, to leave a cohesive, porous, and breathable coagulated layer of polymeric material on the substrate, wherein the controlled period is such that the garment or garment material when subjected to a temperature of 20+2° C. and a relative humidity of 65±2% for 265 minutes, will hold between 1.0 mg and 8.5 mg of water per cm2 of the garment material;
- and
- removing the garment material comprising the substrate and the coagulated polymeric material from the mould.
