[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-layer warp knitted fabric knitted by a double needle row warp knitting machine with a jacquard device.

[0002]

2. Description of the Related Art Conventionally, using a double needle row warp knitting machine,
While forming the front and back base cloth by the front and rear needle rows, respectively,
Knit a two-sided warp knitted fabric by reciprocating the connecting yarn between the base fabrics,
The three-layer warp knitted fabric is widely used in the field of industrial materials and clothing. These can be broadly classified into two structures, one of which is a plain knitted fabric for both front and rear base fabrics, and the other of which is a mesh knitted fabric for at least one side.

[0003]

However, in each of the above-mentioned methods, water absorption, moisture absorption, air permeability, high elasticity, etc. are obtained by using yarn types, but only functionality is pursued. However, the appearance was poor in decorativeness, and thus, the use was limited to a limited field.

[0004] The present inventor has made intensive studies to further develop the above based on the public technical report 87-3897, which discloses the basic technical concept of the above-mentioned three-layer warp knitted fabric. It is intended to provide a warp knitted fabric having a three-layer structure that retains its properties and has an excellent decorative effect.

[0005]

SUMMARY OF THE INVENTION A three-layer warp knitted fabric according to the present invention is knitted by a double needle row warp knitting machine comprising front and rear base fabrics and connecting yarns for providing a gap between the base fabrics. In the flat warp knitted fabric, each wale constituting at least one side of the base fabric is constituted as a changed structure individually controlled by jacquard control. Further, the modified structure is characterized in that it has decorative appearance, and the wale of the base fabric on one side having no changed structure is independent of each other in the weft direction, while the wale of the base fabric on the other side is independent. It is characterized by having a wavy frilled form under the influence of the connecting yarn connected to the changing structure.

FIG. 2 is a schematic side view of a main part of a knitting needle of a double needle row warp knitting machine for knitting a three-layer warp knitted fabric according to the present invention. B is a knitting needle for forming a rear needle row. 1,2,3,
4 and 5 are yarn guides, in which the yarn guide 2 is
The position of the tip in the guide frame 6 can be displaced in the needle row direction by a jacquard device (not shown).
Numerals 11, 12, 13, 14, and 15 are knitting yarns passed through the respective yarn guides.

FIG. 1 is a knitting structure diagram showing an embodiment of a three-layer warp knitted fabric of the present invention, wherein F is a course of a front knitting needle row, B is a course of a rear knitting needle, and The points in the figure indicate the positions of the respective knitting needles, but for clarity, the points after the substantially middle half are omitted from the B side. The knitting yarn 11 and the knitting yarn 12 knit a front base fabric, and the knitting yarn 14 and the knitting yarn 15 knit a back base fabric. The knitting yarn 13 is a connecting yarn formed by reciprocating and knitting in order to provide a space between the front and rear base fabrics. The knitting yarns 12 are individually controlled by the jacquard control as described above, and each knitting yarn, like the knitting yarns 12-1 to 12-7, acts between adjacent knitting needles in each knitting course. 20 and Jacquard controlled chain wale 21
Is appropriately present in the base fabric. _{M 1, M 2 ... M 9} ... is a hole that occurs in the base fabric by interaction of the throttle restriction 20 and chain wale location 21.

FIGS. 3 and 4 show an embodiment of a three-layer warp knitted fabric. In FIG. 3, reference numeral 25 denotes a front base cloth having holes M ₁ , M _2, ... Of various sizes. Reference numeral 30 denotes a rear base cloth, which forms a flat knit base cloth by the knitting yarns 14 and 15 of the chain knitting and the insertion knitting, and is used for providing a gap between the base cloth 25 and the base cloth 30. A knitting yarn 13 as a connecting yarn is interposed.

For example, as shown in FIG. 5, the three-layer structure shown in FIG. 3 can be used as a cloth for athletic shoes or the like so that the three-layer structure has an impact on the foot during use. And the mesh is irregularly arranged by the jacquard, so even if a repeated load is applied, the load is dispersed and absorbed, so no concentrated stress is generated. The sag as seen in the fabric is less likely to occur, and the durability is improved.

In a three-layer warp knitted fabric as shown in FIG. 4, the front side base cloth 25a has a large hole M in the base cloth 25a.
₁ and forming a pattern combining a small hole portion M _2, the rear base fabric 30a so as to form a breathable hole ground structure, the knitting yarn 1 as a connecting yarn between the two base fabrics 25a, 30a
3 are arranged in a reciprocating manner.

By using such a form as shown in FIG. 4 as, for example, a bed covering cloth as shown in FIG. 6, the weight of the body is dispersed throughout the body, and bed slips, which are particularly likely to occur to bedridden elderly people, are also reduced. As the whole body fits and the load is dispersed, it is less likely to occur, and since it has a decorative effect compared to conventional plain ones, it has a mental space, and because it has good ventilation, it can be peeled off to the whole body It is always sanitary because it is easy to dry 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 insertion knitting for connecting the chain knitting by the knitting yarn 14 is removed from the beginning. As a result, the front side base fabric has a fold 50 formed in the knitting direction by the knitting yarn 14 and the knitting yarn 13, and the fold 50 is connected to the knitting row of the hole structure of the front side base fabric. Therefore, a meandering fold corresponding to the curve of the hole is formed. This can be used as a frill to be sewn to a part of clothes, for example, by turning the knitting direction sideways as shown in FIG.

In the present application, in addition to the above-described embodiments, the combination of the pattern structure can be considered by selecting the structure of the rear base fabric and the Jacquard effect of the front base fabric. Needless to say, land is obtained.

[0014]

[Effect of the Invention] The three-layer warp knitted fabric according to the present invention has an effect as an original three-dimensional structure and a jacquard change structure on one side by a connecting yarn providing a gap between the front base fabric and the rear base fabric. The use of three-layer warp knitted fabric has been expanded by the combination of the base fabrics.
