SITRA, UNDP, and the Indian Ministry of Textiles are developing technologies and machinery for the spinning of jute and cotton blend fibers. Spinning jute/cotton blends with cotton spinning machinery results in yarns that are weaker than 100 percent cotton and have a slightly lower level of abrasion resistance. Jute/cotton yarns spun on ring spinning machines have excessive fiber shedding. Jute fibers in the 2/1 and 3/1 range cannot be spun using cotton spinning machinery. Excessive shedding, which results from the low interfiber cohesion of jute fibers, can be reduced through wet spinning, in which roving can be passed through a trough of water or chemical solution before the drafting zone. Friction spinning is another way to reduce excessive shedding. Friction is applied at the final stage of spinning when the fiber ribbon diverges from the front rollers of the ringframe for twist insertion. Two moving feed systems and three roving feed systems for jute/cotton blends have been developed to increase the strength and abrasion resistance of jute/cotton yarns.
