doi:10.34104/ajeit.020.01060112

Abstract

The use of jute fabrics is showing an increasing trend in textile, building and automobile sectors. Electrical properties such as conductivity, resistance, di-electric constant, insulation, etc. are the essential factor for consideration for using jute fabrics in these sectors. For this reason, a study was carried out to find out the changes in electrical properties of woven and nonwoven jute fabrics at different input voltage. The electrical resistance of jute fabrics was measured by a digital impedance meter. Effects of input voltage, gauge length, and type of fabrics on electrical resistance were studied and analyzed. Experimental results indicated that the electrical resistance of woven and needle punched nonwoven jute fabrics decreased with the increase of input voltage and increased with the increase in gauge length. The highest value of electrical resistance in woven jute fabrics was 394 Mohm/cm at 2 cm gauge length and 60 V of the input voltage. In nonwoven jute fabrics, the maximum electrical resistance was 257 M ohm/cm which was obtained at 2 cm gauge length and 60 V of electrical resistance. Woven jute fabric showed a higher value of resistance than nonwoven jute fabric for different voltages. It was also observed that the electrical resistance varied with the type of fabrics used in this study.

Highlights

Jute is a common natural fibre which is produced on a wide scale in the Indian sub-continent, especially Bangladesh and has a nominal effect on the environment because of its biodegradable properties (Vilaseca et al, 2007)
At first woven jute fabric sample of 1.0 cm gauge length was placed on respective terminal
The highest value of electrical resistance was found for 2 cm of gauge length for both woven and non-woven jute fabrics

Summary

Introduction

Jute is a common natural fibre which is produced on a wide scale in the Indian sub-continent, especially Bangladesh and has a nominal effect on the environment because of its biodegradable properties (Vilaseca et al, 2007). Jute fibre has many advantages which are high mechanical and electrical properties, low cost, low weight, good thermal properties, enhanced energy recovery, biodegradability and so on (Bullions et al, 2004; Mohanty et al, 2000). Jute is the cheapest lingo- cellulosic long vegetable- based fiber and is abundantly available in Bangladesh (Akter et al, 2020). It is traditionally used for making hessian clothes, ropes, gunny and shopping bags, floor mats, etc (Rahman et al, 2008)
