  • Production of fibres
    Patent number: 4323524
    Abstract: Fibres are produced by centrifugally spinning a formaldehyde resin, e.g. a UF resin, plus catalyst and contacting the spun fibres with a stream of hot dry air to dry the fibres. Cold, humid air is fed to the spinning cup to inhibit premature drying of the resin. The rotation of the cup causes the cold humid air to be thrown out of the cup with the fibres entrained therein. This entrainment serves to retard drying of the fibres while they attenuate.
