Definitions

  • the invention relates to a warp knitted fabric which has differently structured areas both in the weft direction and in the warp direction, as well as to a warp knitting machine and to a method for producing such a knitted fabric according to the preamble of claim 1 or 8 or 14 .
  • a warp knitted fabric of this type which has a fabric base in tricot and a pattern by pile threads.
  • the warp knitting machine used to produce it has at least one, preferably two jacquard laying bars, which, in conjunction with a longitudinally displaceable pile board bar, ensures that the pile threads either form pile loops or are flatly integrated into the basic fabric.
  • a warp-knitted fabric is known from the LIBA brochure "ESJ-Electronic Sectional Jacquard", in which a fabric base in a tricot layer interacts with a pattern-forming fabric layer. This drape is through generated two laying bars, the needle pitch is twice as large as the knitting needle pitch, so that their laying needles are alternately assigned to the knitting needle lanes.
  • the patterning is carried out by the fact that one of the bars is jacquard-controlled and in this way the cloth is either displaced by a needle pitch or shortened to put on the jersey by needle displacement.
  • the first alternative leads to an openwork pattern, which is undesirable for many fabrics, while the second alternative has a thread consumption which is so reduced compared to the laying of the fabric that considerable differences in tension arise in the goods.
  • a warp knitted fabric with a plastic pattern can be achieved.
  • a reason is created here with a first laying rail, which works with full thread retraction.
  • the pattern formation serves two further laying rails, which work empty with a fillet feeder 1 full 1 and are supplied by a common warp beam.
  • they carry out underlays of different sizes, for example a tricot layer and a satin layer, these layers being changed so that each of these laying rails carries out the same number of different layers within a repeat.
  • the invention has for its object to provide a warp knitted fabric in both the weft direction and in the warp direction, the surface structure of which is determined partly by cloth layers and partly by other layers and whose pattern-forming threads are not exposed to inadmissible tensions even when they are from a common one Warp beam can be pulled off. Furthermore, the task is to specify a warp knitting machine and a method for producing this warp knitted fabric.
  • this object is achieved by the features of claim 1.
  • the sequence of different layers from the fringe, tricot, cloth, satin and velvet group allows a variety of surface structures to be created that differ from that of the cloth layer and also offer additional variation options due to their change. Because the selection is made in such a way that the average length of the underlay in predetermined repeats is approximately equal to the underlay length when the fabric is laid, in the areas thus formed and in the areas in which a fabric is laid, the same thread consumption results on average despite different layers . Insofar as different thread tensions result from the different layings, they balance each other out within a repeat.
  • the pattern can be formed by more than two different surface structures, because different combinations can be formed from said group of layers.
  • Preferred embodiments result from claims 3 to 5, which enable different patterns while maintaining the underlay average length.
  • Claim 6 describes a further embodiment of the surface structure. If the pattern thread system consists of two sub-systems, the threads of which are laid differently, crossovers result that are clearly distinguishable from the fabric. As a result of the cross-hairs, there is no one-sided warping of the warp knitted fabric in the pattern areas.
  • the basic thread system according to claim 7 is processed in tricot laying with particular advantage.
  • the object is achieved by the features of claim 8.
  • two pattern-forming Jacquard-Le-racks it is possible in a particularly simple manner, taking into account the demands made (patterning in the weft and in the warp direction; common warp beam for the pattern thread system; avoiding excessive tension in the warp knitted fabric) to produce patterned warp knitted fabrics.
  • the jacquard laying bars each experience a basic offset that repeats in each repeat, which determines a surface structure of the goods.
  • the two jacquard laying bars can also be used to produce crossing thread layers of the pattern-forming threads, as is often preferred.
  • the laying needles of one jacquard laying bar can be displaced in the opposite direction to the laying needles of the other jacquard laying bar. This makes it possible, under otherwise identical conditions, to carry out the greatest possible number of different layings with jacquard needles which can only be displaced on one side and which have a higher working accuracy than layers which can be displaced on both sides. A symmetrical control of the laying needles is also possible.
  • the object is achieved by the features of claim 14.
  • the process steps lead to the desired warp knitted fabric.
  • a warp knitting machine 1 has a knitting needle bar 2 with knitting needles 3, which cooperate with sliding needles 4, and inclusion knock-off boards 5.
  • the laying bars are displaced in the longitudinal direction in a conventional manner by bar control devices 6, 7 and 8 according to a predetermined pattern.
  • Mirror discs, sample chains or the like are used as control devices.
  • the laying needles 9 are firmly attached to the laying bar L1. They have the same pitch as the knitting needles 3.
  • the pitch of the laying needles 10 and 11 of the laying bars L3 and L2 is twice as large as the knitting needle pitch.
  • the laying needles 10 and 11 are at a gap (FIG. 2) and can be displaced in the opposite direction by one knitting needle pitch in each case by displacement boards 13 and 14 (cf. arrows 13 'and 14' in FIG. 2).
  • the displacement boards are actuated via harness cords 15 and 16 and are triggered by corresponding jacquard control devices 17 and 18 in accordance with a predefined displacement program.
  • a common jacquard control device 117 can also be used, which has individual control elements 118, for example electromagnets, which each have two harness cords 115, 116 or the like. act, which lead to displacement boards of various jacquard laying bars.
  • the threads 19 of the basic thread system fed to the knitting point via the laying needles 9 are of a warp beam 20 withdrawn, the threads 21 and 22 of the two subsystems of the pattern thread system fed via the laying needles 10 and 11 are drawn off from a common warp beam 23.
  • the warp knitting machine of FIG. 1 uses the threads 19 to create a coherent fabric base, which in particular is laid continuously as a jersey.
  • the threads 21 and 22 can be laid in base areas B as a cloth, as shown in FIG. 4.
  • M1, M2 and M3 modified lay-up combinations are used, but which have the same thread consumption as the cloth lay-up in each repeat.
  • jersey there is an interesting patterned charmeuse knitwear.
  • the structure of the knitted fabric and its production are explained in more detail in connection with the layout images of FIGS. 5 to 8.
  • the base region B is generated according to FIG. 6.
  • M1 corresponds to FIG. 5, M2 to FIG. 7 and M3 to FIG. 8.
  • FIG. 5 which corresponds to the pattern area M1 shows that in a repeat R comprising eight working cycles, the jacquard laying bar L3 carries out a basic offset, which has the following course: jersey-cloth-jersey-jersey-cloth-satin-satin cloth.
  • the Jacquard laying bar L2 sets in the basic offset: satin-cloth-cloth-satin-cloth-leotard-leotard cloth. There are therefore two tricot layers, four cloth layers and two satin layers in each repeat. The average backing is therefore just as large as that of the cloth.
  • the laying pattern L3 results in the following laying: Cloth-cloth-fringe-cloth-velvet-velvet cloth.
  • the laying is: velvet-cloth-cloth-velvet-cloth-fringe-fringe.
  • the average backing is the same as that for the backing.
  • the basic offset contains jersey and satin layers, it is very easy to change not only to cloth layers, but also to fringe and velvet layers.
  • the additional use of cloth layers for the basic offset enables a higher number of pattern modifications. It also makes the transition from fringe to easier Velvet and vice versa.
  • the layings are made in such a way that all stitches of the basic fabric are covered with stitches of the pattern thread system in the middle of the pattern areas. It goes without saying that, in the case of a different basic offset, other combinations or sequences of layings are also possible.
  • FIGS. 9 to 11 Another exemplary embodiment is illustrated in FIGS. 9 to 11.
  • the jacquard laying bars L2 and L3 are designed so that their laying needles can be pushed ver in the same direction according to the arrows 13 'and 14'.
  • the laying needles are arranged one behind the other in the non-displaced position.
  • the two layings each begin in the same needle alley; a needle remains in between.
  • the threads 21, 22 do not form stitches common to all stitches of the basic fabric. However, this is not necessary because the goods reason is self-contained.
  • the basic offset of FIG. 9 provides the following laying for the jacquard laying bar L2: satin-cloth-cloth-satin-cloth-leotard-leotard cloth.
  • the L3 jacquard laying bar places one after the other: jersey-cloth-cloth-jersey-cloth-satin-satin cloth. This results in a first pattern area M1.
  • FIG. 10 shows the base area characterized by a uniform cloth pattern.
  • the laying needles of one or the other jacquard laying bar are displaced in each case.
  • FIG. 11 shows a second pattern area which corresponds to FIG. 8 and can therefore be referred to as pattern area M3.
  • pattern area M3 By selectively actuating the laying needles of a jacquard laying bar, repetition in each repeat R becomes Pattern is generated in which the average length of the underlay for each repeat is approximately equal to the underlay length for the fabric layer.
  • the basic offset according to FIG. 12 provides two identical partial reports R1 and R2.
  • the base area B is not illustrated. It arises analogously to FIG. 6 by lengthening the tricot layer and shortening the satin layer. This means that the laying needles of the jacquard laying bars L2 and L3 are displaced in opposite directions in the first and last step of each partial repeat R1 or R2.
  • a pattern area M2 is illustrated in FIG. 13. Here it is shown how, by differently displacing the jacquard-laying needles in the two repeats R1 and R2, an eight-line repeat is created in which the jacquard-laying bar L2 velvet-cloth-tricot-satin-satin-tricot-fringe-cloth and the jacquard- Laying bar L3 fringe cloth satin leotard leotard satin cloth sets.
  • a third displacement program for generating a pattern area M3 is also possible, which corresponds to FIG. 8. This means that two tricot layers and two satin layers alternate with each other. For this it is necessary in each sub-report in the third and on the fourth line, to push the laying needles of the Jacquard laying bars L2 and L3 in opposite directions.
