EFFECT OF ALKALI TREATMENT ON TENSILE STRENGTH OF VISCOSE WOVEN FABRIC

Alkali treatment of cellulose fibers has a substantial influence on physical and mechanical properties as well as on morphological, molecular properties of fibers and causes changes in their structure and performance. These physical changes were observed and examined by dimensional change, flexural rigidity (in dry and wet state), mass per area, water retention and pick-up, abrasion resistance, tensile strength, elongation at break, and crease recovery following continuous treatment of the viscose plain woven fabrics with aqueous sodium hydroxide solution under varying condition parameters.
