Abstract
A method of manufacturing 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.
Claims13
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.
