Experimental Results of the Bending Phenomenon at the Die Exit in Bicomponent Fiber Spinning

The bending phenomenon at the die exit was analyzed in bicomponent fiber spinning. The exit bending angle was expressed as funtions of the melt viscosity ratio and melt elastisity ratio of the two components. It was increased with both the melt viscosity ratio and the melt elasticity ratio of the two components. These were compared and discussed with the experimental results obtained by the bicomponent fibers of four nylon-polyester combinations.
