Abstract:In order to solve the problem of“non-spinning”such as low strength，brittle breaking and difficult to spin pure yarn of hollow fiber，the research group of“Key Technology of Design and Manufacture of All-climate Hot and Wet Comfortable Yarn”is established and a mathematical model is established.According to the quality index and fiber characteristics of hollow fiber，the spinning process，carding accessories selection and key points of process design are analyzed.By comparing the yarn indexes of the four trial spinning schemes，it is indicated that it is the ideal structure for spinning blended yarn with 80% hollow fiber and 20% viscose fiber.It is pointed out that production condition of hollow fiber blending is obviously improved，and the proportion for fine count yarn needs to be reduced.Hollow fiber spinning should be carried through the process principle of“reducing hold striking，flexible carding，careful drafting”，and the drawing process should be adjusted.Use high quality hollow fiber and technical adjustment，the finished yarn has bright appearance，few yarn defects and good softness，and all indexes can meet knitting yarn standards，and problem of“non-spinning”of hollow fiber is solved.
Key Words:high moisture-conducting；hollow fiber；strength；pure spinning；blended spinning；knitting yarn
