Abstract: Different color of yarn and fabric structure could get Weft-all-coloring jacquard fabric through suitable matching, which could obtain various kinds of floriated pattern from fabric surface and rich color. Because of the colorful yarn and fabric structures, color designing still remains a problem to be solved in production. In addition, there haven’t ideal colorful model to predict jacquard fabric structure. In view of the above problems , this paper use five primary samples, white, blank, red, yellow and green yarn to prepare many weft-all-coloring jacquard fabric of single-warp and double-weft. Though a large number of exprimental color about a datacolor 600 plus spectrophotometric, we can calculate the theory of Kubelka-Munk absorption coefficients (K) and scattering coefficients (S) of all yarns and color proportion of weft jacquard fabric with all-coloring. The results show that the theory of Kubelka-Munk can good explain the relationship between color of weft jacquard fabric with all-coloring and color proportion.
