Description

Fabric tissue design method for improving fineness of color image scene picture
Technical Field
The invention relates to the technical field of textile design, in particular to a fabric tissue design method for improving the fineness of a color image.
Background
The color image fabric is a design method which applies a digital simulation technology to the textile field through a digital jacquard weaving technology, designs and adjusts color pictures into continuous and arrangeable produced pictures, and adopts a jacquard CAD technology to design and produce the color image fabric. The design is carried out according to the characteristics of the picture which shows the definition degree of the picture through the resolution ratio, the pixel points are more when the resolution ratio is higher, and the image in the picture is restored by adopting the interweaving times of warp and weft yarns in the principle of color expression in the color image scene fabric. In the design of such products, in order to improve the high reduction effect of the landscape fabric, the length of the floating long threads of the tissues is generally increased to improve the color expressive force, namely, the tissues with larger cycle numbers are selected, the floating long threads of the tissues with larger cycle numbers are longer, the increase of the floating long threads directly affects the fineness of the fabric picture, and meanwhile, the wear resistance of the fabric is affected, and the problem of hooking easily occurs, so that the use experience of the finished product is affected.
The prior art aims at improving the color development problem of the fabric by realizing the color development of the non-shading color yarn through the tissue structure, and does not disclose a design method for improving the picture fineness. In patent CN 1772989B, it is proposed that, in order to obtain a good shadow effect, the reinforcing direction of the basic structure is first right and then left, the reinforcing direction of the matching structure is first left and then right, the midway direction of the reinforcing direction is turned to have a certain degree of alleviation effect on the problem in an objective manner, and the arrangement of the basic structure opposite to the reinforcing direction of the matching structure can further improve the slippage between the adjacent yarns, because even if the full-color development technical point is set, the situation of partial slippage coverage can occur between the adjacent yarns within the length range of the floating long line, but the staggered manner of the adjacent weft tissue points can affect the color development of the parallel port, i.e. the picture fineness problem is affected. In the patent CN 105970435A, a mode of dividing a picture into five-color images and weaving the five-color images is adopted, and in the design of a pattern, a mode of transition from weft satin to plain weave to warp satin is adopted, but the mode is only suitable for the weaving of low-density fabrics, meanwhile, the mode has the problems of satin and plain weave application in the design of a weave, the combination mode has unstable weave structure in actual production, only the low-density fabrics can be produced, and meanwhile, the too small warp and weft densities have certain defects in the aspects of color and picture fineness of color landscapes. The paper 'influence on fabric color development by setting the starting point position of the three-weft combined full-color development structure' analyzes the starting point position of the three-weft combined full-color development structure, namely, the analysis and verification of gradual color development effect and color saturation are carried out on the color development weft of the fabric structure by designing the starting point position of three groups of basic structures under an RGB format, and meanwhile, the reinforcing points of the paper are full-color development tissue banks formed in the same rightward increasing mode, so that the method has a certain effect on fabric picture saturation and color improvement, but the problem exists that no matter how the starting point position of the tissue points changes, whether the starting point position of the tissue points changes is in the right increasing mode or the inclined patterns of cloth covers are too obvious, the inclined patterns of the cloth covers are presented in the inclined patterns of the riding, and meanwhile, the floating lines of the basic structures with larger cycle numbers are too long, and the phenomena of thread hooking and wear resistance are easy to occur in the use process.
