The fabric is a film material with high strength and good flexibility, and is a coated fabric formed by compounding a fabric material and a coating. The currently commonly used film materials are divided into the following materials according to the different coating materials: 1) PVC film material: is compounded by a polyvinyl chloride coating and a polyester fiber (terylene) base layer; 2) PTFE membrane material: a composite film material formed by coating Polytetrafluoroethylene (PTFE) on a base cloth woven from ultrafine glass fibers; the fire-proof and flame-retardant coating has the greatest characteristics of high strength, good durability, fire resistance, good self-cleaning property and no influence of ultraviolet rays; 3) PVDF membrane material: the PVC membrane material is a membrane material which is formed by coating polyvinyl chloride on a base cloth woven by polyester fibers and then adding a 100% polyvinylidene fluoride (PVDF) surface coating, and is the most widely applied at present due to the excellent cost performance, low raw material cost, good tearing strength and excellent processing flexibility of the PVC membrane material.
The traditional terylene PVC film material generally consists of a base layer and a coating layer, wherein the film material is prepared by uniformly coating polyvinyl chloride resin or emulsion on a cloth substrate, baking and melting (heating until a paste layer is completely melted and molded and is uniformly and tightly attached to the cloth substrate), and cooling. The PVC film is usually laminated by hot pressing, a PVC film and polyester woven cloth are directly laminated under certain pressure and temperature, and the calendered film can be prepared by cooling. Generally, the method requires applying a layer of adhesive to the surface of the base fabric, and then applying heat and pressure to both the base fabric and the PVC film. The products of the existing hot-pressing laminating method mainly comprise double-layer hot-laminating film materials.
