Mechanical and Electrical Properties of Photocured Jute Fabric with 2-Hydroxy Ethylacrylate

Jute fabric (hessian cloth) was grafted with 2-hydroxy ethylacrylate (HEA) and aliphatic urethane diacrylate oligomer (M-1200) 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 (H EA), 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 (M-1200) and 2% photoinitiator (Darocur-1116) 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.
