Researchers determined the effects of yarn count, tightness, takedown tension, and spreader width on the dimensional stability of double knit fabrics in the dry relaxed state. Experimental materials included rib and interlock double knit fabrics manufactured from combed hosiery yarn in counts of 28, 32, 36, and 40. Duncan's Multiple Range Test evaluated the effects of courses per inch (CPI), wales per inch (WPI), and stitch density. CPI, Fabric density, CPI, WPI, and stitch density increased with the tightness factor. WPI and the number of holes increased with increases in fabric takedown tension, whereas CPI and the number of holes increased with increases in spreader width. 6 refs.
