Definitions
- a purpose of the present finding is that of realising a treatment procedure of the continuous dying type in which there is, after the per se known application steps of the dye, a final innovative step which takes care of the optimal and definitive fixation of the dye to the inside of the fibres of the leather itself.
- a further purpose of the finding is that of optimising the continuous dying procedure of tanned leather to produce fixed dyes, with an equal or greater degree of quality with respect to the qualities which leather dyed in a drum possess, making it more environmentally-friendly, thanks to the substantial reduction both in the consumption and in the purifying operation of the water used in the work cycle.
- the procedure according to the finding can be used, as well as for the dying step, also for application operations of retanning agents, of greasing agents and softening agents, which up to now are only possible with the use of drums.
- the leather which has just been dyed which comes out of the dying tank or the coating machine, according to the treatment undergone, that is by immersion or by spreading, is arranged in a vaporisation chamber in which the temperature, pressure and humidity values are appropriately regulated to match that which is most suitable for the different types of dye used in dying, said leather remaining inside said fixation chamber for the time necessary until the dye attaches definitively to the inside of the leather fibres.
- the vaporisation chamber is in a state of slight depression, for which reason the thermodynamic equilibrium between the liquid, arranged at the base of the chamber itself, and the vapour thereof which, expanding, comes into contact with the dyed and still wet leather, attaching the dye to it, is realised at a temperature of less than 100°C.
- vapour which fills the fixation chamber and which comes into contact with the leather, has an acidic pH value.
