The study is concerned with the continuation of further investigations of physical properties (reference of part 1) of needle punched non-woven textiles produced from virgin polypropylene and raw jute 40:60, 60:40 and 80:20 blended fibres using a Factorial Design Technique. The Box and Behnken Factorial Design has been adopted. Effect of non-woven fabric weight and needling density on tenacity (transverse direction), elongation at break (transverse direction), initial modulus (machine and transverse directions) of P.P.: Jute∷40:60 blended non-woven textile have been examined in this part 2. Effect of non-woven fabric weight and polypropylene: jute blend proportions on initial modulus (machine direction) at the level of 150, 250 and 350 punches per square cm. needling density have also been examined in this part 2.
