Abstract (en)
Fibres are produced by centrifugal spinning a solution of a thermosetting aldehyde resin, e.g. an aqueous UF resin solution, and drying the fibres by contact with a stream of hot, dry, air flowing downwardly from above the spinning cup. To avoid premature drying of the resin solution and fibres, a stream of cold, humid, air is fed to the spinning cup (5), from whence it is thrown, by rotation of the cup, as an outwardly directed stream (11) having the fibres (10) entrained therein. This outwardly directed stream of cold, humid, air is deflected downwards, e.g. by the hot, air stream (16) or by a subsidiary cold air stream, to avoid the formation of a vortex into which the fibres might become entangled.
