Tensile and Shear Tester

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.

● 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.

Measurement Sample Example

  • General fabric
  • Fabric
  • Medicinal fabric
  • Car seats
  • Interior fabric
  • Non-woven fabric

Obtainable Data

Item Characteristic value Description Reading the data
LT Tensile rigidity Values closer to 1 mean firmer tensility
WT Tension energy Higher values mean greater stretchability
RT Recoverability Values closer to 100 mean better recoverability
G Shear rigidity Higher values mean harder shearing
2HG Elasticity for minute shear Higher values mean poor recoverability from initial shear deformation
2HG5 Elasticity for large shear Higher values mean poor recoverability
  • Auto Data Processing Unit (optional)

    Connecting this device to the instrument and to a PC allows the waveforms and numerical values of measurement data to be output.
    Obtained data can be saved as BIN data or CSV data.

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.
