The KES-FB2-S Pure Bending Tester is capable of measuring hardness and recoverability when bending not only paper and non-woven fabric but also hair and film. Measured values are obtained using a power meter with sensitivity matching that of a fingertip, so results are correlated with sensory evaluations. The device provides accurate measurement even for samples with different processing methods, such as surface treatments and flexible processing. The KES-FB2-S is a multi-purpose pure bending tester that can be used without having to worry about the type of objects being measured.


  • Measure hardness and recoverability when bending paper, non-woven fabric, and cloth through pure bending tests.

  • Measure treatment differences (such as flexible processing surface treatment).

  • Hardness and recovery capabilities when bending can be read instantly, allowing for simple data analysis.

  • The tester obtains values that detect micro areas in suppleness, firmness, and stiffness.

Example of Measurement Samples

  • Textile
  • Non-woven fabric
  • Paper
  • Hair
  • 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.
