Abstract:
PURPOSE: To obtain a melamine-formaldehyde resin fiber having a high level of strength, homogenous elasticity and low flash point by feeding the resin solution to a rotating plate in a specified condition and centrifugally spinning the resin. CONSTITUTION: A method for producing fibers has a centrifugal spinning process comprising supplying a resin solution having 50-200 Pa.s viscosity at a spinning temperature to a rotating plate 1. An enough pressure to completely fill a nozzle 9 of the rotating plate 1 with the resin solution, normally 10-80 bar, preferably 30-55 bar, is added to the solution within the plate.
