“…Grey simulative fabric refers to fabric whose visual effects such as pattern and color are capable of imitating that of given grey images [6]. With the development of computer skills, digital production technique [4,7] and application of layered-combination design mode [8,9], using digital image design directly into fabric become a reality. Design grey fabric by tailor-made gamut weaves based on a colorless design mode and single-layer structure has improved efficiency greatly [10,11], but single-layer structure can't avoid the cover of apposition yarns, and this problem is getting worse in large pattern or density, plus nontransparent yarns, shading effect of fabric is not good.…”
