Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a knitted standing knitted fabric comprising a warp-knitted base fabric having spaced pile yarns rising from the base fabric, and producing a knitted fabric so knitted, Bottom) The thread guide (guide finger) assigned to the rear needle bar to produce the base fabric structure, and the thread guide (guide finger) assigned to the front needle bar to produce the front (front) fabric fabric. ), A pile yarn guide (pile guide finger) for alternately supplying pile yarns to the rear and front needle bars, and a control device for controlling the yarn guide (guide finger).

[0002]

[Problems to be solved by conventional techniques and devices]

 In all known knitted napped knitted fabrics, the napped pile is relatively easily pulled out of the base fabric. This is, in particular, a pile yarn material of less than 200 dtex. With suitable post-treatment, the pull-out resistance can be increased to some extent, for example, by heat-setting the knitted fabric. However, this is not sufficient for many applications of knitted fabric with nap.

[0003] A special application is the napping of toys used to produce nappied animals and the like. In particular, infants play with nappied animals and put them in the mouth, so that the nappiles may dislodge from the underlying tissue and their synthetic filaments may reach the child's stomach. The stomach acid then pulls out the softener from the synthetic fibers, which solidifies and hardens to the same extent as glass. This can lead to gastrointestinal disorders.

[0004] For other end uses of nappi knitted fabrics as well, higher pull-out resistance of the nappiles is desirable to greatly improve the quality of the item.

An object of the present invention is to obtain a high pull-out resistance of the piles for the knitted knitted fabric as described above.

[0006]

[Means for Solving the Problems]

 According to the present invention, this problem is solved for a similar type of knitted fabric by knitting the pile yarn into the base fabric at least twice as loops between every two exit positions.

[0007] In this knitted fabric, all raised piles are obtained by weaving at least two loops. Extraction is almost impossible.

It is particularly advantageous for the pile yarn to be woven at least three times as loops in the base fabric between every two exit positions. This results in a particularly strong braid.

It is advisable to arrange the pile yarns as open or closed pillar stitches.

In a further embodiment, the pile yarn loops can be arranged as a staggered open or closed pillar stitch.

[0011] The base fabric advantageously comprises a double tricot or Charmeuse. This results in a resilient backing tissue.

[0012] Alternatively, it is also advantageous if the base fabric consists of pillar stitches and wefts which provide a strong base fabric.

[0013] The present invention further includes a double needle bar warp knitting machine as described above, the control device of which is such that the pile yarn between courses to the corresponding other needle bars is formed as a loop in the front base fabric. It is configured to be woven at least twice.

Since the pile yarns are subsequently transformed into the naps forming the nap pile by cutting, the pile yarns are subject to tension and the pull-out resistance of the nap pile performed is of particular importance. Has the property.

[0015] The control device is responsible for arranging the pile yarns, and is arranged such that the arrangement of both the pile yarns and the base fabric texture yarns is performed in a desired manner.

[0016]

[Embodiment of the invention]

 The present invention will now be described by way of preferred embodiments with reference to the drawings.

FIG. 1 shows a knitting area of a double needle bar warp knitting machine having a front (V) needle bar 1 and a rear (H) needle bar 2. The corresponding knitting needles (latch needles) 3, 4 and other knitting elements are merely schematically outlined in the knitting area. The six guide bars L1 to L6 are provided with thread guides (guide fingers) 5 for supplying six thread sheets to the needles 3 and 4 of the needle bars 1 and 2, respectively. The yarns 6 and 7 of the guide bars L1 and L2 form a front fabric structure 12, and the yarns 10 and 11 of the guide bars L5 and L6 form a back fabric structure 13. The pile yarns 8, 9 supplied by the guide bars L3, L4 are alternately arranged on the needle bar 1 and on the other needle bar 2, thus the tensioned intermediate of the pile yarns. An area 14 is generated. This area 14 is later cut, for example by a center-cut machine, so that the pile yarns are raised piles forming the desired raised pile on each side. The control device S controls the needle bars L1 to L6. It is configured to obtain the wrapping described below.

In the following figures of the wrapping, it is known that from a straight line to a straight line, the wrapping is shown alternately on the front (V) needle bar 1 and on the rear (H) needle bar 2. Is important.

FIG. 2 shows pile yarns 8, 9 which are knitted by guide bars L3, L4, which are here knitted as open pillar stitches. It is provided that between every two courses to the corresponding other needle bar, two pile yarn loops 18, 19 are braided into the base fabric structure, thereby providing that said pile yarns are firmly fixed. is important.

In the embodiment according to FIG. 3, the situation is similar, but the pile yarn here is knitted as a staggered open pillar stitch.

In the embodiment according to FIG. 4, even three loops 18, 19 and 20 are woven into the fabric structure between two successive courses 16, 17 and the pile yarns in the fabric structure Produces a stronger fixation.

In FIG. 5, the guide bars L3 and L4 are also pile yarns so that three loops 18, 19 and 20 are formed between successive courses on the corresponding other side of the base fabric structure. 8 and 9 are arranged, and the pile yarn is knitted in the base fabric structure. The main difference is that the repeat represented between both horizontal straight lines includes 20 knitting courses of the warp knitting machine, while in the example of the embodiment given in FIGS. 2, 3 and 4, 10 or 12 The knitting courses lie in the fact that each forms one repeat.

As shown, the pile yarns are partially knitted as open or closed loops. Further, the guide bar L2 supplies the front base fabric tissue thread 7 like the pillar stitch in the front base fabric structure 12, and the guide bar L5 connects the rear base fabric like the open pillar stitch in the back fabric structure. It is shown that a tissue thread 10 is provided. Here, it is understood that the guide bars L1 and L6 arrange the weft as shown in FIG.

FIG. 6 shows a single pile yarn having loops knitted like pillar stitches. The courses 16 and 17 from one side of the base fabric structure to the other side are cut by the cutting device 15 after the knitting process so that a nap pile having desired nap appears on the surface.

Numerous (mostly known) wrappings are suitable for the front and back fabric structures. FIG. 7 shows, for example, a double tricot in an anterior fabric fabric, underlapping in the opposite direction and overlapping in the same direction. This results in a resilient backing tissue that can be used, for example, for piloer in toys.

FIG. 8 shows a base fabric structure including an open pillar stitch formed by the guide bar L2 and a partial weft formed by the guide bar L1.
