ABSTRACT:
A process for producing fibers by spinning a resin by a centrifugal spinning process comprises supplying a resin solution having a viscosity from 50 to 200 Pa.s at the spinning temperature to a whirler plate and ensuring that the resin solution is under a sufficient pressure to completely fill the nozzles of the whirler plate as the fibers are being spun. The process is particularly suitable for producing fibers based on amino resins. In the apparatus the supply line for the resin is preferably located within the driveshaft.
