Embodiment 1

[0017] See attached figure 1 , this embodiment adopts the following steps to generate the color scheme of the color digital jacquard:

[0018] (1) Determine the parameters of the jacquard tissue unit

[0019] ① Determine the size of the jacquard unit. If 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 requirements of the colorful jacquard product. Considering the above factors, the number of weft yarns in the design jacquard weave unit is m, and the number of warp yarns is n, where 4≤m≤6, 2≤n≤4.

[0020] ② Yarn color selection. Select m+n colors of yarns according to the jacquard weave unit designed in ①, and set their color values ​​as C 1 , C 2 ,...C m+n , and its RGB color component values ​​are (R 1 , G 1 , B 1 ), (R 2 , G 2 , B 2 )……(R m+n , G m+n , B m+n ).

[0021] ③Determine the seq...

Abstract

The invention discloses a method for controlling digital jacquard-woven colored patterns. The method comprises the following steps of: determining the parameters of a jacquard weave unit and obtaining the visual colour value corresponding to each intersecting point in the jacquard weave unit by a colour space hybrid colour processing method; and removing the same visual colour data, keeping the visual colour data of an interweaving way, after filtering the data by contrasting a standard 256 colour list by a colour difference computing method, comparing the colour of each pixel point of the colored patterns input into a computer with the visual colours of the jacquard weave unit to obtain the colours with the maximum colour similarity, forming a program, and controlling the digital jacquard to weave colored patterns. All the similar colours in the standard 256 colour can be prepared from yarns with fixed colours without manually selecting the colours of yarns; and the back of a provided jacquard product is relatively flat, so the quality and added value of the product are improved.

Description

technical field [0001] The invention relates to a method for color matching of warp and weft interwoven fabrics, in particular to a method for controlling a digital jacquard machine to weave color patterns. Background technique [0002] In traditional color digital jacquard, before jacquard a color picture, professional technicians need to analyze the color information of the picture, and then choose which color yarns to use according to the analysis results and personal experience. When the tone of the picture is relatively single, it is relatively easy for technicians to analyze the color information, but it is very difficult to analyze the picture with rich colors. In addition, there are great personal subjective factors in the selection process of yarn color. Even if it is the same picture, the color of yarn chosen by different technicians is often inconsistent. [0003] Air-jet color jacquard loom is a loom that uses jet airflow to pull the weft yarn through the shed. ...
