Definitions

  • a warp knitted pile fabric is formed on a single set of spring or bearded needles with two or more yarn guides by leaving some of the needles empty and using them for forming loops, but not stitches of the pile yarn.
  • the pile yarn crosses one or more wales of ground fabric stitches between loops and is bound to at least one of the crossed wales by being laid into the stitches of the same without itself forming any stitches.
  • This invention relates to a method of preparing a warp knitted fabric having pile or plush yarns which form loose loops.
  • the object of the invention is the provision of a warp knitted fabric having equally long loops of pile yarn on both faces, not limited to pile yarns of low bulk, yet having a basic stitch structure which need not be unusually heavy.
  • a pile fabric can be knitted on a warp knitting machine having a single needle bar, spring needles, and at least two yarn guides if loops of pile yarn are formed on empty knitting needles without the formation of stitches, and the pile yarn intersects one or more chain stitches of the base fabric between successive loops so as to be laid in the stitches and bound to the same without the formation of stitches in the pile yarn.
  • the stitches of the base fabric are thus entirely unaffected by the pile'yarn loops, and the pile yarn may be of any bulk desired within the limits set by the dimensions of the knitting needles which must engage the pile yarn.
  • the pile yarn loops may be rnade the same on both faces of the fabric, and the loops may be combined with any pattern of the base fabric.
  • FIG. 1 diagrammatically illustrates a fabric prepared by the method of the invention on a bearded needle machine having three guide bars;
  • FIG. 2 similarly shows a fabric prepared on a machine having four guide bars
  • FIGS. 3 and 4 respectively illustrate modifications of the fabrics of FIGS. 2 and 1.
  • the fabric pattern illustrated in FIG. 1 was produced by lapping movements of three guide bars as follows:
  • the fabric pattern illustrated in FIG. 2 was produced by four sets of yarns threaded in respective guide bars which performed the following lapping movements:
  • the base fabric consists of wales of plain stitches 14 connected by two sets 11, 12 of tricot stitches with opposite laps, whereas the pile loops are formed as described with reference to FIG. 1 by laid-in pile yarn 13 forming loops on otherwise empty needles.
  • Guide Bar IV 1-0/ 0l/ 10/ 0-1 Guide Bar III: 23/1-1/10/22 Guide Bar II: 1-0/2-2/2-3/1-1 Guide Bar I: 0-0/ 5-5/ 0-0/ 5-5 and repeat
  • the base fabric is formed by chain stitches 24 with laidin weft threads 21.
  • Two sets of pile yarns 22, 23 form loops about empty needles and are bound to the base fabric by opposite lapping movements of the associated guide bar II and III.
  • the fabric diagrammatically illustrated in FIG. 4 is produced on a single set of spring needles by means of three guide bars making lapping movements as follows:
  • the base fabric is formed by wales of plain stitches 43 connected by the yarn 41 of guide bar II in an Atlas pattern, and holds the loops of the pile yarn 42 which extend between the stitches of the basic fabric.
  • both ends of each pile loop are laid in and anchored in stitches of the ground fabric which are in different courses of the latter, and actually separated by at least one course of stitches of the ground fabric which is free from laidin pile yarn.
  • both ends of each loop may be in the same wale of the ground fabric or in diiferent wales.
  • the pattern of the base fabric may be chosen at will to suit specific requirements, and any desired base fabric may be provided with pile loops by the method of the invention.
  • a warp knitted pile fabric comprising:
  • a method of warp knitting a pile fabr c which com- 5 prises (a) knitting stitches of a base fabric from a first set of yarns on a first group of needles in a needle bed;
