Three cotton samples were treated with three sodium hydroxide concentrations at three treatment temperatures. The Digital Fibrograph, Stelometer, and Arealometer were used to measure the effects of treatment temperature and sodium hydroxide concentrations on length, mechanical properties, and fineness parameters. Temperatures and con centrations producing completely mercerized fibers showed the greatest change in fiber properties. Most of the fiber properties showed a greater effect of treatment at the lower temperatures for a given sodium hydroxide concentration.
