The present study aims to the use of carboxymenthyl cellulose (CMC) improving the ability of fiber in the dyeing process. Cellulose was extracted from banana leaves by NaOH and then modified by reacting with chloroacetic acid to obtain the carboxymenthyl cellulose. The effect of carboxymenthyl cellulose contents on the mechanical properties and dye absorption were also investigated. Then, CMC were blend with polypropylene (grade 561R) at 1%, 3% and 5% by weight ratio. The fibers were obtained from single screw extruder. The results show that the mechanical properties of the product decreased when increased the amount of CMC in the fiber product. After dyeing, the dye however were absorbed by the CMC-PP fibers more than the original PP fibers. The absorption of dye on the CMC-PP fibers increased significantly with the CMC ratio.
