Abstract
Jute fabric hessian cloth was grafted with 2hydroxy ethylacrylate HEA and aliphatic urethane diacrylate oligomer M1200 under UV radiation at different intensities 16 20 30 40 50 and 60 pass in order to improve the mechanical and electrical properties The concentrations of the monomer HEA and oligomer M1200 radiation dose and soaking time were optimized with respect to mechanical property such as tensile strength TS of the treated and untreated hessian cloth The 73 HEA 25 oligomer M1200 and 2 photoinitiator Darocur1116 in 1 minute soaking time showed the highest TS at 50th UV pass The electrical properties such as dielectric constant and loss tangent of both treated and untreated sample were measured at frequency 10 kHz with the variation of temperature It was observed that dielectric constant and loss tangent increased with increasing temperature up to the transition temperature and then decreased
