In this study, bamboo and polypropylene fibers have been selected to produce non-woven fabrics using needle punching machines. The non-woven fabrics were produced with bamboo and polypropylene blends of 80%/20%, 20%/80% and 50%/50%, respectively. The cross-directional tensile properties of produced non-woven fabrics were analyzed using Box–Behnken experimental design for three factors and three levels by varying aerial density, punch density and depth of needling penetration. It was observed that the 20% bamboo/80% polypropylene non-woven fabrics have higher tensile strength and elongation than the other two blend proportions. The tensile strength increases with increase in aerial density, punch density and depth of needle penetration.

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/cm2 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.
