Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for patterning a jacquard warp knitted fabric, in which the pattern yarn to be controlled by the jacquard is swung horizontally over four stitch rows or more on the base fabric. The purpose is to provide a warp knitted fabric having a linear pattern by varying the density of the number of threads on the fabric in the vertical and horizontal directions.

[Conventional technology, its problems, and issues to be solved]

Conventionally, the same number of pattern yarns as the ground yarns that constitute the base fabric are fed to the flanchin guide of the jacquard guide bar equipped on the jacquard warp knitting machine, and the yarns are fed parallel to the flanche guide. A reciprocating dropper bar is provided with a dropper whose vertical movement can be selected by controlling the pattern paper of the jacquard head, and is dropped between the flanch guides, and the flanchine guide is folded by the relative movement between the dropper bar and the jacquard guide bar. By bending the needle and changing the position of the pattern thread relative to the needle, overlapping parts of the pattern thread were created between the wales, and depending on the density, thick fabrics, thin fabrics, hollow fabrics, etc. were formed.

However, in the above method, when the pattern is expressed by the pattern yarn on the base fabric, the pattern yarn is laid flat on the surface of the base fabric, and there is little change in the overall knitted fabric, so the jacquard warp knitted fabric has a novel surface effect. development was requested.

The present invention was developed as a result of intensive research in order to meet the above-mentioned demands.

〔Example〕

The patterning method will be explained below using illustrations. Fig. 1 is a schematic side view showing the main parts of a jacquard warp knitting machine used for knitting a jacquard warp knitted fabric, in which 1 is a needle, 2 is a flanchin In the guides, a flanch guide 2 is attached to a jacquard guide bar 3, 4 and 5 are ground guides and are attached to ground guide bars 6 and 7, respectively, and 8 is a dropper bar that slides the dropper 9 up and down. The jacquard head (not shown) transmits motion to the thread 10 to cause the dropper 9 to fall between the flanch guides 2, thereby causing the dropper 8 and the jacquard guide bar 3 to move relative to each other. The Franchin guide 2 is bent by the movement〓〓〓〓
Ru. A drop plate 11 is provided between the ground guide bar 6 and the dropper bar 8.

Next, an example of pattern creation will be explained using an organization chart. In Fig. 2, 12 is a pattern yarn, which is fed from the flanking guide 2, 13 is a stitch yarn, which is fed from the ground guide 4, and 14 is a pattern yarn, which is fed from the ground guide 4. is an insertion connecting yarn, which is fed from the ground guide 5, and is threaded continuously for the number of needles 1. The points in the figure indicate the position of the needle 1, and the pattern yarn 12 is swung back and forth between the stitch rows W1 _{to W7 ,} and the pattern yarn 12 is swung back and forth between the stitch rows W1 and _W7 at both ends.
In W ₇ , the basic structure is such that it is wound around the needle 1, and in the knitting of the embodiment, the fall plate 11 is applied to the winding of the pattern yarn 12, so that it is inserted into the base fabric without forming a loop in the base fabric. Make it fixed. Note that if there is no falling plate, it will be fixed by forming a loop on the base fabric.

C ₁ to _{C 8} indicate each knitting course, and the pattern thread 12 is now
When the winding around the needle 1 is blocked by the arrow A of the C ₃ course, the pattern thread 12 is no longer fixed to the base fabric, and the pattern thread 12 is released from the base fabric to form the C ₂ course and the C ₄ course.
The pattern yarn 12a runs vertically between courses and becomes a straight line.

Also, when the winding around the needle 1 is blocked by the arrow B of the C ₆ course, the pattern thread 12 is no longer fixed to the base fabric in the same way, but moves to the left, and the pattern thread 12 is formed in a straight line between the C ₅ course and the C ₇ course. This becomes thread 12b.

As described above, one part of the right-hand folded part of the pattern thread 12 is prevented from being wrapped around the needle, and the other part is the part where the pattern thread 12 is swung back and forth between four stitch rows or more and laid on the base fabric. Patterns are created by providing appropriate courses,
Next, to explain specific knitting, Fig. 3 is a knitting organization chart showing a specific example of one pattern.
The structure of the stitch yarn 13 and the inserted connecting yarn 14 is omitted for clarity.

In the figure, P ₁ is a linear pattern part, in which 6 pattern threads 12 are swung horizontally to the right by 7 needles and fixed to the base fabric at the stitch rows at both ends, and the stitch rows W ₁ to _{W 10} in between are Five pattern yarns overlap in stitch rows W ₅ and W ₆ in the center part, and the number of overlapping yarns gradually decreases as one goes to end stitch rows W ₁ or W ₁₀ . or
P ₂ is also a linear pattern part, and 128 pattern threads are divided into 7
The needle is swung horizontally to the left and fixed to the base fabric at the stitch rows at both ends, and the number of overlapping threads is gradually reduced as the stitch rows in between W ₄ to _{W 15} are moved. As a result, each stitch row is a place where there is no pattern thread at all.
There are three types: P ₃ , a part P ₄ where only one thread is entwined individually, and a double part P ₅ where two threads are intertwined, and the pattern thread density also changes in the vertical direction.

As described above, in the pattern part, the overlapping density of the pattern threads is made lower as it goes from the center to the ends, so that the linear pattern has a slub thread-like appearance as shown in Figure 4. It is possible to provide a novel jacquard warp knitted fabric that also has a change in stitch row density in the direction.

Furthermore, the linear pattern P ₆ shown in Fig. 5 is a pattern thread formed by providing another jacquard guide bar and swinging the pattern thread 12 back and forth, and the horizontal density of the pattern thread is as shown in Fig. 4. It goes without saying that it is possible to create a linear pattern with even more volume, and if this is used in combination with one of the pattern threads produced by the above-mentioned pattern creation method, it will become even more innovative.

〔Effect of the invention〕

As explained above, the present invention uses a jacquard warp knitting machine that is equipped with at least two base guide bars forming a base fabric and at least one jacquard guide bar in front of the base fabric, Multiple pattern yarns fed to the chin guide,
The stitch rows formed by the stitch yarns fed by the guide bar forming the base fabric are simultaneously swung across four or more stitch rows in any knitting course, and some of these pattern yarns are unloaded onto the needles by jacquard control. As an action, the threads run in the vertical direction, and the remaining threads are entwined with the stitch rows and fixed to the base fabric to form a linear pattern in the horizontal direction, and in these stitch rows, the pattern yarns are double or single. Alternatively, by providing a non-existent part, the pattern is constructed by combining the vertical stitch row density with the horizontal linear pattern, so the horizontal linear pattern can be created in any course. In addition to being able to create patterns of any length, the linear pattern produces a pattern effect as if slub yarn was knitted from the horizontal direction of the base fabric, and together with the change in stitch row density in the vertical direction, It is possible to provide a jacquard warp knitting machine that exhibits a novel surface effect using pattern yarns that have never existed before.
