Abstract

A protective sleeve includes a plurality of cords braided together. Each of the plurality of cords is formed from yarn that are knitted together. The plurality of cords form a substantially complete external surface of the protective sleeve.

Description

  • The present invention refers to a protective sleeve, specially designed for protecting cables in automobiles. The present invention also refers to a method for manufacturing said protective sleeve.
    • BACKGROUND OF THE INVENTION
  • In the automobile industry the automobile cables are covered with textile protective sleeves. These protective sleeve must have thermal and mechanical protective features.
  • Usually, these protective sleeves are formed from a plurality of yarns knitted to each other with different materials and features, according to their particular application. Furthermore, if necessary, these protective sleeves can be covered with any material that provides any enhancement to their features.
  • However, in the practice it has been shown that in case of an impact on the automobile, the protective sleeves currently known cannot protect completely the cables housed inside them.
  • It must be pointed out that protective sleeves are known that comprise braids formed by yarns, see e.g. EP-A-1 119 656 and U.S. Pat. No. 5,744,206. However, the braids included in these protective sleeves only cover a limited portion of the sleeve surface, because their end is not to protect mechanically the cables that are housed inside it, but to provide a space between the internal surface of the sleeve and the cables inside it. Therefore, these known sleeves are suitable to provide thermal protection, thanks to the air chamber defined inside the sleeve by said braids or cords.
    • DESCRIPTION OF THE INVENTION
  • With the protective sleeve and the method of the invention said drawbacks can be solved, presenting other advantages that will be described.
  • According to a first aspect, the present invention refers to a protective sleeve comprising a plurality of yarns and/or cords knitted to each other, that is characterised in that said cords are formed by textile structures that are bound to each other and cover in a substantially complete way the external surface of said sleeve.
  • Advantageously, the yarns of said cords are from polymeric material, aramid, metal, polyethereherketone (PEEK), glass fibres and/or silica derivates, or any material that can be knitted.
  • The yarns of said cords can be straight or textured multi-filaments twisted or non-twisted and/or mono-filaments, which have a circular, oval or rectangular cross-section, or with any other suitable shape.
  • Preferably, the linear density of the yarns of said cords is from 10 dTex to 10,000 dTex.
  • The cords preferably has a round, square or rectangular cross-section, with a thickness from 0.5 mm to 35 mm.
  • Regarding the sleeve, its diameter is from 1 mm to 500 mm, and the thickness of the sleeve wall is from 0.5 mm to 50 mm. If wished, said sleeve can be finished with silicone, polyurethane, resin, acrylics, or any suitable finish.
  • According to a second aspect, the present invention refers to a method for manufacturing the protective sleeve previously cited, that is characterised in that comprises the following steps:
      • knitting a plurality of yarns to form a plurality of cords;
      • braiding said plurality of cord to form said sleeve.
  • Said knitting of said yarns to form the cords can be done by twisting, folding, braiding, knitbraiding, warp knitting, weft circular knitting, flat bed knitting, weaving and/or non-woven fabrics.
  • On the other hand, the braiding of said plurality of cords to form said sleeve is done by braiding inserting the cord as a straight yarn, braided braiding the cord, warpknitting inserting the cord on Raschel machines, knitting or laying the cord, knitting in narrow fabric machines wefting the cord or inserting the cord or both at the same time, and/or flat bed knitting inserting the cord, knitting or laying the cord.
  • It must be pointed out that the sleeve can be done integrally from cords braided to each other, or mixing cords and textile material.
  • The method can comprise, if whisked, an additional step of finishing with silicone, polyurethane, resin, acrylics or any suitable finish.
  • The protective sleeve has the main advantage that provides a great resistance to impacts, protecting completely the cables housed inside it. E.g. in case of an impact in an automobile, the protective sleeve of the present invention resists absorbing said impact and it does not affect the cables housed inside it.
