Abstract

Jute yarns were grafted with a single impregnating monomer 1,6-hexanediol diacrylate (HDDA) in order to improve the physicomechanical properties. Jute yarns soaked for different soaking times (3, 5, 10, and 30 minutes) in HDDA+MeOH solutions at different proportions (1–10% HDDA in MeOH [v/v] along with photoinitiator Darocur-1664 [3%]) were cured under UV lamp at different UV radiation intensities (two, four, six, and eight passes). Concentration of monomer, soaking time, and intensity of UV radiation were optimized with extent of mechanical properties such as tensile strength, elongation at break, and modulus. Enhanced tensile strength (67%), modulus (108%), and polymer loading (11%) were achieved with 5% HDDA concentration, 5-minute soaking time, fourth pass of UV radiation. To further improve the mechanical properties, the jute yarns were pretreated with UV radiation (5, 10, 15, 30, and 50 passes) and treated with optimized monomer concentration (5%). UV-pretreated samples showed the enhanced properties. The tensile strength and modulus increase up to 84% and 132%, respectively, than that of virgin jute yarn. An experiment involving water absorption capacity shows that water uptake by treated samples was much lower than that of the untreated samples. During the weathering test, treated yarns exhibited less loss of mechanical properties than untreated yarns.
