Study on Some Functional Properties of Mesta Needle Punched Nonwoven Fabrics Using Central Composite Rotatable Design

The combined effect of two structure forming process parameters i.e. punch density and needle penetration on properties of Mesta needle punched nonwoven fabric has been studied using central composite rotatable design. As properties are structure dependent, the relationship between compressional behavior and other functional properties was studied. It was observed that compressional (α) and recovery (β) parameters are well correlated with tensile, air permeability and thermal insulation value of Mesta needle punched fabric. The regression equations were also suggested. Therefore, the α and β may be used for indirect approximation of these properties with reasonable accuracy.
