Abstract
Methods are provided for producing a laminate particularly useful in producing warm moisture-resistant wearing apparel for industrial applications and sportswear. The laminate is superior in flexibility and comfort when worn while still providing appropriate moisture protection. In addition, the method includes procedures for providing a combined textured and creped surface for varying the appearance and degree of flexibility and "feel" to garments comprised of the laminate. The methods include joining a non-woven fibrous web such as a needled felt to a foamed synthetic resin web, such as polyurethane foam, and thereafter, through controlled tension, temperature and roll pressure, joining a film, such as a synthetic resin film, to the exposed foam surface through a heated roll nip, followed by embossing. The degree of "crepe" and texture or embossing imparted to the laminate varies inversely to each other, as desired, to provide a variety of different appearing and appealing fabric surfaces.
