Description

  The present invention relates to a stretch warp knitted fabric knitted by using a combination of an inelastic yarn and an elastic yarn, and has a mesh-like air permeability and a large stretchability in the horizontal direction, particularly in an uncut state. It is intended to be used on clothing without cleaning up.

  Fabrics that are highly breathable and excellent in stretch properties are used in clothing applications that fit the body of sports, innerwear, and the like, especially during the summer sweat. As such a material, there has been proposed an elastic knitted fabric that quickly absorbs and diffuses sweat in order to enhance comfort during wearing (see Patent Document 1). However, this elastic knitted fabric is excellent in water-absorbing and quick-drying properties, but there is a problem that fraying occurs when it is used for a part of clothing without being trimmed in a state of being cut.

  Moreover, as seen in Patent Document 2, it is possible to cut out any design shape by knitting a molten elastic yarn and leave it without having to fold the sleeve end or hem end of the garment. A knitted fabric that does not occur has also been proposed. This knitted fabric is a double tricot in which two folds are used as the knitting structure and each fold is always moved in the opposite direction for each course and the knitting yarn is supplied symmetrically. The elastic yarn is easily heat-bonded to the knitting yarn. Is used to melt or bond the elastic yarns together to make it difficult to unravel the hem ends.

  However, this knitted fabric is prone to curl when stretched in the vertical direction, so that there is a problem that the hem is wound. In addition, this knitted structure has a problem of poor stretchability. In addition, the elastic yarn that overlaps behind the inelastic yarn is likely to be cut and so-called pinholes are easily generated. Furthermore, problems such as elastic yarn coming out on the surface side, uneven dyeing, and so-called eye-opening are likely to occur.

  In addition, warp knitting using elastic yarn and inelastic yarn, and a 1 × 1 tricot knitting in which elastic yarn and inelastic yarn are accompanied to prevent fraying has been proposed (see Patent Document 3). However, in the 1 × 1 tricot, since the knitted fabric has a dense structure, the air permeability is low, and when the 1 × 1 tricot is pulled in the horizontal direction, a run is easily generated, and there is a disadvantage that tearing from the end of the knitting is low. .

  The present invention was made in order to eliminate the shortcomings of the warp knitted fabric used in such a conventional hem end cut specification, has a large stretch, fits comfortably on the body, and has an air permeability. It aims to provide a comfortable stretch warp knitted fabric which is high in ventilation and high in ventilation.

  As a result of intensive studies to achieve the above object, the present inventor has made the knitted structure a specific combination structure using Denby and chain knitting, thereby suppressing the occurrence of run, improving tearing, and cutting. It has been found that the knitted fabric is hard to become hot even if left on, and curling is further suppressed. Moreover, by using this combination structure, the eyes became mesh-like, and good breathability was obtained as a comfortable summer apparel.

The present invention has been completed from the above viewpoint, and has the following (1) to (6).
(1) A warp knitted fabric knitted with two or more ridges, in which an inelastic yarn is disposed on one heel, an elastic yarn is disposed on another heel, and both the inelastic yarn and the elastic yarn are denby. A stretch warp knitted fabric having a structure in which chain stitches and chain stitches are alternately connected, and inelastic and elastic yarns are accompanied.
(2) The stretch warp knitted fabric according to (1), wherein at least one of the inelastic yarn and the elastic yarn is knitted by at least a closed stitch.
(3) The stretch warp knitted fabric according to (1), wherein the non-elastic yarn is knitted by a closed stitch and the elastic yarn is knitted by an open stitch.
(4) The non-elastic yarn runner is larger than the elastic yarn runner, the non-elastic yarn runner is 80 to 150 cm / rack, and the elastic yarn runner is 50 to 120 cm / rack. The stretch warp knitted fabric according to any one of (1) to (3).
(5) The stretch warp knitted fabric according to any one of (1) to (4), wherein the air permeability is 50 cc / cm ² / sec or more.
(6) The stretch warp knitted fabric according to any one of (1) to (5), wherein the stretch warp knitted fabric is used for a part or all of clothing without being trimmed.

  The stretch warp knitted fabric of the present invention has a specific knitting structure using denby and chain knitting, which suppresses the occurrence of run, improves tearing, and prevents the occurrence of fraying and curling even if it is not cut. Play. In addition, due to the specific knitting structure, the mesh surface is mesh-like, and it has excellent ventilation and breathability and can fit comfortably on the body.

1 shows a basic knitting structure of a stretch warp knitted fabric of the present invention. The knitting structure of the stretchable warp knitted fabric of the present invention in which both the non-elastic yarn and the elastic yarn are knitted by the closed stitches is shown. 1 shows a knitted structure of a stretch warp knitted fabric of the present invention in which an inelastic yarn is knitted with an opening and an elastic yarn is knitted with a closing eye. The knitting structure of the elastic warp knitted fabric of the present invention in which the non-elastic yarn is knitted and the elastic yarn is knitted by a mixture of open and closed stitches is shown. The knitting structure of the elastic warp knitted fabric of the present invention knitted by inserting the non-elastic yarn into the ground structure having the non-elastic yarn closed and the elastic yarn open is shown. The non-elastic yarn and the elastic yarn both show a knitted structure of a stretchable warp knitted fabric knitted with a different direction Denby structure of a closed line. The knitting structure of a stretchable warp knitted fabric knitted in the same direction Denby structure where the inelastic yarn is closed and the elastic yarn is opened is shown. The sample collection method for evaluating the external appearance and curl property of the fabric after washing of the stretch warp knitted fabric of the present invention is shown.

  The warp knitted fabric of the present invention is knitted with two or more ridges, an inelastic yarn is disposed on one heel, and an elastic yarn is disposed on another heel. When a warp knitted fabric is knitted with a single kite, the number of yarns that are entangled with each other decreases, so that it is easy to tear and the fabric strength becomes weak, which is not preferable. Generally, when these elastic warp knitted fabrics are knitted, a Russell knitting machine or a tricot knitting machine is used. In this case, 2 sheets are the mainstream. Therefore, it is preferable that the number of ridges is knitted within 4 sheets, more preferably within 3 sheets, and most preferably 2 sheets.

  The warp knitted fabric of the present invention is characterized in that both the inelastic yarn and the elastic yarn are composed of a structure in which denby and chain knitting are alternately connected, and the inelastic yarn and the elastic yarn are accompanied. By making both non-elastic and elastic yarns into a denby structure, the sinker loop can be shortened to the shortest and vertical elongation can be obtained. It is. However, in the case of only the Denby structure, a run is likely to occur from the end of the knitting, and the stitches are clogged, so that there is a drawback that air permeability is lost. Therefore, in the present invention, by forming a structure in which the denby structure and the chain knitting are alternately connected, the movement of the yarn is changed at the chain knitting portion, so that the run hardly occurs, and as a result, the tear strength can be improved. Is possible. Moreover, since a mesh is formed in the chain stitch, it is possible to improve air permeability.

  In the warp knitted fabric of the present invention, by causing the inelastic yarn and the elastic yarn to accompany, the inelastic yarn and the elastic yarn do not cross each other, so that the ear curl is less likely to be stretched in the course direction. Entering the lower eye makes it possible to improve the quality because the elastic yarn is less likely to be exposed from the fabric surface.

  As a basic knitting form of the warp knitted fabric of the present invention, a knitted structure (mesh tone denby) in which single denby and chain knitting are alternately connected is shown in FIG. The warp knitted fabric of the present invention is mainly formed by combining the knitting forms shown in FIG. For example, two closed eyes and two open eyes may be alternately arranged. When the mesh-type denby structure is such that the elastic yarn is accompanied by the inelastic yarn, the stretchability is high and the air permeability can be increased.

  In the warp knitted fabric of the present invention, it is preferable to select a combination in which at least one of an inelastic yarn and an elastic yarn accompanying each knitting needle as a knitting yarn is closed. The reason for closing at least one of the accompanying non-elastic yarn and elastic yarn is that closing the loop increases the number of yarn crossing points at the point where the loop is formed, and has the effect of preventing fraying. It is.

  Examples of the warp knitted fabric of the present invention include elastic warp knitted fabric (see FIG. 2) in which both inelastic yarns and elastic yarns are knitted by closed eyes, and inelastic yarns are elastic by open stitches. Elastic warp knitted fabric in which the yarn is knitted by the closed stitch (see FIG. 3), Elastic warp knitted fabric in which the inelastic yarn is knitted by the closed stitch, and the elastic yarn is knitted by a mixture of the open and closed stitches ( 4), and a stretch warp knitted fabric (see FIG. 5) knitted by inserting an inelastic yarn into a ground structure composed of an inelastic yarn and an elastic yarn. These are practically superior. Yes.

  In the warp knitted fabric of the present invention, when chain knit is continuously formed, it is preferably within 5 loops, more preferably 2 or 3 loops. If it exceeds 5 loops, the air permeability is improved, but the mesh portion becomes large, so that the bursting strength tends to deteriorate. Also when forming a denby structure continuously, it is preferably within 5 loops. If it exceeds 5 loops, the air permeability tends to deteriorate.

  As the inelastic yarn used for the warp knitted fabric of the present invention, synthetic fibers such as nylon and polyester, semi-synthetic fibers such as rayon, natural fibers such as silk and cotton, and filament yarns can be used. Spinned yarns can also be used. Among these, nylon having high water absorption is preferable as the knitted fabric for innerwear.

  The elastic yarn used for the warp knitted fabric of the present invention is not particularly limited as long as it has the function, and uses polyurethane elastic yarn, polyether ester elastic yarn, polytrimethylene terephthalate fiber, polybutylene terephthalate fiber. can do. In general, polyurethane elastic yarns widely used and coated elastic yarns are suitable.

  The fineness of the knitting yarn of the warp knitted fabric of the present invention is appropriately selected depending on the clothing using the knitted fabric and the site to be used. When used in women's underwear, the fineness of the elastic yarn is generally in the range of 22 to 470 dtex, preferably 22 to 156 dtex, more preferably 22 to 78 dtex, and the fineness of the inelastic yarn is preferably 17 to 156 dtex, Preferably it is the range of 22-78 dtex.

  In addition, the warp knitted fabric of the present invention can be knitted integrally with a knitted fabric portion in which tightening power is reinforced by using an elastic yarn having a fineness higher than that of other portions as a knitting yarn. Such knitting is useful for the purpose of sewing women's underwear and girdles that partially require a tightening power enhancement part, and also helps to reduce the sewing cost. Further, an elastic yarn or an inelastic yarn is further inserted into the warp knitted fabric of the present invention, and the fineness and the density of the inserted yarn are adjusted as appropriate to knit a knitted fabric having a required elongation and expansion power, Stability can be improved. For example, the touch to the skin can be improved by using an appropriate natural fiber as an insertion thread on the back surface. Moreover, you may give fashionability by inserting a pattern yarn suitably.

  When knitting the warp knitted fabric of the present invention, it is preferable to fabricate the fabric into a narrow width of 40 wales or more per inch, preferably around 60 wales, and to increase the ratio of the horizontal stretch of the knitted fabric. The upper limit is about 100 wales. Specifically, for example, when using a 130-inch raschel knitting machine and knitting with a total number of 3600, the finishing width is about 160 cm in a general knitted fabric, but in the present invention the width is about 130 cm. It is preferable to finish. However, this does not apply when cellulose yarn or cotton yarn is knitted into the inelastic yarn. When the fineness of the elastic yarn is large, particularly when it is 130 dtex or more, the number of wales may be about 60 wales per inch, the total number may be 3600, and the finished width may be processed to about 150 cm.

  In the warp knitted fabric of the present invention, it is preferable that the inelastic yarn runner is made larger than the elastic yarn runner to be unbalanced. Thereby, moderate expansion-contraction to a horizontal direction can be provided. Moreover, it is preferable to make the elastic yarn runner about 50 to 95% with respect to the inelastic yarn runner. More preferably, it is good to set to 75 to 90%. If it is less than 50%, the tension of the elastic yarn is excessively increased and thread breakage is induced by knitting, and if it exceeds 95%, the tension of the elastic yarn becomes too loose and the fabric surface tends to deteriorate. Specifically, the inelastic yarn runner is knitted to 80 to 150 cm / rack, preferably 110 to 130 cm / rack, and the elastic yarn runner to 50 to 120 cm / rack, preferably 75 to 100 cm / rack. Is preferred.

The basis weight of the warp knitted fabric of the present invention is preferably in the range generally used for inner and sports materials, preferably 100 to 300 g / m ² , more preferably 130 to 250 g / m ² . If the basis weight is less than 100 g / m ² , the fabric is easily torn, and if it exceeds 300 g / m ² , the fabric is too heavy and uncomfortable.

  The warp knitted fabric of the present invention can be knitted by a known means by appropriately selecting a Raschel knitting machine, a Jacquard Raschel knitting machine, a tricot knitting machine or the like according to a required knitting structure or the like. In addition to conventionally known means, for example, a recently developed double raschel machine with a piezo jacquard may be used.

  The knitting gauge is usually preferably from 24 to 44 gauge, more preferably from 28 to 36 gauge. Less than 24 gauge is not preferable because the eyes become too rough and the surface becomes worse. On the other hand, if it exceeds 44 gauge, it cannot be knitted unless an extremely thin thread is used, and as a result, the bursting strength tends to deteriorate.

  When dyeing the warp knitted fabric of the present invention, general processing conditions may be adopted as a knitted fabric mixed with spandex, and the temperature of a dry heat set such as a preset is set for the purpose of improving the fraying prevention effect. You may go higher. This temperature depends on the shape of the apparatus, the presetting time, the heat setting time, the type of material, the thickness of the knitted fabric, etc., but at a temperature not lower than 160 ° C., preferably not lower than 170 ° C. In order to obtain the above-mentioned effect more reliably, pre-setting and / or heat-setting within the range of 180 ° C. to 195 ° C. will soften part of the knitted fabric and lightly fuse it to stabilize the shape of the knitted fabric. It ’s hard to fray. When pre-setting and heat setting are performed at the above temperature, the processing time is about 20 to 180 seconds, preferably about 30 to 120 seconds.

  The warp knitted fabric of the present invention can be subjected to various post-processing as necessary to increase added value. For example, a required pattern may be given by printing, hot embossing, or punching, or a mold may be given by molding for use in a brassiere cup or the like. Furthermore, the third fiber is mixed by means of blending, knit, etc., and after the knitting, the third fiber is partially removed by chemical printing etc. to give a pattern, so-called opal processing is applied, and a beautiful knitted pattern It may be ground.

  Next, the effects of the warp knitted fabric of the present invention will be specifically described using Examples and Comparative Examples, but the present invention is not limited to these. In addition, the evaluation method of the characteristic value employ | adopted in this specification is shown below.
