Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a woven fabric that uses foil yarn and has a good texture and excellent design effect.

Conventionally, when forming a pattern using foil yarn, a pattern weaving device such as a jiya guard or a dobby is usually used, and ground weft and ground warp threads are woven together with the foil thread, so the pattern part made of foil thread is divided into two parts. It became layered or triple-layered, stiff and uncomfortable to the skin. Separately, foil threads are sometimes used in thin fabrics, but in this case the foil threads are only woven into a portion of the weft or warp threads, and the design effect is poor.

The present invention provides a method for manufacturing a thin woven fabric having a pattern made of foil threads with excellent design effects at low cost and with good workability without using a pattern weaving device or patterns.

The method of the present invention involves continuously feeding a foil sheet having an arbitrary pattern on at least one side to a warping machine equipped with a cutting device and a detour device, cutting the foil sheet to form foil threads, and The foil thread is passed through a detour device and wound onto a beam with the pattern position partially shifted, and then used as warp threads to produce a woven fabric.

The foil yarn may be manufactured according to the ordinary manufacturing method of flat foil yarn, for example, as described in Japanese Patent Publication No. 56-41712 and Japanese Patent Application Laid-Open No.
A laminated sheet, paper, film, or a laminate thereof having a thin metal layer obtained by the method described in Publication No. 56-118916 or other method, and cutting a foil sheet with an appropriate pattern provided by coating with paint, dyeing, plating, etc. However, in the method of the present invention, immediately after cutting the foil sheet, different tensions are applied to the foil threads using a detour device, as shown in the later examples. It is preferable to produce a foil yarn using a foil sheet made of a laminate having the following properties. In addition,
It is necessary that the foil sheet has an arbitrary pattern, but the size and shape of this pattern are not particularly limited.

In the present invention, a foil sheet is cut to form a group of foil yarns having a pattern similar to the foil sheet, and this foil yarn is passed through a detour device such as a corrugated roller and wound around a beam with partial shifts in the length direction. If the pattern of the foil sheet is partially shifted on the beam, for example if it is a horizontal striped pattern, then it is wound up as a group of foil threads that are transformed into a checkerboard pattern, an arrow pattern, a pot sagging pattern, etc., and these are used as warp threads. In particular, deformed patterns such as checkerboard patterns created by foil threads can be reproduced as they are on woven fabrics.

Therefore, in the present invention, a wide variety of patterns can be produced by simply manufacturing a foil sheet with a pattern, passing it through a warping machine equipped with a cutting device and a detour device, and winding it into a beam by adjusting the position of the foil thread. The texture can be vividly and easily expressed on woven fabric. Furthermore, since it is not necessary to use the fabric as the ground weft or ground warp to create a pattern during weaving, it is possible to produce a woven fabric with a good texture.

In addition, in the present invention, when winding the foil yarn around the beam, it may be wound through an underlay sheet, such as a long film or a piece of paperboard, and by doing so, it is possible to manufacture a woven fabric of higher quality. It becomes possible.

Next, embodiments of the present invention will be described according to the drawings.

Example 1 A laminated sheet consisting of film 1, adhesive 2, and metal layer 3 was manufactured by the transfer method described in Japanese Patent Publication No. 56-41712, and then yellow and a small amount of red dye were mixed with epoxy resin. The colored coating liquid 4 was applied in horizontal stripes at intervals of 50 mm, baked and dried, and then the film 1 was attached again via the adhesive 2 to obtain the foil sheet 5 shown in FIG. 1A.

The foil sheet 5 is passed through the warping machine shown in FIG. 2, which has a slitter 6 and a corrugated roller-type detour device 7, and the slitter 6 cuts it into foil threads with a width of 0.3 mm. 8 were wound onto the winding beam 9 with a difference of 2 mm between each yarn and a deviation of 50 mm between every 25 yarns in an arrow pattern (Fig. 3A). Among the 1,800 ground warp threads, foil threads 8 were weaved for every second thread to obtain a fabric with an arrow patterned pattern of gold and silver. When this was degreased and refined, it became a very soft and beautiful dress fabric.

Example 2 A metal layer 3 was formed by depositing silver on a release sheet,
The colored paint 4 is applied to the surface of the metal layer 3 in horizontal stripes at 10 mm intervals, and after baking and drying, the film 1 is attached via the adhesive 2, and then the release sheet is peeled off to expose the exposed metal layer 3. Then, the colored paint 4 is again applied in horizontal stripes to correspond to the striped pattern on the back side, baked and dried, and then the film 1 is attached with adhesive 2.
The foil sheet 5 shown in FIG. 1B was obtained.

This foil sheet 5 is passed through the warping machine shown in FIG.
The foil threads were cut into 900 foil threads with a width of 0.1 mm, and the foil threads were divided into foil threads that ran perpendicularly every 60 threads and foil threads that detoured by 100 mm, and were wound onto a winding beam 9 (Fig. 3B).
This foil yarn was arranged and weaved every second of the 1800 ground warp yarns, and the fabric was weaved in accordance with a conventional method to obtain a fabric with a gold and silver checkered pattern. When it is degreased and dyed on bone, it always becomes a luxurious dress material.

Example 3 Polyethylene terephthalate film #6 (6
μ thickness), use two-component polyurethane paint to remove clouds in pink and light blue 4a and 4b.
After painting at 300mm intervals, baking and drying, apply polyethylene terephthalate film using adhesive.
#6 was attached to obtain the foil sheet shown in FIG. 1C.

This foil sheet is passed through the warping machine shown in Fig. 2 (however, a needle-and-rat type was used as the detour device 7), and
The foil thread 8 was wound so as to form a drooping pattern as shown in Figure C. This foil thread is organized into a reed of 1800 ground warp threads,
By weaving it, we obtained a beautiful dress material with a potted pattern and a blurred effect.
