The study focuses on the mix compatibility of cotton and bohemeria fiber for the production of yarn. The Bohemeria fiber used for the study was by chemical degumming. By the chemical degumming from 1,500gm decorticated boehmeria 1,370gm of bohemeria fiber extracted which 91.3% fiber yield. The color of the extracted fiber is reddish yellow due to the presence of lignin, pectin, wax and other unwanted materials. To make the color of the extracted fiber compatible to cotton, bleaching using H2O2 was carried out and the converted bleached fiber into staple length by chopping. To facilitate the mixing of the bohemeria and cotton fiber; first Manual opening carried out and Further opening using waste feeder continued to open gently and to form homogeneous mix. In the mix Component ratio of 35% Bohemeria and 63% cotton was used. The mixed fibers were opened to individual fibers on carding. Finally 33Nm yarn is produced on rotor spinning machine. The Yarn has Tenacity of 10.822g/tex, elongation of 5.026% and breaking load 298.9gm.
