MODIFICATION OF JUTE YARN BY GRAFT-COPOLYMERIZATION WITH ULTRAVIOLET RADIATION

摘要

A number of formulations was developed with oligomer mixed with functional monomers in the presence of fillers and plasticizer. Then polymers were prepared under UV radiation with these formulated solutions. The films were characterized to determine film hardness, gel and tensile properties. Jute yarns were treated with these formulated solutions and cured under the same UV source. More than 80% grafting occurred with the yarn; mechanical strength of the treated yarn increased to 55% and its elongation enhanced by 3 fold. Simulating weathering caused tensile strength loss between 40 and 70% and elongation by 40-70% depending on the formulations. The jute yarn plastic composite was found to be quite durable in normal conditions but it can be made degradable in certain environmental conditions to different degrees depending on the nature of the formulations.
