摘要:
Apparatus for the discontinuous open width dyeing of fabrics having a tank inside of which a dyeing bath is contained in which the fabric (4) is made to pass that unwinds from an unwinding roller (5) to go to a winding roller (6), an expanding equalizer (7) so as to be able to dye even the most delicate fabrics without creases, steam heating means of the dyeing bath, a hood to avoid the dispersion in the atmosphere of the steam that is produced during its use and means for the fine control of the work tension on the fabric, characterised in that at least one of the unwinding or winding rollers (5, 6) comprises first dispensing means (10, 11) of the dyeing bath on the fabric wound on it.
摘要:
Into a machine for the treatment of webs of fabric, preferably scouring and bleaching, there is introduced in combination a wringing unit (6) prior to entry into the treatment vat of the machine, for the application of a vacuum to the fabric (2) to be continuously treated, and an arrangement (11,12) for forced passage of the treatment liquid through the web of fabric (2), in a transverse direction to the web of fabric (2) being treated, from an entry face of the web of fabric (2) to the opposed face of the same, which is the liquid outlet face, during the displacement of the web of fabric (2) in the direction of its longitudinal axis, the passage of the liquid being produced by the action of forced suction by means of a liquid suction system.
