发明名称 Splittable fibers having break points, use thereof, and device for manufacturing same
摘要 The object of the invention is to provide splittable fibers (6) which on the one hand are very stable during spinning, i.e., do not dissociate during the entire spinning process and the drawing, and on the other hand after spinning and drawing may be dissociated, essentially completely or even up to 100 percent, into segments (10, 12) or individual filaments. A further object is to keep the technical complexity and energy consumption particularly low. For this purpose, the splittable fibers (6), having at least one break point (8), comprise at least two mutually incompatible polymer components (A, B). At least one polymer component (A) has a lower weight proportion than the other polymer component(s) (B), and the polymer component(s) (A) having the lower weight proportion is situated on and/or in the at least one break point (8).
