Tensile properties of jute yarns improved with organo-metallic complexes

A number of formulations was prepared with oligomer urethane acrylate (Eb-2 64) combined with a diluent monomer of different acrylated functionalities in the presence of a plasticizer, an antibubbling agent, ligands, and organ o-metallic complexes. The complexes were made with benzo-hydroxamato-pyridi ne (complex 1) and benzohydroxamato-ethylenediamine (complex 2) in the pres ence of TiO2. Thin polymer films were prepared under ultraviolet (UV) radia tion with these solutions and were characterized. A jute-plastic composite was prepared with these solutions under UV radiation. The tenacity of the t reated jute was increased by about 25% with reduced water absorption abilit y, but the presence of a minute amount (0.1%) of an organo-metallic complex in the formulation also enhanced jute tenacity up to 223%. The effect of t heir ligands on these properties was also investigated; both of the complex es substantially enhanced the properties of jute yarns rather than their li gands.
