Potassium hydroxide is widely used in different industries, no matter which industry it is used in, its role is very large. The following potassium hydroxide manufacturers will lead you to understand the application of potassium hydroxide in the dyeing industry:
1. Soda-soda dyeing is slow, which is caused by excessive alkali addition. Especially for relatively sensitive colors, it can not only shorten the alkali addition time, but also greatly reduce many defects in dyeing, such as color and pattern. It can effectively improve product quality and reduce repairs, thus saving costs. Potassium hydroxide instead of soda is used to fix the colour. Even if one tenth of the amount of potassium hydroxide is used to replace soda, enough colour can be guaranteed. In the process of operation, the accidental addition of excessive amount of this product will not affect the colour of the fibers.
2. Because of the less use of fixing alkali, it is easy to clean after dyeing, which greatly reduces the white spot caused by washing impurity like alkali after dyeing, and has better temperature rubbing fastness and washing fastness of soda.
3. Reduce washing times after dyeing, save "pickling" for neutral fibers, shorten process time and reduce costs.
4. Because nearly ten times of soda ash and several times of washing are saved, and the COD value of dyeing residue is low, the treatment load of dyeing wastewater is reduced, the environmental pollution is reduced, and favorable conditions are created for expanding the scale of the factory.
At the same time, potassium hydroxide is suitable for all kinds of reactive dyes. It has high color feeding and reproducibility for all kinds of reactive dyes. It is suitable for all kinds of equipment, especially in low bath ratio and aerosol dyeing machine. The difference between inner and outer layers can be effectively solved in the production of cheese yarn.
