Effect of Blend Ratio and Relaxation on Structural Properties of Knitted Fabrics

Abstract: The structural properties such as thickness, areal density and tightness factor of a series of polyester/cotton blended yarn knitted fabrics were analysed in an effort to determine physical basis of clothing comfort. Two types of samples were made; first 'before relaxation' and second 'after relaxation', to check whether the relaxation treatment affects these properties or not. The experimental results show that the fabric thickness, areal density, and tightness factor are affected by the fabric relaxation properties. Results observed were significantly affected by the relaxation treatment.
