Abstract
The effects of comonomer(DOL),catalyst(CA)addition,and product melt index(MFR)on the spinning performance of polyoxymethylene were systematically analyzes by studying the preparation and spinnability of spinning grade polyoxymethylene.The research results show that appropriately increasing DOL in polyoxymethylene,reducing CA content and increasing product MFR can help improve the spinning performance of polyoxymethylene,with DOL and CA addition ratios of 3％～6％and 2～3 ppm,the MFR is controlled within the range of 8.8～19.8 g/10 min,the spinning performance of polyoxymethylene is optimal,the tensile strength of polyoxymethylene fiber prepared can reach 6.6 g/d.By testing the melt index,crystallinity,spherical morphology and thermal stability of polyoxymethylene samples with different spinning properties,it was determined that the melt index,crystallinity and thermal stability of polyoxymethylene are the key technical indicators affecting its spinning performance,and the spherical morphology is a secondary technical indicator.关键词
