| dc.description.abstract | The best step towards nature conservation is the use of eco-friendly products in our day to day life. As sustainability is becoming more a part of mainstream culture and the masses, eco-friendly home furnishings made out of natural fibre provide a sense of satisfaction to the consumers. Under the umbrella of mountainous region of Uttarakhand state, there are immense fibre yielding plant species growing wildly and have potential to become source of livelihood for local community. Hemp (Cannabis sativa) plant, locally known as bhang is one of the premier fibre yielding plant with lots of good properties. Therefore, present study was planned to utilize hemp fibres for the preparation of exclusive union fabrics for home furnishings with cotton yarns. The hemp fibres were extracted through different retting methods and on the basis of physical properties, most suitable method was selected. The fibres retted with selected method were subjected with different scouring treatments and on the basis of properties and minimum fibre weight loss, the best scouring agent was selected. Retted and scoured fibres were bleached with hydrogen peroxide to improve its colour value. Comparison between the physical properties of fibres obtained from different treatments was done to observe the effect of each processing step on properties of fibre. Processed fibres were combed manually, carded and then hand spun into yarns on Bhageshwari charkha. For the production of union fabrics cotton yarns of 2/20s and 2/60s count were produced from the market. The hand spun hemp yarns as well as cotton yarns were dyed with reactive dye (Procion H) of brown colour. The undyed and dyed, hemp and cotton yarns used for the weaving of union fabric samples were tested for various physical properties. The colour strength and colour fastness of dyed yarns samples were also assessed. Three types of hemp-cotton union fabrics viz. double faced fabric, fabric with extra weft figuring and plain weave fabric with yarn spacing were woven on the handloom with dobby attachment. Estimated cost per meter of fabric was also calculated and fabrics were evaluated by the consumers for assessment of their suitability as home furnishing fabrics. It can be concluded from the results of study that in case of retting methods, chemical retting with NaOH and EDTA was found most suitable method. Acetic acid was found the most suitable scouring agent on the basis of results of fibers properties and less weight loss. The hydrogen peroxide bleaching was found effective in improving colour value as well as fineness of fibres. Hemp yarns were found better in strength as compared to cotton yarns but they were coarser, stiffer and fuzzier in appearance. Colour fastness of dyed yarns against washing, rubbing and sun light was found good. Fabric properties were found to be affected by weave design of fabric samples. Compact weave structures increased the thickness and weight in case of all three woven samples. Fabric samples exhibited good abrasions resistance, tensile strength and tearing strength as well as good to excellent UPF ratings. All fabric sample exhibited poor crease recovery and pilling resistance. Among all fabrics, sample 1 (double faced fabric) showed better properties and appreciated more by the consumers for aesthetic parameters. All fabrics were approved by the consumers as home furnishing fabrics for varied end uses. Consumers’ suggestions were only for the improvement in the texture of all fabric samples. | en_US |
