A Study on Quantifying the Emotional Quality Applied to a Materials Analysis Method for Genuine Automotive Leather

摘要

This study is concerned with the technique of quantifying and digitizing four kinds of emotions felt by customers with products, utilising the material quality control analysis methods to control leather materials for vehicles. Through the measurement of protein quantity and microscopic observation, this study conducted an authentication of natural leather and the discrimination of the grade of leather; customers 'motions, sensory characteristics, such as touch sensibility and flexibility were defined through an analysis of the fatliquoring agent contained in leather. As for visual characteristics, the luxury felt when we look at the leather surface composed of a dense structure was analysed in relation to the pore density of the leather surface, the phenomenon of loose grain or creases was investigated by an analysis of the pores between the fibrous layers of leather and the density. The developed comprehensive analysis technique can enable the development of the optimum material that reflects the customer's needs and be widely utilized in improving leather materials through investigating the causes for the problem of quality.
