Definitions

  • the invention relates to a voluminous, spring-elastic mat structure consisting of a extremely coarse warp-knitted fabrics with incorporated weft elements that are flat Load has a very high resilience and preferably as a seat and Lying surface is used.
  • Elastic, warp-knitted mat constructions usually consist of Spacer fabrics with two goods, which are kept at a distance by monofilament threads are.
  • a spacer fabric is known for example from DE-AS 28 57 400, the is produced on a warp knitting machine with two needle bars. Every knitting needle contour serves to manufacture a basic product. Monofilament threads that go from one to the other The two hold the knitting needle shape and are integrated into the stitches there Basic goods at a predetermined distance and offer a certain pressure resistance and Elasticity.
  • the well-known spacer fabrics come up open Limits. Especially with larger distances between the two outer sides and with stronger ones The spacer threads are compressed in an impermissible manner under pressure.
  • Mat structures made from a warp knitted fabric with incorporated weft elements well known, for example the use as a flexible heat exchanger element (DE 35 12 874), in the hoses for the transport of the heat transfer medium as a binding element Weft along and across are integrated into a warp knit. Due to the fixed positive Integrating the hoses into the warp knitted fabric becomes their geometrical arrangement permanently secured. The warp knit structure absorbs tensile forces and the surface stability is further increased by incorporating ropes and rods.
  • voluminous and dimensionally stable filter material is sliver-like Fiber material in the form of card tapes as a front and rear weft in Combination with sliver-like standing weft threads together with meandering ones Tubes integrated in a right / right mesh structure.
  • This filter material serves at the same time as a heat exchanger for hot air and hot gas filtration.
  • Mat structures described are preferably non-textile weft elements for the corresponding fields of application as relatively loose voluminous structures, so that high pressure loads are insufficient even over a long period of time have it compensated.
  • the present invention is therefore based on the object of a mat structure to create the type described above, which is highly elastic due to its structure Deformation enables a high heat retention or thermal insulation as well as a ensures very good moisture behavior and the provision of different Dimensions are easy to maintain for a wide range of applications.
  • the voluminous, spring-elastic mat structure shown in the drawing consists of a right / right warp knitted fabric of extremely coarse structure that on a Raschel machine can be manufactured with appropriately dimensioned knitting tools.
  • the distance of the both sides of the basic fabric is approx. 12 mm and the distance a is Wales approx. 40 mm.
  • the knit side has continuous weft elements 1 which are close together.
  • These weft elements 1 consist of rope-like, loose fiber structures 5 with a Diameter of 20 mm, for example.
  • the diameter of the weft elements 1 corresponds preferably at least 10 times the value of the basic thread.
  • the fiber structures 5 consist of 100% cotton fibers.
  • Natural fibers be made from synthetic fibers or mixtures thereof. Encased are the rope-like fiber structures 5 with a tubular, net-like Mesh tube 3, which consists of at least four spirally extending in the longitudinal direction Mesh 4 is formed. The sheathing of the mesh tube 3 causes the loose fiber structures 5 are biased radially. An additional preload on the Shot elements 1 is achieved in that the compressed, loose fiber structures 5 in Distance a are tied radially in the wales 2 of the warp knit.
