Physical properties studied were the effect of fabric weight and polypropylene proportion in polypropylene-woollenised jute blends on Breaking Elongation (transverse direction) at the level of 150 and 350 punches/Cm2 needling density on Initial Modulus (transverse direction) at the level of (a) 80:20::PP: W. J. blend, and (b) 350 punches/Cm2 needling density of non-woven fabrics. The Box and Behnken Factorial Design and experimental procedures were explained in Part 2. Testing methods revealed the breaking elongation decreases with increasing fabric weight due to better consolidation of the fabric structure with increasing weight due to better consolidation of the fabric structure with increasing weight. Changes in polypropylene content and needling density are covered. The initial modulus in the transverse direction is higher than in the machine direction, possibly due to use of cross-laid web. The initial modulus increase with increase in fabric weight and other findings are summarized.
