High-speed melt spinning of sheath-core type bicomponent fibers was performed and the change of fiber structure with increasing take-up velocity was investigated. Four kinds of polymers, were selected and three sets of core/sheath combinations, were studied. The structure of each component in high-speed spun bicomponent fibers was analyzed through the birefringence, wide-angle X-ray scattering pattern and DSC thermogram measurements. The mechanism of the mutual interaction of two components on structure formation in the high-speed spinning of bicomponent fibers was speculated based on the characteristics of the constituent polymers, and it was concluded that the struclure formation of a component having higher temperature-dependent elongational viscosity and high solidification temperature is expected to be enhanced.
