The process of blending involves the mixing of two different fibers to achieve the desired percentage. Various compositions, lengths, diameters, or colors may be intermingling to produce a blended yarn in a ring spinning system. This system entails the combination of different fibers lots into a homogeneous mass before spinning the mass into a staple fiber yarn. Typically, BJRI Tossa Pat-8 (Robi-1) and cotton fibers are combined to create jute-cotton blended yarn. Jute can be utilized in various ways, which is one approach to blending yarn. The jute-cotton blended yarn was produced in a ratio of 30% and 70%. Both jute-cotton blended yarn and totally cotton yarn were produced on a cotton spinning line using a ring frame. The physical characteristics of both yarns, such as count, yarn Lea strength, and CSP were measured. The average count of fully cotton yarn and jute-cotton blended yarn was found to be roughly equal at 12.16 and 11.82, respectively. However, the yarn lea strength and CSP of both samples, which are significantly different from one another, were 232 lb, 140 lb, and 2835, 1670, respectively. Along with entirely made of yarn, blended yarn also exhibits consistency in terms of CV%, SD, and PMD. This study compared the physical characteristics of both yarns after Robi-1 was first introduced for the blending process with cotton to produce a jute-cotton blended yarn.
