Description
Technical field
The utility model relates to textile technology field, especially a kind of double-deck air-tightness TPU membrane woven fabric.
Background technology
Air-tightness TPU (Thermoplastic polyurethanes) thermoplastic polyurethane film woven fabric is a kind of novel composite material for weaving with high-performance elastic, because of stretch-proof, wear-resisting, warping strength, the low temperature resistant and sealing property of its excellence, and be widely used in, on auto industry various footwear material bed material, decorations material and inflated article, there are wide market prospects.
Current air-tightness TPU membrane woven fabric can be divided into three kinds of structures: 1, substrate+TPU coating; 2, substrate+adhesive layer+TPU coating; 3, the first substrate+TPU coating+the second substrate; Above three kinds of modes all have easy to process, workable advantage, but also there is inherent defect.
1, substrate+TPU coating; The TPU coated fabric of this structure can adopt the methods such as dipping, painting is scraped, film lamination meets to prepare, according to the difference of base material, and the difference of TPU membrane performance, the air-tightness TPU woven fabric of multiple different properties can be prepared, but this composite peel strength is low, and fabric is short for service life.
2, substrate+adhesive layer+TPU coating; Be better than the air-tightness TPU membrane woven fabric of the first structure, this composite adds an adhesive layer between substrate and TPU coating, its peel strength is increased, stretch-proof, wear-resisting, warping strength low temperature resistant air-tightness TPU membrane woven fabric can be prepared, but the TPU membrane hardness adopted is comparatively large, makes the flexibility of composite material not good enough.
3, the first substrate+TPU coating+the second substrate; This composite respectively meets one deck substrate by " two cloth one films " i.e. TPU film both sides and forms.TPU membrane hardness conventional in the market is all greater than 65 degree, and this TPU membrane has good mechanical performance, and when hardness is lower than 65 degree, TPU membrane surfaces of tacky, is easily bonded together, and is generally not used in the surface treatment of woven fabric composite material.
Summary of the invention
