作者简介：李士云（1974—），女，山东邹平人，工程师，主要从事非棉纤维纺纱技术方面的工作。 Abstract:In order to improve the spinnability of polyamide 6 fiber and solve the problem that it is easy to generate electrostatic in spinning，the performance index of R/P 70/30 14.8 tex blended knitting yarn with 1.67 dtex×38.1 mm polyamide 6 fiber and 1.11 dtex×37.9 mm viscose fiber，the pretreatment of polyamide 6 fiber and the spinning process are introduced.The main process parameters and technical measures adopted in different processes are described in detail，and the quality of bobbin is analyzed.It is pointed out that the moisture regain of polyamide 6 fiber is low，so it is necessary to use antistatic agent to pretreat and moisturize in spinning.In cleaning，combing，drawing，roving，spinning and other processes,we should optimize the process parameters，select the accessories and parts，set the temperature reasonably and keep the relative humidity larger according to the performance of raw materials to ensure the actual moisture regain of polyamide 6 fiber is greater than 8%.At the same time，we should refine the operation management to ensure the good production condition of each process.The quality of R/P 70/30 14.8 tex knitting yarn can meet the requirements and is stable.
