Exit Bending Phenomena by the Interface Movement in Bicomponent Fiber Spinning

접합형 이성분 섬유방사에 있어서 계면운동에 의한 다이출입에서의 휨현상

A bending phenomenon at the die exit by the interface movement was theoretically analyzed in bicomponent fiber spinning. The shape of interface was determined as a function of residence time of polymer in die. The exit bending angle was derived from the shape of interface, and was determined as functions of the fractional volumetric flow rate and the phase portion after swelling.
