Abstract:
Oak tasar silk waste and viscose fibres were blended in three different proportions i.e. 60% oak tasar silk waste: 40 %viscose, 50% oak tasar sik waste: 50% viscose and 40% oak tasar silk waste: 60%viscose for preparing 15 Nm yarn. The yarns developed were tested for physical and mechanical properties. Physical properties such as yarn eveness, yarn hairiness, yarn crimp, moisture regain and whiteness index were analyzed. For mechanical properties yarn breaking force, elongation at break, lea strength and count strength product were studied. It was observed that yarn eveness, moisture regain, breaking force and elongation percent were highest in 40% oak tasar silk waste: 60 % viscose blended yarn. Yarn blended in 60% oak tasar silk waste: 40% viscose ratio exhibited best results for yarn hairiness, whereas, blend ratio 50% oak tasar silk waste: 50% viscose exhibited best results for lea strength and CSP.
