Abstract :Spunbond method is widely used in the production of nonwoven fabrics. Melt flow index insert ignore into journalissuearticles values(MFI); is one of the most important polymer processing parameters. In this paper, tensile strength and elongation values of spunbond fabrics with four different weights produced from polypropylene polymers with two different MFI values were measured. Tensile strength tests were analyzed by two-way multiple variance analysis insert ignore into journalissuearticles values(Two-Way Manova); in the SPSS statistical package program, and the effects of MFI and weight values on the strength properties of spunbond textile surfaces were examined. As a result of the statistical analysis, it was observed that statistically significant differences insert ignore into journalissuearticles values(p < 0.05); occurred in both tensile strength and elongation values with the change of weight value. In addition, significant differences insert ignore into journalissuearticles values(p < 0.05); occurred in tensile strengths with the change of MFI value, but the differences in elongation values were not statistically significant insert ignore into journalissuearticles values(p > 0.05);.
