Abstract
This study aims to find out the dimensional parameter(K) of typical double knit fabrics in fully relaxed state. We used Knapton's method and Starfish method in orders to achieve fully relaxed state of the double knit fabrics. It was found that the dimensional parameter(K) in fully relaxed double knit fabrics on Starfish method were not affected by its density and stitch length, and were kept constant, as they were in single knit fabrics. But the double knit fabrics in Knapton's method did not reach to the fully relaxed state. As result of this study, we suggest that those parameter can be successfully applied for the prediction of the dimensional change of double knit fabrics having tuck or welt stitch.
