Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pile knitted fabric and a knitting method thereof.

[Problems to be solved by conventional technology/invention]

There is a method of knitting pile knitted fabrics using a warp knitting machine such as a latsiel knitting machine, but the conventional pile knitted fabric using a latsiel knitting machine is one of the three rows of reed bars. The warp threads are inserted into the thread guide holes of the reed bar located in the front row, the pile threads are passed through the thread guide holes of the reed bar located in the next row, and the weft threads are passed through the thread guide holes of the reed bar located in the last row to create a chain structure. The knitting was done by moving the reed bars back and forth and left and right. The knitted pile fabric had protruding loops and did not have the texture of being knitted by hand.

The present invention utilizes a warp knitting machine such as a ratchet knitting machine to knit pile fabric, and then uses a tentering machine to create width and at the same time shorten the length. An object of the present invention is to provide a pile knitted fabric having a texture and a knitting method thereof.

[Means for solving problems]

In order to achieve this object, the pile knitted fabric according to the present invention has pile yarns, warp yarns, and weft yarns, and the pile yarns alternately create closed loops and open loops in the warp direction for each course across each wale. While knitting, the closed loops and open loops are tightly bound by the warp yarns, and the weft yarns are wound around the closed loops and open loops.

Furthermore, the method for knitting a pile knitted fabric according to the present invention includes:
Using a warp knitting machine such as a Ratsiel knitting machine, which has flattened needles and sliders that move up and down, and three rows of reed bars that move back and forth and left and right, pile yarn is passed through the thread guide hole of the reed bar located in the front row, and then transferred to the next row. After knitting a pile fabric by passing the warp thread through the thread guiding hole of the reed bar located at the position and the weft thread through the thread guiding hole of the reed bar located at the last row, the width of the pile fabric is made using a tentering machine. At the same time, it is characterized by shortening the length.

〔Example〕

Hereinafter, the present invention will be specifically described based on embodiments shown in the drawings.

As shown in FIG. 7, the pile knitted fabric according to the present invention is made by alternately braiding closed and open loops of pile yarn 6 in each course in the warp direction across each wale. The closed loops 9 and the open loops 10 are tightly bound by the warp threads 7, and the weft threads 8 are wound around the closed loops 9 and the open loops 10. The knitted product differs from conventional products in which the pile threads stand out from the ground knitting, giving it the appearance of hand-knitted stockinette knitting.

Next, a method for knitting such a pile knitted fabric will be explained based on FIGS. 1 to 6. In the figure, in the front, back, left, and right directions, when the latch needle 1 and the slider 2 are lined up, the slider 2 side is the front, and the latch needle 1 side is the rear. In FIG. 6, the slider 2 is omitted to make it easier to see how the pile yarns are knitted.

Among the three rows of reed bars L1, L2, and L3, the pile yarn 6 is inserted into the thread guide hole 3 of the reed bar L1 located in the front row, and the warp thread 7 is inserted into the thread guide hole 4 of the reed bar L2 located in the next row. , the thread guiding hole 5 of the reed bar L3 located in the last row
A weft thread 8 is inserted through each.

In the present invention, the latch needle 1 and the slider 2
moves up and down in the directions of arrows P and Q, while the reed bar L
1, L2, and L3 move back and forth in the directions of arrows R and S, and also move left and right by rearranging the chain structure to knit the pile fabric A. By the way, conventionally, in pile knitting using a latsiel knitting machine, the warp threads 7 are generally inserted into the thread guiding holes 3 of the reed bar L1 located in the front row.
The pile yarn 6 is inserted into the thread guide hole 4 of the reed bar L2 located in the next row, and the weft thread 8 is inserted into the thread guide hole 5 of the reed bar L3 located in the last row, and the chain structure is rearranged. However, in the case of the present invention, the pile yarn 6,
The warp threads 7 are inserted into the thread guiding holes 4 of the reed bar L2 located in the next row.
The weft 8 is inserted into the thread guide hole 5 of the reed bar L3 located in the last row.
The knitting is done by inserting the threads through the respective thread guide holes 3 and 4 of the reed bars L1 and L2, and the difference in the threads passing through the thread guide holes 3 and 4 of the reed bars L1 and L2 appears in the knitted product.

First, the pile yarn reed bar L1, the warp yarn reed bar L2
After the weft reed bar L3 moves forward in the direction of arrow R and the slider 2 moves upward in the direction of arrow P and reaches the highest position, the pile yarn reed bar L1 moves from left to right by one stitch. , reed bar L for pile yarn
1. The warp reed bar L2 and the weft reed bar L3 are reversed and moved backward in the direction of arrow S. During the backward movement, the pile yarn 6 engages with the slider 2 as shown in FIG. move through. Next, after the pile yarn reed bar L1, the warp yarn reed bar L2, and the weft yarn reed bar L3 reach the rearmost end of the backward movement, the pile yarn reed bar L1, the warp yarn reed bar L2, and the weft yarn reed bar L3 It is reversed and moves forward again in the direction of arrow R, and the latch needle 1 moves upward in the direction of arrow P. Next, when the latch needle 1 reaches the highest position, the pile yarn reed bar L1, the warp reed bar L2, and the weft reed bar L3 are reversed and move back in the direction of the arrow S, passing between the latch needles 1 and 1. Moving. When the pile yarn reed bar L1, the warp yarn reed bar L2, and the weft yarn reed bar L3 reach their rearmost ends, the pile yarn reed bar L1 and the warp yarn reed bar L2 chain from right to left for one stitch. The pile yarns 6, which are moved by the structure and passed through the pile yarn reed bar L1, and the warp yarns 7, which are inserted through the warp yarn reed bar L2, move to the needle head 1 of the flat needle 1.
a, the pile yarn reed bar L1, warp yarn reed bar L2, and weft yarn reed bar L3 are reversed again and moved forward in the direction of arrow R, and then reversed again and moved backward in the direction of arrow S. Next, the latch needle 1 moves downward in the direction of the arrow Q, and a stitch is formed by the pile thread 6 and the warp thread 7, which were engaged with the latch needle 1, and the slider 2 moves downward in the direction of the arrow Q, reaching the lowest position. When it reaches this point, the weft reed bar L3 moves from right to left by three stitches in a chain weave, and one stitch of pile fabric A is knitted.

Next, similarly, the pile yarn reed bar L1, the warp yarn reed bar L2, and the weft yarn reed bar L3 move forward in the direction of arrow R, and the slider 2, which has moved upward in the direction of arrow P, reaches the highest position, and the pile yarn reed bar L2 moves forward in the direction of arrow R. The bar L1, the warp reed bar L2, and the weft reed bar L3 are reversed and moved backward in the direction of arrow S, passing between the flat needles 1 and 1. Note that the pile yarn reed bar L1 forms a pile every other stitch, and this time it only passes between the flat needles 1 and 1 and is not knitted into the warp yarns 7. Next, the pile yarn reed bar L1, the warp yarn reed bar L2, and the weft yarn reed bar L3 are moved backward, then reversed and moved again toward the arrow R.
At the same time, the latch needle 1 moves upward in the direction of arrow P. Then, when the latch needle 1 reaches the highest position, the pile yarn reed bar L1, the warp reed bar L2, and the weft reed bar L3 move backward in the direction of arrow S, passing between the reversed latch needles 1 and 1 again. do.
Then, the pile yarn reed bar L1, the warp yarn reed bar L
2 and when the weft reed bar L3 reaches the rearmost end, the warp reed bar L2 moves from left to right by one stitch by the chain structure, and the warp thread 7 that has been passed through the warp reed bar L2 reaches the end of the flat needle 1. After engaging the needle head 1a, the pile yarn reed bar L1, warp yarn reed bar L2, and weft yarn reed bar L3 are reversed again and moved forward in the direction of arrow R, then reversed again and moved backward in the direction of arrow S. do. Next, the latch needle 1 moves downward in the direction of arrow Q, and a stitch is formed with the warp threads 7 that have been engaged with the latch needle 1, and at the same time, the slider 2 moves downward in the direction of arrow Q and reaches the lowest position. , the weft reed bar L3 moves three stitches from left to right in a chain weave, and one stitch of the pile fabric A is knitted.

Thereafter, repeat the above operation. Note that w in the figure represents a wire.

Then, pile fabric A knitted by the above operation
A pile knitted fabric is created by using a tentering machine to increase the width and simultaneously shorten the length. For example, after cutting the knitted pile fabric to a width of approximately 1.75 to 1.8 m and a length of approximately 50 m, the width is increased using a tentering machine and at the same time the length is shortened to create a product approximately 2.2 m wide and 35 m long. When using a knitting machine, it is most preferable to increase the width and shorten the length at the same time in terms of knitting the pile fabric.

In this way, a pile knitted fabric as shown in FIG. 7 can be knitted.

〔Effect of the invention〕

In conventional pile knitted fabrics, the pile yarns stand out from the ground knitting, and do not have the texture of being knitted by hand. However, in the case of the present invention, by performing a new method of recombining the chain structure, changing the arrangement of pile yarns and warp yarns, and using a tenter to increase the width and simultaneously shorten the length, the knitted product can be made into a knitted product. It is possible to create a texture similar to that of a hand-knitted stockinette stitch, which was previously impossible.

In addition, in the case of the present invention, since the pile yarn is knitted every other stitch, the basis weight of the knitted fabric is slightly increased, and the lateral elongation can bring out the characteristics.
