[Industrial applications]

 The present invention relates to a three-layer structure warp knitted fabric knitted by a double needle row warp knitting machine with a jacquard device.

[0002]

[Prior Art]

 Conventionally, a double needle row warp knitting machine is used to form front and rear base fabrics by front and rear needle rows, respectively, and a connecting yarn is reciprocated between the base fabrics to knit a two-sided warp knitted fabric. The three-layer structure warp knitted fabric is widely used in the fields of industrial materials and clothing. These are roughly divided into two structures, one is a plain knit for both front and back base fabrics, and the other is a mesh knit for at least one side base fabric. ..

[0003]

[Problems to be solved by the device]

 However, in all of the above, although it is obtained by a yarn type that uses water absorption, moisture absorption, breathability, high elasticity, etc., only functionality is pursued and appearance is decorative. It was scarce and for this reason it remained in fields with limited applications.

The inventor of the present invention has made extensive studies to further develop it based on the open technical report 87-3897, which discloses the basic technical idea of the above-mentioned three-layer structure warp knitted fabric. It is intended to provide a three-layer structure warp knitted fabric that retains functionality and is excellent in decorative effect.

[0005]

[Means for Solving the Problems]

 The three-layer structure warp knitted fabric according to the present invention is a two-sided warp knitted fabric knitted by a double needle row warp knitting machine consisting of front and rear base fabrics and connecting yarns for forming gaps between the base fabrics. Each wale that constitutes the base fabric on the side is configured as a change organization that is individually controlled by jacquard control. In addition, the change structure has a decorative appearance, and the wales of the base fabric on one side that do not have the change structure are independent of each other in the weft direction and are independent of each other. It is characterized in that it has a wavy frill shape under the influence of the connecting thread connected to the altered tissue.

【Example】

 FIG. 2 is a schematic side view of a knitting main part of a double needle row warp knitting machine for knitting a three-layer structure warp knitted fabric of the present invention, where F is a knitting needle forming a front needle row, and B is a rear side. Is a knitting needle for forming the needle row of. 1, 2, 3, 4, 5 are yarn guides, in which the yarn guide 2 displaces the tip position in the needle row direction in the guide frame 6 by a jacquard device (not shown). It is possible. Reference numerals 11, 12, 13, 14, and 15 are knitting yarns that are threaded through the respective yarn guides.

FIG. 1 is a knitting structure diagram showing an example of a three-layer structure warp knitted fabric of the present invention, where F is a course of a front knitting needle row, B is a course of a rear knitting needle, and The dots in the figure indicate the positions of the respective knitting needles, but for the sake of clarity, the dots on the B-side are omitted for the sake of clarity. The front base fabric is knitted by the knitting yarns 11 and 12, and the rear base fabric is knitted by the knitting yarns 14 and 15. The knitting yarn 13 is a connecting yarn that is reciprocally knitted to provide a space between the front and rear base fabrics. As described above, the knitting yarns 12 are individually controlled by the jacquard control. Like the knitting yarns 12-1 to 12-7, each knitting yarn acts on each knitting course between adjacent knitting needles. A squeezing point 20 and a jacquard-controlled chain wheel point 21 are optionally present in the backing. M ₁ , M ₂ ... M ₉ ... Are holes formed in the base cloth by the interaction between the drawing portion 20 and the chain wale portion.

3 and 4 show an example of a three-layer structure warp knitted fabric. In FIG. 3, reference numeral 25 is a front side base cloth, which has holes M ₁ , M ₂ ... Of various sizes. Reference numeral 30 denotes a back side base cloth, which forms a plain knit base cloth by the knitting yarns 14 and 15 of the chain knitting and the insertion knitting, and provides a space between the base cloth 25 and the base cloth 30. A knitting yarn 13 as a connecting yarn is interposed.

[0009] In the case of the form as shown in Fig. 3, for example, as shown in Fig. 5, by using it as a cloth for covering such as athletic shoes, the three-layer structure has the original function of impact on the foot during use. Since the mesh is irregularly arranged by jacquard, the load is dispersed and absorbed even if repeated load is applied, so concentrated stress does not occur. The slack that is seen in conventional fabrics is less likely to occur and durability is improved.

In the three-layer structure warp knitted fabric as shown in FIG. 4, the front side base cloth 25a has a pattern in which a large hole portion M ₁ and a small hole portion M ₂ are formed in the base cloth 25a. The rear side base cloth 30a is formed as a hole ground structure having good air permeability, and the knitting yarn 13 as a connecting yarn is reciprocally arranged between both base cloths 25a and 30a.

By using such a form as shown in FIG. 4 as the cloth for the bed cover shown in FIG. 6, for example, the weight of the body is dispersed over the whole body, and especially the bed sore which is likely to occur in the bedridden elderly person, It is less likely to occur because the whole body fits and the load is distributed, and it has a decorative effect compared to the conventional plain ones, which creates mental comfort and further breathes, so it is distorted throughout the body. Always, it is hygienic because it does not dry out even after washing.

FIG. 7 shows another embodiment of the present invention. In the knitting structure shown in FIG. 1, the knitting yarn 15 of the insert knitting for connecting the chain knitting by the knitting yarn 14 is removed from the beginning. Therefore, the front side base cloth is formed with the folds 50 in the knitting direction by the knitting yarns 14 and 13, and the folds 50 are connected to the knitting row of the hole structure of the front side base fabric. Therefore, it becomes a meandering fold corresponding to the curve of this hole. This can be used as a frill which is sewn to a part of clothes, for example, with the knitting direction set sideways as shown in FIG.

In addition to the embodiments described above, the present application contemplates a combination of pattern designs due to the selection of the structure of the back side base fabric and the Jacard effect of the front side base fabric, and various novel three-layer structure It goes without saying that a knitted fabric can be obtained.

[0014]

[Effect of the device]

 The three-layer structure warp knitted fabric according to the present invention has an effect as an original three-dimensional structure by a connecting yarn that provides a gap between the front side back cloth and the back side back cloth, and a combination of the back cloth by the jacquard change structure on one side. The applications of the three-layer structure warp knitted fabric have been expanded.
