Kawabata Evaluation System KES-F Handle Measurement
topic
The Kawabata Evaluation System measures sixteen mechanical and surface properties of fabrics across five specialised instruments — tensile and shear tester, pure bending tester, compression tester, surface friction and roughness tester, and thermal property measurement — from which primary hand values describing stiffness, smoothness, fullness, and resilience are calculated using regression equations derived from expert fabric hand panel assessments of suiting fabrics. The system provides a comprehensive mechanical fingerprint of fabric hand enabling quantitative comparison of fabrics, prediction of garment making performance, and quality control specification of handle attributes. Originally developed for woven suiting fabrics, the system has been extended to knitwear, technical fabrics, and nonwovens with modified interpretation equations appropriate for each fabric category.
Role
The Kawabata Evaluation System is the most comprehensive objective fabric handle measurement system available — translating the complex multidimensional sensory experience of fabric hand into a set of quantitative mechanical parameters that fabric developers and garment manufacturers use to specify, compare, and quality-control the tactile properties of fabrics in markets where hand feel is a primary product differentiator, particularly in premium suiting, luxury knitwear, and performance base layer fabrics.
