[Detailed description of the device]

[0001]

Industrial Field The present invention is suitable for women's underwear, marine sports, athletic sports, and widely as an accessory for general sports clothing. It relates to a warp knitted fabric.

[0002]

2. Description of the Related Art Conventionally, various wide elastic warp knitted fabrics for foundation materials or sports clothing have been devised, and particularly satin-like elastic fabrics have become mainstream. While such elastic warp knitted fabrics have been developed, a stretchable narrow tape having a corresponding dense surface effect has been demanded. Stretchable narrow width warp knitted fabrics that have an effect of pulling yarn have been researched and developed. These have the same feeling, physical properties, color tone, surface effect, etc. as the body material to be used, and they have been one of the methods for producing tapes of this type until then. Compared with the "cut" method, problems such as formation of ears and fraying of ears after washing were solved, and it seemed that a tape in good condition was obtained.

[0003]

However, in such a conventional tape, since the knitting structure forms a stitch similar to that of the wide elastic fabric used for the body material, the tape itself has a longitudinal direction. In addition to extensibility, it also has extensibility in the weft direction, which is essentially unnecessary. Therefore, when the force is released after the tape has been stretched in the warp direction to some extent, the tape bends in the weft direction, which causes a problem in sewing work.

Further, in order to improve the problems of the conventional method in which a desired narrow width is cut by an appropriate cutting tool, the present inventors have disclosed in Japanese Utility Model Publication No. 63-11196. In addition to devising the interposition of the pulling thread, when the pulling thread is removed, the elastic thread that is entangled in the pulling thread shrinks to form smooth ears, and a beautiful tape-like shape that does not cause fraying. It has been found that an elastic narrow knitted fabric can be obtained. However, since this elastic narrow knitted fabric is knitted by interposing one selvage knitting yarn on each of the left and right edges at the joint edge of the knitting yarn structure, due to the structure of stitch formation, an extra yarn is used. Are required, and there are problems such as an increase in cost. In addition, the elastic thread
When pulling out the pull-out thread, the thread is often entangled.
The frictional resistance of the entangled part increases and the elastic narrow knitted fabric
Shrinks greatly in the pulling direction, making the pulling work efficient
There was a problem that it could not be done well .

[0005] The present invention is intended to eliminate the above-mentioned conventional problems, a beautiful stretch narrow width for warp knitted fabric corresponding to the wide satin elastic fabric, eliminating the curvature of the post-stretch recovery of the tape As a result, the sewing work proceeds smoothly, and by eliminating the selvage knitting yarn that is originally excessive from the knitting machine , the knitting work can be simplified and the product price can be reduced. In addition, it is an object of the present invention to provide a stretchable narrow width warp knitted fabric in which the pulling operation of the drawn yarn can be smoothly performed .

[0006]

In order to achieve the above object, the stretchable narrow warp knitted fabric of the present invention comprises one or two ground knitting yarns 11 and 12 made of a synthetic fiber strip for each course. In Wales
When knitting while forming a loop that transitions in a zigzag shape
Both of these knitting yarns 11 and 12 are knitted with an elastic yarn 21 to form knitting yarn structures 1 and 2 having a constant narrow width.
There should be no interlaced yarn on both side edges of the base knitting yarn structures 1 and 2 .
The elastic yarns 22 and 22 for the ear hooking yarns are inserted and knitted, and the elastic yarns 2 for the ear hooking yarns of the adjacent knitting yarn structures 1 and 2 are formed.
A warp knitted fabric structure A is formed by interposing a draw thread 31 between the two and 22, and a part of the elastic yarns 22, 22 for the ear hooking thread is provided to the draw thread 31 once every 3 to 5 courses. It has a entangled structure.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. 1 is a base knitting yarn 11, 12 made of synthetic fiber, an elastic yarn 21,
A wide-width warp knitted fabric structure A is formed by connecting a large number of the narrow-width ground knitting fabrics by knitting with the selvage elastic yarns 22 Are organized.

As shown in FIG. 4, the knitting of the ground knitting yarn 11 forms a closed or open loop in the first course and moves to an adjacent wale in the second course to form a closed or open loop. After that, it returns to the original wale again to form a closed or open loop, and this is repeated to knit. That is, a zigzag loop is formed by moving to adjacent wales for each course and forming a closed or open loop. In addition, in FIG. 4, a closed eye is shown.

The knitting of the ground knitting yarn 12 is as shown in FIG.
In the 1st course, a closed or open loop is formed. In the 2nd course, it moves to the right or left between the two stitches to form the open or closed loop, and then returns to the original wale again. Similarly, a closed or open stitch is formed, and this is repeatedly knitted. That is, a zigzag-shaped loop is formed by moving to a wale that has jumped between two stitches for each course and proceeding while forming a closed or open loop. In the loop formation of the ground knitting yarn 11 and the ground knitting yarn 12, the stitches are sequentially formed from the first course in a shape that is nearly symmetrical.

As shown in FIG. 7, the elastic yarn 21 having elasticity inserted into the knitting yarns 11 and 12 of the knitting yarn structures 1 and 2 runs on the left side of the needle in the first course, and then, After running on the right side of the needle in the course of 1, the zigzag-shaped insertion tissue is formed to travel back to the original wale again. The insertion structure of the elastic yarn 21 is the insertion structure most commonly used for tricot elastic fabric.

The elastic yarns 22 and 22 for the ear hooking yarns are inserted into both side edges of the knitting yarn structures 1 and 2 of each place, and the pulling yarn 31 is the elastic yarns for the ear hooking yarns of the adjacent knitting yarn tissues 1 and 2. It is intervening and knitting between 22 and 22. The elastic threads 22 and 22 for the ear hanging thread are shown in FIG.
As shown in FIG.
As shown in, on the first course, it travels on the left side of the needle, on the next course it moves to the wale that flies to the right between the two stitches, and on the next course it returns to the original wale and on the left side of the needle. To drive. Furthermore, after that, the zigzag-like running is repeated only between one stitch, and when 3 to 5 courses have been advanced, this time, the course travels two stitches to the left, which is the opposite direction to the second course, and then runs again on the next course. The insertion structure is formed by returning to the original wale and running, and thereafter, repeating zigzag running for only one stitch until the wale transition between two stitches is performed again in the third to fifth courses. In each of the attached drawings, the elastic yarns 22 and 22 for the ear hooking yarn have an insertion structure that skips once between two needles every five courses.

As shown in FIG. 1, the unthreaded yarns 31 are elastic yarns 22 and 32 for ear hooking yarns on the left side adjacent to each other in the second course from the bottom.
Entangle at position 3 and then entangle at the position of 33 with the elastic thread 22 for the ear hook thread that is adjacent to the right side in the portion advanced by 3 to 5 courses. The elastic yarns 22 and 22 for knitting are knitted after only one needle while being entwined with each other, and the ground yarn structures 1, 2, 1, 2, ... Then, a wide warp knitted fabric structure A is knitted.

When the punching plate 31 is pulled out, the elastic thread 22 for the ear hooking thread at the edge which is entangled with the pulling thread 31,
Since 22 is an elastic yarn, it elastically contracts and is wrapped in the ear portion formed by the knitting yarns 11 and 12 as shown in portions 32 and 33 in FIG. Further, as shown in FIG. 1, the unthreaded yarn 31 is entwined with the elastic yarn 22 of the portions 32 and 33 that fly two wales of the left and right tapes every 3 to 5 courses (5 courses in the embodiment and each drawing) while opening. It can be easily removed because it is a chain knitted structure, and smooth ears are formed by the contraction of the picot part of the elastic yarn 22, and it has elasticity that looks like it was cut with a sharp blade. A ribbon-shaped narrow fabric is obtained, and this ribbon-shaped tape is used for the ground knitting yarn structures 11, 12
Due to the structure of loop formation, even if the force is released after being stretched to the limit, it never bends, and a beautiful ribbon-like stretchable narrow warp knit fabric that does not cause any difficulty in sewing work is obtained. It is what is done.
