 Full text | Abstract: The main objective of this paper was to develop a more advanced finishing treatment for the stitch shape regularity and dimensional properties of knitted fabrics. In our previous work, we presented a novel definition of knitted fabric regularity. In the present study we utilised our pervious approach based on Radon transformation analysis to study the effect of different relaxation regimes on the above properties of plain fabrics. We applied various relaxation methods to plain fabrics to make the stitch shape closer to the ideal. The rhythm of stitch shape improvement was evaluated by measuring the deviation of the direction angle of the stitches against the ideal state. The results show that the average fabric irregularity index after ultrasonic-chemical relaxation treatment is better than other relaxation method indices. Moreover the average fabric constant dimensional parameter (Ks) after the above treatment is higher than values reported by pervious workers. Therefore we propose this relaxation treatment as a new relaxation method that is more effective with respect to plain fabric regularity and stability during usage. |
