Definitions

  • This invention relates to erosion preventing structural elements which consist of stitched webs of fleeces made of coarse, crimped polyamide fibres.
  • fleeces are resistant to rotting and decay.
  • Fleece binders are applied to fix the points of intersection and contact between the fibres and the fleeces may also be bonded by means of thermoplastic adhesive fibres.
  • These bulky fleece webs are laid down wherever it is required to prevent erosion by water and/or wind. They are fixed in position e.g. by weighing them down with stones or covering them with sand, gravel or asphalt, concrete and/or soil or by nailing them down with stakes, etc.. These webs of fleece may also be used for fixing turf and for arresting the movement of dunes and for reinforcing dams or dykes.
  • an erosion preventing structural element in the form of a stitched web of fleece made of coarse synthetic fibres, which comprises a. crimped polyamide fibres with dtex to 250, preferably dtex 30 to 140, and staple lengths 20 to 150 mm, preferably 50 to 100 mm, stitched with 60 to 180 stitches per cm, preferably 80-120 stitches per cm,
  • a mesh fabric of synthetic yarns or tapes comprising at least two warp yarns and two weft yarns per cm stitched into the web in the lower third thereof and c. at least by weight and preferably to 45% by weight based on the weight of the fleeceof a waterproof binder based on polyacrylic acid esters, this web of fleece having a thickness of 4 to 10 mm and a weight per square metre of between 500 and 2000 g, preferably between 500 and 1700 g.
  • the erosion preventing structural element according to the invention is produced by a process which comprises laying crimped polyamide staple fibres of dtex 5 to 250 to form a fleece, the formed fleece and a mesh being stitched together, the stitched fleece being impregnated with a waterproof binder based on polyacrylate and subjecting the impregnated fleece to a heat treatment at temperatures of between 100 and 150C.
  • the waterproof binders based on polyacrylates are, for example, binders produced from self cross-linking acrylic acid esters, preferably butyl acrylate. They are preferably applied in the form of aqueous dispersions. Fillers such as barium sulphate, kaolin or chalk may be added to the aqueous dispersions to increase the weight of the element so that the web will sink more quickly when laid under water. Sinking of the web may also advantageously be speeded up by the addition of wetting agents (tensides) in quantities of 2 to 20% by weight, preferably 4 to 10% by weight, based on the finished web of fleece.
  • the wetting agents used may be alkyl-(aryl) sulphonic acids or sulphonates or also nonionogenic compounds.
  • the mesh fabric is advantageously produced from multifilamentary polyester yarns of dtex 900 to 1200 woven to produce a fabric having 4 warp yarns and 4 weft yarns per cm the weight per square metre of the mesh fabric should be between 80 and 160 g.
  • the fabric is arranged in the lower third of the web of fleece so that loops of fibres projecting from the undersurface of the fleece will provide a firm hold on the ground which is to be protected.
  • the layers of fleece on both sides of the mesh fabric are protected against mechanical damage, for example from gravel or broken stone.
  • the webs of fleece may be produced by known methods in any fleece forming installations, preferably by the aerodynamic principle.
  • the binder is introduced into the web of stitched fleece in the form of an aqueous dispersion, for example by slop padding or spraying, and is then condensed, usually at elevated temperatures.
  • the web of fleece may be drawn through a pair of heated rollers (Calender rollers).
  • the process for producing erosion preventing structural elements in the form of webs and stitched fleeces is characterised in that crimped polyamide staple fibres of dtex 5 to 250 are laid to form a fleece by an aerodynamic process and/or using a carding machine, and the fleece is then stitched to a mesh fabric and the stitched fleece is impregnated with a waterproof polyacrylate binder and the impregnated fleece is subjected to a heat treatment at temperatures of between l00 to 150C.
  • the mats produced by the process indicated above are treated with a wetting agent (tenside), preferably 2 to 20% by weight.
  • sinking may be facilitated by applying a filler of high specific gravity (e.g. barium sulphate, kaolin or chalk) together with a binder.
  • EXAMPLE 2 Polyamide-6 staple fibres (130 dtex, staple length 60 mm) are worked up in an aerodynamic fleece laying apparatus to form a web of fleece weighing 1000 g per m The fleece is then treated as described in Example 1 and after condensation of the polybutyl acrylate it is impregnated with a 70% by weight aqueous solution of a wetting agent mixture consisting of 70% by weight of alkyl (C to C sulphonate and 30% by weight of nonylphenolpolyglycol ether (7 mols of ethylene oxide), 120 g of this solution being introduced per m of fleece web.
  • a wetting agent mixture consisting of 70% by weight of alkyl (C to C sulphonate and 30% by weight of nonylphenolpolyglycol ether (7 mols of ethylene oxide), 120 g of this solution being introduced per m of fleece web.
  • the finished web of fleece contains 6% by weight of wetting agent and has a final weight of about 1500 g/m and a thickness of 9
  • the figure illustrates an example of an erosion preventing structural element according to the invention in the form of a web of fleece (in cross-section) of polyamide-6 fibres.
  • Fleece 1 is composed of polyamide-6 fibers 2 (diameter 0.10 mm, staple length 60 mm), some of the loops of fibers being stitched through the mesh fabric consisting of warp yarns 3 and weft yarns 4 mechanical strengthening of the web was carried out in a stitching apparatus by applying 90 stitches per cm with 28 gauge needles.
  • the polyacrylate binder content is 30% by weight.
  • the mesh fabric has 4 warp threads and 4 weft threads of multifilament polyester fibres of 1100 dtex and has a weight per m of 110 g.
  • the finished web of fleece has a thickness of 8 mm and a weight per m of 1600 g.
  • An erosion preventing structural element in the form of a stitched web of fleece of coarse, crimped fibres consisting of a web of fleece produced from a. crimped polyamide fibres of dtex 5 to 250 and staple length 20 to 150 mm stitched with 60 to 180 stitches per cm b. a mesh fabric of synthetic endless yarns stitched into the fleece, the fabric having at least 2 warp yarns and 2 weft yarns per cm and being arranged in the lower third of the web of fleece, and
  • a waterproof binder based on polyacrylic acid ester of at least 15% by weight this web of fleece having a thickness of 4 to 10 mm and a weight per m of between 500 and 2000 g.
  • a process for the production of erosion preventing structural elements in the form of webs of stitched fleeces of synthetic fibres which comprises laying crimped polyamide staple fibres of dtex 5 to 250 to form a fleece, stitching together the formed fleece and a mesh fabric, impregnating the resultant combination with a waterproof binder based on polyacrylate and subjecting the impregnated fleece to a heat treatment at temperatures of between 100 and C.
  • aqueous dispersion of binder contains a filler having a high specific gravity.
  • the erosion preventing structural element according to claim 1 which contains 2 to 20% by weight of a wetting agent.
  • said mesh fabric consists of 4 warp yarns and 4 weft yarns of dtex 900 to 1200 per cm and has a weight per m between 100 and 150 g.
