The KES-FB1-A Tensile and Shear Tester analyzes hand movements-referred to as “tensile” and “shear”-performed by artisans and professionals when judging a fabric’s texture. This device performs these movements mechanically, making it possible to obtain objective numerical data.

Obtainable data includes tensile/shear rigidity, tensile energy, elongation rates, and recoverability for such targets as cloth, paper, non-woven fabric, and film.
Tensile and shear characteristic data is useful for determining stiffness and anti-drape stiffness. These properties often influence form stability and the tendency for wrinkles.

• KES-FB1-AW Tensile and Shear Tester (for thick sample)


  • Improved data accuracy

    Sample slack is removed through motor chucking and clamping, eliminating errors caused by the user and thus improving the accuracy of data.

  • Display resolution: 0.01

    The KES-FB1-A makes it possible to quantify minute differences in tensile and shear properties.

  • Textile
  • Non-woven fabric
  • Paper
  • 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.
