由河北省科委下达,保定化纤厂承担的“细旦粘胶丝研究”项目,经一年的试纺,各项技术指标已达到项目要求,于1993年12月通过省级技术鉴定。此项目为粘胶丝新品种——66.67dtex/18f纺真丝纤维,应用传统粘胶丝常规纺丝法,经过一年的正交试验,优选出最佳工艺参数,产品质量均达到国家标准。丝绸厂用 By the Hebei Science and Technology Commission, Baoding Chemical Fiber Plant commitment “fine denier viscose research ” project, after a year of trial spinning, the technical indicators have reached the project requirements, in December 1993 passed the provincial technical appraisal . The project is a new type of viscose filament yarn - 66.67dtex / 18f spinning silk fiber. The conventional viscose filament yarn is spun by conventional spinning method. After one year of orthogonal experiment, the optimum process parameters are optimized, and the product quality meets the national standards. Silk factory use
