Twisting is the process of reeling the bundles of yarn to skein lacing. It can be achieved by winding two strands of silk into multiple threads. These multiple spools are again used to prepare the warp. The end of the raw silk is tied with cotton thread which helps to find the silk thread end easily during the preparation process for weaving.
A silk warp yarn is made of several single yarns twisted (with a left-hand twist) to the right. Twisting increases the strength of the yarn. Yarns made of reeled-silk threads twisted together are called as thrown silk. Twisting is one of the most important steps in the processing of silk yarns and increases the strength of the yarn considerably and creates compression for packaging. Theses packed bundles of silk yarn are then transported for further treatment like dying, weaving and various other processes.
