报告英文简介：

High-speed bicomponent melt spinning of polystyrene (PS) and polypropylene (PP) with the composition of 1:1 was performed in this study for the preparation of S/I fibers with 1519 islands in the fiber cross-section. The sheath-core (S/C) fibers and blend fibers of the same composition were also prepared for comparison. Different thinning behavior was observed for the S/I, S/C, and blend fiber spinnings although composition of PP and PS were kept constant. There can be various factors which cause such difference. Those are: (1) effect of flow history in the spinning die on the Barus effect and structure development behavior, (2) effect of the interfacial tension on the Barus effect and thinning behavior, and (3) effect of the development of temperature distribution in fiber cross-section on cooling and solidification behavior of each component. Numerical simulation of the melt spinning process was also utilized for the analysis of the factors affecting the thinning behavior.
