What is the Kawabata measurement system?
The Kawabata Measurement System, also known as the Kawabata Evaluation System, is a comprehensive method developed by Dr. Satoshi Kawabata for evaluating the physical properties and handle (feel) of textiles. It was created to provide quantitative measurements and objective assessments of various fabric characteristics.
The system was designed to analyze and assess the tactile and mechanical properties of fabrics, including their smoothness, stiffness, softness, thickness, compressibility, and surface friction. These measurements are valuable for fabric manufacturers, designers, and researchers to understand and compare the performance and handle of different fabrics.
The Kawabata Measurement System consists of various instruments and testing methods, which are used to obtain data related to different fabric properties. Some of the key instruments and tests within the system include:
KES-FB System: This system measures the mechanical properties of fabrics, including tensile strength, bending stiffness, shear stiffness, compression, surface friction, and other parameters related to the fabric’s structural and mechanical behavior.
KES-F System: This system focuses on evaluating the fabric’s thermal properties, such as thermal conductivity and thermal resistance. It provides information on the fabric’s ability to insulate and regulate heat.
KES Spreading Test: This test measures the fabric’s ability to spread or drape over a surface. It quantifies parameters like surface smoothness, fullness, and flexural rigidity.
KES Shear Test: This test determines the shear properties of fabrics, evaluating their resistance to deformation under shear forces.
KES Compression Test: This test assesses the fabric’s compressibility and resilience by measuring the compression behavior and energy absorption properties.
By combining the data obtained from these tests, the Kawabata Measurement System generates a comprehensive evaluation of a fabric’s properties, allowing for comparisons between different fabrics and the prediction of their performance in various applications.
The Kawabata Measurement System has become widely adopted in the textile industry and research fields. It provides a systematic and scientific approach to understanding and characterizing the handle and physical properties of textiles, aiding in fabric development, quality control, and fabric selection for specific end uses.
