Improvement of Tensile Strength of Viscose Woven Fabric by Applying Chemical Finishes

This research work was endeavored to improve tensile strength of viscose woven fabric by using chemical finishes like water repellent finishes with cross linking agent and softener. In this work, 100% viscose woven fabric was used and different types of samples were prepared by treating water repellent finishes, cross linking agent and softeners. The sample was investigated by tensile strength test (ASTM D5034), spray test (AATCC–22), water vapor test (cup method) and moisture regain test (ASTM D2495 oven dry method). Eight types of recipes were used in this research. For the variation of C6-fluorocarbon the sample code-B (C6-fluorocarbon 60g/l, cross-linking agent 15 g/l and softener 10g/l) showed better result in tensile strength and water spray test. Taking the amount of C6-fluorocarbon (60g/l) as constant and making variation cross linking agent which reached a conclusion that, sample-B1 (C6-fluorocarbon 60g/l, cross-linking agent 05g/l and softener 10g/l) showed better result for wet tensile strength, water spray test and moisture regain but showed less water vapor permeability. From this experiment it was evident that recipe which belongs to sample code B1 is suitable for improving the tensile strength of viscose fabric.
