Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a circular knitted fabric containing elastic yarn, which is formed by incorporating elastic yarn into a stockinette fabric of ground yarn in order to increase the degree of stretch of the knitted fabric; Specifically, the present invention relates to a method of incorporating an elastic yarn into a stockinette knitted fabric, in other words, the knitting structure thereof.

(Prior art) When cutting the opening of clothing made of circular knitted fabric with elastic threads,
The knitting structure to make it difficult to pull out the elastic thread was developed in 1974.
It is disclosed in Japanese Patent No. 55213.

This is shown in FIG. In the figure, 1 is a ground yarn made of ordinary yarn, 2 is an elastic yarn incorporated into the knitted fabric of the ground yarn,
4 indicates a cutting line. In a predetermined portion 3 around the cutting line 4, as shown in the figure, the ground yarn type and the elastic yarn 2 are alternately knitted. In other words, the ground yarn 1 and the elastic yarn 2 are intertwined. In addition, in other parts, the elastic thread 2 is the base thread 1.
It is threaded through the stitches of the stockinette fabric. According to the knitting structure of the predetermined portion 3, the knitting structure is cut at the cutting line 4.
・It is also difficult to remove the elastic thread 2. Therefore, even if the cut edge is sewn onto another knitted fabric or woven fabric after cutting, the elasticity of the knitted structure is not lost.

(Problems to be Solved by the Invention) However, in the above conventional example, if there is a defect in sewing the cut edge, when the knitted fabric is repeatedly expanded and contracted, the shrinkage force of the elastic thread 2 causes the At the cut edge, the elastic yarn 2 forming the same stitch as the ground thread 1 is pulled to the side where it is threaded through the ground thread 2, and as a result,
The disadvantage was that the stitches at the cut edges were broken and ultimately holes were formed in the knitted fabric.

An object of the present invention is to provide a knitting structure that solves the above-mentioned problems of conventional circular knitted fabrics containing elastic yarns.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the circular knitted fabric containing elastic yarn according to the present invention has the following configuration.

In other words, in a circular knitted fabric with elastic yarns that incorporates elastic yarns to impart elasticity to a stockinette fabric formed from ground yarns, the stitches in a predetermined portion of the circular knitted fabric are made of ground yarns and elastic yarns. are superimposed. Here, "overlapped" refers to a state in which the base yarn and the elastic yarn are doubled to form one stitch (hereinafter, such a knitting structure is referred to as a layered knitting structure). Also, the predetermined part is
When cutting a knitted fabric as in the conventional example, this term refers to the cut portion, and in the case of other purposes, it refers to the point where the purpose is to be achieved.

(Operations and Effects) According to the circular knitted fabric with elastic thread according to the present invention, when the cut edge is sewn to another knitted fabric or fabric after cutting at a predetermined portion, even if the cut edge is sewn to another knitted fabric or fabric, even if the stitching is defective, Even if the elastic yarn is pulled out, the stitches formed only by the base yarn will not be destroyed. Therefore, according to the circular knitted fabric with elastic threads according to the present invention, the drawback of holes being formed in the knitted fabric due to poor sewing of the cut edges, which was observed in conventional circular knitted fabrics with elastic threads, can be eliminated. be.

The present invention produces not only the above-mentioned functions and effects, but also the following excellent functions and effects.

That is, by forming the above-mentioned overlapping knitting structure in a predetermined portion of a normal stockinette knitted fabric, a pattern consisting of a combination of a normal stockinette knitted fabric and a predetermined portion can be formed. For example, in a normal stockinette knitted fabric, when the elastic yarn is passed through the ground yarn, the predetermined portion has a larger shrinkage force in the longitudinal direction of the stitches than in the normal stockinette knitted fabric. , a curly pattern is formed here.

Furthermore, by knitting the above-mentioned overlapped structure in a predetermined portion of a normal stockinette knitted fabric, it is possible to exert an effect of strongly attracting the surrounding knitted fabric by utilizing the contractility of this overlapped structure. This effect can be effectively utilized when obtaining a desired shape for a specific product knitted with a circular knitted fabric.

(Example) An example of the present invention will be described with reference to FIGS. 1 to 6.

First Embodiment A first embodiment of the present invention will be described with reference to FIGS. 1 and 2.

In this example, when a circular knitted fabric A containing elastic yarn as shown in FIG. Then, the part along the cutting line 4 is defined as a predetermined part 3, and the predetermined part 3
This fabric has a layered knitting structure that is a feature of the present invention. FIG. 2 is an enlarged view showing the knitting structure of the part B surrounded by the dotted line in FIG. 1. As shown in FIG.
In the predetermined portion 3 immediately on both sides of a4, the ground yarn 1 and the elastic yarn 2 are overlapped at every interval in the lateral direction of the stitch to form a stitch, and between these double stitches, the elastic yarn 2 is passed through the base thread I. Further, in the other portion 5 outside the predetermined portion 3, there is no double stitch as described above, and the elastic yarn 2 is simply passed through the stitch of the ground yarn 1.

According to such a knitting structure, after cutting the main knitted fabric at the cutting line 4, the cut edge is sewn to another knitted fabric or fabric, and as a result, the stitching is defective and the elastic thread 2 is Even if the predetermined portion 3 is removed, the ground thread 1 still forms a stitch in the predetermined portion 3, so the knitting structure is not completely destroyed and therefore no holes are formed.

11 A second embodiment of the present invention will be described with reference to FIGS. 3 and 4.

The third tooth is part C of the circular knitted fabric containing elastic yarn according to this example.
It is a two-dimensional representation of In this example,
As shown in Fig. 3, rectangular predetermined portions 3 are arranged at equal intervals in the vertical and horizontal directions of the knitted fabric, and one predetermined portion 3 consists of four predetermined portions adjacent to it in the diagonal direction. Located in the center of 3. FIG. 4 is an enlarged view showing the knitting structure of the part surrounded by the dotted line in FIG. 3. As shown in FIG. 4, in the predetermined portion 3, the base yarn 1 and the elastic yarn 2 are doubled at every other stitch in the lateral direction to form a stitch, and between these double stitches, Elastic thread 2 is base thread 1
The stitches are passed through. In addition, in the other part 5 outside the predetermined part, the elastic yarn 2 is simply passed through the stitches formed by the ground yarn 1.

In such a knitted fabric, the shrinkage force in the longitudinal direction of the stitches in the predetermined portion 3 is greater than that in the other portions 5, so that crimp occurs in the predetermined portion 3. Therefore, when looking at the entire main knitted fabric, curly patterns can be observed here and there.

As described above, the layered knitting structure, which is a feature of the present invention, is also effective in giving the knitted fabric a desired curly pattern.

Third Embodiment A third embodiment of the present invention will be described with reference to FIGS. 5 and 6.

In this embodiment, the layered knitting structure, which is a feature of the present invention, is applied to a girdle 6 as shown in FIG. The girdle 6 has both left and right parts 1. II is knitted separately using a circular knitting machine, cut along the cutting line 4, and then the left and right portions 1. II are sewn together and molded. In this embodiment, as shown in FIG. 5, the predetermined portions 3 are arranged near both sides of the cutting line 4 and in a band-shaped portion corresponding to the ventral lower abdomen, and the two predetermined portions 3 are arranged in the horizontal direction of the stitches. In the other parts 5, the elastic yarn is simply passed through the stitches made by the base yarn. The overlapping knitting structure applied to the two predetermined portions 3 produces the following effects.

In other words, even if there is poor stitching at the cut edge as described in the first embodiment, the layered knitting structure located near both sides of the cutting line 4 will not be destroyed by the contraction force of the elastic thread. . Therefore, even if the girdle 6 is repeatedly expanded and contracted, there will be no holes in the sewn portion.

In addition, the layered knitting tissue located in the band-shaped part corresponding to the ventral lower abdomen has a larger contraction force in the longitudinal direction of the stitches than other parts 5 around it, and therefore the other parts 5 around it,
Pull in the lengthwise direction of the stitch.

As a result, as shown in FIG.
The entire body is shaped to better fit the human body. FIG. 6 shows a girdle 6 to be formed when the double knitting structure is arranged near both sides of the cutting line 4 but not in the band-shaped part corresponding to the ventral lower abdomen.
It shows. In this case, as is clear from the figure, there is no constriction line corresponding to the boundary between the abdomen and the legs, and it can also be seen that it does not fit the human body very well compared to FIG. 5. In this way, the layered knitting structure, which is a feature of the present invention, can be arranged in a predetermined portion to form a knitted fabric into a desired shape.
