This paper introduced an innovative method of description of the structure of multi-layered woven fabrics (MLWF). The method enables a complicated design procedure for the MLWF to be reduced to the much simpler design process of a single-layer woven fabric using conventional CAD systems. The method can be applied to all types of common MLWF including orthogonal and angle-interlock woven structures. This method will be widely used in the textile industry for the design of multi-layered woven fabrics and by the software companies which provide CAD/CAM systems for the industry.
