| dc.description.abstract | The research was planned to study the effect of four essential oils on cotton fabrics applied through four treatment methods i.e. direct, microencapsulation, resin cross-linking and combination. To achieve the objectives proposed in research plan, out of thirteen, four essential oils i.e. geranium, lime, palamarosa and peppermint were selected on the basis of preferences for aroma and therapeutic effects by 25 respondents for application on the selected woven and knitted cotton fabrics. Different treatment variables i.e. padding bath components, material to liquor ratio, treatment time, drying temperature and time, curing temperature and time were optimized on the basis of bending length, flexural rigidity and crease recovery. In microencapsulation and combination method, in addition to performance properties, presence of microcapsules and aroma durability to washing were also assessed. After application of essential oils using optimized conditions on both the fabrics, Scanning Electron Microscopic (SEM) analysis and aroma durability in terms of retention and intensity of aroma to washing, abrasion, ironing and sun-drying was done. Effect of aroma treatment on change in fabric properties regarding fabric count/stitch density, thickness, weight, bending length, flexural rigidity, crease recovery, bursting strength, air permeability, tearing strength, tensile strength and elongation were examined. Effect of aroma treatment on texture and whiteness was also investigated. Different variables of microencapsulation method for preparation of microcapsule gel i.e. ratio of oil: gum: gelatin 1:2:4 for lime, palmarosa and peppermint oil, 1:4:4 for geranium oil, at 50°C temperature, initial pH 4.5 and final pH 9.0 for geranium, lime and plamarosa oil, 4.0 and 10.0 for peppermint oil were optimized. Proportion of padding bath components were optimized as 50:3:15 microcapsule gel: softener: binder for microencapsulation, 6 percent citric acid for direct method, resin cross-linking agent i.e. BTCA 12 to13 g/l for woven and knitted fabric with proportion of 2 to 4 g/l sodium hypophosphite for resin cross-linking method. At MLR 1:20 with 30 minutes of treatment time, both the fabrics treated with all the four essential oils exhibited better performance properties. The drying temperature (80° and 90°C), duration (2, 3 and 4 minutes), curing temperature (110°C) and curing duration (30 and 60 seconds) were selected for treated fabric on the basis of improvement in the performance properties. Maximum aroma durability in terms of retention and intensity was observed in combination method followed by microencapsulation, resin cross-linking and direct method after washing, abrasion, ironing and sun-drying of aroma treated woven and knitted fabrics. Fabric count (woven), weight and thickness increased in both the fabrics treated with all the essential oils by all the treatment methods. Bending length and flexural rigidity were also found to be increased but at an acceptable level. Stitch density increased in knitted fabric treated with all the essential oils by microencapsulation and combination method whereas decreased in direct and resin cross-linking method. Crease recovery of all the treated fabrics decreased when aroma treatment was given by microencapsulation and direct method and increased in resin cross-linking and combination method. Air permeability and tearing strength of the woven and knitted fabric decreased however, tensile strength and elongation decreased in woven and bursting strength decreased in knitted fabric with all the essential oils by all the treatment method but to an acceptable level. Texture of both the fabrics was not affected much. There was not much difference in whiteness of both the fabrics treated with geranium and peppermint oil but samples treated by lime and palmarosa oil give some difference in whiteness as indicated by whiteness index values. It was concluded that all the four essential oils can be effectively used without affecting the comfort and performance of the treated fabric to give aroma treatment by direct, microencapsulation, resin cross-linking and combination method as per aroma durability requirement of end product. | en_US |
