Abstract:In order to improve the yarn strength of C 36.4 tex+2.0 tex elastic yarn，the influence factors of fore-spinning process，spinning process and automatic winding process on yarn strength are analyzed in detail.It is stated that the problems of uneven cotton blending，control of short fiber generation，and avoid uneven and light quality of drawing sliver in final drawing process should be solved in the fore-spinning process.The twist unevenness of the spinning yarn should be strictly controlled in the spinning process.The joint work should be focused on in the automatic winding process.The solutions such as temperature and humidity management in each process have been strengthened at the same time.It is pointed out that after the technical breakthrough，the strength range of the elastic yarn is reduced to 80 cN，the minimum strength is increased to 470 cN，the average strength of single yarn is more than 550 cN，and the CV value of strength reaches a good level of 6%~8%.
Key Words:elastic yarn；yarn strength；strength range；cotton blending；short fiber；quality unevenness；twist
