A comprehensive handle evaluation system for fabrics: I. Measurement and characterization of mass and bending properties

摘要

The main content dealt with in this paper is to present a new apparatus and a new method that can measure multiple mechanical properties through a single test in principle, which can be used for handle evaluation for textile materials. The comprehensive handle evaluation system for fabrics and yarns (CHES-FY) is a kind of apparatus that is capable of measuring mass, bending, friction and tensile behavior just through one pulling-out test, and is able to characterize the handle of fabrics, whose measurement principle and structure of the CHES-FY system in mass and bending steps are analyzed in the present paper. The shape of a hung fabric was captured by a digital camera, and its weight was calculated. Then, a three-point bending in principle was utilized to model and analyze the bending properties of the fabric, and the corresponding formula was obtained for calculating the bending rigidity of the fabric. The comparisons of mass and bending rigidity based on 17 fabrics have been conducted by using CHES-FY, electronic balance and KES-FB2, respectively. The measured results show that there are high correlations between the three measuring systems for fabrics. It indicates that the approach using CHES-FY is feasible and accurate in measuring and characterizing mass and bending rigidity.
