Definitions

  • the invention relates to a method for manufacturing a coated fabric; it also relates to the coated fabric produced in this way.
  • coated fabrics in particular those which are intended for the manufacture of tarpaulins for trucks and more particularly for the manufacture of side sliding curtains for trucks, there is essentially a search for tear resistance, in particular for primed tear, since the resistance to traction is very largely sufficient.
  • the basic support fabric generally made of synthetic fibers
  • this resistance is notably degraded because, inter alia, the threads elementary are blocked in the new structure.
  • this resistance to tearing started going from fifty kilos and more for the unbleached support fabric, to only eight kilos for the same fabric after coating.
  • the most widely used solution on the industrial level consists in increasing the number of wires or the size of these wires, or both at the same time, or even in making them work with special "plaited” type armor called also "Panama". It is thus possible, under the most favorable conditions, to double the resistance to primed tear, but by unnecessarily increasing the weight of the raw materials, therefore the price of the support, as well as the thickness, therefore the total weight of the fabric. The increase in the tear obtained remains nevertheless insufficient.
  • the invention overcomes these drawbacks. It relates to a process for the production of coated fabrics which is economical, easy to carry out and which leads to fabrics exhibiting quite unexpectedly tear resistance properties, primed in particular, very markedly improved, without however that the other properties, in particular of tensile strength, be degraded, some of these other properties, such as adhesion, being even also improved.
  • This process for the manufacture of a woven warp and weft woven fabric, in which the support fabric comprises fugitive chemical weft threads, and in which this fleeting weft yarn is subsequently removed without affecting the other threads, is characterized:
  • the "weave" of a designated fabric is the mode of interweaving of warp and weft threads.
  • the rhythm of an "armor” is the enunciation of the threads that are taken and the threads that are left successively in each pick.
  • a technician will easily be able to see where it should be placed in weft the fleeting thread, so that after disappearance in the fabric of this fleeting weft thread, we no longer obtain a woven fabric, that is to say in which the warp and weft threads are intertwined, but on the contrary, a superposition of plies of threads parallel to each other, crossed between them, in particular orthogonally, respectively in order a first ply of threads parallel to the warp, in the middle a second ply of threads parallel to weft orthogonal to the first ply, a third ply of weft threads parallel to the first, but whose threads are offset from those of the first ply.
  • the fleeting thread is advantageously of the same chemical nature as the coating.
  • a PVC coating will be used.
  • copolyamide yarns with a low melting point it is possible to use polyamide coatings.
  • Polypropylene yarns or better still polyethylene yarns with a low melting point can be used advantageously with coatings based on polyolefin.
  • the fleeting weft thread can be mono- or multifilamentary, or even made of fibers.
  • so-called second choice yarns are advantageously used.
  • the title of the fleeting thread is as fine as possible, while remaining compatible with the smooth running of the looms.
  • Example 1 is repeated with only one variant, namely that, in the weft, the texture is modified, namely twelve strokes per centimeter distributed in groups of two under the step, at the rate of two polyester threads 2200 dtex / 420 strands without twist and two yarns of chlorofibers Nm 2/40.
  • the texture is modified, namely twelve strokes per centimeter distributed in groups of two under the step, at the rate of two polyester threads 2200 dtex / 420 strands without twist and two yarns of chlorofibers Nm 2/40.
  • the weft there is successively a group of two chlorofiber yarns, then a group of two polyester yarns.
  • chlorofibres which tend to shrink cannot do so because of the transverse tension applied during pregelling, as during gelling. As is known, these wires decompose at 175-180 0 C.
  • the ecru fabric 185 cm wide, weighs 210 g / m 2 .
  • a plastisol of PVC is coated under the same conditions as in Example 1, taking care to first deposit an undercoat on each side of the fabric about IOOg / m 2 , then ending with a coating of the same plastisol composition on the abrasion layer. As said in Example 1, throughout the coating treatment, the fabric was held tightly in the weft direction.
  • the finished fabric weighs 680 g / m 2 and after franking of selvedges has a width of 180 cm, which shows that there has been practically no shrinkage in the direction of the weft.
  • the tensile strength of this fabric is in the warp direction of 300 kg and in the weft direction 300 kg.
  • the resistance to initiated tear is measured under the same conditions and greater than 50 kg, the upper limit of the tear meter used.
  • the adhesion also measured on five-centimeter strips is 20 kg.
  • the fabric obtained weighs approximately 700 g / m 2 , has a width of 180 cm, a tensile strength also of 300 kg in each warp and weft direction, but has only an initiated tear of eight kilos (against fifty) and an adhesion of ten kilos (against twenty).
  • Example 4 is repeated by alternately placing one out of two chlorofibers in the chain, as taught in French patent FR-A-1 457 488 cited in the preamble.
  • the fabrics produced in accordance with the invention are essentially characterized by a very markedly improved resistance to tearing, notably initiated. In this way, they can be advantageously used for making the sliding curtains of tarpaulins for trucks, fabrics for containers, for silos, conveyor belts, ventubes, cut fabrics for straps, fabrics for inflatable structures.
