【摘要】 本文为采用冻胶纺丝方法制取高强高模聚乙烯醇纤维的初步研究结果。聚合体的分子量(■_w)分别为7.5×10~4和10.1×10~4,制得纤维的强度高达115.7cN/tex,模量为1510cN/tex。文中简要地讨论了纺丝工艺、冻胶纤维的结构、冻胶纤维的拉伸及纤维的力学性能。更多还原

【Abstract】 This paper presents the primary experimental results of preparing high strength andmodulus polyvinyl alcohol fibre using gel-spinning technique.Two kinds of PVA of molecu-lar weight ((?)_W)are used,7.5×10~4 and 10.1×10~4 respectively.The strength of obtainedfibre is as high as 115.7 cN/tex,modulus is 1510 cN/tex.The gel-spinning process,struc-ture of gel-spinning fibre,stretching of gel-spinning and mechanical properties of fibre arebriefly discussed.更多还原
