Abstract: The woven fabric of complex structure is always designed by a combination way,which is hard to approach for its complicated design process and design variation.Along with the application of layered combination design method of digital woven fabric,the structure design of woven fabric can be performed in a mode of weave-database design replacing the traditional single weave design.Based on design of gamut weaves and weave-database,an investigation is carried out to analyze critically the combination principle among different weave-database,on which a scientific design method is presented.It is envisaged that the results of this study can be directly applied to creation of digital woven fabric,especially to innovative digital jacquard fabric designed in a layered combination way.
