Influence of blend ratio on physical properties of oak tasar silk and acrylic blended spun yarn

In this study an attempt was made to utilize the oak tasar silk spinning waste through blending it with acrylic fibre and prepared yarn in mechanised spinning system. The oak tasar silk and acrylic blended yarn were prepared on ring spinning machine with five different blend ratios viz. 100:0, 60:40, 50:50, 40:60 and 0:100. The prepared yarns were of medium to fine yarn count. Yarn Physical properties of yarns, unevenness and imperfections were studied and statistically analysed. Results revealed that the 100% acrylic and 50:50 tasar acrylic blended yarns had better properties as compared to 60:40 and 40:60. The addition of acrylic fibre content improved the physical properties, unevenness and imperfection of the blended yarns.
