Study on cross-directional tensile properties of bamboo-/polypropylene-blended needle-punched non-woven fabrics

Abstract

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.
