Definitions

  • the invention relates to a double-sided coated fabric comprising sheaths right through; it also relates to a process for the manufacture of such fabrics.
  • sheath is meant a continuous sheath possibly open at its ends, arranged in the very thickness of the fabric thus forming a passage for introducing any continuous element.
  • the cover must be load-bearing. It is therefore important to insert in this tarpaulin, for example every 60 or 80 cm, straps to avoid the floating of this tarpaulin and to ensure loading.
  • the invention overcomes these drawbacks. It targets a double-sided coated fabric comprising sheaths that are easy to manufacture, reliable, do not require special equipment and have excellent mechanical and textile properties.
  • This double-sided coated fabric comprising sheaths right through, is characterized in that it consists of: - A first tight coating support, coated on its external face with a first coating intended to form one of the two faces of said fabric; - a second coating support, coated on its external face with a second coating, intended to form the other face of said fabric, said second support having alternations: . portions with open texture, through which the external coating passes to adhere to the back of the first support and thus secure the two supports together, . portions with tight texture, which does not pass through said second coating and thus forming said sleeves.
  • the invention consists in making a double-sided coated fabric by superposition of two coating supports, one completely tight which will therefore not be crossed by the coating layer, the other having portions alternating network structure, therefore strongly open and through which the second coating layer to thus hang on the back of the first support, and tight portions not likely to be crossed by the second coating, thus forming sleeves, tubes, sheaths or the like.
  • the two coating supports are woven;
  • the open texture portions form a woven grid while the tight texture portions form a tight fabric that does not pass through the second coating;
  • the tightly woven portions are obtained by an increase in the grid of the density of the warp and / or weft threads;
  • the two coating layers are based on plasticized PVC;
  • the first support forms the right side of the coated fabric, while the second, which has open texture portions, forms the reverse side.
  • the invention also relates to a method for manufacturing a double-sided coated fabric comprising sheaths right through.
  • This process is characterized in that it consists: - first of all, to superimpose two fabrics respectively: . a first tight fabric in common use as a coating support, . a second fabric alternately having open texture portions and then tight texture portions; - Then, to cover this superimposed assembly with a plastic coating composition, respectively on the right side of the first fabric and on the reverse side of the second fabric; - finally, to gel the whole and roll up the coated fabric thus produced.
  • the assembly of the two superimposed tissues is kept under transverse tension, in particular by forceps , spikes or the like.
  • this transverse tensioning is carried out in accordance with the teachings described in patent FR-A-2,245,165 of the Applicant (known correspondent: US-A-4,052,521).
  • the double-sided coated fabric comprises two coated fabrics joined together, respectively a first coated fabric (1) intended to form the right side of the fabric and a second coated fabric (2) intended to form the face. towards.
  • This fabric has right through elongated sheaths (3,4) parallel to each other open at their two ends.
  • the first coated fabric (1) is composed in the order of a warp and weft fabric (5) with a tight texture of traditional use for the manufacture of tarpaulins, comprising for example warp and weft eight threads per centimeter of polyester 1100 Dtex 200 interlaced strands.
  • This tight fabric (5) is superimposed on a woven grid (8) whose characteristic is to present alternations: - On the one hand, heavily perforated portions (10) having a density of warp threads of seven threads / cm of polyester 1100 Dtex 200 strands twisted at 200 turns / meter; - And secondly, tight portions (11) intended to form the sleeves (3,4) having a density of warp threads of fourteen threads / cm, with the same characteristics as above; this grid (8) is woven by a polyester thread of the same characteristics but not twisted and interlaced; the density of the weft threads is four threads / cm, so that the finished unbleached fabric weighs about 135 grams per square meter.
  • the coating (9) is inserted between the contiguous non-contiguous warp threads, to come to stick against the reverse side of the first fabric tight (5). After gelation and cooling, the second fabric (8) is thus joined together with the first (5).
  • the coating layer (9) cannot penetrate. Thus, after gelation and cooling, the coating (9) does not pass through these portions (11). We then form a sheath (3,4).
  • the grid (8) is sufficiently perforated in the parts with open texture (10) to allow the coating composition (9) fluid to penetrate between the wires in order to cling to the reverse side of the first tight fabric (5).
  • the second fabric (8) which has portions (10) with open texture, can form the right side of the coated fabric.
  • the overlay (7) is applied to this fabric (8) and no longer to the fabric (1).
  • the fabrics are generally woven, they can also be knitted or the like.
  • the wires can be very varied in nature depending on the end applications envisaged.
  • This technique therefore makes it possible to conveniently produce double-sided coated fabrics having incorporated sheaths right through allowing the passage of straps or bungee cords (truck covers), rigid bars (blinds, curtains or sliding doors), or even any fluid.
