The Design and Manufacture of Profiled Multi-channeled Hollow Polyester Fibers
A Numerically Controlled Electrical Discharge Machining (EDM) System was developed for the production of spinnerets that can be used to manufacture profiled multi-channeled hollow fibers with noncircular cross-section full of 16/17 holes of circular shapes. Four spinnerets of different slit shape were made, and four hollow fibers were produced accordingly. The first trial with I-type slit failed due to the adhesion between melt polymer jets when they were extruded from the spinneret and also the melts didn't spread well. In the second trial, fibers were obtained from a spinneret with both "C" and "I" slits. Again it failed to produce results expected, as the 4 holes in the center of a fiber appeared to be larger than the other 12 holes. The third trial that produced fibers from a spinneret with "C" slit was a success. They were fibers with 15 holes of almost the same size. This technique was then adopted for mass production. This time silver electrode was used as copper electrode couldn't achieve the goal. In the mass production, profiled hollow fibers were obtained with 17 holes of similar dimensions, uniformly distributed in the cross-section. Porosity of the fibers reached 20.2 %. It is now clear that this technique is useful for manufacturing highly porous profiled fibers with specially designed features.
