英文摘要	Recently we have successfully produced fine denier PA6 fibers by using additives containing lanthanide compounds. Meanwhile, crystallization and phase transition of PA6 fibers during spinning and drawing processes were investigated. During the spinning process, beta phase crystal could be obtained in as-spun PA6 fibers which were produced with relatively high melt draw ratio, while gamma phase crystal predominated when the melt draw ratio was relatively low. beta phase crystal, whose behaviors are similar with those of gamma phase by FT-IR and XRD characterization, could be transformed to alpha form easily when PA6 fibers are immersed in boiling water. However, gamma phase crystal of PA6 remains unchanged in boiling water. Thus, beta and gamma phase crystals of PA6 can be differentiated by the crystalline behaviors of PA6 fibers after treatment in boiling water. Further experiments demonstrate that the beta phase can also be produced during a drawing process where a phase transformation from gamma to alpha occurs. In other words, beta phase may act as an intermediate state during the phase transformation.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000272032700014&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Chemistry, Multidisciplinary; SCI(E); EI; 10; ARTICLE; 11; 1835-1842; 52
