相信大家对氢氧化钾也有一定的了解，虽然它有一定的毒性，但它在很多行业中也有很大的作用，其中它有碱性，今天主要与大家分享的是它在印染行业中的应用。
　　I believe you have a certain understanding of potassium hydroxide. Although it has certain toxicity, it also plays a great role in many industries, including alkalinity. Today, I mainly share with you its application in the printing and dyeing industry.
　　1,纯碱着色是缓慢的,是由于碱的加入造成色花率大大降低,尤其是对颜色比较敏感,不仅减少碱的时间,而且可以大大减少颜色花染色生产的许多缺陷,有效地提高产品质量和减少维修,节约成本。氢氧化钾代替纯碱的固色，即使在使用1/10量的纯碱代替的前提下也能保证有足够的颜色，在操作过程中不小心加入过量的本产品对纤维的颜色也不会有影响。
　　1. Soda ash is slow in coloring, which is caused by the addition of alkali. It is especially sensitive to color. It can not only reduce the time of alkali, but also greatly reduce many defects of color flower dyeing production, effectively improve product quality and reduce maintenance, and save costs. Potassium hydroxide is used to replace the solid color of soda ash. Even if 1 / 10 of soda ash is used to replace the solid color, enough color can be ensured. In the process of operation, if you accidentally add too much of this product, the color of the fiber will not be affected.
　　2、由于使用了较少的固色碱，所以染色后很容易清洗，大大减少了碱类染料染色后由于清洗而产生的白斑，并具有比苏打水更好的摩擦牢度和洗涤牢度。
　　2. Due to the use of less fixing alkali, it is easy to clean after dyeing, which greatly reduces the white spots caused by cleaning after dyeing with alkali dyes, and has better rubbing fastness and washing fastness than soda water.

　　3.减少染色后的洗涤次数，节省“酸洗”，使纤维中性化，缩短工艺时间，降低成本。
　　3. Reduce the washing times after dyeing, save "pickling", make the fiber neutral, shorten the process time and reduce the cost.
　　4. 因为储蓄的近十倍的纯碱和多次水洗,染色残留COD值低,染色废水的处理负荷减少减少对环境的污染,同时也为工厂的扩张创造了有利条件。
　　4. Because of nearly ten times of soda ash and several times of washing, the residual COD value of dyeing is low, the treatment load of dyeing wastewater is reduced and the environmental pollution is reduced, which also creates favorable conditions for the expansion of the factory.
　　氢氧化钾也适用于多种活性染料，所以它的适应性较强，具有较高的光泽和再现性，所以它是一种优良的染色材料，特别是在低浴比和气溶胶染色机的优势表现得更加明显，您可以试试。
　　Potassium hydroxide is also suitable for a variety of reactive dyes, so it has strong adaptability, high luster and reproducibility, so it is a good dyeing material, especially in the low bath ratio and the advantages of aerosol dyeing machine are more obvious, you can try.
