The work aims to provide new ideas and methods for the protection and inheritance of Liangping blue printed fabric, and add impetus to the creative transformation and innovative development of intangible cultural heritage.Literature review, field survey, DFA analysis, computer-aided design and other methods were used to study the traditional patterns of Liangping blue printed fabric. Firstly, based on the theory of cultural genes, the traditional patterns of Liangping blue printed fabric were identified and extracted. Then, shape grammar was used to deduce the extracted morphological genes, forming new pattern graphics. Finally, the new pattern graphics were applied to cultural and creative product design.The basic idea for the protection and inheritance of Liangping blue printed fabric patterns is to combine tradition and innovation. The cultural genes of Liangping blue printed fabric patterns are composed of morphological genes, structural genes, color genes, and connotation genes. Based on the morphological genes of the patterns, and with the structural genes, color genes, and connotation genes as constraints, a variety of pattern graphics can be deduced through shape grammar, and traditional and modern innovative cultural and creative products can be designed.
