It relates to a method for manufacturing and a new patterned warp knitted fabric.

2. Description of the Related Art A warp knitting machine having such a jacquard controller is described in a book by Wartz knitting production.
(Warp knitting) ", pp. 304-308 published in 1987, where a pattern yarn guide needle displaceable by one knitting needle is supported by a pattern guide bar system,
This pattern guide bar system gives the pattern guide bar the same basic displacement operation under two knitting needles, that is, the stroke between the two knitting needles. This results in density differences due to various overlapping combinations that can be used for patterning. DE 196 51 05 not previously published
In a warp knitting machine with a jacquard control that can be read from 3.8-26, a jacquard controlled guide needle can occupy three stable positions. For this purpose, the guide needle can be reciprocated between two end positions having a distance equal to twice the distance between the needles by the operating part of the needle control device. In addition, additional stops are provided, which can be displaced in the course of the guide needle by means of a control of the stop control device, thereby holding the guide needle in a central position.

An object of the present invention is to provide a new warp knitting machine for knitting, a new patterning method based on the warp knitting machine, and a warp knitted fabric thereby. is there.

This object is achieved, with regard to the device, by a warp knitting machine according to the invention (claim 1). With such a warp knitting machine, it is possible to realize a warp knitted fabric having at least three steps of thick and thin patterning or two-color patterning as described below. The important thing at that time is
It is a combination of a large total displacement movement under four or more knitting needles that allows knitting of thick pattern areas or the appearance of colors, and a guide needle and a basic displacement movement that can occupy more than two positions. This is because a distinct gradation or fine transition from one color to the other is possible between the different densities of the pattern area. In another configuration (Claim 2), the chain stitch is supplied by a single ground guide bar, and these chain stitches are combined with the pattern yarn to form a base fabric, and from the plain patterning by appropriate guide of the pattern yarn. It is possible to shift to net design. According to still another configuration (claim 3), 3
It is possible to generate a handle region having a thick and thin handle and a float. According to still another configuration (claim 4), it is possible to provide a total displacement operation under five knitting needles and to achieve an appropriate gradation for thick and thin patterning. With a special arrangement of the ground guide bar (claim 5), a pattern is obtained in the base cloth.
In another arrangement of the ground guide bar (claim 6), a handle mounted on the base cloth is obtained. In still another configuration (claim 7), the pattern yarn guide needle can be supplied with a full gauge. Despite the need for structural elements for multi-position positioning, the handle thread guide needles do not interfere with each other. In still another configuration (claim 8), the number of guide needles is only 50% of the number of knitting needles. In this manner, stepwise patterning can also be achieved. According to still another configuration (claim 9), three positions of the pattern thread guide needle can be provided without difficulty. The second operating part preferably moves across the direction of displacement movement. In particular, the operating part can be a piezoelectric bending transducer as described in detail in DE 196 51 053.8. With regard to the method, the solution to the problem raised is the method of the invention (Claim 1).
0). The chain stitch structure of the ground yarn (claim 11) is possible because the chain stitch is connected by the pattern yarn. The patterning step is enlarged by an additional feature of the invention (claim 12). According to the additional feature (claim 13), it is possible to shift from plain pattern printing to net pattern printing. Characteristic wrapping format (Claim 1
According to 4, 15), the pattern yarn can be involved in the formation of the base fabric, but a completely different pattern appearance can be obtained visually. According to yet another feature (claim 16), a very outstanding thick and thin pattern is obtained. According to yet another feature (claim 17), a very effective two-color patterning can be achieved. Warp knitted fabric of the present invention (Claim 18)
Is a novel patterned warp knitted fabric that produces patterned areas of different thickness or density depending on the number of patterned yarns in the underwrap. In other warp knitted fabrics (claim 19), the number of stages is increased. Yet another warp knitted fabric (claim 20) provides a transition from a plain pattern to a net structure. Another warp knitted fabric of the present invention (claim 21) specifies a novel warp knitted fabric having a two-color patterning. If only one color is in the underlap, this color will appear clearly. If both colors are in the underlap, gradual mixing will occur.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on preferred embodiments with reference to the drawings. The knitting area 1 of the warp knitting machine shown in FIG. The ground yarn 4 supplied at full gauge is supplied via a ground yarn guide needle 5 attached to a ground guide bar 6. The ground guide bar 6 can be reciprocated with a tricot knit structure, for example. However, when the ground guide bar 6 knits a chain stitch, it is preferable to use a pattern yarn 7 described below to generate a continuous base cloth. The pattern thread 7 is supplied via pattern thread guide needles 8 arranged in four displacement operation rows 9, 10, 11, 12 every ご と gauge, and the displacement operation rows are held by the support 13. The pattern yarn guide needle 8 is arranged in a full gauge on the pattern guide bar system 14 thus obtained. This system undergoes a common elementary displacement movement, for example, under three knitting needles 2 (FIG. 6) or two knitting needles 2 (FIG. 7). It is the basic displacement applying device 15 that provides this basic displacement operation, and the pattern yarn guide needle 8
It is the jacquard controller 16 that causes the displacement.
The arrangement of the guide needle 8 in FIG. 1 is shown enlarged in FIG. The ground yarn guide needles 5 are located between the knitting needles 2 and the pattern yarn guide needles 8 arranged in four displacement operation rows. In the embodiment of FIG. 3, only two displacement operation rows of the pattern thread guide needle 8 are provided, and the pattern thread is only arranged by a half gauge. In the embodiment of FIG. 4, the ground yarn guide needle 5 is on the opposite side of the pattern yarn guide needle 8 from the knitting needle 2, and is separated from the pattern yarn guide needle by the drop plate 17. Thereby, when a pattern yarn is arranged with a full gauge, drop board patterning can be achieved. In the other embodiment shown in FIG. 5, only two displacement operation rows having the pattern thread guide needle 8 are provided, but otherwise correspond to the structure of FIG. The pattern thread guide needle 8 can be moved by the jacquard control 16 to three different stable positions, each of which is offset from one another by one stitch 18. These three positions are represented by the letters R (right), M (center) and L (left) in FIGS. When the basic displacement operation on the three knitting needles 2 is combined with the three-position control of the pattern yarn guide needle 8, the possibility of the total displacement operation specified in the rows a to e of FIG. 6 is obtained. When the pattern thread guide needle 8 maintains its position, the total displacement operation coincides with the basic displacement operation (row a). 4 when switching from the right position to the center position at the left end
The total displacement operation under the five needles (row b) is obtained, and when the left end is switched to the left position, the total displacement operation under five knitting needles (row c) is obtained. On the other hand, when switched to the center position at the right end, the total displacement operation only proceeds under two needles (d column), and when switched to the left position at the right end, the total displacement operation under one needle is increased. The operation (column e) is obtained. On the other hand, if the basic displacement operation under only two needles is selected,
The possibility shown in FIG. 7 is obtained. The total displacement motion is below two needles (row f), below three needles (row g), below four needles (row h), below one needle (row i), and It can be obtained under zero needles (this corresponds to a float; row j). The possibility of achieving the three stable positions of the pattern thread guide needle 8 becomes apparent from FIGS. A first operation unit 19 and a second operation unit 20 are arranged on the support 13, and both can be operated from the jacquard control device 16. These operating parts are configured as piezoelectric bending transducers. The pattern thread guide needle 8 is fixed to the first operation portion 19, and can reciprocate in the direction of displacement by this operation portion. The operation unit 20 can be moved across this,
A stopper block 21 that can move from the position in FIG. 9 to the position in FIG. 10 and vice versa is supported at the lower end. The stopper block 21 has four stoppers fixed in the bar direction. 9, the left end stopper 22 and the center first stopper 23 are effective, and in the position of FIG. 10, the right end stopper 24 and the center second stopper 25 are effective. For other details, reference can be made to DE 196 51 053.8.
In the organization diagrams of FIGS. 11 to 16 described below, the chain stitch formed by the ground yarn 4 is not shown. The thin solid line corresponds to the basic displacement operation of the pattern guide bar system 14, and the thick solid line corresponds to the actual gradient of the pattern thread 7. The organization chart of FIG. 11 is shown in FIG.
The pattern yarn 7 is formed under the two knitting needles in the region d, under one knitting needle in the region e, and in the region e. The yarn is supplied as a partial weft under four knitting needles in the area b, under three knitting needles in the area a, and under five knitting needles in the area c. The display of the area in this case corresponds to the column display of FIG. As can be clearly seen, the number of underlaps between adjacent wales is significantly different.
The thickness of the pattern decreases from the area c to the area e through the area b, the area a, and the area d. As a result, a four-step thick and thin plane pattern having an extremely thick region, a thick region, an average region and a thin region is obtained. In the region e, the pattern thread 7 extends along the chain stitch, and an opening or a net portion can also be formed in the pattern. The organization diagram of FIG. 12 is also manufactured by the needle arrangement of FIG. The basic displacement motion suggested by the thin line is
It proceeds on the two knitting needles 2 as in FIG. Here, in the area j following the area i in which the total displacement operation proceeds under one needle, the pattern thread 7 is set as a floating thread. Next, a region f having a total displacement operation under two knitting needles, a region g having a total displacement operation under three knitting needles, and a region h having a total displacement operation under four knitting needles. There is. Accordingly, three areas f, g, and h, in which the number of underlaps of the pattern yarn 7 extending between adjacent wales gradually increases, that is, three-step thick and thin plane patterning can be obtained. 13 is also produced with the needle arrangement of FIG. 2 and has the three-stage basic displacement movement of FIG. 6, in which the pattern yarns 7 (solid lines), 7 of different materials, in particular of different colors, are shown. '(Dashed lines) are alternately woven. "color"
The expression also includes any other possibilities conceivable for various materials, including, for example, matte patterned yarn, glossy patterned yarn.
In the area l, the pattern yarn 7 is supplied under the five knitting needles,
The pattern thread 7 'is fed only under one knitting needle. The pattern yarn 7 forms two underlaps between adjacent wales and appears in a distinct color, while the pattern yarn 7 'fed along the chain stitch is hardly visible. A similar situation is obtained in the area m, where the pattern thread 7 'is fed under four knitting needles, and the pattern thread 7 is fed under one knitting needle. Here, two colors clearly appear. The intermediate stage is obtained in the areas n, o, where one handle yarn is fed under three knitting needles,
The other handle yarn is fed under one knitting needle. Other combinations providing various mixing effects can still be formed using the three positions of the pattern yarn guide needle. 14 is manufactured with the needle arrangement of FIG. 3 and has a basic displacement operation under three knitting needles 2, in which knitting needle 2 and ground thread guide needle 5 have full gauge, Both displacement rows of the pattern thread guide needle 8 jointly only have a half gauge. A region a having a total displacement operation under the three knitting needles is followed by a plurality of mixed regions having different total displacement operations in the weft direction. Areas a and e where the total displacement operation under three knitting needles and the total displacement operation under one knitting needle alternate.
And the areas b, c, d, and e where the total displacement operation under the four, five, two and one knitting needles is adjacent, and under the three, two and five knitting needles Are obtained in the regions b, a, and c where the total displacement operation is provided in the weft direction. The connection region e has a total displacement operation under one knitting needle, and the region c has a total displacement operation under five knitting needles. In this way, a two-stage thick and thin plain pattern with half the number of pattern yarns is obtained. The organization diagram of FIG. 15 is manufactured with the needle arrangement of FIG. 4 and is processed with a basic displacement operation under three knitting needles. Due to the patterning of the falling plate, the pattern yarns 7 are joined by loops to the stitches of the chain stitch formed by the ground yarns 4. Again, a region d having a total displacement operation under two knitting needles, a region e having a total displacement operation under one knitting needle, and a region b having a total displacement operation under four knitting needles A region a having a total displacement operation under three knitting needles, a region c having a total displacement operation under five knitting needles, and other regions a and f are obtained. From this, a four-tiered and thin pattern can be obtained visually on the surface of the cloth thanks to the drop plate. The pattern yarn forms a true chain stitch in the region e, and a shifted chain stitch in the region f. Therefore, a net structure is also possible. 16 is manufactured with the needle arrangement of FIG. 5 and has a basic displacement movement under the three knitting needles shown in FIG. Here, a zone a with a total displacement action under three knitting needles 2 is followed by a mixed area a, e, where a total displacement action under three knitting needles and a total displacement action under one knitting needle. The displacement operation alternates. In the subsequent mixing regions b, c, a, and d, the total displacement operation under the four, five, three, and two knitting needles is continuous in the weft direction. In the mixing regions b and a provided thereafter, the total displacement operation under four knitting needles and the total displacement operation under three knitting needles are continuous. Next comes region e, which has a total displacement movement under one needle, from which chain knitting of patterned yarns is also formed. Then, the area c of the total displacement operation under the five knitting needles comes. Also from this, a two-step thin pattern can be obtained on the surface of the cloth with half the number of pattern threads. In many cases, it is sufficient to generate a pattern by the above measures alone. However, additional effects can be achieved by adding other known patterns. As shown in FIGS. 14 and 16, the patterning changes not only in the warp direction but also in the weft direction. This is shown in FIGS.
This also corresponds to the case of performing the patterning according to FIG. 13 or FIG.

According to the present invention, it is possible to realize a warp knitted fabric having at least three steps of thick and thin pattern design or two-color pattern design.
