The anionic dye is added to the dyeing bath as a miscible liquid concentrate at a dye addition rate during a controlled dye addition period.
Thus, uneven dyeing and dyeing defects can be prevented when a dyeing process such as a beam dyeing process or a continuous dyeing process is performed, while the strength of the monofilament (30) is appropriately ensured.
The apparatus applying dyeing treatment to textile fabrics has a dyeing bath chamber and a dyeing pipe.
e.g. Production mix in EU: 35 % Semi-continuous, 40 % exhaust dyeing and 25 % Continuous dyeing
e.g. Consumption mix in EU: 30 % Semi-continuous, 50 % exhaust dyeing and 20 % Continuous dyeing
The dye dissolution apparatus comprises the dye transferring device, a weighing platform (300), a dye cylinder (200), a dye auxiliary vat (400) and a dye vat (500).
A coloring composition comprising a polymeric dye, a dye vehicle, and an anionic dyeblocker.
The colorant can be a dye, such as an acid dye.
Also disclosed is a dye-sensitized solar cell using such a dye.
Further, the amount of dye remaining in the dye container may be reduced.
