Continuous lines dyeing

Common concept of our equipments is giving each colourant a dedicated tank, maintained at constant humidity in order to prevent crystallization; the integral timed recirculation down to the dispensing valves and the total drain conic bottom prevents sedimentation and grants thermal uniformity. The dispense is performed in a single tank fixed on the digital scale, with liquor distribution line to the vessels of the spinning/impregnation line. The dosing valves are the same of our other liquid dispensing systems, and their accuracy reaches 0.2 gr over 300 kg batch: for amounts exceeding the scale capacity, the formula is subdivided in equal parts with the same accuracy. The liquor is then pumped directly in the vessel of the demanding dyeing machine: special three-ways valves, pressurized to prevent contamination, select the final destination machine/vessel. At the end of transfer the piping is purged first in the vessel with water, then in the drain with water and bleaching agents. The dispensing software keeps under control the amount of water required for the liquor transfer, plus the top-up volume of the dyeing machine vessel: the transfer of colourants and auxiliaries from the dosing tank and the top-up of volume water is performed at the same time with dedicated lines.
