Compression Tester

The KES-G5 Compression Tester analyzes hand movements—particularly, movements by finger—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-FB3-A Compression Tester.

Obtainable data includes compression rigidity, compression energy, and recoverability.
The machine can be applied to a wide variety of fields and purposes, including determining the softness of disposable diapers and the hardness of mousse.

● Various attachment shapes

Choose from variously shaped compression sensors tailored to the sample being measured, for silicon material, how easy buttons can be pushed, car seats. etc.

Measurement Example

  • Car seat comfort

  • Hygiene product softness

  • Hardness, elasticity, and thickness of non-woven fabrics

  • Sponge hardness: Elasticity

  • Cosmetic puff softness

  • Hardness of foam

  • Towel softness

  • Firmness of leather

Compression Sensor Lineup

  • Size: 2 cm2

    Standard accessory

  • Size: 20 cm2

    Softness evaluation for towels, etc.

  • φ10 mm (spherical)

    Evaluation of car seats, instrument panels, center consoles, etc.

  • Silicon material

Obtainable Data

Item Characteristic value Description Reading the data
LC Linearity of Compression Values closer to 1 mean firmer compression
WC Work of Compression Higher values mean higher compression susceptibility
RC Recoverability of Compression Values closer to 100 mean better recoverability
  • USB 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.
