Description

  The present invention relates to a yarn end treatment method for preventing fraying of yarn at the end of a woven fabric and yarn removal.

  In the textile industry, which is a local industry, especially in low-priced products, China and other countries have remarkable labor costs and increased competitiveness for quality improvement. In recent years, bipolarization has been progressing in which low-priced products centering on manufacturing-type retailers and high-end products typified by European and American luxury brands are popular. In addition, due to the improvement of Chinese fabric quality, sewing in China using Chinese fabrics is increasing.

  Under such circumstances, the production volume in Japan's domestic production areas, especially the production volume in Banshu textile production areas, is also decreasing. The history of Banshu weaving includes lappet weaving developed in Taisho 11, swivel weaving developed in 1949, and loop weaving developed in 1964. They have been used as embroidery. Currently, research is being conducted on new sewing products and new uses that are unprecedented in the textile production area using the swivel weaving technique of the Banshu weaving technique.

On the other hand, the yarn end treatment is conventionally performed in order to tension the yarn so that the yarn at the end is not frayed when weaving the fabric. For example, as shown in FIG. 3, the yarn end processing is performed by weaving several warp yarns 1 by plain weaving or kneading in order to tension the weft 2 after weft insertion in the loom. Then, the yarn end Y is cut. Generally, the ear tissue X after weaving is cut and discarded separately from the cloth. In the conventional yarn end treatment, as described above, the yarn end treatment is performed in which the warp yarn is interlaced with the end of the weft yarn to tension the weft yarn, and the ear tissue is cut and discarded after use.
Thus, in the conventional yarn end treatment, the ear tissue is cut and discarded after use. This is uneconomical, especially when expensive yarns are used.

In addition, as a loom for performing yarn end processing, for example, on the opposite weft insertion side of a weft yarn, a pair of upper and lower yarn end processing yarns are drawn from a yarn end processing yarn supply body through a lead to a false twisting device. There is known a yarn end treatment apparatus that twists upper and lower yarn end treated yarns in a false twisting operation in conjunction with a loom and holds a weft end portion that is inserted (patent document 1).
In this way, the yarn end treatment has a different weaving method depending on the type of fabric, and it has been necessary to use a dedicated sewing machine or manually.

  In view of the above situation, the present invention aims to improve the production efficiency of yarn end processing, and to provide a yarn end processing method using swivel weaving with the aim of opening up new uses of swivel weaving. Objective.

The inventor has already succeeded in weaving the wefts along the outline of the shape of the garment in the process of weaving the fabric, focusing on how to use the wefts peculiar to the region-specific swivel weaving technique. . As a result, it is possible to realize non-sewing of the finished fabric such as clothing by cutting the outer shape line so as not to cut the weft of the woven fabric.
This time, the present invention was completed with the idea that wefts can be woven together along the outer shape of the garment in the process of weaving the fabric, and this can be applied to ear tissue.

That is, the yarn end treatment method of the present invention uses Suwaiberu loom weaving Suwaiberu yarn ends of warp as the weft one, to form a selvage as part of the fabric, Ya fray the edge of the fabric This is to prevent the thread from coming off.
By forming an ear tissue using a swivel loom that weaves swivel yarn , yarn end treatment can be performed simultaneously in the process of weaving the fabric. Thereby, the ear tissue can be formed as a part of the fabric, not the ear tissue that is cut and discarded after use, and the yarn can be effectively used.

Here, the swivel yarn is driven in less than the number of times the weft of the fabric is driven, and the weft of the fabric is driven while the driving direction is reversed . See write out the Suwaiberu yarn weft implantation times less, by weft is driven while the direction, which are discharged is reversed, there is ensured to ensure prevention omission fraying and yarn of the yarn end of the fabric, the efficiency of the weaving process Can be achieved.

According to the yarn end treatment method of the present invention, by forming the ear tissue with the swivel yarn, the yarn end treatment can be performed simultaneously in the process of weaving the fabric, and the efficiency of the yarn end treatment can be improved. There is an effect.
In addition, since the ear tissue can be formed as a part of the woven fabric, the yarn can be effectively used and the economy can be improved.

Model of formation of ear tissue by swivel weave of Example 1 Enlarged photo of the fabric with the yarn end treatment of Example 1 Explanatory drawing of conventional yarn end processing

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the scope of the present invention is not limited to the following examples and illustrated examples, and many changes or modifications are possible.

FIG. 1 shows an ear tissue formation model by swivel weaving of Example 1.
FIG. 1 (1) shows the front surface, and (2) shows the back surface. In FIG. 1, the warp yarns are tapped 12 rows 3, 5, 7, 9, B, D, F, H, J, L, N, P, and the weft yarns are rows 1, 3, 5, 7, 9 , B, D, F, H, J, L, N, P, R 14 are hit.
The swivel yarn forming the ear tissue passes through the surface in the meridian direction from the matrix (0, G) to the matrix (2, G), and then warp once from the matrix (2, G) to the matrix (2, 2). It is entangled in the matrix (2, 9) and passes through the back surface in the weft direction. The swivel yarn passes through the surface in the warp direction from the matrix (2, 2) to the matrix (8, 2), and then the swivel yarn is warp once from the matrix (8, 2) to the matrix (8, G). Are interlaced with the matrix (8, 9) and pass through the back surface in the weft direction. The swivel yarn passes through the surface in the longitudinal direction from the matrix (8, G) to the matrix (E, G), and then the warp and the matrix (E) once from the matrix (E, G) to the matrix (E, 2). , 9) and entangled in the weft direction.
By repeating these steps, the swivel yarn forms ear tissue.

  FIG. 2 is an enlarged photograph of the fabric subjected to the yarn end treatment of Example 1 described above. The swivel weave can be used to prevent fraying of the ears and thread removal. In FIG. 2, 1 is a warp thread, 2 is a weft thread, 3 is a swivel thread, and 5 is an ear thread. It should be noted that the exposed portion of the swivel thread 3 is indicated by hatching because it is difficult to distinguish it in the photograph.
