Description

  The present invention is suitable for use in producing clothing that is easy to move while producing sufficient volume in the fabric thickness to provide heat retention and also abundant flexible stretchability (elongation). It relates to stretch fabric that can be made.

  As a circular knitted fabric (tubular fabric) knitted using a double circular knitting machine equipped with a cylinder and a dial, a knitted fabric that is light and has a volume is known (see, for example, Patent Document 1). This known knitted fabric has a single knit (for example, a flat knit) using a cylinder needle when knitting by setting a plurality of yarn feeders in the course direction with the direction of running the yarn (circumferential direction of the cylinder or dial) as the course direction. Knitting), a single knit course with dial needles, and a course with plating knitting while the dial needle side is tucked and the cylinder needle side is knit, and a knitting structure is formed. Yes.

  On the other hand, as other tubular fabrics, knitted fabrics that have been raised to increase heat retention are known (see, for example, Patent Document 2). This known raised knitted fabric also has a single knit course with a cylinder needle, a single knit course with a dial needle, and a dial needle side as a tack when knitting with a plurality of yarn feeders in the course direction. A knitting structure is configured by combining with a knit course on the cylinder side. In the course in which the dial needle side is tack and the cylinder needle side is knit, the needle loop on the cylinder needle side is raised.

Japanese Patent Laid-Open No. 62-141161 JP 2000-256945 A

  None of the known knitted fabrics disclosed in Patent Documents 1 and 2 have a course knitted into a double knit (for example, rib knitting) because they do not place importance on stretchability. It was not enough. Therefore, when these knitted fabrics were used, it was not possible to produce a garment that achieved both a fabric thickness volume feeling and stretchability.

The present invention has been made in view of the above circumstances, and produces clothes that have sufficient stretchability (elongation) while allowing sufficient warmth by generating sufficient volume in the fabric thickness and is easy to move. It is an object of the present invention to provide a ground stretch fabric that can be suitably used for manufacturing a fabric.
Another object of the present invention is to provide a ground stretch fabric having a knitted structure in which inconveniences such as snacking and expansion of fabric fraying due to occurrence of run do not occur even by making the stretch property rich.

In order to achieve the above object, the present invention has taken the following measures.
That is, the ground thickness stretch fabric according to the present invention is a fabric in which the direction of running the yarn at the time of knitting is set as the course direction and a plurality of yarn feeders are provided in the course direction, and is tuck-knitted tack course, It is characterized in that a repeat knitting structure is formed including a plating course in which at least one is made into a double knit by plating knitting of an elastic yarn and an inelastic yarn, and a course having only a single knit is absent.

It is preferable that the tack course is adjacent to the next course of the plating course.
It is preferable that the tack course tack is pulled up with respect to the needle loop of the plating course to form a triple loop.
The plating course is preferably a course in which the inelastic yarn is double knit and the elastic yarn is single knit.

  The next course of the tuck course is provided with a double knit course that is supplied with a long yarn length to form a double knit, and the next course of the double knit course is provided with the plating course adjacent thereto. It should be repeated on the course.

  The fabric thickness stretch fabric according to the present invention produces sufficient volume in the fabric thickness to provide heat retention, while also making flexible stretchability (elongation) abundant and making clothes that are easy to move, etc. Can be preferably used. The ground stretch fabric has a knitting structure that is rich in stretch properties but does not cause inconvenience such as snacking and expansion of fabric fraying due to run.

It is an organization chart showing a 1st embodiment of ground thickness stretch cloth concerning the present invention. It is the stitch figure which showed 1st Embodiment of the ground thickness stretch fabric which concerns on this invention. It is an organization chart showing a second embodiment of the ground stretch fabric according to the present invention. It is the organization chart showing a 3rd embodiment of ground thickness stretch cloth concerning the present invention. It is the organization chart which showed comparative example cloth.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 and 2 show a first embodiment of a ground stretch fabric 1 according to the present invention. The ground thickness stretch fabric 1 according to the first embodiment has a knitting structure having a tack course 3 knitted by tuck and a plating course 5 knitted by plating, and a single knit (for example, flat knitting). There is no course that is organized solely by this.

  In the first embodiment, it is assumed that a double-knit course 4 by a double knit (for example, rib knitting) is added between the tack course 3 and the plating course 5 as a three-part repeat. That is, in the ground stretch fabric 1, a double knit course 4 is arranged adjacent to the next course of the tack course 3, and a plating course 5 is arranged adjacent to the next course of the double knit course 4. The next course after the ting course 5 is a knitting structure in which the tack course 3 is repeatedly arranged adjacently. And the tack of the tack course 3 is pulled up with respect to the needle loop of the plating course 5 to form a triple loop 7 (see FIG. 2).

  The ground thickness stretch fabric 1 having such a knitting structure can be knitted by, for example, a double circular knitting machine including a cylinder and a dial. In the following, the case of knitting using this double circular knitting machine (not shown) will be exemplified, and the direction in which the yarn runs during knitting (circumferential direction of the cylinder or dial) is defined as the course direction, and a plurality of knitting directions are provided in this course direction. It is assumed that the yarn feeder is provided and knitted in a cylindrical shape. In the first embodiment, since three-port repeat is used, the first yarn feeder to the third yarn feeder (shown in order from top to bottom in FIG. 1) are used.

The tack course 3 is a course for mainly giving volume to the fabric thickness. The tack course 3 can be knitted with short fibers such as acrylic rayon.
The double knit course 4 is a course mainly for increasing the stretchability (elongation) of the fabric. Moreover, this double knit course 4 has the effect | action of joining a fabric surface and a fabric back. The double knit course 4 can be variously changed in appearance, pattern, texture (texture), and depending on the case, the degree of heat retention, by appropriately selecting the knitting method and the yarn type to be used. For example, when the double knit course 4 is an all-knit rib knitting (the knitting needle is not mistaken), it can have an appearance and texture that emphasizes a relaxed feeling.

The double knit course 4 can be knitted with a long fiber composite yarn made of nylon and polyester, for example.
In these tack courses 3 and double knit courses 4, the knitted surface on the cylinder needle side is formed as the skin side surface of the garment by subjecting the loop knitted on the cylinder needle side to raising and fluffing. In order to give the garment a relaxed feeling, when knitting the tack course 3 and the double knit course 4, the length of the loop formed is set to be longer than that of the standard double knit knitting. It is good to try to enlarge.

  The plating course 5 is obtained by forming at least one of the elastic yarn 10 and the inelastic yarn 11 into a double knit (rib knitting). In the first embodiment, the elastic yarn 10 is single knit (flat knit) while the inelastic yarn 11 is double knit. Originally, the course used for the plating course 5 is intended to develop the returnability (shrinkability) of the fabric by stretching the elastic yarn 10. Here, the elastic yarn 10 is not limited to being knitted with a single knit, and can be knitted with a double knit or the like. In the first embodiment, a single knit using a dial needle is used, but a single knit using a cylinder needle may be used.

However, as shown by the No. 3 feeder in the reference example of FIG. 5, when the elastic yarn 10 is a single knit course 12 knitted only by a single knit, a so-called yarn jumper 13 (a loop adjacent in the course direction) A portion where one elastic yarn 10 is connected to the loop) appears.
Such a yarn spanning portion 13 is exposed linearly between the ribs on the fabric surface side when the fabric is stretched. In this way, even if the yarn spanning portion 13 is at a very small distance, when the exposed portion is exposed, the exposed portion is easily caught by contact with other objects such as nails of a person who handles the fabric during washing or use. , Snacking (drawing the yarn from the fabric surface and fraying), and severe cases can lead to yarn cutting. Once such snacking or yarn cutting is reached, a run occurs from that point, and there is a risk that the appearance of the fabric surface is very noticeable.

  Therefore, in the ground stretch fabric 1 according to the present invention, as shown in FIG. 1, by performing a plating knitting using the elastic yarn 10 and the non-elastic yarn 11, the yarn crossing portion 13 of the elastic yarn 10 is formed. The knitted structure is reinforced by double knit with inelastic yarn 11. When the non-elastic yarn 11 is knitted into a double knit, the non-elastic yarn 11 has an effect of giving a fabric-thick volume, and the stitches become dense and the knitting structure becomes dense, and as a result, an effect of improving heat retention is obtained. Is preferable. In addition, the double knit portion has the same effect as the double knit course 4 in that the front and back of the fabric are joined.

In this plating course 5, the non-elastic yarn to be double knit can be knitted with long fibers such as nylon. Further, SCY (single covering yarn), DCY (double covering yarn), etc. can be adopted as the elastic yarn used for single knit.
As a result of producing clothing using the ground thickness stretch fabric 1 having the knitting structure of the first embodiment, sufficient stretch is generated in the fabric thickness to provide heat retention, while providing a flexible stretch property (elongation). We were able to complete clothing that was easy to move and abundant.

In addition, even if the fabric is stretched, the yarn crossing portion 13 of the elastic yarn 10 that appears between the ribs is reinforced with the double-knitted inelastic yarn 11 attached thereto. In particular, it can be said that the yarn crossing portion 13 is subjected to positional restraint by the triple loops 7 (see FIG. 2) formed on both sides thereof, and the looseness is limited.
For this reason, the yarn spanning portion 13 of the elastic yarn 10 may lead to snacking or yarn cutting due to contact with the nails of the person handling the ground thickness stretch fabric 1 or other things during washing or use. There was almost nothing. In addition, even if the elastic yarn 10 is caught on the yarn crossing portion 13, the danger that the yarn crossing portion 13 is reinforced and is subjected to positional restraint may lead to snacking as much as possible. It is suppressed.

Therefore, naturally, in the ground stretch fabric 1 according to the present invention, the occurrence of runs caused by snacking and yarn cutting is eliminated, and the fabric surface is hardly derived.
FIG. 3 shows a second embodiment of the ground stretch fabric 1 according to the present invention. The ground thickness stretch fabric 1 of the second embodiment is different from the first embodiment in that not only the non-elastic yarn 11 but also the elastic yarn 10 is double knit in the plating course 5. Other configurations and operational effects are substantially the same as those of the first embodiment.

In the second embodiment, by forming the elastic yarn 10 as a double knit, a knitting structure in which no yarn crossing portion (see reference numeral 13 in FIG. 1) associated with the single knit is generated at all. The effect of preventing the occurrence of cutting is further enhanced. Further, since the elastic yarn 10 is a double knit, it is possible to obtain the advantages of further enhancing the sense of thickness and further improving the heat retaining property.
FIG. 4 shows a third embodiment of the ground stretch fabric 1 according to the present invention. The ground thickness stretch fabric 1 of the third embodiment is the same as the first embodiment in that it is configured as a three-part repeat by the tack course 3, the double knit course 4, and the plating course 5. The relationship between courses is different. That is, in this ground thickness stretch fabric 1, a plating course 5 is disposed adjacent to the next course of the tack course 3, and a double knit course 4 is disposed adjacent to the next course of the plating course 5. The knit course 4 has a knitting structure in which the tack course 3 is repeatedly arranged adjacent to the next course.

By the way, the present invention is not limited to the above-described embodiment, and can be appropriately changed according to the embodiment.
For example, the ground stretch fabric 1 according to the present invention can be knitted by a circular knitting machine equipped with a double cylinder or a flat knitting machine with a two-row needle bed. As is clear from this, the ground stretch fabric 1 according to the present invention is not conditioned to be cylindrical or to undergo a form knitted as a tube, but is knitted as a single flat fabric. It may be done.

The double knit course 4 can be omitted.
It is also possible to provide yarn feeders beyond 3 ports on condition that the course knitted only by single knit is not included, and it is possible to have a repeat structure of 4 or more ports.
In each course of the tack course 3, the double knit course 4, and the plating course 5, the thread type to be used is not particularly limited. For example, a long fiber is used for the tack course 3, or the double knit course 4 is used. Short fibers may be used. It is also possible to employ short fibers for the inelastic yarn 11 that is double knit in the plating course 5. Of course, what is specifically selected as the short fiber or the long fiber is not limited at all. Further, for the elastic yarn 10 to be single knit in the plating course 5, it is possible to adopt bare yarn in addition to SYC and DYC.
