We are interested in Polyester staple nonwoven (bonded) fabric Width, cm - 100 Surface density (gr/m2) - 100/120 Thickness (mm) - 0,6-0,4/0,6-0,8 Tensile strength, N/cm (lengthwise) - 60/50 Tensile strength, N/cm (across) - 70/60 The thing we care about especially is the tensile strength of the material.
