FB4 - A Surface Performance Tester

Introduction This tester analyzes and mechanizes the hand movements of "stroking" by craftsmen and professionals when evaluating the style and hand - feel of fabrics, and converts the results into objective numerical data. It can obtain data on the friction coefficient, variation of the friction coefficient, and surface roughness of all fibers, fabrics, papers/non - woven fabrics, film - like samples, etc. The surface friction and roughness characteristic data will affect the "fluffiness", "smoothness" and "stiffness" of the style and hand - feel. Features - Equipped with sensors that simulate the sense of fingertips. - By simulating the load and surface treatment of the sensors based on the design of fingertips, the sensations close to those of human fingertips can be quantified.
