相信大家對氫氧化鉀也有一定的了解，雖然它有一定的毒性，但它在很多行業(yè)中也有很大的作用，其中它有堿性，今天主要與大家分享的是它在印染行業(yè)中的應用。
　　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,純堿著(zhù)色是緩慢的,是由于堿的加入造成色花率大大降低,尤其是對顏色比較敏感,不僅減少堿的時(shí)間,而且可以大大減少顏色花染色生產(chǎn)的許多缺陷,有效地提高產(chǎn)品質(zhì)量和減少維修,節約成本。氫氧化鉀代替純堿的固色，即使在使用1/10量的純堿代替的前提下也能保證有足夠的顏色，在操作過(guò)程中不小心加入過(guò)量的本產(chǎn)品對纖維的顏色也不會(huì )有影響。
　　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、由于使用了較少的固色堿，所以染色后很容易清洗，大大減少了堿類(lèi)染料染色后由于清洗而產(chǎn)生的白斑，并具有比蘇打水更好的摩擦牢度和洗滌牢度。
　　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.減少染色后的洗滌次數，節省“酸洗”，使纖維中性化，縮短工藝時(shí)間，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. 因為儲蓄的近十倍的純堿和多次水洗,染色殘留COD值低,染色廢水的處理負荷減少減少對環(huán)境的污染,同時(shí)也為工廠(chǎng)的擴張創(chuàng )造了有利條件。
　　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.
　　氫氧化鉀也適用于多種活性染料，所以它的適應性較強，具有較高的光澤和再現性，所以它是一種優(yōu)良的染色材料，特別是在低浴比和氣溶膠染色機的優(yōu)勢表現得更加明顯，您可以試試。
　　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.
