Currently, objective measurements of textile fabrics refer to mechanical and physical properties measured by testing devices such as KES (Kawabata's evaluation system) and FAST (fabric assurance by simple testing). Textile scientists and engineers can easily obtain the values of these properties, but their use for developing models of fabric behavior is rare, although this is the simplest and most correct way to do it. Here, we develop an analytical model of the tensile force dependent on strain for a fabric sample, integrating the Kawabata parameters obtained by means of this test. The empirical stress-strain curves of some fabrics are presented and compared with curves obtained analytically.
This study examines the dependence of ramie and linen tensile properties on the molecular weight of cellulose as a function of moisture absorption. The influence of the crystalline region and molecular weight on tensile properties is investigated using mercerized and acid hydrolyzed cotton fibers. No influence of the crystalline region on ramie and linen tensile properties is detected, and the effects of moisture regain on the tensile strength and elongation of ramie and linen fibers decrease with decreasing molecular weight. The slope in the plot of tensile properties versus moisture regain becomes negative when the molecular weights of ramie and linen are below about 1.22 X 105 and 0.99 X 105, respectively. Changes in tensile strength and elongation with moisture absorption depend mainly on the number of molecular chain ends in the amorphous region.
