Abstract:

For the purpose of enriching the gradient mixed color on jacquard fabric, an innovative design method is carried out with respect to the features of jacquard fabric in which both of warp and weft play roles in expressing the final fabric color. In this method, color gradient effect on jacquard fabric is expressed on double-layer structure arranged with double warp yarn and double weft yarn through the interaction of weft and warp. This paper analyses the features of double-layer structure of jacquard fabric and the technological demand from the color gradient expression on jacquard fabric, and combines these two points under the premise of meeting the requirement of the technology by which jacquard fabric can be mass producted, in doing so, design principle and method of color gradient expression on double-warp double-weft jacquard fabric is proposed. In addition, it focuses on the design research and practice of the color card of single weft color gradient expression on fabric, the model of weave structure and an database of fabric weaves for the color card are formed, along with, the result of the practice has proved that this method is of application value, and structure of jacquard fabric designed by it can be used to develop new jacquard fabric product with color gradient effect.
