Description

[Detailed Description of the Invention] This invention particularly relates to narrow ribbons and similar tapes used for wear.

Ribbons generally have ears on both sides to make them look beautiful and increase their commercial value. In particular, narrow ribbons for decoration are desired to have edges with a well-balanced finish and a beautiful finish in order to enhance their decorative value. For this purpose, conventional methods have been to directly weave the fabric into a narrow woven fabric with a predetermined width, and the warp yarns at the selvedges have a thickness different from that of the ground warp, or have different yarns or yarns of different colors, or have a texture different from the fabric. The ears are made to stand out.

However, in this case, since the ribbons are woven directly into narrow ribbons using a narrow loom, preparation of the warp yarns for weaving the selvedges, construction of the weave, etc. are time-consuming, making mass production impossible. Therefore, it was considered and implemented to provide a middle selvage part on a wide woven fabric and cut it to make multiple narrow woven fabrics, as in the case of ordinary narrow woven fabrics, but in this case, the threads at the cut point of the middle selvage part were It is necessary to create a heddle structure to prevent it from unraveling, and a separate middle ear device must be installed for this purpose. Threading the thread through the heddles, etc. is complicated, resulting in high equipment costs, and a decline in work efficiency is unavoidable. However, the selvedges formed by cutting were not completely prevented from becoming unraveled, and the appearance was not very good.

This invention is an attempt to improve and eliminate the above-mentioned drawbacks of the conventional methods, and the object is to provide a narrow ribbon that can be easily obtained from a wide woven fabric and has a good-looking selvedge. It is.

The following is a description of an embodiment of the configuration of this invention shown in the drawings.

What is shown in FIG. 2 is a wide woven fabric a before obtaining a narrow ribbon, which is woven by arranging a plurality of middle ear portions 1 at intervals of a desired ribbon width as shown in the drawing. This wide fabric a is woven into a plain weave structure using warp yarns 2, weft yarns 3, a fabric portion 1' and a middle ear portion 1, using threads made of thermoplastic fibers such as polyamide fibers. The warp yarns 2a of the middle ear portion 1 are thicker than the warp yarns 2 of the ground portion 1', and four yarns are arranged. After weaving, a heated thin plate or drawer is guided in the center of the middle ear part 1, for example. As a result, the middle ear part is made by partially melting the warp threads and the weft threads and cutting them at the center, and the melted threads are fused at the cut edges on both sides. In this way, the wide woven fabric is divided into a plurality of narrow woven fabrics, each of which is cut and fused to form a plurality of narrow woven fabrics with ears on both sides of the middle selvage. This narrow woven fabric was a desired narrow ribbon, and as shown in Fig. 1, a linear fused portion 4 was formed at the side edge, and a plain weave structure was formed using thick yarns in the same way as the fabric portion 1'. It has ears 1a on both sides. As a result, the edge portion 1a of the narrow ribbon b is fused and does not become unraveled at all, and has a beautiful appearance due to the linear appearance of the fused portion 4 and the plain weave structure made of thick yarns.

In the above example, the warp threads of the middle ear part are thicker than the warp threads of the fabric part, and the plain weave selvage is the same as the fabric structure, but this middle ear part has a normal pillow selvage, Other ear tissues such as ridged ears, nanako ears, and twill ears may also be used. These selvage structures can be formed with approximately the same amount of effort as plain weave selvages, and the resulting ribbon has a beautiful appearance with an even better texture due to the selvage portions that are fused to the fabric and a different tissue. In addition, the middle selvage is not only determined by the thickness or structure of the yarn, but also by making the constituting warp threads different from the ground warp yarns, so that the selvage part can be made to have a luster different from the ground part through post-processing etc. Alternatively, it can be of a different hue, thereby further enhancing the aesthetic appearance.

As explained above, this invention uses threads made of thermoplastic synthetic fibers for the warp and weft yarns, provides a plurality of middle ear parts, and connects the warp threads of the middle ear parts to the warp threads of the fabric part. A plurality of thick yarns are arranged and woven into a wide width. After weaving, linear heating is applied in the longitudinal direction to the center of the middle ear, and when the warp and weft yarns in this area are melted, the middle ear Since some yarns are cut and fused between thick threads, there is no loosening of the threads at all due to the fusion of the threads at the selvage, and this fused portion appears linearly on the selvage side. Together with the structure of the middle ear, it presents a beautiful appearance and increases its commercial value as a narrow ribbon for decoration. Although the narrow ribbon of the present invention tends to harden and harden into a rabbit-like thread, there is no risk of this happening because thick threads are woven around the edges, and because it can be obtained by melting and cutting a wide woven fabric to a predetermined width, The middle selvage part to be melted and cut does not need to be made into a woven fabric, which requires a separate device, and can be made of ordinary plain weave selvage, pillow selvage, etc., so wide fabrics can be easily woven and mass production is possible. be.
