Precautions for the dyeing process of the dyeing machine

1. Bath ratio; 2. Heating rate; 3. Pump pressure; 4. Corrosion of stainless steel body by sulfuric acid, hydrochloric acid, sodium hypochlorite, etc.; 5. Pay attention to daily maintenance, decalcification, refueling, etc.;

There are too many types of dyeing machines. You don’t need to know them all. It depends on what you want to dye. There are many types for each specific purpose.

1. Control of bath ratio. Generally speaking, the quality of dyeing cannot be isolated from the bath ratio. More importantly, it depends on the design of the whole machine and its mechanical controllability. From the perspective of dyeing and finishing, whether the liquor ratio is set properly or not depends on the overall dyeing quality.

2. Warming up, keeping warm and cooling down: This question depends on the specific product, and the quality of the dye used in dyeing.

3. The control of PH value is when using disperse dyes to dye polyester and its blended fabrics. Everyone knows that about 98% glacial acetic acid 0.6ml/L is used to adjust the PH value to 5±0.5, but sometimes it is ignored. Hold on! Prevent chromatic aberration and discoloration.

4. Chemical materials and additives, the materials and additives of disperse dyes used to dye polyester are very particular.

5. Level dyeing is the core of dyeing and finishing engineering.
