Electrical resistance of jute fabrics

Abstract

Electrical resistance of jute canvas, hessian and cross-laid needle-punched nonwoven fabrics has been measured in a laboratory made set-up. Effect of gauge length, voltage, moisture, fibre orientation, temperature, area density has been studied and analysed. It is observed that electrical resistance increases with the increase in gauge length and decreases with the increase in input voltage, moisture, temperature and area density. Jute hessian, canvas and nonwoven fabrics show the resistance value in descending order. Length-wise electrical resistance is higher than width-wise resistance of jute needle-punched nonwoven fabric, whereas in case of canvas and hessian the effect is reversed.
