Abstract
The effect of sodium acetate to reduce the fiber damage and hardening of acetate fabrics during alkaline treatment is studied. The optimal condition is controlled concentration 2%, at $50^{\circ}C$ for 6 minutes and at $70^{\circ}C$ for 2 minutes through the result of weight loss, shrinkage and tensile strength. Alkaline treated acetate fabrics under optimal condition show softer than untreated acetate fabrics. Alkaline treatment with sodium acetate brings the reduction in hardening and shrinkage in internal fiber of acetate fabric. Also, alkaline treatment with sodium acetate improves the tensile strength of acetate fabrics compared with only alkaline treatment. The moisture regain of acetate fabrics is also improved by alkaline treatment under optimal condition.
