Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elastic pile warp knitted fabric, and more particularly, to a stretchable pile warp knitted fabric having a hem portion formed by a drawn yarn, and comprising an elastic yarn and an inelastic yarn. The present invention relates to an elastic pile warp knitted fabric composed of yarn. 2. Description of the Related Art Stretch warp knitted fabrics in which an elastic yarn is combined with a non-elastic yarn of a ground structure are often used for clothes such as innerwear such as foundations, sports clothing and outerwear.
The stretchable warp knitted fabric is usually knitted using a tricot knitting machine, a Russell knitting machine or the like. Particularly recently, a hem portion formed by a drawn thread and a body fabric adjacent to the hem portion are knitted. A knitted fabric in which parts are integrally knitted is manufactured. This knitted fabric is easy to sew because the knitted fabric can be divided by the hem, and the inner such as girdle and shorts with the hem at the hem of the product has no seam at the hem and does not affect the outer Therefore, a knitted fabric having the hem portion is used for many products such as an inner. [0003] However, when wearing a product such as a girdle using an elastic warp knitted fabric having such a hem portion, the hem portion shifts due to the bending and stretching of the body such as standing on a chair, and in the case of a girdle, There has been a problem that a displacement phenomenon occurs and discomfort increases. In order to prevent this problem, to strengthen the knitted fabric power in the vicinity of the hem portion and to firmly tighten the body, for example, in a girdle or the like, a method of improving the tightening force of the thigh has been proposed, There was a problem that the displacement could not be completely prevented, and the tightening was too tight to reduce the wearing comfort. In such a stretchable warp knitted fabric having a hem portion,
At present, it has not yet been obtained a product that can suppress the displacement of the hem at the time of wearing without increasing the tightening force and has both a comfortable wearing feeling and a fitting feeling. An object of the present invention is to solve the above-mentioned problems of the prior art and to provide a product manufactured by using an elastic warp knitted fabric composed of a hem portion and a body material portion. Another object of the present invention is to provide a stretchable pile warp knitted fabric that can suppress displacement of a hem portion caused by wearing without increasing tightening force and can provide a comfortable wearing feeling. Means for Solving the Problems In order to solve the above problems, the present inventors have conducted intensive studies on the state of wearing an inner such as a girdle, and as a result, it has been found that the adhesion between the fabric and the body is shifted at the hem. The present inventors have found that the above problem can be achieved by forming a pile on the body material portion in order to improve the adhesion, and arrived at the present invention. The invention claimed in the present application to achieve the above object is as follows. (1) A warp knitted fabric composed of a hem portion and a body material portion,
An elastic pile warp knitted fabric, wherein a pile is formed in the body cloth portion. The stretch pile warp knitted fabric of the present invention is a warp knitted fabric composed of a hem portion and a body cloth portion.
A knitted fabric in which a pile is formed in the body portion. In the present invention, the hem portion refers to an end portion of the cut fabric. A known method can be used for knitting of the hem portion. Generally, a non-elastic yarn thread (chain knitting) is arranged on the elastic yarn insertion structure, and after knitting and dyeing, the non-elastic yarn thread is removed. Is formed to form a hem portion where the knitted fabric is divided in the warp direction. In the present invention, the body portion refers to a warp knitted fabric formed of an elastic yarn and an inelastic yarn and knitted adjacent to the hem portion. The body portion is knitted with a plain or patterned, substantially planar ground-floor-free ground structure, and a pile is formed on the entire surface or a part thereof. [0007] An inelastic thread is used for the pile, and the pile is formed on one or both sides of the body portion. The shape of the pile is such that a loop pile in which the yarn constituting the pile (referred to as a pile yarn) protrudes in a loop shape on the surface of the fabric, or a yarn protruding on the surface of the fabric, in which all or a part of the filament of the yarn is cut by a raising machine or the like. The shape may be any shape such as a cut pile such as a velor tone, lightly brushed, or a mixed state of the loop pile and the cut pile, as long as the pile state is formed by an inelastic thread different from the ground structure. Generally, the formation of a pile on a knitted fabric is performed for the purpose of imparting heat retention and heat storage to the knitted fabric, but the stretchable pile warp knitted fabric of the present invention enhances the adhesion between the fabric and the body when worn. A pile is formed in the body portion of the stretchable warp knitted fabric having a hem portion in order to suppress the displacement of the hem portion. With such a configuration,
The knitted fabric is easy to split and sew, has less effect on outer garments, and has the effect of a stretchable warp knitted fabric with a hem portion with less stitching at the seam, while suppressing the displacement of the hem due to wearing, making it comfortable. A comfortable wearing feeling can be obtained, and the product can be made with less looseness of the sewn portion even when the product is worn. The inelastic yarn used for the ground structure and pile of the warp knitted fabric is not particularly limited, and synthetic fibers such as polyester, nylon and acrylic, and natural fibers such as cotton, wool and hemp can be used. For example, if polyester or nylon is used, inner clothing with good dimensional stability can be obtained,
In order to impart water absorbency or moisture absorbability, fibers such as cotton, cupra, and rayon may be used. Further, by blending, blending, twisting, or knitting on a knitting machine, etc.
More than one kind of yarn may be mixed and used. There is no limitation on the form of the yarn to be used, and a filament yarn, a spun yarn, a modified cross-section yarn, or the like can be used. There is no particular limitation on the thickness of these inelastic yarns, but 20 to 170 dt.
ex is preferably in the range, more preferably 30 to 110d.
tex. In the case of cotton count, it is preferable to use a 120-30S class yarn, more preferably 100S-50S.
Is the use of Further, when a knitted fabric is required to be thin and lightweight, a thin thread should be used as much as possible, and when a strength improvement is required, a thick thread should be used as much as possible. As the elastic yarn used for the ground structure, a yarn having elasticity such as polyurethane or polyetherester can be used. For example, as the polyurethane elastic yarn, a yarn obtained by dry spinning or melt spinning can be used, and there is no particular limitation on the polymer or spinning method. The elastic yarn has an elongation at break of 400% to 1000%, has excellent elasticity, and has a normal processing temperature of 180 in a presetting step during dyeing.
It is preferable not to impair the elasticity in the vicinity of ° C. Further, a yarn provided with functionalities such as antibacterial property, moisture absorption and water absorption to the elastic yarn can be used. The thickness of the elastic yarn is not particularly limited, but is preferably from 10 to 200 dtex, more preferably from 30 to 160 dtex, in order to knit without problems as the elastic yarn forming the knit loop. The stretch pile warp knitted fabric of the present invention can be manufactured by a warp knitting machine such as a Russell warp knitting machine or a tricot warp knitting machine, and not only a plain machine but also a jacquard machine can be used. The gauge of the knitting machine is not particularly limited.
The use of a 6 gauge / inch knitting machine is preferred. Also, an arbitrary organization can be selected as the ground organization of the body material portion, for example, a tricot organization such as half and satin, a Russell organization such as 6 course satin net, twin power, and 4
A reed or a multi-sheet reed can be used. The pile formation site is not particularly limited, but is most easily and preferably formed in a ground structure. Known methods can be used to form the pile. For example, the inelastic yarn is shaken for about 3 to 8 stitches during knitting, and the distance between the wales is shortened in the finished state after the dyeing processing.
A method of embossing a sinker loop of inelastic yarn that has been shaken for about eight stitches to form a pile shape may be used. In this case, the pile yarn may be arranged on the front reed of the warp knitting machine, but it is not always necessary to arrange the pile yarn on the front reed for the purpose of changing the pile shape, etc., and the pile yarn is arranged on the reed inside the front reed. However, it is also possible to arrange another inelastic thread on the front reed. When piles are formed on both sides of the knitted fabric, it is possible to relatively easily form a double-sided pile by increasing the runner length (braid length) of the front reed or the pile yarn arranged inside the front reed. is there. Furthermore, the formation of the double-sided pile is performed by knitting the back reed by placing a pile yarn separately from the front reed or the pile yarn arranged inside the front reed and increasing the runner length of the back reed. By changing the loop structure with the ground structure, it is possible to carry out such a method that the pile yarn is also formed on the technical face side of the fabric.
Further, as a method easily possible with a Russell warp knitting machine, a pile can be formed by warp insertion knitting of an inelastic yarn. [0012] The formation of the pile on the body portion may be formed on the entire surface or a part of the body portion as described above.
An example of a state in which a pile is partially formed is, for example, a case in which a cloth portion having only a ground structure is formed between a hem portion and a pile to form a longitudinal stripe shape. In this case, the width of only the ground structure can be any width. Furthermore, it is also possible to change the power of the elasticity of only the ground structure to provide a power difference from the pile. The power of the body portion of the stretchable pile warp knitted fabric can be set arbitrarily, and the entire surface of the body portion may have the same power, or the power of the knitted fabric end near the hem portion may be stronger than other portions. It is also possible. The stretchable pile warp knitted fabric of the present invention may be used for a cloth piece constituting a product, for example, the entire fabric of shorts, and the stretchable pile warp knitted fabric of the present invention is used for a skirt portion of a foundation such as a girdle. For example, a high-quality product excellent in a feeling of wearing can be obtained even by partial use. EXAMPLES The present invention will be described below in more detail with reference to examples, but the present invention is not limited to these examples. Example 1 Using a 28 gauge / inch 4-reed tricot knitting machine with a device width of 130 inches, each reed, thread type and structure were set as follows. Front reed: Polyester 56dT (detex, the same applies hereinafter) / 30f was used, and the texture was 10/23. First middle reed: The structure was set to 10/01 using 78 dT of polyurethane elastic yarn (trade name: Leica manufactured by Asahi Kasei Corporation). 2nd middle reed: Polyester 56dT /
Tissue was 56/00 using 30f. Back reed: Polyurethane elastic yarn (trade name: Leica manufactured by Asahi Kasei Corporation) 44dT was used, and the texture was set to 22/10. [0014] In addition, the hem portion can be pulled out,
A wale that is drawn so that the second middle reed and the back reed can be pulled out is knitted by a thread drawer, and the drawn thread wale is made of polyester 84dT / 36f from the rear of the knitting machine.
The cheese yarn of the processed yarn was knitted by passing it through the first middle reed, and the knitting of the second middle reed and the back reed was knitted by entangled with a chain knit, which is a polyester thread. The width of the knitted fabric divided by the hem portion was designed to be 45 cm, and each portion was set by the above-described method so that the thread could be pulled out. Furthermore, the knitted fabric without front pile, the first middle reed, and the back reed is knitted without threading the second middle reed outside the hem portion for 3 cm from the hem portion. Designed. The knitted fabric thus knitted is refined, and
Preset at 45 ° C. for 45 seconds. The density setting at the time of presetting was 110 courses / inch and 60 wales / inch, and after presetting, dyeing was performed at 125 ° C. for 30 minutes using a liquid jet dyeing machine. After this, the length and width are 170
The finishing set was performed at 45 ° C. for 45 seconds to produce an elastic pile warp knitted fabric. The obtained stretch pile warp knitted fabric can be divided from the hem part, and by sewing this girdle with the girdle by using it laterally, the rise of the hem when worn is suppressed,
In addition, it became a very high-grade product with little looseness at the hem. Example 2 A 28-gauge / inch 4-reed tricot knitting machine having a device width of 130 inches was used, and each reed, thread type and structure were set as follows. Front reed: Polyester 56dT / 3 as pile yarn
0f was used and the tissue was 10/45. First middle reed: The structure was set to 10/01 using 78 dT of polyurethane elastic yarn (trade name: Leica manufactured by Asahi Kasei Corporation). Second middle reed: The texture was set to 12/00 using 44dT of polyurethane elastic yarn (trade name: Leica manufactured by Asahi Kasei Corporation). Back reed: Polyurethane elastic yarn (trade name: Leica manufactured by Asahi Kasei Corporation) 44dT was used, and the texture was set to 22/10. [0017] In addition, in order to enable the thread to be removed from the hem portion,
A wale that is drawn so that the second middle reed and the back reed can be pulled out is knitted by a thread drawer, and the drawn thread wale is made of polyester 84dT / 36f from the rear of the knitting machine.
The cheese yarn of the processed yarn was knitted by passing it through the first middle reed, and the knitting of the second middle reed and the back reed was knitted by entangled with a chain knit, which is a polyester thread. The width of the knitted fabric divided by the hem portion was designed to be 45 cm, and each portion was set by the above-described method so that the thread could be pulled out. The knitted fabric having a pile on the entire surface knitted in this manner was refined and preset at 190 ° C. for 45 seconds. The density setting at preset is 110 courses / inch, 60
After pre-setting, dyeing was performed at 125 ° C. for 30 minutes using a jet dyeing machine. Furthermore, after this, finish setting is performed at 170 ° C for 45 seconds with the length and width,
An elastic pile warp knitted fabric was produced. The obtained stretch pile warp knitted fabric can be divided from the hem part, and as a result of sewing the shorts using this knitted fabric in the horizontal direction, the rise of the hem at the time of wearing is suppressed, and It became a very low quality product. Comparative Example 1 A pile-free knitted fabric was produced under the same conditions as in Example 1 except that the swing of the second middle reed was changed to 12/00, and a girdle was sewn and worn with this knitted fabric. When the user bends and stretches the body, the hem may shift, resulting in a product with poor wearing feeling. According to the stretch pile warp knitted fabric of the present invention, since the knitted fabric can be divided at the hem portion, it is easy to sew the fabric. Displacement of the portion is suppressed, a comfortable wearing feeling can be obtained, and a product with less loosening of the sewn portion even when the product is worn can be obtained.
