Patterned fabric and a method for the production thereof
a technology of patterned fabric and woven fabric, which is applied in the direction of pattern making devices, textiles and papermaking, looms, etc., can solve the problems of inability to reproduce the nuances generated in the color breakdown used today, the quality difference between, and consequently the woven illustration, so as to achieve the effect of reducing the amount of outlay necessary for this purpose, simplifying the setting up of the weaving program, and advantageously simplifying the design of the insertion devi

Benefits of technology
"The invention is about improving patterned fabrics, specifically Jacquard fabrics, by using an irregular weave and weaving the fabric with warp threads and weft threads. The weft threads can cross over the warp threads, creating a color dot or a color mix effect. The invention also includes a method for producing the patterned fabric using a file format and a weaving program. The technical effects of the invention include improved reproduction of the illustration in the fabric, better overall impression, and simplified setting up of the weaving program."
Problems solved by technology
Although a large number of color shades can be generated, the nuances generated in the color breakdown used today are not always reproduced by means of the repeat repetition.
Quality differences between the illustration to be woven and the woven illustration consequently occur, this being a disadvantage.
To be precise, it became clear that, in woven colored illustrations in the colors yellow, red and blue, the color mix is faulty, that is to say they do not have all the colored shades of the model.
However, such corrections can be carried out only by an experienced person skilled in the art with weave experience.
The mixing effects are to be generated owing to the low resolution of the human eye.

Embodiment Construction
[0037] Reference is made to FIGS. 1 to 4. FIG. 1 shows, in the form of a block diagram, the steps necessary for producing a Jacquard fabric with an illustration.
[0038]FIG. 2 shows a model with the illustration to be woven, which is converted into image dots by color breakdown and forms the basis for a weaving program (FIGS. 2 and 3). A version of a fabric according to the invention, which is described below, is then produced by means of a Jacquard weaving machine.
[0039]FIG. 5 shows a paper weave design for the fabric to be produced, according to which weft threads in the basic colors red R, green G, blue B, yellow Y, black S and white W are inserted in a defined sequence. The insertion of the weft threads and the movement of the warp threads (upstroke and downstroke) are regulated by means of this paper weave design. The weave is obtained according to the image dots generated during the color breakdown of the illustration. As FIG. 5 shows, a red and a green image dot are to be gen...

A patterned fabric having warp threads and weft threads that form an illustration. The weft threads are arranged to form a threaded group and, together with at least one warp thread, form a cell. The weft threads are tied off in the cell by the warp thread so that the cell has a defined color impression. The cell has weaves formed irregularly in a warp direction and a weft direction by at least two of the warp threads and two of the weft threads without periodic repetition.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This is a divisional of U.S. patent application Ser. No. 10 / 468,530, filed Aug. 19, 2003 in the name of Francisco Speich and entitled PATTERNED FABRIC AND A METHOD FOR THE PRODUCTION THEREOF, which is a 35 U.S.C. §371 National Stage of International Application No. PCT / CH02 / 00088, filed on Feb. 14, 2002. Priority is claimed on that application and on the following applications: Countries: Switzerland, Application No. 299 / 01, filed: Feb. 20, 2001 and Switzerland, Application No. 1027 / 01, filed: Jun. 6, 2001.TECHNICAL FIELD [0002] The invention relates to a patterned fabric, in particular a Jacquard fabric and to a method for producing it. PRIOR ART [0003] WO 00 / 60151 describes a patterned fabric and a method for producing it in the fabric technique with warp threads which form a shed and with weft threads. In this method, at least four weft threads of different basic colors, which form a thread group, are inserted in a defined constant s...
