Definitions

  • the invention relates to a bi-elastic warp knitted fabric with a balanced behavior of the elastic forces in the longitudinal and transverse directions.
  • warp knitting in the warp knitting side-by-side runs in the longitudinal direction are looped together. This is done on warp knitting machines, Raschel machines and crochet gallon machines.
  • Some of the warp threads (approx. 5 to 50% by weight) can be elastane yarns which give the knitted fabric elastic properties.
  • Highly elastic articles such as corsetry and swimsuits can be made from such elastic knitwear. (Bela von Falkai, synthetic fibers, Verlag Chemie, Weinheid, Deerfield Beach, Florida; Base., 1981, pp. 189 to 190 and 348 to 351).
  • a disadvantage of the elastic warp knitted fabrics produced with the help of warp threads from elastane yarns is that a balanced behavior of the elastic forces of the knitted fabric in the transverse and longitudinal directions cannot be achieved. This is independent of the ratio in which the elastane yarns to the other yarns, hereinafter referred to as hard fiber yarns, are used.
  • the object of the invention is therefore a bi-elastic warp knitted fabric, characterized by thread loops of elastane yarn horizontally integrated into the loops of the basic warp knit as a weft thread. These thread loops are preferably suspended in one another.
  • the basic warp knitted fabric preferably consists exclusively of hard fiber yarns.
  • the bi-elastic warp knitted fabric according to the invention offers a further advantage in terms of production, since, compared to conventional elastic warp knitted fabrics, the parallel, longitudinally running elastane yarns are eliminated, so that the elaborate and costly warping of the elastane yarns into elastane yarn part warp beams is eliminated and the elastane yarns for processing as weft yarn, which is formed into thread loops, preferably into interlocking thread loops, can be withdrawn from simple bobbins.
  • Elastane yarns are preferably used which have an extensibility of at least 250%, preferably 450 to 650%, in particular those with titers of 10 to 960 dtex, preferably 33 to 480 dtex.
  • Bare elastane filament yarns but also wrapped or wound elastane filament yarns can be used. Bare spandex filament yarns are preferred.
  • the knitted fabric according to the invention is produced in that the elastane yarn drawn off the bobbin is guided as a weft thread during the stitch formation process in the catching or laying position under the needle tips, whereby thread loops are formed when knocking off.
  • This can be done manually on all warp knitting machines, such as warp knitting machines, Raschel machines and crochet gallon machines, or mechanically after appropriate conversion.
  • the new technology can be used for all types of warp knitting.
  • weft threads in warp knitted fabrics is already known with hard fiber yarns and elastane yarns, but has so far been carried out in a fundamentally different way and for a different purpose.
  • the weft threads made of hard fiber yarns do not take part in the stitch formation and are intended to give the knitted fabric a stability corresponding to the woven fabric. For this reason, they are inserted smoothly between the needle stitch and the sinker stitch.
  • a product with 48 courses / cm and 25 wales / cm is obtained, which has a weight per unit area of 230 g / m 2 .
  • the elasticity in the longitudinal direction is 220%, the elasticity in the outward direction is 250%.
  • the percentage by weight of elastane is 50%.
