Abstract
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.
Highlights
From textiles point of view, cotton and viscose both are important cellulosic fibers mostly used in modern textile manufacturing industry [1]
Tensile Strength Test for C6-Fluorocarbon Variation The tensile strength test determines the strength of the fabric
In case of higher concentration of C6-fluorocarbon, the tensile strength decreases. This is due to the fact that, water repellent chemicals form cross link with viscose free O-H group in the amorphous region, it makes stiff of the viscose fabric
Summary
From textiles point of view, cotton and viscose both are important cellulosic fibers mostly used in modern textile manufacturing industry [1]. The properties of those fibers represent the same because the regular viscose fiber ( lower water absorption), to high wet strength [7] These fibers square measure usually mixed with cotton fibers. Water-resistant treatment helped in reducing the molecular barrier round the individual fibers that lowered down the crucial physical phenomenon of the fibers [11] This reduced physical phenomenon of viscose material helped in raising its wet strength [12]. It is prepared from fatty alcohol alkoxylate and organic phosphorous compound
