Updated: 2020/3/2 20:54:00

Abstract: The paper discusses the influence of the combing process on spinning quality of cottontype lyocell fiber, and analyses the necessity of lyocell fiber combing. Under the same spinning process parameters, the cotton-type lyocell fibers were carded and combed respectively to produce 14.6 tex carded yarn and combed yarn, and the quality indexes of card sliver, combed sliver and yarn were tested. The results showed that the combing process could eliminate 50% neps and impurities in sliver and 30% lyocell staple. Compared with lyocell carded yarn, the IPI value of lyocell combed yarn decreased by 62%, the CV value of yarn evenness declined by 17%, and the breaking strength and breaking elongation rate of yarns were improved significantly.
