Title:
METHOD AND DEVICE FOR PRODUCING SUBSTANTIALLY ENDLESS FINE THREADS
Document Type and Number:
WIPO Patent Application WO2002052070
Kind Code:
A3
Abstract:
The invention relates to a method and a device for producing substantially endless fine threads from polymer solutions, especially spinning material for lyocell, wherein the spinning material is spun from at least one spinning hole or a spinning slot. The spun thread or film is drawn by high-speed accelerated gas flows using a Laval nozzle whose narrowest cross-section is located beneath the point where the spinning material exits. The threads are arranged on a strip in the form of a non-woven or are taken up in the form of a yarn and are subsequently separated in spinning baths by means of solvents
