This article analyzed the effects of pre-and post-spinning drawing processes on the properties and spinning speed of ultra-high molecular weight polyethylene(UHMWPE)fibers during production.The influ-ence of the post-spinning cold drawing ratio on the strength and modulus of the fibers were investigated,fol-lowed by the study of the effect of the pre-spinning drawing ratio on the strength,modulus,spinning speed,and gel fiber shrinkage of the fibers.The results indicate that increasing the cold drawing ratio during post-spinning ef-fectively enhance the fiber strength.In addition,increasing the pre-spinning drawing ratio facilitates the precipita-tion of solvent oil and improves the production speed.These results provide theoretical and practical basis to in-crease fiber production and improve the quality of the fibers.
