ABSTRACT:
In laminates composed of a woven or knitted fabric and a film impermeable to water and permeable to water vapor, the woven or knitted fabric is made of unstretched or partially stretched fibers. The laminates are highly extensible and retain the shape obtained by stretching. They are particularly useful as starting materials for intermediate layers in shoes and gloves and confer advantages over and above known laminates in respect to the manufacture and properties of the finished articles.
