I believe you also have a certain understanding of potassium hydroxide. Although it has certain toxicity, it also plays a great role in many industries. Among them, it has the general property of alkali. Today, I mainly share with you its application 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(duì)于相對(duì)敏感的顏色，不僅在縮短加堿時(shí)間的同時(shí)，也可大幅度降低染色中產(chǎn)生的色花等許多疵病，提高產(chǎn)品質(zhì)量降低回修，從而節(jié)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(duì)纖維得色不會(huì)造成影響。

1. The slow coloring of soda ash is due to the reduction of the rate of color streaks 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 such as color streaks in dyeing, improve product quality and reduce repair, so as to save costs. If potassium hydroxide is used to replace soda ash for fixation, even if 1 / 10 of sodium hydroxide is used to replace soda ash, enough color supply can be guaranteed. If excessive amount of this product is added in the process of operation, the color of the fiber will not be affected.

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. Due to less use of fixing alkali, it is easy to clean after dyeing, which greatly reduces the white spots caused by unclean washing like alkali after dyeing, and has better warm rubbing fastness and washing fastness than soda ash.

3、染色后減少水洗次數(shù)，節(jié)省了為了使纖維達(dá)到中性的“酸洗”，縮短工藝時(shí)間降低成本。

3. After dyeing, the washing times are reduced, the "pickling" to make the fiber neutral is saved, the process time is shortened and the cost is reduced.

4、由于省去了近十倍的純堿和數(shù)次的水洗，而且染色殘液的COD值低，降低染色廢水的處理負(fù)荷，減輕對(duì)環(huán)境的污染，也為工廠擴(kuò)大規(guī)模創(chuàng)造有利條件。

4. Due to the elimination of nearly ten times of soda ash and several times of water washing, and the low COD value of dyeing residue, the treatment load of dyeing wastewater is reduced, the environmental pollution is reduced, and favorable conditions are created for the expansion of the factory.

氫氧化鉀還適用于各種的活性染料，因此它的適應(yīng)性比較強(qiáng)，具有較高的個(gè)謝亮以及重現(xiàn)性，因此是一種優(yōu)異的染色材料，尤其在低浴比和氣霧染色機(jī)上的優(yōu)越性顯示的更加明顯，大家可以嘗試下。

Potassium hydroxide is also suitable for all kinds of reactive dyes, so it has strong adaptability, high brightness and reproducibility, so it is an excellent dyeing material, especially in low bath ratio and aerosol dyeing machine. You can try it.
