Comparison of KEMOMI technique between master craftsman and unskilled worker

Abstract

The Nara FUDE, made of several kinds of fibers with different properties, can achieve quality. However, the insufficiency of the mix process of the fibers may lead to the unstable quality of the final product. Fiber bundle of about 400 pieces of brush were mixed by hand at one time, which was called ‘KEMOMI’. In this study, subjects with three different experiences were chosen (Master worker with 17 years of experience, Intermediate worker with 8 years of experience, Unskilled worker with 8 month of experience.). Refer to the method of the analysis of ‘KEMOMI’, three colours were in the rested fiber bundle, two kinds of filaments painted red and blue on the opposite of the taper side as well as the non-painted white colour. In order to analyse the progress degree of KEMOMI, binary coded processing was carried out on the picture taken every elapsed time during ‘KEMOMI’.
