Abstract: Nonwoven needle-punched polypropylene fabrics have been prepared by varying the number of passes, keeping all the machine parameters constant except strokes/min. and the effect of number of passes on tensile and tear properties has been studied. With higher number of passes, there is very little effect on tensile strength and work of rupture but initial modulus increases considerably in cross direction. On the contrary, higher number of passes increases tensile strength, initial modulus and work of rupture but lower the elongation in machine direction. Tear strength, tear elongation and work of rupture decrease with higher number of passes.
