Abstract : coagulation and stretch are two crucial working procedures during precursor fabrication, which play important roles in precursor structure and performance . the fiber tensile strength is affected by concetration, temperature and minus stretch during coagulation, while the fiber structure and performance are obviously influenced by stretch temperature, medium and ratio 文摘:凝固成形和拉伸是原絲生產(chǎn)過程中兩個十分關(guān)鍵的工序,它們對聚丙烯腈原絲的結(jié)構(gòu)和性能有著重要的影響.纖維的拉伸強度在凝固成形過程中受到凝固浴濃度、溫度和負拉伸的影響,同時在纖維的拉伸中拉伸的倍數(shù)、溫度和介質(zhì)等也影響著纖維的結(jié)構(gòu)和性能
