- 27 Fluid-tight slide fastener (10) comprising a pair of tapes (12), each tape (12) having a layered structure comprising 5 an inner reinforcing textile material layer (14) enveloped in a fluid barrier layer (16) made of a thermoplastic elastomer material (TPE), each tape (12) exhibiting a row (20) of aligned teeth (21) made of a thermoplastic material on at least a portion of one of the long sides (13a) 10 thereof, the rows (20) of aligned teeth (21) of said pair of tapes (12) facing each other and being associated to opposite stops (24,26), and a slider (22) slidable between said opposite stops (24,26) for engaging in a fluid-tight way or disengaging said aligned teeth (21) respectively, 15 characterized in that said textile material for the inner reinforcing layer (14) is chosen among polyester (PE), preferably PET, polyamide (PA) and their blends or copolymers; said thermoplastic elastomer material (TPE) for the fluid barrier layer (16) is chosen between 20 thermoplastic elastomer polyurethane (TPE-U) and thermoplastic elastomer polyester (TPE-E), and said thermoplastic material for the teeth (21) is chosen among polybutylene terephthalate (PBT), acrylonitrile butadiene styrene (ABS), polyamide (PA) and their blends or 25 copolymers. 13b 26 13a 13b 22 13a 13a 12 Fig.1I 25 //13a 13b 13b 13b 1 Fig.2 |
