Abstract

The role of strain level in the assessment of wrinkling performance of 100% cotton fabric treated with various in-wear wrinkle-resistant (IWWR) additives was investigated. Two additives, a cross-linking agent and a fabric lubricant were both separately and in combination applied to cotton fabric samples. In this investigation multiple laboratory tests were used, including fabric bending hysteresis and stress relaxation under medium to high curvatures, fabric shear, controlled laboratory fabric wrinkling (wrinkle tester) as well as crease recovery angle measurements. The results were analyzed, with reference to the viscoelastic and frictional model of fabric wrinkling, in order to evaluate the IWWR performance of the treated and untreated fabric samples objectively and quantitatively. The correlation between these results and the subjective evaluation of wrinkle recovery performance of shirts in an in-wear panel test was evaluated.
