dc.description.abstractThermal resistance and air permeability of needle-punched nonwoven fabric made from jute and polypropylene blends have been studied using the Box and Behnken factorial design to observe the effect of fabric weight, needling density and blend proportion on thickness, thermal resistance, specific thermal resistance, air permeability and sectional air permeability. Correlation matrix and cluster analysis have also been used to understand the relationship and grouping behaviour of the dependent and independent variables. It is observed that the thermal resistance and thickness increase but air permeability and sectional air permeability decrease significantly with the increase in fabric weight at all levels of jute contents. Significant (p < 0.05000) negative correlations r = – 0.67 and r = – 0.61 exist between needling density & thermal resistance and needling density & specific thermal resistance respectively.  The highest thermal resistance and specific thermal resistance have been obtained at 430 g/m2 fabric weight and 150 punches/cm2 needling density. All dependent variables are highly influenced by fabric weight (Euclidean distance ~ 560) which is a different cluster identity.en_US
