ABSTRACT:
For the fixation of dyes and other chemicals in textile fibres, however formed or combined, such fibres are conveyed through a closely confining tube located between electrodes by which a radio frequency energy field is created in the tube, the packing of the tube with such fibres being sufficiently dense to ensure that, when heated by the energy field, the tube and its contents form a partially self-sealing pressure chamber whereby the rate of reaction of the dye or chemical on the fibres is accelerated. Various embodiments of apparatus for the performance of such a fixation process on fibres of different forms and combinations are also shown.
