What Is Texture Measurement?
Limits of Technology in Conveying Texture
“Texture” has long been referred to as what people feel when they touch an object, and has served as one of the criteria for determining quality. However, because hand sensitivity plays such a big role, only subjective evaluations are possible. Although professionals with many years of experience might be able to distinguish the subtle differences in materials, the average person may not be able to determine which product is better.
Converting Subjective Sensations to Objective Data
When distinguishing texture, people perform such actions as stroking, pulling, bending, and pushing on objects with a finger. Using precision measuring equipment to reproduce such human behaviors and sensitivity used when analyzing texture allows conventionally subjective and ambiguous judgments of an object’s physical properties to be replaced with objective data, which can be shared with anyone. This is the goal of texture measurement technology.
Texture measurement and KES (KAWABATA EVALUATION SYSTEM)
According to the basic designs and research of Dr. Sueo Kawabata of the Faculty of Engineering, Kyoto University, and based on the research and development of Dr. Masako Niwa of Nara Women's University, the KES System of Texture Measurement was introduced in 1970 as a system capable of replacing subjective judgment with objective data. “KES” is a standard abbreviation representing “KAWABATA EVALUATION SYSTEM.”
Today, texture measurement in the fields of fabrics, cosmetics, food products, paper, and automobiles is rapidly growing. And all over the world, the KES is being used to evaluate texture.
