Embodiment 1

[0018] See attached figure 1 , which is a schematic flow chart of the color jacquard color scheme with a large number of stitches provided in this embodiment; the following steps are used to generate a color jacquard scheme with a large number of stitches:

[0019] (1) Determine the parameters of the jacquard tissue unit.

[0020] ① Determine the parameters of the jacquard weave unit. According to actual needs, considering that the size of the jacquard unit is too large, it will reduce the fineness of the jacquard product and affect the visual effect; if it is too small, the number of color types produced will be too small, which cannot meet the colorful requirements of the jacquard product. Considering the above factors, the number of weft yarns in the design jacquard base unit is 3≤m≤6, and the number of warp yarns is 2≤n≤4.

[0021] ② Yarn color selection and arrangement. Select m+n colors of yarns according to the jacquard weave unit designed in ①, and the order of weft...

Abstract

The invention discloses a method suitable for weaving a colored jacquard fabric with a large texture thread number. The method comprises the steps of firstly determining parameters of jacquard texture units, and storing the parameters in a database; then determining the parameters of jacquard color lumps and the size and extension sequence of pattern image blocks, reading colored design patterns to be woven into a computer for division, and carrying out index numbering; and scanning each pixel point for calculation of color difference, arranging the jacquard color lumps based on a weaving scheme with maximal color similarity in a color library to form a weaving program, and splicing all jacquard subblocks after controlling a colored digital jacquard machine to weave respectively. The method can complete the jacquard design and weaving of color images by only utilizing 4-8 colored yarns and achieve the jacquard task with the large texture thread number on the premise of not bringing up new demands on a conventional jacquard machine process; and simultaneously the color level breaks through 256 colors in color selection so as to be more colorful and improve the quality and additional value of products.

Description

technical field [0001] The invention relates to a method for realizing color separation processing suitable for weave for large image files, in particular to a method for realizing a color jacquard scheme with a large number of stitches. Background technique [0002] The industrial application of the electronic jacquard machine has only been for more than ten years. Due to the control of a single warp, it can weave very complex patterns and structures by weaving. The number of stitches of the early electronic jacquard machine faucet is mostly less than 2688, which is mainly used for the application of small pattern fabrics such as trademarks, ties, and ribbons. In recent years, people's demand for colored jacquard fabrics with large number of stitches is increasing day by day. The larger the pattern, the greater the required number of jacquard stitches. With the advent of the leading electronic jacquard machine with more than 5120 needles, the application field of the elect...
