Description

  The present invention relates to a warp knitted fabric such as a raschel fabric or a tricot fabric, and more particularly to a mesh warp knitted fabric that is thin and delicate and has a high mesh density.

Mesh warp knitted fabrics are frequently used for women's inner garments such as lingerie and foundation, and stockings.
This is due to the good breathability by having thin eyes and the fact that it is fashionable, delicate and comfortable.
And many technical means are developed and provided as a method of manufacturing this mesh warp knitted fabric (refer patent document 1).

As its basic means, there is a mesh warp knitted fabric as shown in the organization chart of FIG.
This is organized using two pieces.
The knitting yarns Y1, Y1, Y1,..., Y2, Y2, Y2,.
That is, the mesh warp knitted fabric is knitted by passing the yarn through two ridges by a yarn removing method that passes the yarn in 1 in 1 out.
In this knitting by the thread removal method, the mesh density and the size of the mesh can be adjusted depending on the structure, but there is a limit to making the knitted fabric portion thinner.
That is, in the yarn removing method, there is a problem that the knitted fabric portion is formed by the knitting yarn Y1 and the knitting yarn Y2 to form the two wells W1 and W2, and the knitted fabric portion does not become thinner.

On the other hand, there is also a mesh knitting means in which the knitted fabric portion is the smallest 1 wale W.
The most basic one is the tulle structure C shown in FIG.
This tulle structure is knitted into a mesh warp knitted fabric by passing all the yarns through a guide of one piece.
The tulle structure has a hexagon-shaped turtle shell-shaped anamorphic H. However, the length and angle of each side of the hexagon are not equal at the stage of knitting, and the turtle-shaped anamorphic H is accurate. There is a problem that does not become.
In particular, the sinker loop S formed when moving from the wafer W to the wafer W is in a single knitting yarn, and a uniform turtle shell type hole H cannot be obtained in terms of strength and balance. .
In order to correct this, the insertion yarn L is used to make the location of one sinker loop into two knitting yarns (SL part), and the balance is obtained to obtain a hexagonal shape as accurate as possible, and the strength is also obtained (Fig. In Fig. 3, only one insertion thread L is shown in order to avoid complication of the figure, but it is actually inserted into all wales).
In this tulle structure C, the knitted fabric part is composed of one waist and has the smallest fineness, but the mesh is a hexagon with a tortoiseshell type mesh H, which is more geometric than a square or triangular mesh. It's not the smallest.

As described above, it has been difficult to obtain a mesh warp knitted fabric having a thinner thickness, a higher mesh density, and an accurate small mesh with conventional manufacturing means.
JP-A-7-70893

In the field of mesh warp knitted fabrics used for these women's inner garments etc., further thinness, high mesh density, as small as possible, etc. are required, and the improvement of the delicateness, fashionability and comfort is required. Expected.
However, as described above, with the conventionally known means, there is a problem that it is not possible to obtain a satisfactory mesh warp knitted fabric having characteristics such as thinner, higher mesh density, and smaller texture. .
The present invention has been made based on such a technical background.
That is, an object of the present invention is to provide a mesh warp knitted fabric that is thinner than a conventional tulle structure formed by one piece of cloth, has a high mesh density, and has a uniform and accurate small mesh.

In order to solve these problems, in the present invention, the desired mesh warp knitted fabric T was obtained by skillfully combining the front structure F and the back structure B formed using two ridges.
That is, as shown in FIG. 1A, two sides formed by two back needle loops NB and NB, a back sinker loop BS and a front sinker loop FS are entangled in a cross shape. A rhomboid mesh DH formed by a total of four sides including two crossed sinker loops HS and HS is formed.
The four sides are connected to each other by a front needle loop NF that is knitted to be smaller than the back needle loop NB.

That is, the present invention is (1) a mesh warp knitted fabric T formed by repeatedly forming a rhomboid mesh DH, and the rhomboid mesh DH is formed by two back needle loops NB and NB. And four sides of two crossed sinker loops HS, HS formed by crossing back sinker loop BS and front sinker loop FS in a crossed manner, and at the same time The front needle loops NF, NF, NF, NF, which are knitted to a minimum compared with the back needle loops NB, NB, are interposed at the connecting points of these four sides (NB, NB, HS, HS). It exists in the mesh warp knitted fabric T connecting the four sides.

  And (2), with front organization F (1-0 / 1-1 / 1-2 / 1-1) and back organization B (0-0 / 0-1 / 2-2 / 2-1) The mesh warp knitted fabric T is configured such that the front needle loop NF and the back needle loop NB are alternately formed in the direction of the wale W, and the front needle loop NF and the back needle loop NB are Are connected by a front sinker loop FS and a back sinker loop BS, respectively, and the front sinker loop FS and the back sinker loop BS are entangled in a cross shape to form a cross sinker loop HS. At the same time, the back needle loop NB is knitted to approximately the same length as the crossed sinker loop HS, and the front needle loop NF is back need. By being knitted to a minimum as compared with the loop NB, a rhombus mesh DH comprising four sides of two back needle loops NB, NB and two crossed sinker loops HS, HS is formed. It exists in the mesh warp knitted fabric T.

  (3) The mesh warp knitted fabric T according to (1) and (2) above, wherein the mesh warp knitted fabric T is formed of a covered yarn obtained by covering a polyurethane yarn with a synthetic fiber wooly yarn. Exist.

  And (4), the mesh warp knitted fabric T exists in the mesh warp knitted fabric T of the said (1), (2) description formed with the synthetic fiber wooly yarn.

  And (5), the mesh warp knitted fabric T exists in the mesh warp knitted fabric T as described in said (1) and (2) currently formed with the synthetic fiber raw yarn.

And (6), the basis weight of the mesh warp knitted fabric T exists in the mesh warp knitted fabric T described in the above (1) and (2), which is in the range of 40 gram / m ^{2 to} 100 gram / m ² .

In addition, as long as the objective of this invention is followed, the structure which combined said (1) to (6) suitably is also employable.

Since the mesh warp knitted fabric T of the present invention is formed with a rhombus mesh DH composed of four sides (NB, NB, HS, HS), it is compared with the turtle shell pattern mesh H composed of the six sides of the conventional tulle structure C. As a result, the mesh becomes small and the mesh density can be increased.
In addition, although two pieces of cloth are used, it is possible to form a knitted fabric part with one wale compared to the conventional thread removal method, and it is possible to form a thin, delicate and extremely light mesh warp knitted fabric. became.
For these reasons, it has become possible to provide a fashionable and comfortable mesh warp knitted fabric T used for women's innerwear.

Furthermore, since this mesh warp knitted fabric T is securely connected by the four front needle loops NF at the four sides forming the rhomboid mesh DH, no misalignment occurs and under any use conditions However, an accurate parallelogram is maintained.
Therefore, this mesh warp knitted fabric T can be used not only for clothing but also as industrial material.
For example, insect repellent nets used in pesticide-free cultivation require small meshes and high-density meshes to prevent the entry of extremely small insects, and woven meshes have conventionally been used.
This mesh warp knitted fabric T not only fully functions as a mesh fabric that replaces the woven mesh, but also is superior to the woven fabric in terms of production efficiency.

  A mesh warp knitted fabric T with high mesh density, thin and delicate, and without misalignment, by making the shape of the eye into a rhombus consisting of four sides and securely connecting these four sides with four front needle loops NF Form.

Embodiment 1
In the present embodiment, the mesh warp knitted fabric T is knitted using two pieces of cloth, a front cloth and a back cloth.
That is, as shown in the organization chart of FIG. 1 (B), the mesh warp knitted fabric T is a front fabric, and the front fabric F (1-0 / 1-1 / 1-2 / 1-1) is replaced with a back fabric. Thus, it is formed by knitting the back tissue B (0-0 / 0-1 / 2-2 / 2-1).
As shown in FIG. 1 (C), the basic organization of this organization is the denby organization (1-0 / 1-2) of the closing as shown in FIG. 1 (C), and the back organization B in FIG. 1 (D). As shown in FIG. 4, it is a denby structure (0-1 / 2-1) of the opening.

In the case of the front structure F, every other blind wrap part (1-1) that does not make a stitch is sandwiched between the basic denby structure (1-0 / 1-2) of the basic structure, and the front structure F ( 1-0 / 1-1-1-1-2 / 1-1).
In the case of the back structure B, the blind wrap portions (0-0 and 2-2) are sandwiched between the denby structure (0-1 / 2-1) of the opening which is the basic structure, and the back structure B (0-0) / 0-1 / 2-2 / 2-1).
Thus, the mesh warp knitted fabric T which is not in the past was obtained by combining and knitting the structure obtained by combining the denby structure and the blind wrap portion with two ridges.

  According to this organization, as shown in the organization chart of FIG. 1 (B), the front needle loop NF of the front tissue F and the back needle loop NB of the back tissue B are sequentially arranged in each of the wells W. Since the knitted fabric is repeatedly knitted and the front needle loop NF and the back needle loop NB are not knitted to overlap, a thin knitted fabric can be obtained.

  In FIG. 1A, the front needle loop NF is connected by a front sinker loop FS. The back needle loop NB is connected to the back sinker loop NB1. BS1 does not directly reach the next back needle loop NB2, but temporarily passes under the front sinker loop FS1 and further passes over the back needle loop NB3 to reach the back needle loop NB2. Therefore, the back sinker loop BS1 crosses the front sinker loop FS1 and becomes in a state of being entangled with the front sinker loop FS1.

This entangled state can be realized for the first time in the mesh structure of the present invention.
In other words, this is made possible by the presence of the blind wrap portions (0-0 and 2-2) in the back tissue B (0-0 / 0-1 / 2-2 / 2-1), which is shown in FIG. The structure (SL part) is similar to the relationship between the sinker loop S and the insertion yarn L in the tulle structure C, and an effect equal to or higher than that can be obtained.
As shown in FIG. 1A, when the back sinker loop BS and the front sinker loop FS are entangled in an intersecting manner, a crossed sinker loop HS in which two sinker loops are combined into one. As a result, a stable and clean mesh is obtained.

In such a tissue configuration, the front needle loop NF is knitted as small as possible with respect to the back needle loop NB.
As a result, the presence of the front needle loop NF does not obstruct the viewing angle. As shown in FIG. 1A, the back needle loop NB, NB has two sides, and the crossed sinker loop HS, A rhomboid mesh having an appearance that is formed with only a total of four sides of HS is formed.
The front needle loop NF knitted to a minimum serves to connect the four sides with certainty.
The rhomboid mesh DH is actually formed by two sides obtained by two back needle loops NB and NB, and two sides formed by two crossing situation sinker loops HS and HS, The four front needle loops NF connecting the two are used.

  In the above description, the needle loop refers to a portion that is knitted to form a loop, and the sinker loop refers to a portion that merely communicates between the needle loops but does not form a loop (in this specification, blind Including the lap part).

As described above, the warp knitted fabric of the present invention has a specific function, but the function is further enhanced by the knitting yarn used.
That is, as the knitting yarn used for the warp knitted fabric of the present invention, a cover yarn obtained by winding another yarn around a core yarn is employed.
The thickness of the core yarn is preferably in the range of 10 dtex to 25 dtex from the viewpoint of supporting the winding yarn.
The number of windings of the winding yarn is preferably in the range of 5 to 20 times / inch from the viewpoint of stretchability.
Examples of such cover yarn include a Gabber yarn in which a polyurethane yarn (thickness: 17 dtex) is used as a core yarn, and a nylon semi-dalwoolie yarn is wound around the polyurethane yarn (8 times / inch).
By using the cover yarn formed in this way as a knitting yarn, a thin and uniform mesh warp knitted fabric with excellent stretchability can be obtained.

It is also possible to employ a wooly yarn that has been crimped by false twisting or the like as the knitting yarn.
Examples of the wooly yarn include a wooly yarn of nylon yarn (polyamide yarn) and a wooly yarn of tetron yarn (polyester yarn).
An example of such wooly yarn is nylon wooly yarn (thickness is 75 dtex).
By using this, strong elasticity like polyurethane yarn cannot be obtained, but there is an advantage that a mesh warp knitted fabric having soft elasticity and texture can be obtained.

As the knitting yarn, a raw yarn which is not crimped or the like is used.
Examples of the raw yarn include nylon yarn (thickness: 50 dtex / 36 filament).
Although the elasticity of the yarn itself is not obtained as compared with polyurethane yarn or wooly yarn, a thin and stable mesh warp knitted fabric having uniform rhomboid meshes can be obtained.
In other words, it uses a natural thread, so it has a certain stiffness in flexibility, and does not cause misalignment like a woven fabric, so it can function well as an industrial textile material. To do.

The mesh warp knitted fabric of the present invention has a structure that can be reduced in weight, such as a loop is not doubled or a knitted fabric portion is one wale, so that the basis weight (weight per unit area) is small. Knitted fabrics, for example, having a basis weight in the range of 40 grams / m ^{2 to} 100 grams / m ² are easily obtained.
Next, although an Example is described, this invention is not necessarily limited to an Example.

Using a tricot machine (made by Nippon Meyer Co., Ltd.), a front structure (1-0 / 1-1-1-1-2 / 1-1) and a back structure (0-0 / 0-1 / 2-2 / 2) -1) and a mesh warp knitted fabric having rhomboid meshes.
As the knitting yarn, a Gabber yarn in which a nylon semi-dull wooly yarn was wound around a core yarn of polyurethane yarn (thickness: 17 dtex) (8 times / inch) was used.
When the knitted mesh warp knitted fabric was visually observed, it was found that accurate rhombus meshes composed of small four sides were formed.
And the knitted fabric was also thin and delicate.
Further, even when tension was applied to the mesh warp knitted fabric many times, misalignment did not occur and an accurate parallelogram was maintained.

Various changes can be made to the present invention without departing from the scope of the claims.
The mesh warp knitted fabric of the present invention is mainly used for inner garments, but for outer garments, as a matter of course, agricultural materials such as insect nets, and further marine materials such as aquaculture nets, or building materials It can also be used as an industrial textile material for interiors.
It goes without saying that various changes can be made with respect to the type and thickness of the knitting yarn.
For example, polyester fibers, polyethylene yarns, polypropylene yarns, acrylic yarns as well as nylon yarns, and super fibers such as aramid yarns can also be used.
