EFFECT OF MECHANICAL CRIMP OF JUTE FIBRE ON THE THERMAL PROPERTIES OF WOVEN FABRICS

Abstract

The aim of this paper is to find the effect of mechanical crimp of jute fibre on the thermal properties of woven jute fabrics. In this study, crimp box and gear crimping method were used to impart mechanical crimp into jute sliver. Crimps were divulged to enhance the cohesion between fibres that make it suitable for spinning. Jute yarns were produced by inserting a different number of crimps and woven fabrics were produced by using these yarns. Fabric thickness, porosity, air permeability and thermal conductivity tests were done according to standard method and found that fabric porosity, air permeability and thermal conductivity of the fabric decreased and fabric thickness increased with the increased number of crimps and fabrics from gear crimping method showed better effect than that of crimp box method. The study on jute woven fabric will provide quantitative experimental data for potential applications with advantages of lightweight, cost-effective, easy to manufacture, biodegradable and excellent mechanical properties.
