聚对苯二甲酸乙二酯的复杂波纹卷曲3-4-1，Minohara，茨木，Osaka，567摘要：已知高纵横比的扁平纤维显示复杂的卷曲结构，其中如在海藻中发现的那样，在扁平纤维的边缘处形成波状卷曲。研究了聚对苯二甲酸乙二酯扁平纤维卷曲结构的形成机理。卷曲度随长径比和纺丝速度的增加而增加。该复合卷曲丝的双折射率沿纤维横截面长轴沿着分布较大。当纤维热收缩时，纤维结构的不均匀性导致收缩的不规则性，形成波浪状卷曲。（1992年6月1日）
COMPLEXED WAVY CRIMPING OF POLY (ETHYLENE TEREPHTHALATE) Shinji Ohwaki, Ryouichi Yamasaki, and Masato Yoshimoto Fiber & Textile Research Laboratories, Teijin Limited., 3-4-1, Minohara, Ibaraki, Osaka, 567 Japan ABSTRACT: It is known that the flat fiber of high aspect ratio shows the complexed crimp structure in which the wavy crimp is formed at the edge of the flat fiber as found in sea-weed. The mechanism for the formation of crimp structure in the flat fiber of poly (ethylene terephthalate) was studied in this work. The degree of crimp increased with increasing aspect ratio and spinning speed. The birefringence of this com plexed wavy crimped yarn showed the large distribution along the long axis of the fiber cross section. When the fiber shrank by heat treatment, the structural heterogeneity caused the irregularity of shrinkage which developed the wavy crimp. (Received June 1, 1992)
