With increase in weft twist factor, the fabric tenacity initially remained nearly constant and then gradually decreased, the air permeability first increased and then remained nearly constant, the bulk density and intrinsic modulus remained constant up to a twist factor of 81 and then increased, the abrasion resistance gradually decreased, and the K/S<i> </i>value initially increased and then remained nearly constant.</span>
