Description

KNITTED PLUSH FABRIC AND DOUBLE-NEEDLE BAR WARP KNITTING MACHINE FOR PRODUCING SUCH FABRIC}

The present invention relates to a knitted knit fabric having a warp knit base structure comprising pile ends spaced from the base structure and a double needle bar warp knitting machine producing such a knit, the warp knitting machine having a rear base Seal guides (guide fingers) disposed on the rear needle bar forming the structure, seal guides (guide fingers) disposed on the front needle bar forming the front base structure, and the pile ends alternately on the rear and front needle bars. And a controller for controlling the thread guides (file guide fingers) for conveying the thread guides.

For all known flush knits, pile brushes are drawn relatively easily from the base structure. This is especially true for pile materials of less than 200 dtex. To some extent by proper post-treatment, for example thermal curing of a knitted fabric, the durability to which the pile brushes are drawn can be increased. However, such a method is not suitable for use in many fields of flush knitting.

A particular field of use is toy plush knits used to produce such things as animal toys. In particular, infants may play with the plush animal toys and put them in their mouths, with pile brushes being pulled out of the base and such synthetic fiber filaments may enter the stomachs of the infants. The stomach acid then solidifies the synthetic fibers into a glass that loses its flexibility and can injure the stomach.

Even in the case of flush knitted fabrics used for other purposes, a high durability for the pile brush to be pulled out of the ground structure is also required for improving the quality of the product.

It is an object of the present invention to provide a high durability for the pile brushes to be pulled out of the ground structure in the above-described type of flush knit.

According to the present invention, the problem for solving the above-mentioned problems with the above-mentioned flush knit is solved by crossing the pile ends at least twice as loops in the base structure between each of the two discharge places.

In such knits, each pile brush is maintained by crossing in at least two loops, and pulling out of the base structure becomes nearly impossible.

It is particularly advantageous to cross each pile end into at least three loops as loops in the groundwork between the respective discharge sites, thereby making particularly strong crossings.

It is preferable to form the pile end loops with an open or closed pillar stitch.

In other embodiments, the pile end loops may be formed of open or closed pillar stitches arranged in a row.

The infrastructure is simply composed of double tricot or Charmeuse. As a result, an elastic base structure is obtained.

Alternatively, it is also preferred that the base structure consists of pillar stitches and wefts, thereby obtaining a stronger base structure.

The invention also includes a double needle bar warp knitting machine of the kind described above in which the controller is arranged such that the pile ends intersect at least twice as loops in the front and back background structure between passages to each other needle bar.

Since the pile ends are deformed into a flush forming pile brush by the cutting of the pile ends on which tension is applied, the durability against the pulling of the pile brush is particularly important.

The controller that controls the placement of the pile ends is preferably adapted to perform the placement of the pile ends and the ends of the ground structure.

The present invention will be described in more detail below with reference to the accompanying drawings, preferred embodiments.

The double needle bar warp knitting machine shown in FIG. 1 includes a front (V) needle bar 1 and a rear (H) needle bar 2. The needles 3, 4 together with the other warp knitting elements are shown schematically in the knitting area. Six guide bars L1-L6 are provided, and their thread guides (guide fingers 5) feed the six rows of threads to the needles 3, 4 of the needle bars 1, 2. The threads 6, 7 of the guide bars L1, L2 form the front base structure 12, and the threads 10, 11 of the guide bars L5, L6 form the rear base structure 13. The pile ends 8, 9 fed by the guide bars L3, L4 are alternately arranged on the needle bar 1 and the other needle bar 2, forming an intermediate region 14, where the pile ends Are kept taut. The intermediate region 14 is later cut, for example by a flush cutter, so that the pile ends become pile brushes, forming the required flush. The controller S controls the guide bars L1-L6. The controller is arranged to perform the lappings described later.

In the schematic of the knitting operation below, it is important to understand that lapping is alternately made from one row to another on the front (V) needle bar 1 and the back (H) needle bar 2.

2 shows pile ends 8, 9 laid (wrapped) by guide bars L3, L4, which pile ends are laid as open pillar stitches. Two pile end loops 18 and 19 are provided between the two passages to the different needle bars, respectively, to cross the ground structure to securely secure the pile ends.

The embodiment shown in FIG. 3 is identical to the embodiment described above, except that the pile ends are laid (wrapped) as an open pillar stitch in the form of a ripple.

In the embodiment shown in FIG. 4, the three loops 18, 19, 20 intersect in the foundation between two successive passages 16, 17 so that the pile ends are more strongly fixed in the construction.

In FIG. 5, the guide bars L3, L4 are formed so that three loops 18, 19, 20 are formed between successive passages to both sides of the infrastructure, to cross the pile ends in the infrastructure, Place pile ends 8, 9. In the embodiments of FIGS. 2, 3 and 4, the warp knitting machine is repeated with 10 operating cycles, respectively, while in this embodiment there is an important difference in that it is repeated with 20 operating cycles between two horizontal lines.

As shown in the figure, the pile ends are formed as a partially open closed loop. Furthermore, the guide bar L2 feeds the base thread 7 to the front base structure 12 as a pillar stitch, and the guide bar L5 feeds the base thread 10 as a pillar stitch open to the rear base structure. . The guide bars L1 and L6 arrange the weft yarn as shown in FIG. 8.

6 shows a single pile end in which the loop formed is wrapped as a pillar stitch. Passages 16 and 17 from one side of the base structure to the other are cut by the cutter 15 at the end of the knitting process to form pile brushes to represent the required flush on the knit surface.

For the anterior and posterior base structures, many known wraps are suitable, mostly. FIG. 7 shows a double tricot with an overlap in the same direction as an underlap in the opposite direction with respect to the anterior base structure. This results in an elastic base structure that can be used, for example, for plush toys for toys.

FIG. 8 shows an open pillar stitch formed by the guide bar L2 and a base structure consisting of a weft yarn partially formed by the guide bar L1.

According to the present invention, each pile brush of the knit intersects with at least two loops, making it almost impossible to draw in the base structure, the base structure being composed of double tricot or Charmeuse The base structure is obtained, and the durability to the pull out of the pillar brush is particularly improved by cutting the pillar ends where tensile force acts when the pillar ends deform into a flush knit forming pile brush.
