Abstract:In order to solve the problems of monotonous color，single fabric style，and dyeing pollution of traditional denim yarns，from the denim yarn fancy design，the scheme design of five kinds of double-section variable fancy denim yarns spinning on the dual openning rotor spinning single-head test machine are elaborated by using black and white viscose fiber and changing the proportion of different color fiber components.The denim yarn of color style with grey and black is selected，and the orthogonal test based on three factors，namely the speed of the openning roller，the speed of the rotor，and the twist of the resultant yarn is designed to compare the properties of yarns spun at different test levels，and the best spinning process combination and weaving process are selected.It is pointed out that under the conditions of 7.5 kr/min to the speed of the openning roller，50 kr/min to the speed of the rotor，and 65 twist/(10 cm) to the twist of the yarn，the quality of the denim yarn is better and the fabric has obvious grey and black denim style.The spinning mode that used the dual openning rotor spinning technology，changing raw material components and alternating ratio is adopted.In this spinning mode，the color of the denim yarn is directly designed，the production is convenient and efficient，and the process is environmentally friendly.By increasing the changing proportion and changing times of colored rawmaterial components，the multi-section and gradually changing fancy denim yarn can be spun.
