POLYMER-COATED WOVEN STRUCTURE MEANT IN PARTICULAR FOR GANGWAY BELLOWS FITTING TRANSPORTATION MEANS

摘要

The invention relates to a polymer-coated woven structure meant in particular to gangway bellows fitting urban transportation means. According to the invention, the woven structure is made up, both in warp and in weft, of polyethylene-therephthalate multifilament synthetic yarns with a length density of 1100 dtex, each of them comprising 192 filaments, with a twist of 120 tors/m in the Z direction, with a warp count of 105 yarns/10 cm, a weft count of 95 yarns /10 cm and a 1/1 weave, with a breaking strength of 2985 N/5 cm in the warp direction and of 2860 N/5 cm in the weft direction and is polymer-coated on both sides, the main polymer in the formula for coating the fabric already activated, for increasing the adhesiveness being the polyvinyl chloride, the mixture composition being the following: 63...65% polyvinyl chloride, 14.4...15.5% di(2-ethyl-hexyl)phthalate as a pliability increasing plasticizer, 17...19% antimony bloom as a fireproofing agent to increase the fire resistance, 2.3...2.7% titanium dioxide as an oxidation retarder to improve the resistance to ultraviolet rays.
