Tensile characteristics of sisal and polypropylene fibre non-woven materials for geo-textile applications

The objective of this study is to analyse the cross direction tensile properties of composite non-woven fabrics. Three different blend proportion, that is, 20% sisal/80% polypropylene, 80% sisal/20% polypropylene and 50% sisal/50% polypropylene were used to study the tensile properties of the composite non-woven fabrics. Box–Behnken design has been used with three parameters namely, punch density, depth of needle penetration and mass per unit area. The samples produced were subjected to calendaring at 145℃ temperature and 6.12 kg/cm ² pressure. The tensile strength of tested fabrics has been analysed in detail and it has been found that 20% sisal/80% polypropylene composite non-woven fabric is performing better than other blends.
