Description

  As one kind of race ground, a gradation race in which the color tone sequentially changes in the width direction is known.

When producing this kind of gradation lace, a lace of a predetermined color ground (typically, white) is knitted to obtain a raw material, and one end of the raw material in the width direction is immersed in a dye to perform a dyeing process. I went. In order to obtain the desired "gradation", it is necessary to change the amount of dyeing in the lace width direction.For example, when dyeing the lace width direction end side darker and the inner side lighter, the width direction end side, the dye The dyeing concentration was changed by lengthening the immersion time. The adjustment of the dyeing time is performed by, for example, immersing the end in the width direction longer in one dyeing operation, or increasing the number of times of dyeing (the number of times of immersion in the dye) toward the end in the width direction.
This type of work has heretofore been a manual work, and no prior art documents can be mentioned.

  On the other hand, Patent Documents 1, 2.3, and the like propose a technique in which a yarn having different dyeing properties for a specific dye is used for each knitted fabric region to obtain a multicolor product for each region on a single lace ground. ing.

  When performing hand dyeing to obtain a gradation race, there are the following problems.

1. Since the operation is a manual operation including a plurality of dyeing steps or a manual operation for performing a predetermined dyeing time operation, it is practically impossible to produce a desired gradation race in a large amount and in a short delivery time. is there. According to the studies by the inventors, for example, it can be manufactured in small-scale production up to about 5000 m, but cannot be mass-produced in 500,000 m or the like. If you dare to do this, the processing fee will be enormous, and the delivery time will be a long time that is usually not acceptable.
2. In the case where the above-mentioned conventional method involving manual work is adopted, the same gradation is obtained in the knitting direction orthogonal to the width direction because the lace material is dyed at different densities in the width direction. In other words, it is practically impossible to give gradation in the knitting direction.
3. In addition, in the case of adopting this conventional method, in order to dye the lace ground with a specific dye at one end in the width direction, gradation is provided at both ends in the width direction of the lace ground (gradation at both ends). It is necessary to work separately on the other side.

  Print dyeing is also possible, but it is impossible to sequentially place colors in specific places, and when targeting laces with many holes, it is possible to add unique gradation to areas with different degrees of dyeing according to the lace pattern It can be difficult.

  On the other hand, in the techniques disclosed in Patent Literatures 1 and 2, dyeing goes through a complicated stage (Patent Literature 1), or a special twisted yarn needs to be manufactured (Patent Literature 2). According to the technique disclosed in Patent Document 3, it is not possible to obtain a race whose hue changes sequentially.

An object of the present invention is to obtain a lace similar to a gradation lace, which has been conventionally obtained only through a manual dyeing process, in a rational and simple manner. An object of the present invention is to obtain a technology capable of coping with the above.
It is a further object of the present invention to provide a lace ground whose color tone changes sequentially not only in the width direction of the lace ground but also in the knitting direction.

To achieve the above object, the present application provides
A ground structure comprising a weft knitted over between wales and wales, the ground tissue is organized from a weaving yarn knitted, the braid yarns of the lace ground which pattern is Ru is formed across a plurality of wales in accordance with the distribution The feature configuration of
The weft or the braided yarn or both of them are composed of two or more fibers including at least a first fiber and a second fiber having different dyeing properties for a specific dye,
The knitting structure in the width direction of the lace ground is provided with the same yarn type yarn transfer portion where the same yarn type yarn crosses over a plurality of wales on the same course, and the same yarn type yarn transfer portion of different yarn types is provided. It is distributed and arranged in the knitting direction of the race ground,
Ri Do a predetermined number of courses, and by a plurality of unit regions widthwise end portion is set in the knitting direction, the lace ground is constructed so as to be divided into at least three regions,
With respect to the unit area, in the comparison between the unit areas located in the width direction of the lace ground, the density of the first fiber is gradually increased in at least three stages with respect to the density of the second fiber is an inclined structure,
At the end of the width direction of the lace ground, in the first fiber or the one Rukoto end portion consisting of only one it has been formed of the second fiber.

In order to obtain a race ground of this configuration,
A ground structure comprising a weft knitted over between wales and wales, the ground tissue is organized from a weaving yarn knitted, lace that form a pattern across a plurality of wales in accordance with the distribution of the braid yarns the a knitting method,
The weft or the braided yarn or both of them, composed of two or more fibers including at least a first fiber and a second fiber having different dyeing properties for a specific dye,
In the knitting structure in the width direction of the lace ground, the same yarn type yarn transfer portion where the same yarn type yarn crosses over a plurality of wales on the same course is provided, and the same yarn type yarn transfer portion of different yarn types is provided. Distributed in the knitting direction of the race ground,
Ri Do a predetermined number of courses, and by a plurality of unit regions widthwise end portion is set in the knitting direction, divides the lace ground in at least three regions,
With respect to the unit area, in the comparison between the unit areas located in the width direction of the lace ground, the density of the first fiber is an inclined structure that is sequentially increased in at least three stages with respect to the density of the second fiber ,
An end portion composed of only one of the first fiber and the second fiber may be formed at an end in the width direction of the lace ground .

The lace ground having this configuration is provided with the same yarn type yarn crossing portion that is knitted over the same course over a plurality of wales in a unit area configured with a predetermined number of courses. That is, a region (area) where the same yarn type (in other words, yarn dyed in the same color) extends in the course direction, which is the width direction of the lace ground, is formed, and different yarn types are used for different yarn types. Are distributed in the knitting direction of the lace ground. This distributed arrangement may be such that the same yarn type yarn crossing portions of two yarn types are uniformly distributed and arranged in the form of one course or two courses in the knitting direction of the lace ground, The arrangement may be made while changing the length and / or appearance ratio of the same yarn type yarn crossing portion according to the form.
With this configuration, after dyeing, the same yarn type yarn crossing portions of different colors are dispersed and appear on the surface according to the design of the knitting structure. Then, in the unit area comparison configured with a predetermined number of courses, in the comparison between the unit areas located in the width direction of the race ground, the density of the first fiber is at least three stages with respect to the density of the second fiber. The structure is such that the texture gradually increases.

That is, in the width direction of the lace ground, when compared between the unit regions, the density of the first fiber is increased, for example, for the first fiber (for example, for the second fiber, Lower). Here, a unit area of 100% of the first fiber and 0% of the second fiber may be formed, or a unit area of 0% of the first fiber and 100% of the second fiber may be formed. Good. If such a unit area is provided at the end in the width direction of the lace ground, this area becomes the end part of the present invention. However, among the three stages that change stepwise, at least in the intermediate stage, there is a region in which the first fibers are contained at a predetermined percentage and the second fibers are contained at the corresponding percentages.

  Regarding the change in the ratio, adjustment of the length in the race width direction of the cross section of the same yarn type yarn, adjustment of the number of courses as described below, and further adjustment of the thickness of the yarn used in the area, etc. It is possible to adjust the density between them.

  When the lace material knitted in this manner is dyed, the first fibers and the second fibers having different dyeing abilities will have different colors due to the dyeing of the specific dye. Further, since the densities of these fibers are sequentially changed in at least three stages, a lace fabric having an appearance similar to a gradation can be obtained by simply dyeing the entire knitted lace fabric uniformly.

Of course, it is also possible to use a different dye for the second fiber, while using a dye for the first fiber, so that each fiber has a specific desired color.
As a result, the problem of manual work, which was a problem in the conventional technology, was successfully solved.
In addition, in the comparison between the unit areas, the density of the first fibers is sequentially increased with respect to the density of the second fibers. It is preferable that the number of yarn type yarn transfer portions is large.

  In the lace ground of this configuration, in the comparison between the unit areas, the density of the first fibers is sequentially increased with respect to the density of the second fibers. The knitting can be performed by increasing the number of the same yarn type yarn transfer portions including fibers.

  As described above, the adjustment of the density of the first fiber and the density of the second fiber is performed by adjusting the number of courses including the first fiber and the course including the second fiber included in a unit area including the predetermined number of courses. By adjusting the number of courses with the number, the adjustment can be made by the simplest method, and the intended gradation race can be obtained relatively easily.

Further, the same yarn type yarn transfer portion is formed as the same yarn type continuous portion in which the same yarn type and different wefts or the knitted yarns are continuous in the width direction of the lace ground,
It is preferable that the higher the density of the first fibers, the greater the number of the same yarn type continuous portions in the knitting direction of the lace ground.

The race ground of this configuration,
The same yarn type yarn transfer portion is formed as the same yarn type continuous portion in which the same yarn type and the different weft or the knitting yarn are continuous in the width direction of the lace ground,
The region where the density of the first fibers is higher can be knitted by increasing the number of the same yarn type continuous portions in the knitting direction of the lace ground.

  Regarding the same yarn type yarn crossing portion described so far, it is not described whether this portion (region) is formed by a single weft or braided yarn or by a plurality of these yarns. (In other words, not limited). In general, in a warp knitted fabric, there is a limit to the number of wales that a single weft or braided yarn can deflect (for example, 5 wales in the case of a river machine). Therefore, if a single weft or braided yarn forms the same yarn type yarn crossing portion, there is a limit to its length.

  On the other hand, by forming the same yarn type yarn jumping portion as the same yarn type continuous portion and by combining a plurality of yarns in the width direction arrangement, the length of the same yarn type yarn jumping portion in the race ground width direction can be freely set. The degree of gradation (the degree of color change in the width direction) can be freely adjusted, and the selectivity of the pattern is significantly improved.

Further, in the lace ground, the same yarn type continuous portion is formed by wefting the number of the wefts or the knitting yarns corresponding to the number of wales positioned in the width direction of the lace ground and continuously extending in the width direction of the lace ground. It can be configured to be knitted.
By adopting this configuration, for example, a lace ground unique to the present application can be realized as the same yarn type by a weft or a braided yarn that is sequentially braided between adjacent wales.

In addition, in the racing areas described so far,
A third fiber and a fourth fiber are provided as the weft or the knitting yarn,
A fiber thicker than the fourth fiber is used as the third fiber,
Regarding the knitting structure in the knitting direction of the lace ground, it is preferable that a region in which the density of the third fiber is higher than the density of the fourth fiber is formed in comparison between unit regions in the direction.
The race ground of this configuration,
Using a third fiber and a fourth fiber as the weft or the knitting yarn,
Using a fiber thicker than the fourth fiber as the third fiber,
Regarding the knitting structure in the knitting direction of the lace ground, it can be realized by forming a region where the density of the third fibers is higher than the density of the fourth fibers in comparison between unit regions in the direction.

  The technology described so far is a method for applying a gradation in the width direction of the lace ground. However, in the knitting direction, a third fiber and a fourth fiber are provided, and the same type is provided by changing the thickness of the yarn. Also in the configuration using the fibers of the above, it is possible to change the color after dyeing by changing the density.

  Here, the thicker the yarn (higher density), the deeper the color, and the thinner the yarn (lower density), the lighter the color.

  The selection of the yarn type may be such that the third fiber and the fourth fiber are either the first fiber or the second fiber described above, respectively, or another yarn type may be employed. As an example of selecting another type, it is possible to use cations as the first fibers, nylon as the second fibers, and viscose rayon as the third and fourth fibers.

  As described above, in the design stage of the structure of the lace ground, the density of the first fiber and the second fiber per unit area is inclined to change by using the same yarn type yarn crossing portion (the same yarn type connecting portion). By attaching, the lace was mechanically knitted, and a predetermined dyeing operation was performed to obtain a gradation lace intended by the present application. That is, an arbitrary gradation was able to appear at a predetermined place.

  With this technology, it is possible to dye in a cloth state, and to produce a gradation product by mass production.

An embodiment of the present application will be described below with reference to the drawings.
FIG. 1 is a diagram showing an appearance of a lace ground 1 which is a warp knitted fabric as viewed from a surface side.
The feature of the present application is that the color tone of the lace ground 1 which is a warp knitted fabric sequentially transitions in the width direction D1 of the lace ground, as shown in FIG. In this example, in the width direction D1 of the race ground, the color tones of the left and right end portions Ze, the inner middle portions Zm and the center portion Zc are sequentially changed. FIG. 4 shows an enlarged structure of the portion A in FIG. 4, and FIG. 6 shows an enlarged structure of the portion B. FIG. 5 is an enlarged view of the structure of a region Zm in FIG. The magnification of FIG. 6 is smaller than the magnification of FIG.

In the following description, a case of manufacturing a river race ground 1 using a river machine (not shown) according to a preferred embodiment will be described first. Specific examples of the yarn to be used are also shown, but these examples are merely preferable examples.
FIGS. 2A and 2B show the structures when the river lace ground 1 is viewed from the knitted fabric surface side. As shown in FIG. 2 (a), a bobbin thread 7 (yarn type: nylon, thickness: 30 to 50) is formed on a river lace fabric 1 in a warp knitted fabric, which is a basis of a structure extending in a knitting direction D2 called a wale W. (Denier) is provided as a warp, and a backwarp BW (thread type: nylon cover thread having a polyurethane core, thickness: 140 to 420 denier) is knitted in the bobbin thread 7 in the width direction of the knitted fabric. Further, a front warp FW (yarn type: nylon, thickness: 30 to 50 denier) is knitted on the front side of the back warp BW with respect to the structure composed of the bobbin yarn 7 and the back warp BW. Since the back warp BW and the front warp FW constitute the ground structure 4 (net N) of the warp knitted fabric, they become wefts.

  The direction of weaving these back warp BW, front warp FW, or gimp yarn 8 and liner yarn 9 described later is the width direction D1 of the lace ground orthogonal to the knitting direction D2 described above.

  Back warp BW and front warp FW are performed by wefting between adjacent bobbin yarns 7 or between a predetermined number of bobbin yarns 7 in the same course C, and knitting proceeds. As shown in FIG. 2 (a), when viewed from the surface side of the knitted fabric, the yarn is positioned on the back side of the bobbin yarn 7 when swinging to the right with respect to the bobbin yarn 7, and is positioned on the front surface side of the bobbin yarn 7 when swinging to the left. Form. Conversely, the front warp FW is knitted so as to be positioned on the front side when the bobbin thread 7 is swung to the right and on the back side when swung to the left.

  The ground structure 4 of the river lace ground 1 is completed with a bobbin yarn 7 (warp), a back warp BW (weft) and a front warp FW (weft). Then, in the river lace ground 1, for the purpose of patterning and the like, as shown in FIG. 2B, a gimp yarn 8 (yarn type: yarn type) is provided between the front warp FW and the back warp BW with respect to the ground structure 4. Cation, nylon: or cotton, etc., thickness: about 50 to 150 denier) is inserted, and liner thread 9 (thread type: nylon, cation: or cotton, etc., thickness: about 300 denier) is provided on the front side of front warp FW. Is inserted.

  FIG. 2B shows a structure in which a single representative gimp yarn 8 and a single representative liner yarn 9 are inserted into the ground structure 4 of FIG. 2A. As can be seen from this figure, the yarn swing similar to the back warp BW described above is performed on the gimp yarn 8, and the yarn swing similar to the front warp FW is performed on the liner yarn 9.

  In the case of the river lace ground 1, the number of gimp yarns 8 is generally about 60, and the number of liner threads 9 is generally about 60.

  In the present application, in order to make the color appearing on the surface side of the lace ground 1 a problem, the use of the liner thread 9 (how to use the thread type) mainly becomes a problem. Further, since the liner yarn 9 plays a major role in forming the pattern, a thick yarn is used for the weft.

As described above, when the knitted fabric is viewed in the thickness direction T, the liner yarn layer 90, the front warp layer FWL, the gimp yarn layer 80, and the back warp, as shown in FIG. It is composed of a layer BWL.
The positional relationship of each yarn in the front and back direction of the knitted fabric is determined by the positional relationship of the reed in the knitting operation. Due to the knitting configuration, it is natural that the yarns are knitted together in the front and back directions according to the configuration shown in FIG. 2B.
The arrangement of the respective layers (the liner yarn layer 90, the front warp layer FWL, the gimp yarn layer 80, and the back warp layer BWL) in the above-described race ground 1 in the back-to-back direction T of the river lace ground includes the front warp layer FWL and the gimp yarn. It is also possible to adopt a configuration in which the liner yarn layer 90, the gimp yarn layer 80, the front warp layer FWL, and the back warp layer BWL are arranged from the surface side of the lace ground 1 in a positional relationship where the layer 80 is reversed in the front and back directions. is there.

  Next, a characteristic configuration of the present application for obtaining the gradation shown in FIG. 1 in the river race ground 1 will be described. In the description, FIGS. In the gradation lace according to the present application, since the color appearance of the lace viewed from the front side is a problem, the yarns (mainly the liner yarns 9 described above) appearing at each part of the lace are problematic. However, there are areas where the gimp yarn 8, the front warp FW, and the back warp BW are exposed depending on the race part.

1 Use of Yarn As described above, the river lace ground 1 according to the present invention is provided as a weft (back warp BW, front warp FW) or a braided yarn (liner yarn 9, gimp yarn 8) or both of them. Two or more fibers including at least a first fiber and a second fiber having different dyeing properties for a specific dye are used.

  In the following description, in order to facilitate understanding, the exposed yarn may be referred to as “exposed yarn”. The combination of the first fiber and the second fiber is, for example, nylon and cation. As the dye, an acid dye is used for nylon and a cationic dye is used for cation. Further, when cotton yarn or viscose rayon is used, a reactive dye is used. Therefore, when a knitted fabric containing two types of yarn is dyed with the same dye, a color difference according to the type of yarn appears. Furthermore, when it is desired to dye the first fiber in a specific first color and the second fiber in a specific second color, a dyeing operation suitable for each fiber may be selected and the dyeing operation may be performed. In this case, dyeing may be performed by one bath dyeing, or may be sequentially performed by each dye. However, the gradation targeted by the present application can be obtained by performing a dyeing operation on the raw fabric knitted in a predetermined tissue form.

In the example shown in FIG. 1, in the width direction D1 of the lace ground, both left and right portions are provided with both end portions Ze, the inside portions thereof are provided with an intermediate portion Zm, and the center portion is provided with a central portion Zc. Here, both ends Ze are end parts, respectively.

  In this example, the exposed yarn of both end portions Ze is a single cationic yarn type, the exposed yarn of the intermediate portion Zm is a yarn using cation and nylon, and the exposed yarn of the central portion Zc is a single yarn yarn of nylon. This is an example. The thickness of the yarns forming these patterns is basically about 300 denier because the liner yarns 9 are basically formed.

  In the net N which is seen through, a thin thread (thinner than the liner thread) is used as the front warp FW or the back warp BW according to the use of the thread at that portion. Here, "according to the use of the yarn at the site" means, for example, when the liner yarn at the corresponding site is a nylon yarn, a fine nylon yarn is used for the front warp FW of the corresponding site, and a fine nylon yarn is used for the back warp BW. Or polyester yarn is used.

  That is, the color density changes between the area a1 and the area a2 shown in the upper left of FIG. 4, and this change is caused by a different thickness in the configuration using the same type of yarn as described later. This is due to the use of the yarn of the sword. The nylon fiber (an example of a third fiber: about 300 denier because the yarn is the liner yarn 9) used in the a2 part is the nylon fiber (the Example of four fibers: This yarn has a front warp FW and is 30 to 40 deniers).

  As described above, in the present application, firstly, there is a feature in the use of yarn in consideration of dyeing, and further, the knitting structure is devised.

(Same yarn type yarn transfer section)
The lace ground according to the present application is formed such that the knitting structure in the width direction D1 of the lace ground is provided with the same yarn type yarn crossover portion 2 in which the same yarn type yarns cross over a plurality of wales on the same course.

This specific configuration will be described with reference to FIGS. 3, 4, and 5.
FIG. 3 is an explanatory example for facilitating the understanding of the characteristic configuration according to the present application. This example is an example in which a single liner yarn 9 constitutes the same yarn type yarn transfer section 2, and each identical yarn In the seed yarn transfer section 2, the liner yarn 9 transfers the reciprocating yarn in units of 4 wales W.
Further, with respect to different yarn types (the cationic liner yarn as the second fiber is indicated by 9c and the nylon liner yarn as the first fiber is indicated by 9n), the following configuration is adopted.
In the region Ze shown in FIG. 3A, this region is formed only by the cation liner yarn 9c as the second fiber. Then, in the right area Zm1 moved in the race ground width direction D1, as shown in FIG. 3 (b), the same yarn type yarn crossing portion 2c of the second fiber and the first fiber yarn crossing portion 2n are separated by 2 The regions are alternately dispersed in units of course to form this region. In the area Zm2 shown in FIG. 3 (c), the same yarn type yarn transfer portion 2c of the second fiber has two courses, and the yarn transfer portion 2n of the first fiber has four courses. In the area Zc shown in FIG. 3D, this area is formed only by the nylon liner thread 9n as the first fiber.

  The example shown in FIG. 1 is an example designed according to the same concept as in FIG. 3, in which both end portions Ze have a configuration similar to FIG. 3A and a central portion Zc has a configuration similar to FIG. Has been adopted. The intermediate portion Zm is configured by arranging the regions Zm1 and Zm2, and corresponds to FIGS. 3B and 3C. Various contrivances have been made regarding the length setting and the like.

Hereinafter, description will be made with reference to FIGS.
In these drawings, a straight line extending in the vertical direction indicates the position of the bobbin thread 7 (the position of the wale W) in the river lace ground 1, and the thick solid line corresponds to each of the plurality of cationic liner threads 9c. Dashed thick lines correspond to the plurality of nylon liner threads 9n, respectively. Further, thin solid lines correspond to a plurality of front warp FWs and back warp BWs.

  These lines show the form of yarn transfer between the wales W of each yarn.

  In FIG. 4, the yarn swinging portion of the pair of cationic liner yarns 9c located at the left end in the drawing is an end decoration portion 20 of the lace ground 1 generally called "scallop". Inside it, one side of both ends Ze described above is shown, and to the right are the middle part Zm (Zm1, Zm2) and the center part Zc. The thread usage (difference between the cation and the nylon) at these sites has been described above.

  On the other hand, regarding the yarn swing, as shown in the example illustrated in FIG. 3, in addition to the structure of reciprocating between the same wale W in units of two courses continuous in the knitting direction D2, reciprocating between different wale W. (That is, the liner yarn moves in the race width direction D1), and the reciprocation between the wales W also reciprocates a few courses apart (in the middle, a plurality of courses of the same yarn type yarn crossing portion 2 of another type of yarn are provided). Various configurations are employed.

Further, the object of the present application employs the following configuration in order to make the same yarn type yarn jumping section 2 a unique distribution state.
That is, in the examples shown in FIGS. 4 and 5, in addition to the example in which the same yarn type yarn transfer section 2 described in FIG. An example in which D1 is formed continuously is also shown. FIG. 5 is an enlargement of the region indicated by Zm in the race ground width direction D1 and the region indicated by E in the knitting direction D2 in FIG.

For example, in the lower left part of FIG. 5, the same cation type yarn type yarn crossing portion 2c is continuously formed at a position four courses from the top and bottom in the figure, and the same yarn type and different liner yarns 9c, 9c, 9c are formed on the lace ground. Are formed as the same yarn type continuous portion 3 which is continuous in the width direction D1. From the left side in the figure, the liner yarn 9c is oscillated across 6, 4, and 2 wales, and a portion where another liner yarn 9c, 9c overlaps with the same wale W is formed, and its continuity is ensured. ing. As a result, the same yarn type yarn crossing portion 2 is configured to form the same yarn type continuous portion 3 in a state of extending over 10 wales. In this vicinity, a similar structure is adopted at a position advanced by one course in the knitting direction and at a position further advanced by three courses.
On the other hand, in the upper right part of FIG. 5, the same yarn type and different liner yarns 9n and 9n are continuously formed at the position seven courses back from the upper side of the figure, with the same yarn type and different liner yarns 9n and 9n. It is formed as the same yarn type continuous portion 3 which is continuous in the width direction D1. From the left side in the figure, the liner yarn 9n is oscillated across 5 and 2 wales, respectively, and another liner yarn 9n and 9n are formed in the same wale W to form a portion where the liner yarns 9n and 9n overlap with each other so that the continuity is ensured. I have. As a result, the same thread type continuous portion 3 is configured to form the same thread type continuous portion 3 in a state where the same thread type thread transition portion 2 extends over 6 wales. In this vicinity, a similar structure is employed at a position returned by one course in the knitting direction and at a position returned by two courses in the knitting direction.
The same yarn type continuous portion 3 deflects a number of wefts or braided yarns corresponding to the number of wales located in the width direction of the lace ground (the number of wales = 1 or half thereof). It may be knitted continuously in the width direction of the race ground.

  As described above, in the gradation lace according to the present application, the knitting is advanced while forming the same yarn type yarn crossing portion 2 (or the same yarn type continuous portion 3). The race ground 1 is related to a unit area composed of a predetermined number of courses (16 courses in the example shown in FIG. 3), and may be the same yarn type yarn crossing portion 2 of different yarn types (the same yarn type continuous portion 3). ) Are distributed in the knitting direction of the lace ground, and in the comparison between the unit areas located in the width direction D1 of the lace ground 1, the density of the first fibers is sequentially increased at least in three stages with respect to the density of the second fibers. (In the example described, the density of nylon increases in at least three steps).

In other words, as shown in FIG. 3, in the comparison between the unit areas, the density of the first fibers is sequentially increased with respect to the density of the second fibers. Is increased.
Further, as shown in the examples of FIGS. 4 and 5, when the same yarn type continuous portion 3 is provided, the length of the same yarn type yarn transfer portion 2 can be appropriately adjusted. The appearance of the yarn is adjusted arbitrarily.

  On the other hand, if the thickness of the same yarn type is described in terms of its thickness, in the structure shown in FIG. 4, for example, it can be found from the comparison of the areas a1 and a2 shown in the upper left corner (here, a2 is the nylon yarn As shown in a1, the front warp FW is an exposed yarn) between the same yarn type yarn crossing portions (between the same yarn type continuous portions) located in the knitting direction D2 of the lace ground. The thickness has been changed. As a result, a gradation can be obtained in the knitting direction in appearance.

  That is, a third fiber and a fourth fiber are provided as a weft or a knitting yarn, and a fiber that is thicker than the fourth fiber is used as the third fiber. By forming a region in which the density of the third fiber is higher than the density of the fourth fiber, a gradation in the knitting direction can be realized in addition to the conventional gradation in the width direction.

  Then, as shown in FIG. 6, for example, in FIG. 1, in the portion B, the color of the nylon liner yarn 9 n shifts from the color development of the nylon liner yarn 9 n to the color of the cationic liner yarn 9 c sequentially, and then in the race ground width direction again. It was possible to return to the color on the cation side.

[Another embodiment]
1. In the above embodiment, specific yarns are used as the bobbin yarn 7, the back warp BW, the front warp FW, the gimp yarn 8, and the liner yarn 9, but the present invention is limited to the selection of the above yarn types. is not.
2. Examples of the fibers having different dyeing properties include the combination of (cation, nylon) described above, the combination of (nylon, viscose rayon), and the combination of (nylon, cotton). . Combinations of these and cotton are also possible, and in addition to a combination of two types of yarns, a configuration in which three or more types differ in dyeability may be employed.
3. Regarding the configuration of the same yarn type yarn transfer section 2, this portion may be formed by a single weft or braided yarn, or may be formed by a plurality of yarns. The same applies to the same yarn type continuous portion 3.
When a plurality of yarns are used, the length in the race width direction is arbitrary.
4. Further, the ratio of the same yarn type yarn transfer section 2 composed of each yarn type can be arbitrarily adjusted with respect to a unit area having a predetermined number of courses. The appearance of the same yarn type yarn transfer section 2 made of another type of yarn is dispersed in the knitting direction of the lace ground. As a result, a texture similar to a gradation can be obtained favorably. Here, if the dispersion is made uniform, a structure in which a change in gradation is hardly noticed can be obtained. Further, in the width direction D1 of the race ground, as shown in the embodiment, if there are four stages (Ze, Zm1, Zm2, Zc), and if there are three or more stages, a race similar to gradation can be obtained. Becomes
5. In the above embodiment, the case of the river lace ground 1 has been described, but the present invention is also applicable to a raschel ground knitted by a raschel warp knitting machine. Regarding the Russell ground, FIG. 7 is a structural diagram corresponding to FIG. 3, and a ground structure is constituted by a chain stitch yarn 71 as a warp and a net yarn (not shown) as a weft. An elastic thread (not shown) may be inserted between the predetermined wale W and the wale W to impart elasticity to the knitted fabric. Then, in a state of being bundled by the above-described chain stitches, a plurality of insertion threads 72 are inserted according to the position and movement of the corresponding reed. (A), (b), (c), and (d) show the selected state of the yarn structure and the yarn type (cation insertion yarn 72c, nylon insertion yarn 72n). As you go to the right, you can see that the density of nylon is increasing. Here, as apparent from the correspondence with FIG. 3, the insertion yarn 72 is an example of a knitting yarn.
6. In the above-described embodiment, for example, a region having a predetermined wale and a predetermined number of courses as shown in FIGS. 3 and 7 has been described as a unit region. It is sufficient that the knitting structure region is basically provided as a unit region with a knitting structure region of 3 wales or more and 3 or more courses. As shown in FIGS. 3 and 7, it is preferable to compare four wales and about 16 courses (16 to 26 courses).

We were able to obtain a technology capable of mass-producing gradation lace with high decorativeness.
Furthermore, by providing gradation in the knitting direction, the value of the race could be significantly increased.
