Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stretchable narrow-width warp knitted fabric which is suitable for women's underwear, marine sports, athletic sports, and widely as an accessory for general sports clothing even when the tape is not bent even when stretched and recovered. Is.

[0002]

[Prior art]

 A wide variety of elastic warp knitted fabrics have been devised for foundation materials or sports clothing, and satin-like elastic fabrics have become the mainstream. While such elastic warp knitted fabrics have been developed, a stretchable narrow tape having a corresponding dense surface effect has been demanded, and in the same way as the satin-like elastic fabric used for the body fabric, Research and development have been carried out on warp knitted fabrics for drawable intervening type, which have a surface effect, and which are intercalated by a drawn yarn. These have the same texture, physical properties, color tone, surface effect, etc. as the body material to be used, and they were one of the methods of manufacturing tapes of this type until then. Compared with the “cutting” 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]

[Problems to be solved by the device]

 However, since such a conventional tape forms a stitch similar to the wide elastic fabric used for the body fabric in the knitting structure, the tape itself is originally unnecessary together with the longitudinal stretchability. It also has extensibility in the weft direction. Therefore, when the force is released after the tape is 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 solve the problem of the conventional method in which a desired narrow width is cut by an appropriate cutting tool, the present inventors describe in Japanese Utility Model Publication No. 63-11196. In this way, while devising the interposition of the drawn thread, when the drawn thread is removed, the elastic thread entangled in the drawn thread contracts and smooth ears can be formed, and a beautiful tape-like shape with no fraying is formed. 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 of the joint knitting edge of the knitting knitting fabric due to the structure of stitch formation, an extra yarn is formed. Are required, and there are problems such as increased costs.

The present invention eliminates the above-mentioned problems of the prior art, and provides a beautiful stretchable narrow warp knitted fabric corresponding to a wide satin-like elastic fabric, and further, to extend and recover the tape. By eliminating the curving afterward, the sewing work proceeds smoothly, and by eliminating the selvage knitting yarn that is originally excessive on the knitting machine, the knitting work is simplified and the product price is reduced. The purpose of the present invention is to provide a warp knitted fabric for stretchable narrow width which can contribute to cost reduction.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the warp knitted fabric for stretchable narrow width of the present invention has a constant narrow width knitting yarn structure formed by inserting and knitting elastic yarn 21 into the knitting yarns 11 and 12 made of synthetic fiber strips. Elastic yarns 22 and 22 for selvage hooking yarns are inserted and knitted on both side edges of 1 and 2, and a knitting yarn 31 is interposed between the elastic yarns 22 and 22 for selvage hooking yarns of adjacent ground knitting yarn structures 1 and 2. The knitting is performed to form a warp knitted fabric structure A, and further, a part of the elastic yarns 22, 22 for ear hooking yarn is entangled with the drawn yarn 31.

[0007]

[Action]

 By entwining a part of the elastic yarn 22, 22 for the ear hooking yarn with the drawn yarn 31 once every 3 to 5 courses, the drawn yarn 31 can be easily removed and removed, and the drawn yarn 31 is removed. In doing so, a beautiful tape-like elastic narrow knitted fabric is obtained in which the edge portion becomes a smooth ribbon shape and does not cause fraying. Furthermore, by forming the structure of the ground knitting yarn structure into a loop in which the ground knitting yarns 11 and 12 move in zigzag shape to the wale of 1 to 2 per course, the elastic thin film which does not bend when the tape is recovered. It can be a wide knitted fabric.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. 1 is a ground knitting yarn having a constant narrow width formed by knitting a ground knitting yarn 11, 12 made of a synthetic fiber thread, an elastic yarn 21, and an elastic yarn 22 for ear hooking yarn. A wide width warp knitted fabric structure A is knitted by connecting a large number of the narrow width knitted fabric structures through the drawing yarn 31.

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 for knitting. 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.

Further, as shown in FIG. 5, the knitting of the ground knitting yarn 12 forms a closed or open loop in the first course, and in the second course, a wale that flies right or left between two stitches. After forming the open or closed stitches by moving to No. 2, the original wale is returned to again to form the closed or open stitches, and this is knitted repeatedly. That is, a zigzag loop is formed which moves to a wale skipped by two stitches for each course and advances 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 which is almost symmetrical.

As shown in FIG. 7, the elastic elastic yarn 21 inserted into the local knitting yarns 11 and 12 of the background knitting yarn structures 1 and 2 runs on the left side of the needle in the first course, and After running on the right side of the needle in this course, it returns to the original wale again and forms a zigzag insertion tissue. 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 pull-out yarn 31 is the elasticity for the ear hanging yarns of the adjacent ground knitting yarn tissues 1 and 2. The yarns 22 and 22 are interposed and knitted. As shown in FIG. 1, the elastic yarns 22 and 22 for the ear hooking yarn are inserted into both side edges of the knitting yarn structure of each place, and as shown in FIG. On the course, the vehicle moves to the wale that has flown to the right between the two stitches, and then returns to the original wale and runs on the left side of the needle on the next course. Furthermore, after that, repeating the zigzag-like running for only one stitch, when 3 to 5 courses have been advanced, this time, it runs for 2 stitches to the left, which is the opposite direction of the 2nd course, and runs again on the next course. It is an insertion structure in which the vehicle travels back to the original wale, and thereafter, zigzag traveling is repeated only for one stitch until the wale transition between two stitches is resumed 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 in which every two courses are skipped by two stitches.

As shown in FIG. 1, the drawn yarn 31 is entangled at the positions of the left side elastic yarns 22 and 32 for the ear hooking yarn which are adjacent to each other in the second course from the bottom, and then proceeded for 3 to 5 courses. One needle is entwined with the elastic yarns 22 and 22 for the ear hooking yarns on the left and right in sequence every 3 to 5 courses, such as being entangled at the position 33 with the elastic yarn 22 for the ear hooking yarns that are adjacent to the right side. The knitted fabric is knitted after that, and the narrow yarn ground fabrics 1, 2, 1, 2, ... It is what

Then, when the punching plate 31 is pulled out, the elastic yarns 22, 22 for the ear hooking yarn at the edge which are entangled in the pulling yarn 31 elastically contract because they are elastic yarns, 32 in FIG. As shown in the 33rd part, the knitted yarns 11 and 12 are incorporated into the ear part formed of the textures. Further, as shown in FIG. 1, the unthreaded yarn 31 is opened while being entwined with the elastic yarn 22 of the portions 32 and 33 of the left and right tapes that fly over two wales every 3 or 5 courses (5 courses in the examples and drawings). Since it is a chain knitted structure that is organized by the eye, it can be easily removed, and the smooth ears are formed by the contraction of the picot part of the elastic yarn 22, and it has the appearance as if it had been cut with a sharp blade. A ribbon-like narrow fabric having the property of being formed is obtained. Furthermore, due to the structure of the loop formation of the knitting yarn structures 11 and 12, this ribbon-like tape never bends even after the force is released and then the force is released. It is possible to obtain a beautiful ribbon-like stretchable narrow width warp knitted fabric that does not cause difficulty in sewing work.

[0015]

[Effect of device]

 As described above, according to the warp knitted fabric for stretchable narrow width of the present invention, the elastic yarns 22 and 22 for the ear hooking yarns are knitted and inserted to both side edges of the base knitting yarn structures 1 and 2 having a constant width. The knitting structure is obtained by entwining a part of the elastic yarns 22 and 22 for the ear hooking yarn with the drawn yarn 31 interposed between the elastic yarns 22 and 22 for the ear hooking yarn of 1, 2, 1, and 2. Therefore, it is possible to obtain an elastic narrow knitted fabric that does not bend even when the ribbon-like stretch recovery is similar to that of stretchable warp knitted fabrics in the field of women's underwear materials and sports clothing. be able to.

Further, by partially entwining the elastic yarns 22, 22 for the ear hooking yarn with the pulling yarn 31 once every 3 to 5 courses, the pulling yarn 31 can be easily removed and removed. When the drawn yarn 31 is removed, the elastic yarn 22 entangled in the drawn yarn 31 can be contracted to form smooth ears, and as a stretchable warp knitted fabric accessory that serves as a base fabric. It is a beautiful tape-like warp knitted fabric for stretchable width that does not bend even when the tape is stretched and recovered, because it does not require fraying and does not cause fraying.

Further, the dyeing surface can be subjected to the same dyeing processing as the wide stretchable warp knitted fabric for the body cloth, and therefore the wide stretchable body cloth can be stretched in terms of dimensional stability, hue stability and the like. It is possible to obtain the same physical properties as the warp knitted fabric.
