Description

  The present invention relates to an elastic warp knitted fabric having a concavo-convex pattern that can be suitably used for underwear or outer garments.

  Warp knitted fabrics such as elastic knitted fabrics are often used in women's underwear such as girdles, bras, and shorts, and sportswear such as body suits, swimwear, and leotards.

  The elastic warp knitted fabric is made of a satin knitting with chain knitting yarn and insertion yarn, plain cord knitting, denbi knitting, tulle knitting or mesh knitting knitting structure, and polyurethane fiber etc. By knitting by inserting spandex yarn or other elastic yarn, or knitting by forming a stitch, the entire knitted fabric is given elasticity, and a normal lace pattern or the like is integrally formed with the handle. In general, a so-called jacquard lace pattern is integrally formed by changing the thick ground, thin ground, hole or the like by the jacquard guide rod.

  A stretchable warp knitted fabric such as a conventional jacquard knitted fabric has a stretch yarn inserted into the entire knitted fabric, and the entire knitted fabric has substantially uniform stretch power and stretchability. When wearing clothes such as girdle or bra made using, the fit is good to some extent, but it does not have a partly large stretch power or stretchability, and the body shape correction function according to the body shape is sufficient It was not obtained.

  For this reason, conventionally, another stretch fabric has been sewn as a dressing cloth or the like in order to exert a large body stretching power and stretchability and exert a body shape correction function. However, clothing made with a different stretch fabric as a garment and partially increased or decreased in stretch power has a difference in thickness at the boundary between the area where the garment is present and the area where it is not present. It appeared, and it was visible from the outside of the outerwear, and there was a problem that the appearance was remarkably lowered. In addition, there is a problem that the stitched portion becomes hard and feels unpleasant, giving the wearer discomfort.

For this reason, in recent years, it has been proposed to partially increase the stretching power and stretchability of stretchable fabrics by warp knitting without using a patch.
For example, in Patent Document 1, by switching the non-stretchable yarn and two or more kinds of stretchable yarns, a portion having a high stretchability and a portion having a low stretchability are provided as a switching unit. It has been proposed to knit continuously so as not to have.

  However, in the case of the above proposal, the high stretch portion and the low stretch portion are linear in the knitting direction, that is, in the case of warp knitting, the stitch direction (warp direction), and the body shape correction function is also linear. However, it was limited to that which was not able to exhibit sufficient functions.

  Further, in Patent Document 2, in a knitted fabric such as a lace knitted fabric that is warp knitted with a non-stretchable yarn and a stretchable yarn, a knitting structure that appears on the front side of the ground knitting in response to a request for strength of stretching power It is proposed to form a pattern shape in which a portion having a strong tension (stretching power) is formed due to a change in tissue, and the portion having a strong stretching power is curved.

  Further, in Patent Document 3, in a stretchable warp knitted fabric in which a stretchable yarn is inserted or knitted in a ground knitting structure by warp knitting, the stretch power and stretchability of the yarn in the knitted fabric weft direction, etc. The elastic warp knitted fabric provided with a plurality of regions having different elastic power and / or extensibility by appropriately changing at least one of the elastic power and extensibility by a combination of the change in the characteristics and the change in the knitting structure Has been proposed.

  Unlike the conventional stretch warp knitted fabric in which the knitting structure is changed to change the stretch power and / or stretchability, the present invention inserts a handle yarn having a different thickness and / or stretchability with a handle. It is an object of the present invention to provide a stretchable warp knitted fabric having a concavo-convex pattern provided with a plurality of regions in which stretch power and / or stretchability is changed by forming unevenness changes.

As a result of intensive studies to solve the above problems, the present inventors have made the present invention.
That is, the present invention is as follows.

  1. A warp knitted fabric knitted by a warp knitting machine provided with a handle, wherein a pattern is formed by inserting pattern yarns having different thicknesses and / or extensibility in the handle, and the expansion / contraction power and / or A stretch warp knitted fabric having a concavo-convex pattern, wherein a plurality of regions having different stretch properties are provided.

  2. The stretch warp knitted fabric having a concavo-convex pattern as described in 1 above, wherein the pattern yarn is one or more selected from nylon yarn, polyester yarn, rayon yarn, cotton yarn and polyurethane yarn.

  The stretch warp knitted fabric having the uneven pattern of the present invention has improved fit to the body as compared with the conventional stretch warp knitted fabric, and can reliably and sufficiently exhibit the compensation function according to the body shape. In addition, it is easy to set the change area of the stretch power and / or stretchability, the strength of the stretch power, the magnitude of the stretch ability, and the change, and the change can be diversified.

The present invention will be described in detail below.
The conventional stretch warp knitted fabric depends on the change of the knitting structure in order to change the function relating to the stretch power and / or stretchability, but unlike that, the stretch warp knitted fabric of the present invention is a handle, A plurality of regions in which the stretching power and / or stretchability is changed by inserting a pattern yarn having different thicknesses and / or stretchability to form unevenness changes are provided.

  The stretch warp knitted fabric having a concavo-convex pattern according to the present invention uses a warp knitting machine in which the handle is placed in front of the jacquard fold, inserts pattern yarns having different thicknesses and properties, on the front and back of the knitted fabric The knitted fabric is provided with a plurality of regions in which the expansion / contraction power and / or the stretchability are changed by forming the unevenness change.

  In the elastic warp knitted fabric having a concavo-convex pattern according to the present invention, the conventional elastic properties expressed in a plane are expressed in that the portions with different functions relating to the elastic power and / or extensibility are expressed three-dimensionally. It is clearly different from warp knitted fabric.

  In the elastic warp knitted fabric having a concavo-convex pattern of the present invention, the concave and convex portions formed on the front and back of the knitted fabric are preferably arranged on the strips, respectively, and the width and interval of the concave and convex portions are as follows: It can be appropriately changed depending on the use and purpose of the knitted fabric, for example, the body shape and the correction function. In addition, the change in stretch power and / or stretchability can be achieved by changing the type, characteristics, thickness, number, or combination of the handle yarns to be inserted, the width and spacing of the formed concave and convex portions, etc. It can diversify by selecting suitably according to it.

  In the present invention, the pattern yarn inserted by the handle is not particularly limited, but may be one or more selected from nylon yarn, polyester yarn, rayon yarn, cotton yarn and polyurethane yarn. preferable.

  In the present invention, among the plurality of regions having different stretching power and / or stretchability, a region having a large stretching power is set so as to exhibit a compensation function according to the body shape when used for clothing. It is also possible to set it easily. Thus, the body shape correcting function can be satisfactorily exhibited in use in clothing.

  In addition, among a plurality of regions having different stretching power and / or stretchability, a region having a large stretchability is set as a part corresponding to the bulge portion of the body shape in the form when used for clothing. You can also. Thereby, the adaptability with respect to the body shape at the time of using for clothing can be improved.

  For example, it is possible to change the stretch power and / or stretchability by knitting the pattern yarn by changing at least one of the thickness and the number of yarns in a required region in the knitted fabric weft direction. Further, for example, a thick thread having a large expansion / contraction power is used as a pattern thread in a portion where expansion / contraction power is required, and a thin thread having a small expansion / contraction power is used as a pattern thread in a portion that does not require a large expansion / contraction power.

  Thereby, the expansion / contraction power can be changed at a required region in the knitted fabric weft direction, and a portion with strong and weak expansion power can be created. Moreover, even if the yarns have the same thickness, the expansion / contraction power can be changed by changing the number of yarns to be inserted. Further, by combining the thickness of the yarn and the number of yarns, it is possible to make a difference in the expansion / contraction power in at least one direction of the process, and various expansion / contraction powers can be obtained. Similarly, the stretchability of the knitted fabric can be changed by using stretchable yarns having different stretchability.

  In order to knit the elastic warp knitted fabric having the uneven pattern of the present invention, a known warp knitting machine equipped with a jacquard fold can be used. Preferably, the handle fold is arranged in front of the jacquard fold. Using a warp knitting machine, by selecting the type, thickness, number of pattern yarns to be inserted, and the width and spacing of the concave and convex portions to be formed, the strength of the stretching power and the size of the stretch Since it can be changed, the fit to the body and the correction function according to the body shape are effectively exhibited.
