Introducing the key technique of spinning fine tex yarnson the friction spinner, deals mainly with the technologi-cal parameters of the carding device, conducting tubeand spinning drum for the friction spinning. The experi-mental results show that, the combing effect of pin drumis better than that of garnett; the combing length is a im-portant factor. The form and dimension of the conduct-ing tube influence the rate of fiber straightness and thedegree of fiber orientation. The little angle between theconducting tube and drum axis is good for fiber parallel-ism and straightness. The frictional ratio and the rate ofair flow influence the efficiency of twist.
