Abstract (en)

[origin: WO0015895A1] The method for production of carburized fibres in the thermal bonding process of powdered active carbon with thermoplastic fibres relies on the fact that the fibres are mechanically guided in the form of a cable (1) and spread with an active carbon, next in the stretch state they are introduced into suitable high temperature operation which plastifies fibres and causes melting of the carbon into their structure. Next they are taken out of the area of high temperature operation and introduced into the crimping process. The cable of fibres with crimped active carbon taken out from the area of high temperature operation, before the crimping process, is additionally heated up and next mechanically burnished for durability increment of the bonding between the carbon and the fibre structure. The apparatus equipped with a chamber (4) for active carbon spreading with a feeder (5) and the heater (7), has the set of shafts (6) widening the fibres cable (1), which is situated between the chamber and the heater, behind which there is a head (10) used for fibres crimping together with the set of squeezing-receiving shafts (9). The apparatus has additional heater (8) situated behind the heater.
