Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a plurality of wales formed by knitting a warp into a chain stitch to form a ground structure in which adjacent wales are connected to each other by knitting weft yarns. More particularly, the present invention relates to a technique for improving the quality of a Russell lace ground by knitting a pattern yarn for forming a pattern in a weft direction of the knitted fabric.

[0002]

2. Description of the Related Art Taking a Russell lace fabric as an example of a warp knitted fabric configured as described above, if a pattern is formed on the surface of a knitted fabric as described above, A pattern yarn such as a liner yarn is woven and a pattern is formed by the pattern yarn. Also, in this type of Russell lace ground, the warp is knitted into a chain stitch to form a wale, and the pattern yarn is tightened from both the front and back sides by the warp forming this wale, so the surface where it is difficult to obtain a sense of thickness there were. For this reason, some attempts have been made to remove a part of the pattern yarn from the chain stitch and float it on the surface.

[0003]

From the viewpoint of lace knitting in general, a region having a stitch-like through-hole has a small thickness, and a region having a pattern has a large thickness. Quality and are. Therefore, it is considered that the Russell lace as the warp knitted fabric is inferior in quality in comparison with the river lace which can form a thick pattern. However, Russell lace is easier to manufacture than River lace, so if it becomes possible to increase the thickness of the area where the pattern is formed in this Russell lace, it is possible to make use of the characteristics that can be easily manufactured. It is also possible to obtain inferior high quality lace knitting, and such a warp knitted fabric is desired.

An object of the present invention is to rationally construct a warp knitted fabric capable of increasing the thickness of a region where a pattern is formed without difficulty.

[0005]

A first feature of the present invention (claim 1) is that a plurality of wales formed by knitting a warp into a chain stitch are knitted with weft yarns so that adjacent wales are connected to each other. As the organization is formed,
In a warp knitted fabric in which a pattern yarn for forming a pattern is knitted in the knitting weft direction with respect to this ground structure, the pattern yarn is positioned at a position overlapping with the back side of the pattern yarn in the knitting fabric weft direction along the pattern yarn. The feature is that the thickening auxiliary yarn rich in elasticity is knitted, and its operation and effect are as follows.

A second feature of the present invention (claim 2) is that, in claim 1, the thickening auxiliary yarn is knitted in a tensioned state, and its operation and effect are as follows. is there.

A third feature of the present invention (claim 3) is that in claim 1 or 2, a predetermined pattern is formed two-dimensionally on the knitted fabric surface by knitting the pattern yarn. The point is that the thickening auxiliary yarn is knitted on the back surface side of the region, and the operation and effect are as follows.

According to a fourth aspect of the present invention, in the first or second aspect, one of the pattern regions in which a predetermined pattern is formed two-dimensionally on the surface of the knitted fabric by knitting the pattern yarn. The point that the thickening auxiliary yarn is knitted on the back surface side of the region of the portion, the operation and the effect are as follows.

A fifth feature of the present invention (claim 5) is that in claim 1 or 2, the thickening auxiliary yarn is knitted at a portion overlapping with a part of the length of the pattern yarn knitted in the weft direction. The operation and effect are as follows.

A sixth feature of the present invention (claim 6) is that, in any one of claims 1 to 5, the pattern yarn is a liner yarn in a range of 200 denier to 300 denier. The operation and effect are as follows.

According to the first feature, by knitting a thickening auxiliary yarn having more elasticity than the pattern yarn at a position overlapping with the back side of the pattern yarn, the thickness of the region where the pattern is formed only increases. However, even when the tension at the time of knitting the pattern yarn and the thickening auxiliary yarn is the same, the thickening auxiliary yarn is knitted in an elastically stretched state. The pattern yarn can be curved in a direction protruding from the surface by the contraction force of the yarn, so that the thickness of the pattern region can be increased. In particular, since the thickening auxiliary yarn stretches along the pattern yarn, the thickening auxiliary yarn elastically expands as the pattern yarn in a curved state deforms when touching the part of the pattern. The feel is good.

According to the second feature, since the thickening auxiliary yarn is knitted in a tension state, when the knitting is performed, the contraction force of the thickening auxiliary yarn is made to act strongly on the pattern yarn. The thickness of the pattern region can be further increased.

According to the third feature, since the thickening auxiliary yarn is knitted on the back surface side of the entire area of the pattern area, the thickness of the entire pattern area is increased.

According to the fourth feature, since the thickening auxiliary yarn is knitted on the back side of a part of the pattern area, the thickness of the part of the pattern area is increased as necessary.

According to the fifth feature, only a part of the pattern yarn in the length direction is curved to locally increase the pattern thickness.

According to the sixth feature, as the pattern yarn, 20
A relatively thick liner yarn having a thickness of 0 denier to 300 denier is curved by the thickening auxiliary yarn so that the thickness can be more favorably increased.

[Effects of the Invention] Accordingly, the knitting of the thickening auxiliary yarn is not required, but a special means such as removing a part of the pattern yarn from the chain stitch as in the prior art. The warp knitted fabric having a reasonably thick feel and good feel and texture was reasonably constructed (claim 1). Further, by tensioning the thickening auxiliary yarn, the thickness of the pattern area can be further increased (claim 2).
It is also possible to increase the thickness of the entire pattern area without difficulty (Claim 3) and increase the thickness of an arbitrary area in the pattern area to increase the three-dimensional effect (Claim 4). It is possible to create a local three-dimensional effect by increasing the thickness of only the narrow region (claim 5), and even if a conventional patterned yarn is used, a patterned yarn having a diameter larger than the diameter of the patterned yarn can be obtained. The same thickness as that used can be obtained (claim 6).

[0018]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 2 and 3, a plurality of warp yarns 1 (nylon yarns or the like) are knitted into a chain stitch to form a plurality of wale Xs in parallel. Weft 2
By appropriately weaving (such as a nylon thread like a warp), they are connected to each other, and a through-hole 4 formed between the wale X and the weft 2 forms a ground structure having a good lace pattern. Russell lace ground L in which an arbitrary pattern is formed in a plane by knitting the pattern yarn 3 with the required length in the weft direction and the required width in the warp direction with respect to the ground structure is configured. . The Russell lace fabric L is an example of a warp knitted fabric, and the pattern yarn 3 is woven at the same time as the knitting of the warp 1 and the weft 2 (at the same time as the formation of the ground structure), so that a two-dimensional pattern is formed on the surface of the knitted fabric. An area A is formed, and this pattern area A is a macroscopic pattern area A having a flower pattern shown in FIG. 1, for example.

More specifically, the warp 1 is knitted into a form having a needle loop 1n and a sinker loop 1s. At the time of this knitting, the weft 2 knitted in the sinker loop 1s of a predetermined wale X is moved by a predetermined amount in the warp direction. In the sent state, the knitting is performed on the adjacent sinker loop 1s portion of the wale X, and thereafter, the operation of knitting on the sinker loop 1s of the original wale X is repeatedly performed to form the ground structure. Is knitted into the sinker loop 1s in the required orientation in the weft orientation, then folded back and further the sinker loop 1s in the required length
By repeating the knitting, a pattern region A having a two-dimensionally arbitrary shape is formed. That is,
One warp portion in the warp direction pulled up at the time of forming the sinker loop 1s is located on the front side, and the two warp portions forming the needle loop 1n are located on the back side, and are parallel to the weft 2 at positions sandwiched between the warp portions. The pattern yarn 3 is arranged, and the pattern yarn 3 is not limited to a nylon yarn, and it is possible to use a material suitable for the pattern and having an arbitrary yarn diameter. In particular, the pattern yarn 3 is from 200 denier to 3
A liner yarn of about 00 denier is used. In addition to this liner thread, a thick ground yarn of about 100 denier, 50
A thin yarn of about denier or a light yarn of about 150 denier is used.

The above structure is basically the same as the conventional Russell lace ground, and the Russell lace ground L of the present invention is designed so that the pattern yarn 3 is located on the back side of the pattern area A (the back side of the pattern yarn 3). In the direction along, the thickening auxiliary yarn 5 rich in elasticity is provided for the entire region or a part of the position overlapping the pattern yarn 3, and the contraction force of the thickening auxiliary yarn 5 A configuration in which the thickness of the pattern region A is increased is employed. In other words, this thickening auxiliary yarn 5 is compared with the patterned yarn 3 by winding a core material 5a made of a polyurethane monofilament yarn with a fiber 5b such as cotton or nylon in a spiral shape as shown in FIG. In addition, a material having a large elasticity (compared to the warp 1 and the weft 2) is used, and when the entire thickness of the pattern region A is increased,
As shown in FIGS. 4 and 5, the thickening auxiliary yarn 5 is maintained at a predetermined tension state and at the same position as the position where the pattern yarn 3 is arranged at the time of weaving the pattern yarn 3, at the back side from the pattern yarn 3. The auxiliary thickening yarn 5 is arranged. When the thickening auxiliary yarn 5 is knitted in this way, it is desirable to tension the thickening auxiliary yarn 5 with a tension higher than the pattern yarn 3.
In view of the fact that is a material that expands and contracts better than the pattern yarn 3, the same effect can be obtained even when the thickening auxiliary yarn 5 and the pattern yarn 3 are woven under tension with the same tension.

Further, when the Russell lace ground L is considered as a product, it is necessary to increase the overall thickness of the pattern area A to increase the volume, or to increase the thickness of a part of the pattern area A to increase the thickness of one pattern area. Three types of embodiments are conceivable in which it is desired to change the three-dimensional appearance in A, or when it is not necessary to increase the thickness of the pattern area A. When these three types of embodiments are schematically represented, as shown in FIG. 6, in a pattern region A (in which two pattern yarns 3 are used) in which the thickness in all regions is increased, Two thickening auxiliary yarns 5 are arranged on the back side at the same position as the two pattern yarns 3, and a pattern region A2 (two pattern yarns 3 are used in which the thickness is increased in a part of the region. 7), as shown in FIG. 7, the thickening auxiliary yarn 5 is arranged on the back surface side at the same position as one of the pattern yarns 3 formed by the two pattern yarns 3 (one pattern yarn 3). Auxiliary thickening thread 5 so that it overlaps only part of
Further, in the pattern area A3 where it is not necessary to increase the thickness, as shown in FIG. 8, the thickening auxiliary thread 5 is arranged on the outer peripheral portion of the pattern area A. . or,
From a different point of view, for example, by knitting the thickening auxiliary yarn 5 in a region surrounding the pattern region A, the ground structure of the region where the thickening auxiliary yarn 5 is knitted is shrunk, and the region is shrunk or deformed. On the other hand, it is also conceivable to use the pattern area A to enhance the touch and the visual sense. In other words, the region where the thickening auxiliary yarn 5 is used is not limited to the region overlapping with the pattern region A, and can be set to an arbitrary portion in the region where the pattern region A does not exist. By using this, the quality of the Russell lace ground L is further improved.

By arranging the thickening auxiliary yarn 5 in this manner, the finished Russell lace ground L becomes thin with the warp 1 and the weft 2 at the portion where the through hole 4 is formed. In the pattern region A, not only the thickness of the pattern region A is increased due to the overlap of the pattern yarn 3 and the thickening auxiliary yarn 5 but also the portion where the thickening auxiliary yarn 5 is formed. As a result of the shrinkage force from the thickening auxiliary yarn 5 constantly acting on the pattern yarn 3 in the bending direction, the compression direction, or the direction in which each is synthesized, the pattern yarn 3 swells to the surface side, As a result, the thickness of the pattern region A on which the thickening auxiliary yarn 5 is formed increases. Moreover, pattern yarn 3
Is swelled by the elastic biasing force, so when touched by hand, it gives a supple feel due to elasticity, and in addition to a good feel due to thickness, a good feel due to flexibility In particular, the pattern area A
In the case where the thickening auxiliary yarn 5 is arranged only in a part of the area, the pattern yarn 3 having the same yarn diameter is used, but the thickness is increased only in the region where the thickening auxiliary yarn 5 is arranged. It is also possible to give a three-dimensional effect to the pattern area A, and it is possible to freely set not only the thickness of the pattern area but also the volume feeling, the feel, and the visual shadow of the pattern area A with the three-dimensional feeling. ing.

[Alternative Embodiment] In the above embodiment, a monofilament polyurethane yarn is used as the thickening auxiliary yarn 5. However, a multifilament yarn is used, and instead of the polyurethane yarn, isoprene rubber, chloroprene rubber, or the like is used. It is also possible to use a thickening auxiliary yarn 5 made of the above material.
In the above embodiment, a nylon yarn is used as the warp 1 and the weft 2; however, a polyester yarn, a silk yarn, and a cotton yarn can also be used. As described in the above embodiment, the pattern yarn may be a thick ground yarn, a thin ground yarn, or a light yarn. In this case, the yarn diameter may be an arbitrary value.
