Color rendering in single-layer jacquard fabrics using sateen shaded weave databases based on three transition directions.

Shaded weaves are used in digital jacquard fabrics for expressing rich colors, especially in the design of figured jacquard fabrics. The original image process and shaded weave database (SWD) process are two independent design processes for the production of figured jacquard fabrics. SWD processes are relatively fixed, but original images vary frequently, and color value inconsistencies between the original image and its jacquard fabric are often neglected by researchers. This paper presents the design principles of a SWD based on a sateen basic weave and analyzes the color rendering of seven groups of fabric specimens produced using SWD processes with three transition directions and different step numbers. The color rendering characteristics of the SWD process were mainly determined by the transition direction of the interlacing points, but were also slightly affected by the weave’s step number when horizontal transitions were used. Three photographic images with different tones were selected to design three groups of single-layer figured jacquard fabrics. The results proved that the tone of a woven fabric is determined by the SWD process used, not the original image. A method was proposed to predict the final tone of a woven fabric by adjusting the lightness value of the original image according to the values of the fabric specimens of the SWD process that are used. This study outlines how the digital processing of a figured jacquard fabric design may be achieved using a SWD process based on one of the three design directions. [ABSTRACT FROM AUTHOR]
