  The present invention is a warp knitted fabric including a chain knitting yarn, a warp insertion yarn, and a jacquard yarn. There are Raschel, tricot, etc. in the warp knitted fabric, and any can be applied as long as the jacquard machine has a number of folds. In the present invention, an example applied to a Raschel warp knitted fabric will be described.

  The chain knitting yarn knitting a ground structure by chain knitting, and the jacquard yarn knitting a jacquard structure. The chain stitch is included to maintain the quality of the fabric. In such a knitted fabric, most of the warp insertion yarn appears on the surface without being knitted into the fabric, and has a portion that is partially knitted in the knitted fabric and cannot be seen on the surface. The pattern is organized. Here, the majority of the warp insertion yarn refers to 90% or more, and the partial refers to less than 10%. That is, most of the warp insertion yarn appears on the surface and contributes to the knitted pattern (knitted pattern).

  As an example, chain knitting yarn, warp insertion yarn, and jacquard yarn are each 2 courses, a total of 6 courses, making a single repeat, and 4 courses of warp insertion yarn and jacquard yarn are not knitted. Two courses of yarn are knitted with chain stitches. Repeat is the smallest unit of knitting structure. This knitting structure is repeated to form a wide knitted fabric. In the case of one repeat of the 6 courses, 4 courses are not knitted and 2 courses are knitted (chain knit), so about 68% appears on the surface of the knitted fabric. As another example, one course chain knitting is possible with eight courses. As another example, 1 course stitches with 6 course repeats, 1 course stitches with 3 courses, etc. are possible. Repeat courses of 2 to 12 are sufficient, and more than that are possible. Any number of chain knitting and stitch knitting can be combined as long as it is 1 or more. It is also possible not to make stitches.

  The chain knitting is arranged at yarn numbers 1 and 6 to knit the ground knitting structure by chain knitting, the warp insertion yarn is arranged at yarn numbers 2 and 5 and the pattern is knitted, and the jacquard yarn is yarn numbers 3 and 4 It is preferable to arrange them in a jacquard organization. For the warp insertion yarn for knitting the knitted pattern (knitted pattern), a yarn having a different color from the chain knitting yarn and the jacquard yarn (different color yarn) is used. The pattern can be made clearer by using the different colored yarn. The different color yarn can be realized by, for example, original dyeing yarn, yarn dyed before knitting (cotton dyeing yarn, yarn dyeing yarn, etc.), and dyeing by post-dying (use of acid dye, disperse dye, cationic dye).

  As the jacquard yarn, it is preferable to use a covering yarn in which a synthetic fiber filament yarn is wound around a core elastic filament yarn as a sheath. Thereby, stretchability (stretchability) can be provided.

  The method of the present invention is a warp knitted fabric including a chain knitting yarn, a warp insertion yarn, and a jacquard yarn knitted using at least six heels including a jacquard heel. Knit numbers 1 and 6 are knitted to form a knitted fabric with chain stitches, knot numbers 2 and 5 are arranged with warp insertion yarns to knitting patterns, The jacquard structure is knitted by arranging the jacquard yarn passed through. As a result, most of the warp insertion yarn appears on the surface without being knitted into the fabric, and part of the warp insertion yarn that appears on the surface is partially knitted in the knitted fabric. A warp knitted fabric. In the case of double raschel, a pattern appears on the inner side, so that it is necessary to use a tubular knitting, and a pattern with warp insertion yarn is knitted on the inner side. In the case of a non-double Russell, the pattern is knitted on the front side.

  This will be described below with reference to the drawings. In the following drawings, the same reference sign means the same thing. FIG. 1 is a schematic side view showing a main part of a double raschel knitting machine used for manufacturing a warp knitted fabric in one embodiment of the present invention. This knitting machine is a double raschel machine having two rows of needles in the front and rear and a jacquard rod whose lateral movement is controlled by a jacquard device. F is a front needle row, B is a rear needle row, and ridges L1 to L6 are arranged from the front side to the rear side of the knitting machine with respect to the needle rows F and B. Among these, L1, L2, L5, and L6 indicate grounds for knitting a chain structure or insertion tissue in the ground tissue, and L3 and L4 indicate jacquard saddles. The chain knitting yarns 1 and 6 knit the ground knitting structure by chain knitting through the ridges L1 and L6, respectively. The warp insertion yarns 2 and 5 knit the pattern through the ridges L2 and L5. The jacquard yarns 3 and 4 form a jacquard structure through jacquard ridges L3 and L4. The warp knitted fabric 7 is knitted with the front needle row F with the heels L1 to L3, and the same warp knitted fabric 8 is knitted with the rear needle row B with the heels L4 to L6. At this time, among the collars L1, L2, L5, and L6 for knitting the ground structure, the structure of L2 and L5 is not inserted so that the structure of the knitted fabric passes through the structure of L3 and L4. I try to come out. By doing so, the transinserted yarn is concealed conversely due to the structural change of the jacquard.

  FIG. 2 is an organization chart of a warp knitted fabric in one embodiment of the present invention. Place chain knitting yarns on heel numbers 1 (GB1) and 6 (GB6) to knitting a ground knitting structure with chain knitting, and place warp insertion yarns on heel numbers 2 (GB2) and 5 (GB5) to create a pattern. Knit and arrange the jacquard structure by placing the jacquard yarns passed through the jacquard ridges on ridge numbers 3 (GB3) and 4 (GB4).

  FIG. 3 is an organization chart of a warp knitted fabric according to another embodiment. What is different from FIG. 2 is that the thread No. 2 (GB2) and 5 (GB5) warp insertion yarns are looped in several places. By doing in this way, the surface yarn can be prevented from coming off from the time of knitting. For example, even if it is scratched with a nail, it can be hard to come off. However, there is a problem that the expression of the pattern is slightly lowered. FIG. 4 is an organization chart of a warp knitted fabric in still another embodiment. The difference from Fig. 2 is that arrows are added to the jacquard organization at numbers 3 (GB3) and 4 (GB4). By doing in this way, the warp insertion yarns of the hook numbers 2 and 5 do not appear on the surface of the fabric, but are held by the jacquard structure and the chain stitch. That is, it is sandwiched between a chain knitting yarn and a jacquard knitting yarn. As a result, the fabric becomes thick due to the change in the jacquard structure, and becomes convex.

  FIG. 5 is an organization chart of a warp knitted fabric in still another embodiment. The difference from Fig. 2 is that arrows are added to the jacquard organization at numbers 3 (GB3) and 4 (GB4). By doing in this way, the warp insertion yarns of the hook numbers 2 and 5 do not appear on the surface of the fabric, but are pressed by the jacquard structure and the chain stitch. Moreover, it will be in the state which makes a hole in cloth by the change of a jacquard structure. In the case of a raschel knitted fabric, the jacquard texture can usually be changed from a thin fabric to a thick fabric or from a hole.

  FIG. 6 is a schematic explanatory view of a warp knitted fabric in one embodiment of the present invention, and shows an actual state of yarn and fabric. FIG. 7 is a schematic explanatory view of a warp knitted fabric according to another embodiment, and is an organization chart showing the movement of the yarn.

  In the above description, the formation of the knitted pattern (knitted pattern) has been described. However, in addition to the knitted pattern (knitted pattern), a pile (napped) can be formed. This can be achieved by the insertion yarn that appears on the surface of the fabric without being knitted in the shape of a pile. Since the pile can be partially taken out, for example, when the pile is put out only in the abdomen, a warm warp knitted fabric of the abdomen can be created.

  Hereinafter, more specific description will be made using examples. In addition, this invention is not limited to the following Example.
