The KES-F8 allows measurement of ventilation resistance. Compared with commonly used measuring methods, the KES-F8 is capable of highly accurate measurements in just a short amount of time. In addition, measurements can also be obtained with minute amounts of ventilation (measurement conditions similar to ventilation conditions when clothes are worn).
Smaller values mean higher breathability and permeability
The Kawabata Evaluation System, centered on Sueo Kawabata, a professor at Kyoto University, and Masako Niwa, a professor at Nara Women’s University, is an objective evaluation method for measuring the texture of clothing fabrics based on the “The Standardization and Analysis of Hand Evaluation” provided by the Hand Evaluation and Standardization Committee of the Textile Machinery Society of Japan.
