[Prior art]
2. Description of the Related Art Conventionally, various elastic fabrics are known for garments such as foundations, sports clothing, and outer garments that require excellent elastic force depending on their usage. As these elastic fabrics, warp knitted fabrics are known in which the ground texture is knitted with synthetic fiber multifilaments or cotton yarn, etc., and a single or plural (more specifically, one type or two or more types) elastic yarns are combined. JP-A-52-37873, JP-A-5-339855, JP-A-5-33170, JP-A-7-54312).
Alternatively, there is known a warp knitted fabric in which knitted fabric pieces having different knitted structures are juxtaposed in the course direction and using a plurality of types of elastic yarns to impart elastic force (Japanese Patent Laid-Open No. 7-300749, actual application). Sho 63-11196).
[0003]
These warp knitted fabrics are knitted by a warp knitting machine such as a tricot knitting machine or a Russell knitting machine. The warp width of the warp knitting machine is 1 m or more, and the warp knitted fabric is usually knitted using the full length of the warp width. Therefore, when making a garment such as a foundation from a warp knitted fabric, a plurality of warp knitted fabric pieces designed according to the shape of the target garment is cut from a warp knitted fabric having a width of 1 m or more, and the plurality of warp knitted fabrics are cut. A garment product is obtained by sewing the knitted fabric pieces. However, if the hem part of the garment is cut only, the yarn protrudes from the cut part or loosens. Therefore, it is often performed to prevent loosening such as folding the end of the warp knitted fabric piece and sewing. Is called. However, when such a loosening prevention treatment is used, the hem portion of the clothes becomes thick, which causes a problem that the feeling of wearing and the external appearance deteriorate.
[0004]
Therefore, knitting is performed so that the portion of the knitted fabric piece that becomes the hem portion of the clothing becomes the ear portion of the warp knitted fabric. However, since the garment length is 50 cm at the maximum in the case of a foundation or the like, knitting with a warp knitting machine having a heel width of 1 m or more is extremely inefficient, resulting in high cost of garment products.
In order to solve this problem, knitting a wide warp knitted fabric by connecting two warp knitted fabrics having ends corresponding to the ears along the wale direction at the pulling yarn structure, It is known to prepare a warp knitted fabric having a width corresponding to the required width of a plurality of clothes products by removing a thread after preparing a necessary warp knitted fabric by dyeing and finishing. . It is preferable to provide n pieces of such a yarn removal structure, since n + 1 warp knitted fabrics are knitted simultaneously, so that the knitting of the warp knitted fabric can be efficiently performed and the cost can be reduced.
[0005]
[Problems to be solved by the invention]
However, the conventionally known punched yarn structure has various limitations because it assumes a knitted structure that can easily perform a specific function of the drawn yarn. That is, in order to allow the drawn yarn to be pulled out from the loops of the respective yarns extending from the warp knitted fabrics on both sides and entangled with the drawn yarn, the stitch structure of the drawn yarn itself is limited to the comb knitting. Next, the yarn extending from the warp knitted fabric on both sides in order to get entangled with the drawn yarn needs to be arranged in the insertion type, that is, the type that is not knitted, in the stitches of the drawn yarn. In other words, if the yarn extending from the warp knitted fabric on both sides is knit on the cut-out yarn, the yarn extending from the warp knitted fabric on both sides is knit even if the cut-off yarn itself can be loosened and removed from the warp knitting. Since the thread is bundled, the thread cannot be removed from the structure.
Further, since the yarn extending from the warp knitted fabric on both sides entangled with the drawn yarn needs to be removed after the drawn yarn is removed, elastic yarn is used as these yarns.
Therefore, in a warp knitted fabric having a conventionally known draw-off yarn structure, the elastic yarn is limited to the stitch structure of the elastic yarn entangled with the draw-off yarn of the draw-off yarn structure, that is, the insertion type, so that it can be inserted into the main part of the warp knitted fabric. It becomes a model. Therefore, the elastic force in the warp knitted fabric body can be increased, but at the same time, there is a problem that a heavy warp knitted fabric is formed.
Recently, there is a demand for a soft feel and light weight in clothing products. When a warp knitted fabric is knitted by providing a drawn yarn structure, a light and soft warp knitted fabric cannot be obtained due to the above-described circumstances. Accordingly, an object of the present invention is to provide a connected knitting mechanism in which a warp knitted fabric body is light and soft with elasticity and can be connected with a pulling thread that can remove a desired warp knitted fabric. To do.
[0006]
[Means for Solving the Problems]
The above-mentioned object of the present invention is to provide elastic warp knitted fabrics B, C comprising two or more elastic yarns on both sides of a one-wale drawn yarn structure A comprising at least one non-elastic yarn comb knitting. Is a separable connecting knitting mechanism of adjacent elastic warp knitted fabrics, wherein elastic warp knitted fabrics B and C are swung left and right, while inelastic yarns knit on all courses and swung left and right. A first elastic yarn that is arranged by alternately repeating knit and insertion for each course, and a second elastic yarn that is arranged by repeating knit and insertion alternately with the first elastic yarn while being swung left and right. The first elastic yarn and the second elastic yarn are alternately inserted in the direction of the wale in the cut-out knitting of the cut yarn structure portion A by connecting the drawn yarn structure portion A and the elastic warp knitted fabric on both sides. In this case, the knitted fabric is knitted and arranged in the drawn yarn structure part A. Consisting achieved by each of the one wale of the first elastic yarn and the elastic warp knitted fabric of splittable linking knitting mechanism, characterized in that to keep the second elastic yarn is removed.

[0016]
In the composite elastic warp knitted fabric shown in FIG. 1, the elastic warp knitted fabric B and the elastic warp knitted fabric C are knitted with the same knitting structure. However, it differs depending on the connection relationship with the drawn yarn structure portion A. First, in the case of the non-elastic yarn 5 of the elastic warp knitted fabric B, the non-elastic yarn 5 is supplied to the knitting needle from the right side of the wale (3) in the course (1) by the heel L-1 and knit to the right side by 2 wales. Swing and knit with the knitting needle of the wale (5) in the course (2), and then sway to the left by 2 wales, knit with the knitting needle of the wale (3) in the course (3), repeat this knitting and repeat the course (8 ) Knit with the knitting needle of wale (5). The non-elastic yarn 6 of the elastic warp knitted fabric C is knitted in the same manner as the non-elastic yarn 5, but, as is apparent from FIG. 1, is knitted or inserted into the knitting needle of the wale (6) of the drawn yarn structure portion A. There is no inelastic yarn.
In the case of the first elastic yarn 16 of the elastic warp knitted fabric C, the first elastic yarn 16 is supplied to the knitting needle from the left side of the wale (7) in the course (1) by the heel L-4 and knits, and 1 left side of the wale.

The first elastic yarn 15 of the elastic warp knitted fabric B is also knitted in the same manner, but as is apparent from FIG. 1, it is not related to the knitting needle of the wale (6) of the drawn yarn structure portion A.
In the case of the second elastic yarn 36 of the elastic warp knitted fabric B, the second elastic yarn 36 is inserted from the right side into the knitting needle of the wale (6) of the drawn yarn structure portion A in the course (1) by the heel L-3. It is swung to the left of 1 wale and knit with the knitting needle of the wale (5) in the course (2), and then swung to the right of 1 wale and inserted into the knitting needle of the wale (6) in the course (3). This knitting is repeated to knit the knitting needle of the wale (5) in the course (8). The second elastic yarn 37 of the elastic warp knitted fabric C is knitted in the same manner, but as is apparent from FIG. 1, it is not related to the knitting needle of the wale (6) of the drawn yarn structure portion A.
[0017]
As shown in FIG. 1, the drawn yarn 70 of the drawn yarn structure portion A is supplied from the left side to the knitting needle of the course (6) by the heel L-2 and continues the knitting in the cut knitting.
In the composite elastic warp knitted fabric of Example 1, as is apparent from the threading diagram of FIG. 1, the supply of the non-elastic yarn performed at the heel L-1 is not performed at the wales 4, 5 and 6, and at the same time at the heel L-4. The supply of the first elastic yarn that is performed is not performed in the wale 6, and the second elastic yarn that is performed in the heel L-3 is not performed in the wale 7. Accordingly, the yarn related to the knitting needle 70 of the weave knitting and the knitting needle of the wale (6) extends from the left elastic warp knitted fabric B every course and the right elastic warp knitted fabric C. Only the second elastic thread 36 extending from the second elastic thread 36 is inserted.
Therefore, as shown in FIG. 2, when the take-off yarn 70 is removed, the first elastic yarn 16 returns along the ear of the right elastic warp knitted fabric C by its elastic force, and the second elastic yarn 36 also has its elasticity. By force, the elastic warp knitted fabric B returns to the left elastic warp knitted fabric B so that two elastic warp knitted fabrics B and C having a clean ear are obtained.
