  Abstract:In order to improve the spinnability and utilization rate of regenerated cotton fibers，the morphology and properties of black regenerated cotton fibers and white raw cotton fibers are introduced.Based on the principle of dual openning rotor spinning technology，two kinds of fibers are used as raw materials to spin regenerated cotton/cotton denim yarn with a blending ratio of 10/90～80/20 at total of 8 levels.The key points of each process of spinning regenerated cotton/cotton blending yarn are analyzed，and the properties test and denim style test are carried out.It is pointed out that the spinnability of regenerated cotton can be significantly improved after the fibers of 50% regenerated cotton and 50% raw cotton are blended into slivers in the raw material stage.When the blending ratio of regenerated cotton fiber is more than 30%，the breaking strength index of yarn decreases obviously.When the blending ratio of regenerated cotton is 25%，the appearance color and quality of the yarn are the best，and the appearance style and visual effect of the fabric are close to the traditional gray-black denim fabric.
Key Words:dual openning rotor spinning；regenerated cotton fiber；blending ratio；denim yarn；yarn properties
