The KES-SESRU Roughness/Friction Tester analyzes hand movements-particularly, strokes-performed by artisans and professionals when judging a fabric’s texture. The device performs this movement mechanically, making it possible to obtain objective numerical data while offering more enhanced versatility over the KES-FB4-A Surface Tester.

In addition to average frictional coefficient and fluctuation of average frictional coefficient, surface roughness data is obtained. The device is also suitable for light texture conditions and hair measurement.


  • Sensor that imitates fingertips

    The sensor unit’s design features a load and surface treatment that mimics a fingertip, allowing for quantification similar to that of the human fingertip.

Example of Measurement Samples

  • Textile

  • Paper (Tissue)
  • Yarn
  • Coating
  • Wood
  • Liquid (Cream, Liquid foundation)
  • Powder
  • Hair
  • Leather/Synthetic leather (Car seats)
  • Film

KES (Kawabata Evaluation System)
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.


We offer free sampling services, "for a deeper understanding of our products", "for confirming the measured data that can be obtained", and "to prepare the data necessary for submission of internal approval documents". Please feel free to contact us.
