The Kawabata evaluation system (KES) is used to measure the mechanical properties of
fabric Textile is an umbrella term that includes various fiber-based materials, including fibers, yarns, filaments, threads, different fabric types, etc. At first, the word "textiles" only referred to woven fabrics. However, weaving is not th ...
s. The system was developed by a team led by Professor Kawabata in the department of polymer chemistry, Kyoto University Japan. KES is composed of four different machines on which a total of six tests can be performed: * Tensile & shear tester –
tensile In physics, tension is described as the pulling force transmitted axially by the means of a string, a rope, chain, or similar object, or by each end of a rod, truss member, or similar three-dimensional object; tension might also be described as ...
,
shear Shear may refer to: Textile production *Animal shearing, the collection of wool from various species **Sheep shearing *The removal of nap during wool cloth production Science and technology Engineering *Shear strength (soil), the shear strength ...
* Pure bending tester – pure bending * Compression tester – compression * Surface tester – surface friction and roughness The evaluation can include measurement of the transient heat transfer properties associated with the sensation of coolness generated when fabrics contact the skin during wear. The KES not only predicts human response but understands the perception of softness.
