The KES-FB2-L Large Bending Tester accurately and quickly measures factors related to curvatures in small bending moments (bending hardness and recoverability). Adding to the small area available with conventional models, the KES-FB2-L enables measurements that were not previously possible, such as large bending moments and bending rigidity of thick sheet material and composites (products) made from multiple materials. The device also offers excellent data reproducibility in addition to easy measurement.
The KES-FB2-L has been put to use in a variety of industries, including the automotive industry.


  • 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.

  • Measured values are obtained using a power meter with sensitivity matching that of a fingertip, so results are consistent with sensory evaluations.

Example of Measurement Samples

  • 纤维 Textile
  • 无纺布(纸尿裤) Non-woven fabric (Disposable diapers)
  • 皮革、合成皮革(车座) Leather/Synthetic leather (Car seats)

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.
