Courses/cm, wales/cm and stitch density do not change with fibre composition or yam twist but increase appreciably with the increasing tightness factor irrespective of the relaxation treatment. Dry-relaxed knits from acrylic-majority yam are more porne to pilling but the incidence of pilling reduces considerably with increasing twist. Fabrics knitted with low-tightness factor exhibit lower area shrinkage.</span>
