Definitions

  • the present invention relates to a fabric, e.g. to be used to provide reinforcement or cut-resistance to protective textiles, such as e.g. clothing, canvasses, tents, tarpaulins, cases, sailing clothes and shelters.
  • protective textiles such as e.g. clothing, canvasses, tents, tarpaulins, cases, sailing clothes and shelters.
  • the present invention relates more in particular to fabrics comprising steel cords or filaments or other cutting proof yarns.
  • the present invention further relates to the use of such a fabric to provide cut- resistance to protective textiles such as e.g. covers, clothing, canvasses, tents or shelters. It further relates to canvasses, composites and clothing, comprising such fabric.
  • canvas reinforcements comprising metal elements are also known from WO 98/55682. This document teaches that several metal elements, separated from each other and being embedded in a polymer strip, may be adhered to the inner side of canvasses to provide reinforcement. In order to prevent thefts, recently researches have been done to obtain cut resistant materials and constructions. This has already a lot of applications, especially in thermoharding materials. There are also known types of reinforcements for thermoplastic materials as e.g. a knitted "loop" fabric based on a knitted metal loop reinforcement. Also a woven tarpaulin reinforcement is already known comprising woven and knitted steel constructions. These last constructions have as major difficulty, i.e. the stiffness and the weight.
  • the first "loop" knit construction has as major difficulty when it is used as "anti- hooligan” fabric in seats of trains, trams, busses, it may, upon damage pierce and stick through the fabric. So even if it helps a lot to improve cut resistance in the fabric, the seat can no more be used as the metal will pinch through the skin of the user as well.
  • the woven fabrics, as the knitted as well have to be too heavy and too stiff in order to give enough cut resistance.
  • US Pat. No. 5,883,018 - Bourgois et al. discloses steel cords which are woven or knitted and have a warp and a filling under 90°.
  • WO 98/55682 of Van de Walle et al. also discloses a woven fabric with warp and weft as basic reinforcement under 90°.
  • WO 01/86046 of Leman et al. also discloses warp and weft elements connected to each other by weaving.
  • WO 98/45516 also discloses a fabric under 90° with metal strands.
  • a fabric comprises at least two layers and/or directions of individual elements, which might be laid upon each woven, stitched interlink. These fabrics might contain a warp and/or a weft.
  • the difference between multi-layered fabric and multi-axial directions is only in the fact that the individual elements with multi-axial directions are woven, stitched or knitted together lengthwise while for a multi-layered fabric they are kept together by chemical or mechanical, such as fusion means or by stitching or knitting or a combination thereof.
  • bias implies a direction diagonally across a piece of fabric at preferably 45 degrees to the warp and fill.
  • degrees to the warp and fill may differ from 45, in a range of from 1 to 89 degrees, for example 10, 20, 30, 40, 50, 60, 70 or 80 degrees.
  • Non-woven implies material obtained by assembling fibers with other chemical, mechanical, thermal or physical processes than weaving or knitting.
  • Knitting means implies a method for forming a fabric or textile surface produced by interlacing stitches (loops).
  • the warp comprises different warp elements, laying in a same direction, the so-called warp direction.
  • the weft comprises different weft elements, laying in a same direction, the so-called weft direction.
  • Each warp and weft element follows a certain path through the fabric, being respectively a warp path or a weft path.
  • at least one warp element or one weft element, or both comprise two or more elongated steel elements, which are in contact relationship with each other.
  • an individual element implies a warp element, preferably a yarn.
  • a warp element is to be understood as one or more individual elements such as e.g. yarns, filaments, bundles of fibers, wires or cords, which follow the same path through the fabric in warp direction.
  • all individual elements of a warp element cross the weft elements of the fabric in an identical way.
  • Weft element is to be understood as one or more individual elements such as e.g. yarns, filaments, bundles of fibers, wires or cords, which follow the same path through the fabric in weft direction.
  • all individual elements of a weft element cross the warp elements of the fabric in an identical way.
  • the innovation consists in the fact to have a textile construction which gives a maximum cutting resistance. Care needs to be taken so that the reinforcement yarns do not take the cutting loads as individual ends, but that the first warp or weft or other end will receive help in load bearing by a second, if needed a third end and so on before being destructed.
  • the textile construction will thereto preferably not be interwoven or interconnected by the reinforcement yarns by themselves, but being connected by other means as relatively weak textiles under shape of stitches, ends, non-wovens, chemicals or all kinds of combinations. These chemicals can be provided also as a matrix or a part of the matrix as well.
  • reinforcement yarns can be used, which can be whatever natural, synthetical or natural yarns including herein steel, glass, LCP, PEW, aramid, PA's, PET's, PP's, PE's and so on with a dtex of 200 and more and a tensile strength of more than 2 grams per dtex and a connection textile of whatever nature with a tensile strength preferably but not necessarily lower than 5 grams per dtex.
