Definitions

  • the present invention relates to warp knitted fabric especially for shirts, underclothing and similar items.
  • Shirts and underclothing manufactured of synthetic fiber, such as polyamide fabric have two principal disadvantages, viz. they are unpleasant to wear by reason of the poor ability of the material to absorb perspiration, and they rapidly become dirty as a result of the strong electrostatic charge in the material which attracts dirt and particles of dust.
  • An object of the present invention is to eliminate the above-mentioned disadvantages, and the warp knitted fabric produced by the invention is principally characterized by its consisting of fibers of high moisture absorption capacity in a three-layer composition, such that the fiber layer of high moisture absorption capacity lies completely between two synthetic fiber layers.
  • the moisture absorption capacity of the warp knitted fabric made in accordance with the invention is at least 5.86.2%, that is to say 50% greater than the moisture absorption capacity of a pure polyamide fabric, which is 3.64.0% as a maximum. This results from the high moisture absorption capacity of 13.5% for silk against, for example, 8% for pure cotton.
  • the consequence hereof is that also the moisture transmission ability is considerably improved by the material produced according to the invention as compared to conventional nylon, perlon and the like fabrics.
  • the fabric according to the invention gives the number 23. This shows that the moisture transmission capacity, i.e., the respiration ability of the fabric according to the invention is roughly 2.5 times greater than goods made of ordinary nylon, perlon and other known synthetic fibers.
  • the special three-layer structure is suitably achieved by introducing in a 3-bar warp knitting machine the moisture-absorbing yarn by means of blind-laying, without making stitches by the back guide bar in normal warp knitted structures for shirt and underclothing fabrics.
  • the moisture absorbing yarn is an inlay or filler yarn without any binding purpose and is protected on either side by a layer of synthetic fiber.
  • the rayon yarn lies as an intermediate layer in the three-layered material, and in no way affects shrinkage. Neither can there occur the typical cutting-01f of rayon threads, which becomes apparent in known combinations.
  • Both the face and the back of the fabric accordingly consist of hard-wearing and nearly shrinkfree polyamide fiber, and thus the material can be made up on both the face and the back. Wear tests (abrasion tests) have shown that the tear strength of this type of fabric is just as good as that of pure polyamide fabrics.
  • Warp knit fabric in accordance with the invention can be manufactured on a usual bearded needle warp knitting machine with 3 (or more) guide bars, by the use of for example, 40 den rayon yarn in the back guide bar, and 40 den polyamide yarn in the middle and front guide bar characterized by the following link pattern for the guide bars, as illustrated in the attached drawing, wherein:
  • FIGS. 1-6 diagrammatically show various patterns for three layer structures.
  • a method of knitting a three-layer warp fabric on a warp knitting machine having a bed of needles and at least three guide bars, a front, middle, and back guide bars, said front and middle bars being threaded with synthetic yarns of lower-moisture absorption capacity than the back bar which is threaded with yarns of high moisture absorption capacity comprising: forming a top layer and a bottom layer of knitted stitches with said front and middle guide bars having said yarns of lower moisture absorption capacity, and laying in said yarn of higher moisture absorption capacity over 2-3 needles with the back guide bar between said knitted stitches of said top and bottom layers of said synthetic yarns to form a middle layer without stitches.
