Definitions

  • the invention relates to a knitted pile loop knitted fabric as well as a method and a machine for its manufacture, which are used in the production of textiles with a one- and two-sided pile loop surface.
  • a pile loop knitted fabric with a one-sided and two-sided liropole loop pile which consists of a fabric base or a basic fabric, the weft stitches of binding warp threads placed in fringe weave and a weft thread system, which are bound between the needle and sinker stitches of the fringe via four wales. and is formed by a back and front pile thread, each of which is tied between the needle and sinker stitch of the fringe between two adjacent sticks (Vliesstoffe, Verlagtechnika, 1980).
  • a disadvantage of the Liropol knitted fabric is a separation of the fabric base, caused by the fringe binding, a limited structural range of the knitted fabric, insufficient strength of the loop pile when pulling the front pile threads and insufficient hygienic properties of the knitted fabric due to the inevitable use of continuous threads as knitting threads.
  • the knitting needles successively pass from a rear end position to a zone for laying back pile threads, a zone for pressing the back pile threads and a weft system, a zone for laying a weft system, and a zone for the laying of the front pile threads and reach a front end position for the laying of knitting threads.
  • the front pile threads are not knitted, but are tied with the knit threads through the plate and needle loops of the fringe, with the laying of the one weft thread system and the rear pile threads over the knitting needles and the withdrawal under the knitting needles using a special printing plate.
  • the machine used to produce Liropol knitted fabrics with one and two-sided loop pile consists of knitting needles with a slot that run perpendicular to the plane of the front and rear pile boards. Slider needles are featured between the knitting needles see. Special pressure plates and perforated needles for the rear loop surface are arranged behind the rear pole plates. In front of the front pile sinkers, perforated needles for the front pile surface and perforated needles for the knitting threads are arranged. In the Liropol machine, needles with a slit have to be used, which requires a high tension of the knitting threads, which increases the thread breakage frequency and the errors in the knitting, unless one uses solid and elastic continuous threads as knitting threads.
  • the state of the art also includes a loop-loop-knitted pile loop knitted fabric in which the structure of the Liropol knitted fabric is perfected.
  • the normally open front pile loops are formed by the front pile threads of the Liropol knitted fabric and are tied at least in the predominant part of those rows of stitches in which they are placed level with the knit yarns between the needle and sinker stitches, with the open loops formed in all stitches on the right side of the goods are pulled through (DD-B-134789).
  • the front pile threads are presented to the crochet hooks in every second row of stitches equally to the binding warp threads and thus clamped on the shaft of each needle.
  • the clamping is maintained, an open loop made of pile thread material being formed from a thread reserve, which is achieved when the stitch formed by the knitting needles is pressed.
  • only the mesh strength of half of the pile rows can be improved.
  • the machine for the manufacture of knitted-loop pile loops differs from the Liropol machine in that there are movable additional pile boards at the locations between the needles in front of the front pile boards. They can be raised and lowered to supply the thread reserve for forming the loop from pile thread material.
  • the object on which the invention is based is to provide a pile loop knitted fabric with improved properties in terms of stitch strength and the strength when pulling front pile threads, in which natural fiber yarns can be used as knit yarns in a wide range of stitch structure, a method for producing such a pile loop knit fabric that has a firm Binding of the front pile threads in each row of stitches with the fringe stitches is guaranteed and the production of varied stitch structures is permitted, as well as creating a machine for producing the pile loop knit with a varied structure, with which the thread tension and the frequency of thread breakage can be reduced with a simple construction.
  • This task is based on a pile loop knitted fabric, which consists of a fabric base or a basic product, the or of the wales of the binding warp threads laid in a closed fringe and a weft thread system, which are tied between the sinker and needle loops of the fringe, and from the front and the rear pile threads are formed, the rear pile threads each being bound between two adjacent wales between the needle and sinker loops of the fringe, according to the invention solved in that the front pile threads are knitted as plating loops of the fringe in two successive courses of two adjacent wales and one or several weft thread systems placed in the same or opposite direction under one or more wales and bound between the sinker and needle stitches of the fringe and run between the sinker and needle loops of the front plating pole loops.
  • the front pile threads are achieved according to the invention placed and knitted on two adjacent needles in two successive rows of stitches simultaneously with the laying of the knitting threads, whereby two adjacent wales are formed with open or closed stitches and a front interposed pole face, one or more weft thread systems are placed in the same or opposite direction, under the knitting needles stay in one or more rows of stitches over one or more wales, and the back pile threads are placed in front of two wales and stay under the knitting needle.
  • the knitting needles are latch needles. At least two weft hole needle systems are arranged between the rear and front pole boards. On the side of the front pile boards there are perforated needles for the front pile threads and the perforated needles for the chains warp threads arranged symmetrically below and above the plane of the knitting needle.
  • the knitting needle can have a tip under which a sliding surface is formed.
  • a pile loop knitted fabric with a loop-proof base and pile loop resistance when pulling the pile threads in a diverse structure can be produced by combining the two weft thread systems.
  • the hygienic properties of the knitted fabric are very good due to the possible use of knitting yarns. Due to the reduced thread break frequency of the knitting threads due to the reduced dynamic stress during laying, increased productivity can be achieved.
  • the machine for producing a pile loop fabric with a drawn loop pile has knitting needles 1 which are arranged symmetrically perpendicular to the plane extend front and rear pole boards 7 and 8 which are immobile. In between, one or more weft needle systems 4 and 5 are arranged, into which the weft threads 10 and 11 are drawn.
  • the needles 3 and 13, in which the knitting threads 9 and the pile threads 14 are drawn in, are arranged in front of the knitting needles 1.
  • the perforated needles 6, in which the pile threads 12 are drawn in, are arranged behind the rear pile boards 8.
  • the knitting needles 1 pass through a slot in the support rail 2, which is arranged behind the rear pole plates 8.
  • the knitting needle 1 (FIG. 6) consists of a shaft with a tapered part 19, in the front end of which a tongue 18 is held in an extension via a joint 17 and, after the extension, a socket 21 which is in a hook 20 with a tip 15 ends, is formed, under which a sliding surface 16 is provided.
  • the pile loop knitted fabric is produced as follows:
  • the knitting needles 1 move back and forth and run during the movement to the front dead center according to FIG from the needles 4 and 5 weft systems 10 and 11.
  • the back pile threads 12 and the weft systems 10 and 11 are placed by a horizontal movement to the left and right and a vertical movement of the needles down and up.
  • the horizontal and vertical movement of the two weft hole needle systems is independent of one another and can be designed as desired for a given row of stitches depending on the technological task.
  • the horizontal movement of the perforated needle 6 realizes the laying of the rear pile threads over one or two needle divisions.
  • the knitted fabric does not have a left-hand pile surface over a needle pitch.
  • the knitted fabric has a left-hand pole face via two needle divisions by means of the rear pole plates 8.
  • the perforated needles 3 place the warp knitting threads 9 in fringed weave in the knitting needles.
  • the perforated needles 13 place the front pile threads 14 in the knitting needle in a jersey weave.
  • the essence of the laying consists in the laying of the threads in the stubs 21 of the knitting needles 1.
  • the perforated needles 3 perform two movements, namely the laying of a needle pitch to the left or to the right and a shaking movement down and up .
  • Each perforated needle 12 places the pile threads 14 of two adjacent knitting needles in two successive rows and forms by means of front pole plates 7 a right pole face.
  • a weft thread system 10 which is laid over four wales for one stitch row and formed by a weft thread system 11, which is tied through the sinker and needle stitch of the fringe and laid over four wales for the next course.
  • the front pile threads 14 are knitted as plating loops of the fringe loops through the warp knitting threads 9 in two consecutive courses of two adjacent wales.
  • the rear pile threads 12, which are laid through the perforated needles 6, which form the left pile surface, are not shown in the figure.
  • the bottom of the knitted fabric is formed by wales, which are knitted by the warp knitting threads 9, which are bound by the sinker and needle stitch of the fringe with weft thread system 10 and 11, which are tied in opposite directions via two wales for each stitch row.
  • the front pile threads 14 and the rear pile threads 12 in the knitted fabric are analogous to the knitted fabric of FIG. 7.
