The aim of this study is to analyze the bursting strength of polyester/viscose blended needle-punched nonwovens. For this purpose, five different blend ratios of polyester/viscose webs were produced, cross-lapped and needled in four different mass per unit areas and three different needling/punching densities. The bursting strength of 60 nonwovens was determined by performing the standard test method; the data obtained from tests were statistically analyzed in Design Expert software. In addition, a mixture process crossed-regression model with two mixture components (polyester and viscose blend ratios) and two process variables (fabric mass per unit area and needling density) was developed to analyze the bursting strength of polyester/viscose blended needled nonwovens. In conclusion, the regression model indicated that the bursting strength of the needle-punched nonwovens initially decreases and then increases with the increase of polyester fiber in the mixture and with the increase in mass per unit area. On the other hand, when the mass per unit area is kept constant, an increase in needling density causes decreases in bursting strength.
