dc.description.abstractThe present study entitled “Construction of knitted fabrics using different blends of oak tasar waste/viscose fibre” was carried out with the objectives, to develop blended yarns from oak tasar waste/viscose fibres, to determine the physical and mechanical properties of the developed blended yarns, to construct the knitted fabrics and to study their physical and mechanical properties and to suggest suitable end uses for the oak tasar waste/viscose blended knitted fabrics. Blending of oak tasar silk waste and viscose fibres was done in the ratio of 60:40, 50:50 and 40:60. The draw frame blending method was adopted and the requisite amount of each fibre was combined on weight basis using worsted spinning system. Yarns of 15 Nm and 20 Nm were spun for each proportion. On the basis of yarn evenness, yarn strength and yarn moisture regain, four optimum blended yarns were selected for the development of fabrics and were knitted on a circular knitting machine. Physical and mechanical properties of the developed fabrics were studied. Subjective evaluation was carried out to analyze the hand values, end uses of the developed fabrics and the performance of developed fabrics in textile industry. It was observed that, 80 per cent judges preferred fabric S3 with excellent smoothness rating, 53.3 per cent judges preferred fabricS4 for softness with excellent rating, 66.7 per cent judges preferred fabricS3 in case of uniformity with excellent uniformity rating.40% OTW:60% viscose blended fabric of 15 Nm exhibited best results for fabric pilling, tensile strength and elongation, snagging resistance, bending length and fabric spirality. Whereas 40% OTW:60% viscose blended fabric of 20 Nm exhibited best results for drapability, GSM, bursting strength and flat abrasion resistance. Also 60% OTW:40% viscose blended fabric of 20 Nm showed best results for elastic properties and thermal insulation. 40% OTW:60% viscose blended fabric of 15 Nm depicted highest rating for smoothness, uniformity, tactile sensation, aesthetic appearance and total hand value. Shrugs, ponchos, stoles and tops and tunics are the most suitable end uses for the fabrics made from 15Nm and 20 Nm blended fabrics while quilt covers, khes/light weight top sheet and bed sheet are the most suitable home textiles that could be made from these fabrics. The cost of the fabric reduced with the reduction of silk proportion in the yarn.en_US
