Creative shading effect in digital jacquard textiles

PURPOSE/OBJECTIVES OF STUDY This study aims at optimising the structural design method of creative shading effect in digital jacquard textiles. Based on appropriate weaving structure design, diverse shading effects are developed for woven fabrics. Reference was made to the full-colour compound structures [1] [2], of which the optimal conditions in jacquard weaving structures was proposed for representing shading colour effects on the fabric surface against a given gradated image. The principles of structural designs are adopted while the size of single weaves is expended and created with different increases of interweaving points. It was to testify the appropriateness toward an improvement of colour appearance and stability through modification of weaving structures by an extra weft figuring method with one end of white ground [3]. Since primary colours are defined as the 'first' or 'principle' colours which cannot be achieved by mixing any other colours [4], primary coloured yarns are thus considered as the first selections for the fillings to reproduce a wide scope of weave colours. The detailed objectives of this study are 1) to identify optimised structure formats and size scopes for natural colour representation via deployment of an electronic weave machine and jacquard CAD system and 2) to testify the possibility of enlarging weave colour ranges through mixing primary colour groups of filling yarns and 3) to expand and originate new design concepts of jacquards.
