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、純堿上色較緩慢，是因加堿過造成的色花率大大降低，特別對于相對敏感的顏色，不僅在縮短加堿時間的同時，也可大幅度降低染色中產生的色花等許多疵病，有效提高產品質量降低回修，從而節省成本。由氫氧化鉀代替純堿固色，即使在使用1/10量取代純堿前提下也能保證有足夠的給色量，在操作過程中不慎加入過量的本品對纖維得色不會造成影響。

　　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、由于固色堿使用量少，故染色后容易清洗，大幅度降低了染色后像堿那樣由于洗滌不凈造成的白斑，并且有較純堿更好的溫摩擦牢度和水洗牢度。

　　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、染色后減少水洗次數，節省了為了使纖維達到中性的“酸洗”，縮短工藝時間降低成本。

　　3. Reduce washing times after dyeing, save "pickling" for neutral fibers, shorten process time and reduce costs.

　　4、由于省去了近十倍的純堿和數次的水洗，而且染色殘液的COD值低，降低染色廢水的處理負荷，減輕對環境的污染，也為工廠擴大規模創造有利條件。

　　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.

　　同時，氫氧化鉀適用于各種活性染料，對各種結構的活性染料都有較高的給色量和重現性；適用于各種設備，尤其在低浴比和氣霧染色機上顯示其獨特的優越性。在筒子紗的生產上能有效解決內外層層差。

　　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.
