Abstract
A method of producing a stretchable coated fabric having waterproof or like characteristics of particular application to the manufacture of protective clothing is proposed wherein plural layers of a coating material are applied to a carrier element having release characteristics relative to the material of the layers, and such layers are laminated to a stretchable textile fabric comprising continuous filament yarns by utilizing the tension in the carrier element to provide a laminating pressure.
Claims14
A method for the production of waterproof stretchable coated textile fabrics comprising the steps of:
- (a) applying plural layers of coating material to an elongate, flexible carrier element having a release capability in relation to the coating material, the respective formulations of the successive layers and the application thereof to the immediately preceding layer existing on the carrier element being such that a given coating layer will fuse with the free surface and immediately adjacent parts of such preceding layer;
- (b) contacting a surface of a length of a textile fabric formed wholly of continuous filament synthetic yarns with said layers of coating material on said carrier element, and
- (c) tensioning a run of said carrier element carrying said layers and a textile fabric run so that said textile fabric run is also tensioned, the tensioning of said carrier element run creating laminating pressure between said textile fabric run and said carrier element run so that said layers are transferred to the textile fabric and said layers and textile fabric are laminated together to form a laminate.
