Recovery from Tensile Strain in Knitted Cotton Fabric after Cross-Linking

Abstract

Extension under tensile load and recovery from extension was studied on a jersey knit cotton fabric after cross-linking treatments. The cross-linking reduces breaking strength and elongation-at-break, with only small changes in the load- elongation curve up to the break point. Set resulting from a high load is reduced by an amount approximating the reduction in extension; actual recovery is increased only slightly. Length increase from reheated loading can be reduced by cross-linking, but the extent of reduction is also influenced by noncross-linking additives.
