Description

The present invention relates to a warp knitted fabric in which cellulose fibers and elastic yarns are interwoven.

Conventionally, when clothing is made from fabric, the fabric cutting portion causes fraying and curling of threads, so the fabric cutting portion is sewn to suppress these. However, since the thickness of the sewn part increases, when an inner that has been cut by sewing is worn, the unevenness of the sewn part affects the appearance and impairs the appearance, and the sewn part is pressed by the outer garment. There is a problem that it causes a decrease in feeling. Therefore, for example, clothing made using a knitted fabric that does not require sewing of the cut portion as shown in Patent Document 1 below is also commercially available.

However, it is said that the fabric stretches by about 50% when the girdle is worn, and when a knitted fabric with a double denbi structure that can be cut off is used for clothing that is expected to be worn in the stretched state, the fabric does not stretch easily. It is hard to wear and feels bad to wear.
As a knitted fabric that does not require sewing of the cut portion knitted by the double atlas structure, a knitted fabric produced by using the double atlas structure as described in Patent Document 2 below has also been proposed. The texture is prone to loop distortion and the aesthetics of the knitted fabric is prone to deterioration. It is possible to improve the quality of the knitted fabric by increasing the density of the stitches, but in that case, there is a problem that sufficient elongation cannot be obtained as an inner such as a girdle that is expected to be worn in an extended state.

Most of the knitted fabrics that can be cut off are knitted from synthetic fibers and elastic yarns, but knitted fabrics consisting only of synthetic fibers and elastic yarns are inferior in moisture absorption and desorption and cold sensitivity, so they are elastic with synthetic fibers. The bleedable knitted fabric knitted from yarn tends to feel sticky or stuffy due to sweating or insensitive evaporation when worn in a hot environment or the like. Therefore, a method such as using a composite yarn is adopted with the aim of reducing stickiness and stuffiness by knitting cellulose, but the quality of the knitted fabric tends to deteriorate, and the difficulty of adjusting the tension at the time of knitting is high. From the viewpoint of knitted fabric quality and knitting property, it is desirable to knit with a warp knitting machine with 3 reeds. Is difficult to work, and curling cannot be prevented even if the heat setting conditions are strengthened. As described above, it has been difficult to obtain a warp knitted fabric which has high elongation, can be cut off, and is hard to curl by cross-knitting cellulose fibers and elastic yarns.

Japanese Patent No. 3672920 Japanese Unexamined Patent Publication No. 2007-131956

In view of the current state of the art, the problem to be solved by the present invention is that the warp knitted fabric in which cellulose fibers and elastic yarns are cross-knitted has high elongation, and fraying and curling of the knitted fabric cut portion are not suppressed. It is to provide a warp knitted fabric that can be cut off and does not curl even when the knitted fabric is stretched.

As a result of diligent studies and experiments to solve the above problems, the present inventors have conducted a tricot knitting machine with three reeds, in which the first reed is a synthetic fiber, the second reed is a cellulose fiber, and the third reed is elastic. We have found that the above problems can be achieved by limiting the structure of the synthetic fiber and the elastic yarn in the warp knitted fabric in which the cellulose is knitted by arranging the yarn, and have completed the present invention. It is a thing.

That is, the present invention is as follows.
[1] A warp knitted fabric composed of a synthetic fiber of a first reed, a cellulose fiber of a second reed, and an elastic yarn of a third reed, which is composed of a complete eight-course structure, and the first reed and the first reed. The structure of the three reeds forms a two-course stitch by swinging one stitch alternately left and right, then folds back, forms a stitch by swinging one stitch continuously for two courses in the folding direction, then folds back again, alternating left and right 1 After forming two courses of stitches by needle swing, the stitches are folded back, and two courses are continuously formed by one stitch swing in the folding direction, and the knitted fabric passes through the knitted fabric cut in the knitted fabric warp direction. A warp knitted fabric characterized in that the curl of the knitted fabric cut portion when extended by 50% in the direction is 60 ° or less.
[2] The warp knitted fabric according to the above [1], wherein the stitch density in the warp knitted fabric direction is 120 to 150 courses / inch.

The warp knitted fabric according to the present invention is knitted with cellulose fibers and elastic yarns, which can be cut without fraying or curling of the knitted fabric cut portion, have high elongation, and do not curl even when the knitted fabric is stretched. It is a warp knitted fabric.

It is the structure of the synthetic fiber and the elastic yarn in Comparative Example 4.

Hereinafter, embodiments of the present invention will be described in detail.
The warp knitted fabric of the present embodiment is a warp knitted fabric knitted by two types of inelastic yarns of a synthetic fiber of a first reed, a cellulose fiber of a second reed, and an elastic yarn of a third reed, and is a first reed. And the structure of the third reed form a stitch of 2 courses by swinging 1 stitch alternately left and right, then folding back, forming a stitch by swinging 1 stitch continuously for 2 courses in the folding direction, folding back, and then alternating left and right. It is a 1-complete 8-course structure characterized in that a 2-course stitch is formed by swinging 1 stitch, then folded back, and 2 courses are continuously formed by swinging 1 stitch in the folding direction.

The organization of the present embodiment will be specifically described with reference to FIG. When forming a two-course stitch by swinging one stitch alternately to the left and right, the knitting may be started from either the right or the left. For example, when the stitch is formed alternately from the left to the left and right, the stitch is folded back later. The direction is to the left, and the structure is such that stitches are formed continuously for two courses by swinging one stitch to the left. After that, it is folded back to the right, the stitch is knitted by swinging one stitch to the right, and then the stitch is knitted by swinging one stitch to the left. Next, after knitting two courses of stitches alternately on the left and right, the stitches are folded back and one stitch is swung to the right to form two consecutive courses of stitches.

For the stitch structure of the synthetic fiber and the elastic yarn, the closing stitch and the opening stitch can be arbitrarily selected.

One complete course in the present embodiment consists of the number of courses required for the unit of the repeating organization to be organized. For example, the front reed is a code organization as shown in FIG. 2, and the middle reed is a denby organization as shown in FIG. When the back reed is the organization shown in FIG. 1, the front reed and the middle reed form one complete organization in two courses, and the back reed forms one complete organization in eight courses.

The structure of the synthetic fiber of the first reed and the elastic thread of the third reed of the warp knitted fabric in the present embodiment must be the structure of the above 1 complete 8 courses, but the knitting start point is arbitrary for each of the synthetic fiber and the elastic thread. Can be selected. For example, as shown in FIG. 4, the knitting start point of the elastic yarn can be set to a structure in which the knitting start point of the elastic yarn is delayed by 3 courses with respect to the knitting start point of the synthetic fiber shown in FIG. Is also possible.

The structure of the cellulose fiber of the second reed is not particularly limited and may be any structure. In addition to tissues such as denby and cord, full insertion tissue and chain knitting can also be used. More preferably, by forming a structure that combines looping and insertion as shown in Fig. 5 on 11/12/11/10 // and Fig. 6 on 10/22 //, it is possible to create a structure that is thin and has excellent elongation in a hot environment. It becomes a knitted fabric of cellulose mixed knitting suitable for use. Of course, it may be an organization of 1 complete 8 courses as shown in FIG. The stitch structure of the cellulose fiber can be arbitrarily selected as a closed stitch or an open stitch.

The positional relationship between the synthetic fiber of the first reed, the cellulose fiber of the second reed, and the elastic thread of the third reed in the present embodiment is arbitrary. In other words, it is possible to use cellulose fibers for the front reed, synthetic fibers for the middle reed, and elastic threads for the back reed, as well as synthetic fibers for the front reed, elastic threads for the middle reed, and cellulose fibers for the back reed. Is.
Normally, when cellulose fibers are interwoven, if the cellulose fibers are exposed on the surface of the knitted fabric, the cold feeling such as contact cold feeling and sweat absorption will be excellent, but due to the dyeing process, wearing as clothes, washing, etc. In addition to the abrasion of the cellulose fibers, if the color is dark, the fastness to wet friction is lowered, and the color may be transferred to the outer or the like, which is likely to cause practical problems. Therefore, it is preferable that the front reed is a synthetic fiber, the middle reed is a cellulosic fiber, and the back reed is an elastic yarn so that the cellulose fiber is not exposed on the surface of the knitted fabric as much as possible.

Normally, in order to make a knitted fabric that can be cut off, the temperature is raised and the setting time is lengthened when the knitted fabric is a cross-knitted fabric made of synthetic fibers such as nylon and polyester, which is easily heat-set, and elastic yarn. By strengthening the heat setting conditions, the synthetic fibers are heat-fixed to suppress curling and fraying, and many of the bleachable garments known so far use this technique.

However, since the knitted fabric consisting of only synthetic fibers and elastic yarns is inferior in moisture absorption and desorption and cold sensitivity, the bleedable knitted fabrics knitted from synthetic fibers and elastic yarns are sweaty and insensitive when worn in a hot environment. It was easy to feel stickiness and stuffiness due to evaporation. Therefore, a method such as using a composite yarn is adopted with the aim of reducing stickiness and stuffiness by knitting cellulose, but the quality of the knitted fabric tends to deteriorate, and the difficulty of adjusting the tension at the time of knitting is high. From the viewpoint of knitted fabric quality and knitting property, it is desirable to knit with a warp knitting machine with 3 reeds. It is difficult to obtain a warp knitted fabric in which cellulose fibers and elastic yarns are interwoven and can be cut off, because curl generation cannot be prevented even if the heat setting conditions are strengthened.

Therefore, the present inventors diligently studied and analyzed and examined a knitted fabric structure in which the warp knitted fabric does not curl on the sinker loop surface, which is particularly important for garment products. By doing so, we will develop a warp knitted fabric that has bleeding properties while interlacing cellulose fibers and has an elongation that can be used for clothing such as girdles that are expected to be worn in a stretched state. It has arrived.

The reason why the tissue of this embodiment has an influence on the suppression of transcurl during elongation is as follows.
An example is a case where the front reed is knitted as a synthetic fiber, the middle reed is knitted as a cellulose fiber, and the back reed is knitted as an elastic fiber.
When the synthetic fiber, the elastic thread, and the cellulose fiber intersect on the sinker loop surface of the knitted fabric, the sinker loop of the middle reed is located in a curved state straddling the sinker loop of the elastic fiber of the back reed, and further, the sinker loop of the middle reed is located. The synthetic fibers of the front reed will be located on the middle reed, and the curvature of the synthetic fibers of the front reed will be considerably larger than the curved surface of the cellulose fibers.
Normally, when the knitted fabric is extended in the warp direction, the sinker loop tends to be perpendicular to the width direction of the knitted fabric, and as the knitted fabric is extended, the sinker loop tends to become linear. Therefore, when the knitted fabric is stretched, the force for straightening the sinker loop acts strongly on the synthetic fiber having the largest curvature, and the sinker loop at the knitted fabric cutting portion becomes linear. At this time, in the knitted fabric cutting portion, the sinker loop of the synthetic fiber that was curved over the elastic yarn rises on the sinker loop surface with the straddling elastic yarn as a fulcrum, so that the knitted fabric is curled. It ends up. When the knitted fabric is stretched, the curvature of the cellulose fibers also tends to be linear, but since the curvature is smaller than that of the synthetic fibers, the contribution rate of the knitted fabric to the curl is considerably small.

That is, reducing the curvature of the synthetic fiber is effective in suppressing warp curl during elongation, and the synthetic fiber and the elastic thread of the front reed have the same structure, and the intersection of the sinker loop of the synthetic fiber and the sinker loop of the elastic thread. By controlling the above, it is possible to suppress the curl of the knitted fabric by reducing the curvature of the sinker loop of the synthetic fiber.
In the warp knitted fabric of the present embodiment, the curl angle at the time of extension under the curl measurement conditions described later is 60 ° or less, preferably 30 ° or less. When a knitted fabric with a curl of more than 60 ° when stretched is cut off and used as an inner, the curled and warped part when wearing the outer garment is sandwiched between the outer garment and the skin, causing unevenness and impairing the aesthetic appearance. The unevenness puts pressure on the skin, which impairs the feeling of wearing. On the other hand, if the curl angle at the time of extension is 60 ° or less, it will not be inserted between the outer garment and the skin when used with the uncut inner, so it will not affect the appearance and will not impair the wearing feeling. ..

The reason why the tissue of the present embodiment is excellent in elongation while suppressing the suppression of transcurl during elongation is as follows.
The warp knitted fabric in the present embodiment is a warp knitted fabric composed of a 1-complete 8-course structure knitted with synthetic fibers of the first reed, cellulose fibers of the second reed, and elastic threads of the third reed. The tissues of the 1st reed and the 3rd reed form a stitch of 2 courses by swinging 1 stitch alternately on the left and right, then fold back, and after forming a stitch by swinging 1 stitch continuously for 2 courses in the folding direction, fold back again. It is a warp knitted fabric characterized in that two courses of stitches are formed by swinging one stitch alternately on the left and right, then folded back, and two courses are continuously formed by swinging one stitch in the folding direction.
That is, the textures of the synthetic fiber of the first reed and the elastic yarn of the third reed are the structure of alternately knitting the two-course stitches on the left and right (part A in FIG. 1), and the two-course stitches are knitted in the same direction to the right or left. It is composed of tissues in which the tissues to be formed are alternately repeated (site B in FIG. 1), and the tissues having different elongations are repeated every two courses.

The relationship of elongation in the warp knitted fabric of this embodiment is site B> site A. As described above, when the knitted fabric is extended in the warp direction, the sinker loop tends to be perpendicular to the width direction of the knitted fabric. Will be large. In the knitted fabric, the part B knits the stitches in the same direction for two consecutive courses, so that the sinker loops are knitted in the same direction. Therefore, when there is no extension, the angle of the sinker loop is almost parallel to the width of the knitted fabric. At the time of extension, the sinker loops at an angle close to parallel tend to be vertical, so that the amount of movement of the sinker loops is large and the elongation is large with respect to the portion A. On the other hand, in the tissue having a small elongation (site A), the sinker loop is difficult to move, so that transcurl is unlikely to occur.
That is, in the present embodiment, a specific structure is obtained by combining a portion B having a high elongation and a portion A having a low elongation, and the intersection of the sinker loops of the synthetic fiber and the elastic yarn is set as a specific range to form the sinker loop of the synthetic fiber. By reducing the curvature, the knitted fabric has excellent elongation while suppressing warp curl during elongation.

As shown in FIG. 12, when three or more courses are knitted alternately on the left and right, the elongation becomes small, which makes it unsuitable for use in clothing that is expected to be worn in the extended state.
When three or more courses are continuously organized to the right or left, the part where the amount of movement of the sinker loop is large continues. The tissue with a large amount of movement means that the sinker loop is easy to move, and the curved sinker loop tends to be straight when stretched, and when it straddles the elastic thread, it becomes the sinker loop surface with the straddling elastic thread as a fulcrum. It is easy to stand up and warp curl is likely to occur. Further, since the amount of movement of the sinker loop is large, the stitches are easily distorted, the shape and size of the stitches are easily deformed, and the aesthetics of the knitted fabric are deteriorated. If the shape and size of the stitches are broken, the surface of the knitted fabric becomes rough, which makes it easier to feel the roughness, and it is not suitable for use as an inner that comes into direct contact with the skin.

In the warp knitted fabric of the present embodiment, it is preferable that the intersection of the sinker loop of the synthetic fiber and the elastic yarn is 25% or less in the structure 1 complete 8 courses of the synthetic fiber. The intersection of the sinker loop of the synthetic fiber and the elastic yarn means the point where the synthetic fiber and the elastic yarn intersect between the wells of the knitted fabric. For example, when the synthetic fiber is used for the front reed and the elastic yarn is used for the back reed, the synthetic yarn is synthesized. The structure of the fibers is 12/10/21/23/12/23/12/10 // shown in FIG. 1, and the structure of the elastic yarn of the back reed is shown in FIG. 4, and the knitting of the synthetic fibers shown in FIG. 1 is started. If the knitting start point is delayed by 3 courses with respect to the point, the synthetic fiber sinker loop and the elastic yarn sinker loop are in one complete course. Since the number of courses and the number of sinker loops are the same, eight sinker loops are formed respectively. In this case, as shown in FIG. 9, six places are formed without intersecting the synthetic fiber a and the elastic thread b, and the intersections where the structure of the synthetic fiber a and the sinker loop of the structure b of the elastic thread intersect. c is in two places.
Since the warp knitted fabric of the present embodiment has a structure of 1 complete 8 courses for both synthetic fibers and elastic yarns, it may be calculated with 8 fibers, and the following formula (1):
Ratio of intersections = (intersections: 2 places) ÷ (number of sinker loops: 8) x 100
Therefore, the ratio of intersections is calculated to be 25%.

In FIG. 9, in order to explain the intersection of curls in detail, the threads arranged on the adjacent courses are ignored, and only one synthetic fiber and one elastic thread are shown. In the example of FIG. 9, the thread is actually passed through the adjacent courses, and even in that case, the intersections of the synthetic fiber a and the elastic thread b are two in the eight courses as shown in FIG. Become.

The warp knitted fabric of the present embodiment has a stitch density of 120 courses to 150 courses / inch, so that the elongation in the warp direction is 80% or more, and the warp knitted fabric does not warp even when stretched by 50% and is in a stretched state. The knitted fabric can be suitable for clothing that is supposed to be worn. If it is coarser than 120 courses / inch, the amount of movement of the sinker loop during extension becomes large, so that the effect of suppressing transcurl during extension becomes slightly small. On the other hand, the elongation of the warp knitted fabric of the present embodiment is preferably 70% or more, more preferably 80% or more, but when the density is higher than 150 courses / inch, it is difficult to obtain sufficient elongation for wearing.

The structures of the first and third reeds of the present embodiment are all characterized by swinging one stitch, but this is due to the lengthening of the sinker loop when cutting by swinging two or more stitches to form a stitch. This is because the fraying of the needle becomes large, which makes it unsuitable for an inner used as a bleed. In addition, since the basis weight is large and the thickness is also large, it is not suitable for a thin inner that is supposed to be worn in a hot environment.

The synthetic fiber in the present embodiment is different from the elastic yarn, and refers to a fiber having a maximum elongation of less than 100% in the present specification. The synthetic fiber is not particularly limited, and examples thereof include polyester fibers such as polyester and polytrimethylene terephthalate, and synthetic fibers such as polyamide fibers and polypropylene, and these bright yarns, semi-dull yarns, full-dull yarns, and the like can be arbitrarily selected. As for the cross-sectional shape of the fiber, it is possible to use a fiber having an arbitrary cross-sectional shape such as a round shape, an elliptical shape, a W shape, a cocoon shape, and a hollow yarn. Etc. can be used.

The cellulose fibers are not particularly limited, and are, for example, regenerated cellulose fibers such as rayon, cupra, and bamboo fibers, and short fibers of natural cellulose fibers such as cotton, and the thickness of the fibers is 30 to 90 dtex (decitex: the following). Threads with the same symbol) can be used.

The elastic yarn in the present embodiment is different from the synthetic fiber, and refers to a fiber having a maximum elongation of 100% or more in the present specification. The elastic yarn is not particularly limited, and examples thereof include polyurethane-based and polyether ester-based elastic yarns. For example, the polyurethane-based elastic yarn is not particularly limited to a polymer or a spinning method, which can be used by dry spinning or melt spinning. The elastic yarn is excellent in elasticity, and it is preferable that the elasticity is not impaired at a normal treatment temperature of around 180 ° C. in the presetting process during dyeing. In addition, elastic yarns with high settability, deodorant properties, and antibacterial properties can be used by adding a special polymer or powder. A fiber having a fineness of 10 to 80 dt can be used, and it is preferable to use an elastic yarn having a fineness of 15 to 60 dt, which facilitates knitted fabric production.

In the warp knitted fabric of the present embodiment, the elastic yarn can contain an inorganic substance, and the knitted fabric can be made in consideration of the performance of the contained inorganic substance.
In the warp knitted fabric of the present embodiment, cellulose fibers can be woven with an arbitrary structure. Therefore, it is comfortable without feeling sticky or stuffy when sweating, and it can be made into clothes that can be cut off without sewing the edges of the garment. A clothing product with an excellent feeling can be obtained.

In the present embodiment, it is preferable that the basis weight of the knitted fabric is 110~250g / m ^2, more preferably 120~210g / m ^2. If the basis weight becomes too large, the thickness of the fabric increases, which makes it easy to get stuffy and has a great influence on the appearance when worn, which causes a problem in actual wearing. If the basis weight is too small, the burst strength will decrease, which is also a problem in actual wearing.

The warp knitted fabric in the present embodiment can be knitted by a tricot or Russell warp knitting machine, and can be knitted by these single warp knitting machines. The gauge of the knitting machine can be arbitrarily selected, but it is preferable to use a knitting machine of about 24 to 40 gauge, and if the gauge is coarse, the aesthetics of the knitted fabric is not good, and if the gauge of the knitting machine is higher than 40, As the stitches become smaller, the knitted fabric density increases and the elasticity becomes poor, which makes the knitted fabric unsuitable for use in clothing worn in the stretched state. More preferred.

As a dyeing finish method for the warp knitted fabric of the present embodiment, a normal dyeing finish process can be used, the dyeing conditions are set according to the fiber material used, and the dyeing machine used is also a liquid flow dyeing machine, a wins dyeing machine, and a paddle dyeing machine. Any use such as a machine is possible, and a processing agent that improves water absorption and flexibility can be used.

The warp knitted fabric of the present embodiment is sewn to clothing such as innerwear and sportswear in addition to the girdle worn in a stretched state, so that it does not feel sticky or stuffy due to sweating even in a hot environment and stretches when worn. Even so, the clothing can be made so that the cut portion does not curl.
If the garment on which the cellulose mixed knitted fabric of the present embodiment is arranged is worn, it is comfortable without feeling sticky or stuffy when sweating, and the garment can be cut off without sewing the end of the garment. , It does not curl even when stretched, and there is no unevenness in the sewn part, so a clothing product with excellent wearing feeling can be obtained.

Hereinafter, the present invention will be specifically described with reference to Examples. Of course, the present invention is not limited to these examples. The evaluation in the examples was performed as follows.

(1) Elongation in the warp direction Bend in the weft direction of the knitted fabric, and hold both ends of the knitted fabric at intervals of 10 cm in the warp direction of the knitted fabric. In this state, the knitted fabric is stretched in the warp direction, and the length in the long side direction of the test piece when the knitted fabric is fully stretched is measured.
(Measurement length cm-10 cm) ÷ (10 cm) x 100 = Elongation (%)

(4) Elongation warp curl The curl in the knitted fabric warp direction when the knitted fabric cut portion cut in the knitted fabric warp direction was grasped and extended by 50% in the warp direction was measured. A rectangular knitted fabric cut to 10 cm in the warp knitted fabric direction and 2.5 cm in the knitted fabric weft direction was used as a test piece and placed on a horizontal desk. Next, both ends in the warp direction are gripped by fingers and stretched by 50%, and the curl angle generated in the warp knitted fabric warp direction at the time of stretching is defined as a straight line (2) tangent to the horizontal knitted fabric (1) as shown in FIG. The curl angle (d) at which the straight line (3) in contact with the end of the knitted fabric at the time of 50% elongation intersects was measured.
