Abstract (en)

[origin: DE19800297C1] The invention relates to a method for producing fibrous materials from thermoplastic materials, wherein thermoplastic material is molten and fed into a rotating reactor (5) to form a molten film and the fibers are formed on and stretched out along an open edge of the reactor. The fibers are formed on the reactor edge without using nozzles or ducts that are susceptible to clogging so that the rotating reactor (5) is heated in such a way that the molten film has a temperature close to decomposition temperature of the thermic plastic materials and the reactor (5) is rotated on the edge at an orbital speed of no less than 10 m/s.
