Description

Technical Field

[0001] The utility model belongs to the technical field of alkali-free dyeing equipment, in particular to an environmentally friendly alkali-free dyeing material tank. Background Art

[0002] In order to improve the color fixing effect of cotton fabrics, the dyeing process of the prior art adopts a one-salt-three-alkali process, in which salt needs to be added twice, and the dye is added after the two salt additions. Subsequently, during the dyeing process after the dye is added, soda ash needs to be added three times to maintain the pH value of the dye solution at about 11. The multiple additions of soda ash make the human-machine interaction time too long, and the equipment energy consumption is high. There are many process steps, the discharged dye solution contains a large amount of soda ash, and the cost of wastewater treatment is high; the existing low-salt-low-alkali or salt-free low-alkali dyeing method improves the above shortcomings, but in order to ensure the dyeing rate of the reactive dye, it is usually necessary to increase the temperature of the dye, and it is necessary to heat it to 50-70°C in 30 minutes at a starting temperature of 25°C and keep it warm for 30 minutes. In order to reduce the energy consumption of the equipment, the dye vat is usually heated by a uniformly supplied steam. However, due to the constant temperature of the steam, it is difficult to quickly heat the dye to 50-70°C within 30 minutes during the heat exchange and heating process of the dye vat, thereby reducing the dyeing rate of the reactive dye.
