When BACKGROUND ART cited as an example configured La Sseruresu locations as described above, when forming a pattern on the knitted fabric surface as described above, the liner yarn or the like to the region for forming the handle The pattern thread is knitted and the pattern is formed by the pattern thread. Also, in this type of Russell lace fabric, warps are knitted into chain stitches to form wales, and the warp that forms the wales tightens the pattern yarns from both the front and back sides. there were. For this reason, it has been attempted to remove part of the pattern yarn from the chain stitch and float it on the surface.

[0003]

In consideration of lace knitting in general, a region where the through holes are formed in a stitch pattern has a small thickness, and a region where a pattern is formed has a large thickness, which has a good feel and a high texture. It is regarded as quality. Therefore , the Russell lace is inferior in terms of quality when compared to the river lace which can form a thick pattern. However, since Russell lace is easier to manufacture than river lace, if it is possible to increase the thickness of the area where the pattern is formed in this Russell lace, it can be used for river lace while utilizing the characteristics that can be easily manufactured. It is possible to obtain lace knitting of high quality which is not inferior, and such a knitted fabric is desired.

An object of the present invention is to reasonably construct a Russell lace fabric which can reasonably increase the thickness of a region where a handle is formed.

A third feature of the present invention (claim 3 ) is that the thickening auxiliary yarn is knitted under tension.
Its action and effect are as follows.

A fourth aspect of the present invention (claim 4 ) is the pattern region according to claim 1, 2 or 3 , wherein a predetermined pattern is two-dimensionally formed on the surface of the knitted fabric by knitting the pattern thread. The thickening auxiliary yarns are knitted on the back side of the whole area of the above, and its action and effect are as follows.

A fifth aspect of the present invention (claim 5 ) is the pattern region according to claim 1, 2 or 3 , wherein a predetermined pattern is two-dimensionally formed on the surface of the knitted fabric by knitting the pattern thread. The thickening auxiliary yarn is knitted on the back surface side of a part of the area of the above, and its action and effect are as follows.

A sixth feature of the present invention (claim 6 ) is that, in claim 1, 2 or 3 , the thickening auxiliary yarn overlaps with a part of a lengthwise direction of a pattern yarn woven in the weft direction. It is woven into, and its action and effect are as follows.

A seventh characteristic of the present invention (claim 7 ) resides in that in any one of claims 1 to 6 , the pattern yarn is a liner yarn in a range of 200 denier to 300 denier. The action and effect are as follows.

[Operation] According to the first feature described above, the thickness of the region where the pattern is formed is increased only by knitting the thickening auxiliary yarn, which is more elastic than the pattern yarn, at the position where it overlaps with the back surface side of the pattern yarn. Not
Even when the tension at the time of knitting the handle yarn and the thickening auxiliary yarn is the same, since the thickening auxiliary yarn is knitted in an elastically stretched state, when it is knitted, the thickening auxiliary yarn shrinks. By the force, the handle thread is curved in a direction protruding from the surface, and the thickness of the handle region can be increased.
In particular, since the elastic thickening auxiliary yarn is provided along the handle yarn,
When the handle portion is touched, the thickening auxiliary yarn elastically expands as the curved handle yarn deforms, and the handle feels good.

According to the third feature, the thickening auxiliary yarn is knitted in a tensioned state. Therefore, when the thickening auxiliary yarn is knitted, the contracting force of the thickening auxiliary yarn is strongly applied to the pattern yarn. The thickness of the handle region can be further increased.

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

According to the fifth feature, since the thickening auxiliary yarn is knitted on the back surface side of a part of the pattern region, the thickness of a part of the pattern region can be increased as necessary.

According to the sixth feature, the thickness of the handle is locally increased by curving only a part of the length of the handle yarn in the longitudinal direction.

According to the seventh feature, 20 as the handle thread
By bending a relatively thick liner yarn of 0 denier to 300 denier with the thickening auxiliary yarn, the thickness can be more favorably increased.

[Effects of the Invention] Therefore, without using a special means such as removing a part of the pattern yarn from the chain stitch as in the prior art, only by knitting the thickening auxiliary yarn, the area where the pattern is formed The thickness was reasonably increased, and the warp knitted fabric having a good feel and texture was rationally constructed (Claim 1). Further, by tensioning the thickening auxiliary yarn, the thickness of the handle region can be further increased (Claim 3 ), and the overall thickness of the handle region can be reasonably increased (Claim 4 ). It is also possible to increase the thickness of any area to increase the stereoscopic effect.
5 ) It becomes possible to increase the thickness of only a small area of the area where the pattern is formed to create a local three-dimensional effect (claim 6 ). Even if a conventional pattern thread is used, the pattern can be obtained. It is possible to obtain the same thickness as that using a handle thread having a diameter larger than that of the thread (claim 7 ).

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 2 and 3, a plurality of warps 1 (nylon threads, etc.) are knitted into a chain stitch to form a plurality of wales X in parallel, and the plurality of wales X are adjacent to each other. Weft 2
(Nylon yarn or the like similar to warp yarn) is appropriately knitted to connect with each other, and the through hole 4 formed between the wale X and the weft yarn 2 forms a ground structure having a good lace pattern. The Russell lace ground L having an arbitrary pattern formed in a plane is formed by knitting the pattern thread 3 with respect to the ground structure over the width required in the weft direction and the width required in the warp direction. . In this Russell lace fabric L , the pattern yarn 3 is knitted simultaneously with the knitting of each of the warp yarn 1 and the weft yarn 2 (at the same time as the formation of the ground structure), so that the pattern region A is two-dimensionally formed on the knitted fabric surface. There is a macroscopic pattern area A which is, for example, a pattern area A having a floral pattern or the like shown in FIG.

More specifically, the warp 1 is knitted into a form having a needle loop 1n and a sinker loop 1s, and at the time of this knitting, the weft 2 knitted into the sinker loop 1s of a predetermined wale X is weighed in a predetermined amount in the warp direction. In the fed state, the knitting is performed on the sinker loop 1s of the adjacent wale X, and thereafter, the operation of knitting on the sinker loop 1s of the original wale X is repeated to form the ground structure. Is woven in the sinker loop 1s for the required length in the latitudinal posture, then folded back, and further, for the required length, the sinker loop 1s
By repeating the braiding, the pattern area A having a two-dimensional arbitrary shape is formed. That is,
A position in which one warp part in the warp direction pulled up when forming the sinker loop 1s is located on the front side, two warp parts forming the needle loop 1n are located on the back side, and is parallel to the weft 2 at a position sandwiched between them. The pattern thread 3 is arranged in the above, and the pattern thread 3 is not limited to the nylon thread, and a material suitable for the pattern and having an arbitrary thread diameter can be used. Especially, this handle thread 3 is from 200 denier to 3
A liner yarn of about 00 denier is used. In addition to this liner yarn, a thick yarn of about 100 denier, 50
A thin yarn of about denier or an optical yarn of about 150 denier is used.

The above construction is basically the same as the conventional Russell lace fabric, and the Russell lace fabric L of the present invention has the pattern thread 3 with respect to the back side of the pattern area A (the back side of the pattern thread 3). By providing the thickening auxiliary yarn 5 that is highly stretchable with respect to the entire area or a part of the area that overlaps the handle thread 3 in the direction along the A structure in which the thickness of the handle region A is increased is adopted. That is, as shown in FIG. 4, this thickening auxiliary yarn 5 is compared with the handle yarn 3 by spirally winding a fiber 5b such as cotton or nylon around a core material 5a made of polyurethane monofilament yarn and covering the core material 5a. In addition, (when compared with the warp yarn 1 and the weft yarn 2), a material having a large stretchability is used.
As shown in FIGS. 4 and 5, the thickening auxiliary yarn 5 is located at the same position as the position where the pattern yarn 3 is arranged when the pattern yarn 3 is knitted while maintaining a predetermined tension state, and is located on the back side of the pattern yarn 3. The thickening auxiliary yarn 5 is arranged. When the thickening assisting yarn 5 is knitted in this manner, it is desirable to tension the thickening assisting yarn 5 with a tension higher than that of the handle yarn 3.
Considering that the material has a property of expanding and contracting better than the pattern thread 3, the same effect can be obtained even when the thickening auxiliary thread 5 and the pattern thread 3 are knitted in a tensioned state with equal tension.

When the Russell lace material L is considered as a product, it is desired to increase the overall thickness of the pattern area A to increase the volume, or increase the thickness of a part of the pattern area A to form one pattern area. Three types of embodiments are conceivable when it is desired to change the stereoscopic effect in A or when it is not necessary to increase the thickness of the pattern region A. When these three types of embodiments are schematically represented, as shown in FIG. 6, in a pattern region A (where two pattern threads 3 are used) in which the thickness is increased in all regions, Two thickening auxiliary yarns 5 are arranged at the same position as the two pattern yarns 3 on the back surface side, and the pattern region A2 (two pattern yarns 3 are used in which the thickness is increased in a partial region) is used. 7), as shown in FIG. 7, the thickening auxiliary yarn 5 is arranged on the back surface side at the same position as the one pattern yarn 3 formed by the two pattern yarns 3 (one pattern yarn 3 Thickening auxiliary thread 5 so that it overlaps only part of
Further, in the handle region A3 where it is not necessary to increase the thickness, as shown in FIG. 8, the thickening auxiliary yarn 5 is disposed on the outer peripheral portion of the handle region 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 in which the thickening auxiliary yarn 5 is knitted is contracted, and the region is distorted or distorted. It is also conceivable to use the pattern area A for tactile and visual enhancement. That is, the area in which the thickening auxiliary yarn 5 is used is not limited to the area overlapping the pattern area A, and it is also possible to set it to any part in the area where the pattern area A does not exist. By using it, the quality of the Russell lace ground L is further improved.

By thus arranging the thickening auxiliary yarns 5, the finished Russell lace fabric L becomes a thin fabric with the warp yarns 1 and the weft yarns 2 at the portion where the through holes 4 are formed. An excellent lace pattern is formed, and not only the thickness of the pattern region A is increased due to the overlapping of the pattern yarn 3 and the thickening auxiliary yarn 5 in the pattern region A, but also in the portion where the thickening auxiliary yarn 5 is formed. As a result that the contracting force from the thickening auxiliary yarn 5 constantly acts on the handle yarn 3 in the bending direction, the compressing direction, or the combined direction thereof, the handle yarn 3 swells to the surface side, As a result, the thickness of the handle region A in which the thickening auxiliary yarn 5 is formed is increased. Moreover, handle thread 3
Since it is given a bulge by elastic biasing force, it gives a supple feel due to its elasticity when touched by hand, and it has a good feel due to its thickness as well as a good feel due to its flexibility. 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 stereoscopic effect to the pattern area A, and not only the thickness of the pattern area but also the volume feeling, the feel, and the visual shading of the pattern area A can be freely set according to the stereoscopic effect. ing.

[Other Embodiments] In the above embodiment, the monofilament polyurethane yarn is used as the thickening auxiliary yarn 5, but a multifilament yarn is used, or isoprene rubber, chloroprene rubber or the like is used instead of the polyurethane yarn. It is also possible to use the thickening auxiliary yarn 5 of the above material. In the above embodiment, the warp 1
Although a nylon thread is used as the weft thread 2, it is also possible to use a polyester thread, a silk thread, or a cotton thread. As the handle yarn, thick yarn, thin yarn, or optical yarn can be used as described in the above embodiment, and in this case, the yarn diameter may be any value.
