Definitions

  • the present invention in its most general aspect, refers to a slide fastener.
  • the invention refers to a fluid-tight slide fastener, i.e. a slide fastener that is impermeable to fluids.
  • fluid-tight refers to a seal or material that is resistant to the passage of liquids, in particular water, and/or gases, for example air, even when put under a considerable pressure strain, for example a pressure difference between the interior and the exterior sides of a slide fastener of up to about 2 bars.
  • the present invention refers to a fluid-tight slide fastener of the type comprising a pair of impermeable tapes, each tape having a layered structure comprising an inner layer of a reinforcing textile material strip and an outer layer of fluid barrier material enveloping said inner layer, each tape also comprising a row of aligned teeth on at least a portion of one of the long edges thereof, said rows of aligned teeth facing each other and being associated to opposite stops, and a slider slidable between said stops for engaging in a fluid-tight way or disengaging said aligned teeth respectively.
  • the present invention also refers to a process for manufacturing a fluid-tight slide fastener as above.
  • slide fasteners comprise a pair of tapes of a textile material, each tape bearing a row of aligned teeth on at least a portion of one of the long edges thereof, said rows of aligned teeth facing each other and being associated to opposite stops, and a slider slidable between said stops for engaging or disengaging said aligned teeth respectively.
  • slide fasteners are required to be fluid-tight, to prevent the passage of fluids, in particular water, across the two sides of the tapes of the slide fasteners, yet both tenacious and pliable, to a certain extent.
  • multi-layered tapes composed of an inner layer of a reinforcing textile material enveloped in an outer fluid barrier material layer in such a way that none of the inner textile material is exposed to the surface, and to seal the aligned teeth on the outer fluid barrier material of the respective tapes so that the bonding which is formed between the teeth and the fluid barrier material is effectively fluid-tight.
  • thermoplastic elastomer material for the outer fluid-barrier layer of the tapes
  • thermoplastic material for the teeth are used for the manufacture of said fluid-tight slide fasteners.
  • these materials have proven to better meet most of the requirements that these products must satisfy, such as the above-mentioned impermeability and flexibility of the tapes, as well as their stability to light, resistance to sea water, and also easiness of sealing, gluing and stitching.
  • such materials can be efficiently worked in extrusion processes by which the layered structure of the tapes is formed and in injection overmolding processes by which the teeth are sealed to the tapes.
  • WO-A-02058500 discloses a slide fastener suitable for providing a water resistant closure between two edges of material.
  • slide fasteners of the above-described type exhibit a drawback in that they do not always show satisfactory mechanical properties, in particular at the interface between the inner layer and the outer layer of the tapes.
  • delamination This separation process, known as delamination, which is mainly due to a non-satisfactory adhesion between the materials constituting the inner and the outer layers of the tapes, causes the tapes to weaken and the inner textile material to become exposed to the surface, thus compromising the fluid-tight nature of the tape itself.
  • the technical problem underlying the present invention is that of devising and providing a fluid-tight slide fastener of the type considered above, which is reliable in the long run with regard to its fluid-tight nature as well as its structural integrity, so as to overcome the mentioned drawbacks with reference to the prior art.
  • a fluid-tight slide fastener comprising a pair of tapes, each tape having a layered structure comprising an inner reinforcing textile material layer enveloped in a fluid barrier layer made of a thermoplastic elastomer material (TPE), each tape exhibiting a row of aligned teeth made of a thermoplastic material on at least a portion of one of the long sides thereof, the rows of aligned teeth of said pair of tapes facing each other and being associated to top and bottom stops, and a slider slidable between said top and bottom stops for engaging in a fluid-tight way or disengaging said aligned teeth respectively, characterized in that said textile material for inner reinforcing layer of the tapes is chosen between polyester (PE), preferably polyethylene terephthalate (PET), polyamide (PA) and their blends or copolymers; said thermoplastic elastomer material for the fluid barrier material layer is chosen between a thermoplastic elastomer polyurethane (TPE-
  • thermoplastic elastomer material indicates specific materials, known per se, having a hard phase and a soft phase which confer thermoplastic properties and elastomer properties (flexibility) respectively. It includes block copolymers as well as blends comprising a thermoplastic material and an elastomer material.
  • said TPE-E is a polyether-ester block copolymer and said TPE-U is a block copolymer obtained from an ether and/or an ester and a isocyanate.
  • said thermoplastic material consists of a blend including PBT and polycarbonate (PC).
  • the PBT/PC weight ratio in said blend ranges between 70/30 and 30/70.
  • said thermoplastic material consists of a blend including acrylonitrile butadiene styrene (ABS) and a polyamide (PA).
  • the ABS/PA weight ratio in said blend ranges between 70/30 and 30/70.
  • the materials constituting the fluid barrier layer of the tapes and the teeth may include suitable additives such as, for instance fillers, pigments, binders and/or compatibilizers, the latter being incorporated to improve the physical and chemical affinity between said materials and/or between the materials used for the layered structure of the tape.
  • suitable additives such as, for instance fillers, pigments, binders and/or compatibilizers, the latter being incorporated to improve the physical and chemical affinity between said materials and/or between the materials used for the layered structure of the tape.
  • a fluid barrier layer of TPE-E is chosen in combination with teeth made of PBT.
  • a fluid barrier layer of TPE-U is chosen in combination with either a blend of ABS and PA or a blend of PBT and polycarbonate PC.
  • slide fasteners manufactured by using the selected materials have good mechanical properties at both the interface between the layers of the tapes and the chemical bonding between the fluid barrier layer of the tape and the teeth.
  • the layers are capable of reaching optimal values of adhesion to each other that are sufficient for withstanding the normal transfer of traction and shear forces through the contact interface which the slide fasteners are subjected to during their repeated use.
  • the thermoplastic elastomer material constituting the outer layer of the tapes confers a good flexibility to the tapes and exhibits a good adhesion by chemical bonding with the thermoplastic material constituting the teeth.
  • this improved adhesion between the selected materials of this invention is given by their physico-chemical affinity, as well as by the creation of strong chemical bonds at the surface of the materials to be joined in the operating conditions normally used for the manufacture of the tapes by extrusion and for the bonding between the tapes and the teeth by injection overmolding.
  • said inner reinforcing textile material layer of the tapes is made with a spun yarn of cut fibers.
  • the textile material of the inner reinforcing layer surface has an irregular, rough surface due to the use of cut fibers. More in detail, the ends of the cut fibers may protrude from the ideal diameter of the yarn, or the same fibers may form loops protruding from said diameter. This results in an irregular, non-smooth surface of the yarn, similar to natural-fiber yarns, while on the contrary common artificial or synthetic fibers yarns have a smooth surface.
  • cut fibers of selected artificial or synthetic textile material are used for the textile material of the inner layer, said fibers being obtained preferably by a cutting process, to imitate the surface of natural yarns.
  • a fastener with such inner textile layer has improved resistance to delamination. It is considered that improved resistance to delamination is due to said irregular, rough surface of the yarn, giving a stronger coupling with the fluid-barrier layer. More in particular, it has been found that ends or loops of the fibers, protruding from the ideal diameter of the yarn, remain embedded in the thermoplastic elastomer material of the fluid-barrier layer enhancing the resistance to delamination.
  • thermoplastic elastomer material is coupled to the textile layer in a melted state, and the above effect is obtained, i.e. irregularities of the surface remain trapped and embedded in the material of the fluid-barrier layer, thus yielding stronger coupling between the layers and improved resistance to delamination.
  • the slide fastener further comprises a layer of an adhesive between the inner textile material layer and the outer fluid-barrier material layer of the tapes.
  • the adhesive can be selected so as to have a high physico-chemical affinity for both the materials to be joined.
  • the adhesive comprises a polyurethane resin.
  • the present invention further relates to a process for manufacturing slide fasteners as described above. This process comprises the steps of:
  • the covering step is performed by extrusion or by lamination of the selected TPE onto the strips of textile material.
  • said teeth are obtained by injection overmolding of the selected thermoplastic material onto said longitudinal edge of each coated strip.
  • the process of the invention further comprises the step of sealing each tape at its short cut edge(s) with said fluid-barrier material. This may be carried out for instance while heat cutting said coated strips or by covering said short cut edge(s) with "fresh" fluid-barrier material.
  • said strips of a textile material are made with a spun yarn of cut fibers of an artificial or synthetic textile material, said fibers being obtained with a cutting process of continuous fibers, said yarn having natural fiber-like surface, i.e. an irregular, rough surface similar to those of yarns made of natural fibers.
  • said covering step is performed by extrusion or lamination of a selected TPE onto said spun yarn textile material of the strips, said TPE being in a melted state, so that the surface irregularities of the textile material remain embedded in the TPE layer.
  • said process further comprises the step of applying an adhesive layer onto the opposite surfaces of each textile material strip prior to covering said strips with said fluid-barrier material.
  • the adhesive application is preferably carried out by soaking each textile material strip in a dispersion of the selected adhesive in an organic solvent or by spraying said adhesive dispersion onto the opposite surfaces of each textile material strip.
  • the adhesive is then activated during the covering step of the textile material strips with a fluid-barrier material layer, which is performed for instance by extrusion.
  • a fluid-tight slide fastener is shown, in accordance with an embodiment of the present invention and globally indicated with 10.
  • the slide fastener 10 comprises a pair of tapes 12, substantially parallel to each other, each tape 12 being equipped with a row 20 of aligned teeth 21 on a central portion of the inner long edge 13a thereof, in a conventional manner, for example through injection overmolding processes.
  • said rows 20 of aligned teeth 21 face each other and are associated to two stops, namely a bottom stop 24 and a top stop 26, positioned at a set distance from each other along said row of aligned teeth.
  • a slider 22 is slidable between the bottom stop 24 and the top stop 26, for engaging in a fluid-tight way or disengaging the aligned teeth 21 of said rows 20, respectively.
  • the slider 22 comes to the end of its opening stroke at the bottom stop 24, thereby disengaging the aligned teeth 21 of said rows 20 whereas the slider 22 comes to an end of its closing stroke at the top stop 26 thereby engaging in a fluid-tight way the opposite aligned teeth 21 of said opposite sets 20.
  • the bottom stop 24 is in form of a single piece applied on both the tapes 12 at the lower ends of the rows 20 of aligned teeth 21, whereas the top stop 26 comprises two half-portions, each half-portion being applied on a respective tape 12 at the upper end of the respective set 20 of aligned teeth 21.
  • top stop 24 and the bottom stop 26 to the tapes 12 can be carried out in a per se conventional manner for example through injection molding.
  • the tapes 12 are joined in a fluid-tight way along a portion 25 of the respective inner long edges from the rows 20 of aligned teeth 21 and comprising the bottom stop 24.
  • the portion 25 extends from the lower ends of said rows 20 of aligned teeth 21 up to the lower short edges 13b of the tapes.
  • each tape 12 comprises an inner reinforcing textile material layer 14 enveloped in an outer fluid barrier material layer 16.
  • the tape 12 is formed by either extrusion techniques or lamination and the fluid barrier material layer 16 entirely covers the inner textile material layer 14 so that no part of the inner textile material 14 remains exposed.
  • said inner textile material layer 14 is made of fibers of PE, preferably PET, PA or their blends or copolymers and said fluid barrier material layer 16 is made of a thermoplastic elastomer material chosen between TPE-E and TPE-U.
  • Said inner textile material 14 made out of woven or nonwoven fibers, confers the tape a certain degree of pliability. It is important, in fact, that the slide fastener can be bent and adapted to the shape of the item onto which it is applied without it cracking, snapping or otherwise getting damaged or generating an encumbrance to the item onto which it is applied.
  • said textile material 14 made of spun yarns of cut fibers of an artificial or synthetic textile material.
  • Said yarn has an irregular, rough natural-like external surface, due to the use of cut fibers.
  • said outer fluid barrier material layer 16 is fully compatible with the inner textile material layer 12 so that, upon manufacture by extrusion or lamination, the two layers undergo an interaction which brings about a strong and solid adhesion between them.
  • said aligned teeth 21 of the rows 20 are made of a thermoplastic material chosen among polybutylene terephthalate (PBT), acrylonitrile butadiene styrene (ABS), polyamide (PA) and their blends or copolymers.
  • PBT polybutylene terephthalate
  • ABS acrylonitrile butadiene styrene
  • PA polyamide

  • the tape 12 also includes two layers of an adhesive (layers 30 and 31) applied on the opposite (top and bottom) surfaces of the textile material layer 14. In the areas where the adhesive is present, the textile material layer 14 and the fluid-barrier material layer 16 are then joined indirectly by a strong chemical bonding between the adhesive molecules and the materials constituting the textile layer 14 and the fluid-barrier layer 16, which allows to avoid delamination of said layers 14 and 16.
  • Strips of PE fibers were fully coated with a layer of fluid-barrier material (a TPE-U material) by means of a conventional extrusion head.
  • the extrusion of the fluid-barrier material from said head was performed in a conventional way according to the procedure suggested by the manufacturer.
  • the coated strips were then equipped each with a plurality of rows of aligned teeth along a longitudinal edge thereof, said rows being set at a predetermined distance to each other.
  • the teeth were each made from a blend of ABS and PA.
  • the teeth application was performed by injection overmolding the teeth material onto said longitudinal edge of the coated strips in a conventional way (according to the procedure suggested by the manufacturer).
  • the coated strip equipped with said rows of aligned teeth were then heat cut transversally along consecutive rows of aligned teeth to obtain a plurality of tapes of the same dimensions, wherein each tape was equipped with a row of aligned teeth.
  • the slide fasteners so obtained were tested for their resistance to delamination of the layered structure of the tapes before and after each of repeated washing cycles (up to five washing cycles).
  • Each washing cycle of the slide fasteners was carried out in a conventional washing machine at a temperature of 40°C for about 1 hour and 30 minutes using appropriate detergents.
  • the resistance tests were carried out as follows. Each sample to be tested was engraved on its surface so as to peel (raise) a small rectangular portion (about 15 x 40 mm) of the said fluid-barrier layer from the respective tape. Then, the small rectangular portion of the fluid-barrier layer and a free end portion of the tape (in the direction opposite to that of peeling) were clamped in two opposite flat clamps of a dynamometer respectively and the sample was put perpendicularly to the flat clamps.
