<p>1. A process for laminating a textile material with a polyvinyl fluoride film comprising:… preparing a polyvinyl fluoride dispersion (15) from a polyvinyl fluoride resin and a latent solvent so as to have a solids content of from 5 to 50%, by weight,… coating a heated belt surface (21) (22) with said polyvinyl fluoride dispersion to a thickness that will give a dried film thickness not exceeding 25 mu m while maintaining the belt surface temperature adequate to heat the dispersion to a temperature high enough to gel the dispersion but below the fusion temperature of the resin,… forming a gelled, coalesced polyvinyl fluoride film layer on the heated belt surface and maintaining contact with the heated belt surface long enough to remove enough of the latent solvent to coalesce the polyvinyl fluoride layer to form a cohesive gel,… passing the textile material (10) adjacent to the cohesive gel so that the cohesive gel adheres to the textile material, and… passing the textile material with the adhered cohesive gel into a nip point (33) (34) so as to form a laminate (35) of the textile material with the adhered cohesive gel and heating said laminate to temperatures high enough to fuse said polyvinyl fluoride film layer.</p> |
