Abstract
A flexible non-porous laminate film structure is provided comprising a textile substrate having a fluorinated film laminated thereto, which is laminated at a temperature lower than the softening point of the predominant polymeric component of the fluoropolymer fiber. The resulting product is resistant to delamination.
Claims35
A flexible, non-porous laminate film structure comprising a textile substrate formed of fluoropolymer fibers, and at least one fluoropolymer film layer, wherein the fluoropolymer film layer is intimately bonded to the textile substrate and material from the fluoropolymer film layer fills voids between at least some of the fibers of the substrate.
A method of manufacturing a flexible non-porous film comprising:
- providing a fluoropolymer film layer of a first material and providing a textile substrate formed of fluoropolymer fibers of a second material, wherein the first material has a lower melting point than the second material;
- and
- laminating the fluoropolymer film layer and the textile substrate at a temperature that is between the melting points of the first material and the second material to produce a flexible non-porous film.
