First, marking the position forming the scratch mottle texture spot in the selected simulation image picture, and counting. Taking one section of picture of deer Wang Bensheng as an example, the specification and the size of the picture are 1545×880 in terms of pixels A×B, scratch-shaped textures are marked by using Photoshop software, the selection of spots is representative, the spots cannot be overlooked, the spots are expressed in a form suitable for being expressed by section color yarns, and the spots distributed along the weft yarn direction are selected as much as possible. As shown in figure 1, the five-pointed star mark is used for marking the position where the white scratch-shaped texture spot n is 106, and the distribution randomness is more remarkable.
(2) The design calculation method of the segment color yarn is to determine the color length (or called pitch length) and the color distance (or called pitch length) of the segment color yarn. The color length of the segment color yarn can be calculated by directly measuring the number of pixels of the length of the white scratch in the picture and then calculating the color length on the cloth cover. According to the design requirement of the design style of the fabric product on the pattern size, the length dimension L of the finished fabric surface representing the picture is designed j The dimension is about 35cm (weft direction in the picture) calculated from the width of the conventional flower cloth cover of 2520 needles jacquard flower type, and the width of the picture on the cloth cover + the width of the decorative lace on the cloth cover is a complete flower cloth cover width. Warp and weft yarn density P of fabric j And P w 681/866 pieces/10 cm respectively, and the warp shrinkage of the fabric is preset to be a according to experience jz 10% weft shrinkage a wz The warp dyeing shrinkage a of the fabric is preset to be 8 percent jr 0% weft dyeing shrinkage a wr 8%.
