Definitions

  • the present application relates to a textile covering specially designed for constitute the interior trim of a motor vehicle, more particularly the appearance of the roof pavilion, the top cabinet, the sun visor and sunroof.
  • An interior trim for motor vehicles is made so that conventional, by three-dimensional deformation, in particular drawing, of a complex structure which is formed by the superimposition of an aspect coating and a stiffening support, a foam possibly being interposed between the appearance coating and said support.
  • the making of this filling consists first of all of the superimposition of the elements constitutive planes of the complex structure, then in a second time to deform three-dimensionally this structure, in particular by stamping, so to obtain the configuration suitable for the motor vehicle in which the trim must be placed.
  • the appearance coating must therefore be able to withstand these three-dimensional deformations.
  • a scraped knit currently offered on the market is of the order of 130 g / m 2 and is obtained on a knitting loom two gauge bars 28 from yarns, the titration of which is of the order of 50 dtex.
  • the first drawback is the risk of piercing by the glue of the knitting during the operation consisting in joining by gluing the knitting and stiffening support.
  • the second disadvantage consists in the decrease in the property of the lining in terms of resistance to use and especially in the light.
  • the goal that the applicant has set is to offer a knitted knitted fabric intended for constitute the appearance coating of an interior trim for vehicles automobiles which overcome the aforementioned drawbacks.
  • the scraped knit of the invention is obtained on a two-bar loom powered by a first ground wire and a second scratch wire, the two so-called wires with a titration between 17 and 44 dtex.
  • the first ground yarn had a count of 22 dtex and the second yarn of 33 dtex, the knitted fabric making 75 g / m 2 .
  • the mesh density per cm is between 20 and 30.
  • the length of absorbed wire (LFA), being a loom knit two bars is 40 to 55 for the first bottom thread and 50 to 75 for the second strand, in centimeters for 240 stitches.
  • the knitting is subjected to a fine scraping, that is to say that the threads scrape are very little raised relative to the bottom thread.
  • the extra thickness caused by the lifting of the scratching wires can be of the order of 0.1 to 0.3 mm.
  • the binding mode is as follows: I II 0 2 1 3 - - 2 1 1 0
  • the loom was adjusted so as to obtain a density of 25 meshes per cm.
  • the length of absorbed wire was 46 for the wire feeding the first bar (B I) and 62 for the second bar (B II).
  • the knitting Before scraping, the knitting underwent various finishing operations. In an example precise, it was a first washing operation, including a prefixing, a second autoclave dyeing operation and a third operation including softening on a scarf and drying on an oar.
  • the knitted fabric thus treated is passed through a specially adjusted scraping installation. to make it undergo a fine scraping, that is to say a scraping during which the uplift of the scraping wires, compared to the bottom wires is relatively low.
  • This increases the thickness of the knitted fabric in the range of 0.1 to 0.3 mm. It is also important that the scraping effect obtained is very uniform over the entire surface of the knitted fabric.
  • the knitted fabric was subjected to a complementary heat-fixing operation on the oar.
  • the knitted fabric had a weight per m 2 of 75 g.
  • This brushed knit was used in the manufacture of an interior trim for automobile of which it constitutes the appearance coating, for this purpose the superimposition of the various constituent elements of this garnish, the scraped face knitting constituting the outer face of this superposition. Brushed knitting is in particular secured to the element which is adjacent to it by adding glue.
  • This overlay comprises at least one stiffening support which is capable of being deform under pressure, hot and rigidly keep the configuration which is given to it during this deformation.
  • the knitted fabric will itself deform and present, depending on the configuration of the lining, areas in extension and areas in compression. These are the fittings intended for top-of-the-range cabinetmaking which generate the areas with the maximum extension and for which the risks of glue piercing and the risks of degradation by light are the greatest. It is for this application that the knitting of the invention proves to be most effective.
  • the present invention is not limited to the preferred embodiment which has been described by way of non-exhaustive example.
