氢氧化钾在染色行业的应用

发布来源:http://www.jinhao360.com    更新时间:2021-04-28 点击数:

相信大家对氢氧化钾也有一定的了解,虽然它具有一定的毒性,但是它在许多的行业中也有着很大的作用,其中它具备碱的通性,今天主要与大家分享的是它在染色行业的应用。

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、纯碱上色较缓慢,是因加碱过造成的色花率大大降低,特别对于相对的颜色,不仅在缩短加碱时间的同时,也可大幅度降低染色中产生的色花等许多疵病,提高产品质量降低回修,从而节省成本。由氢氧化钾代替纯碱固色,即使在使用1/10量取代纯碱前提下也能保证有足够的给色量,在操作过程中不慎加入过量的本品对纤维得色不会造成影响。
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 the relative colors, it can not only shorten the alkali addition time, but also greatly reduce many defects such as color streaks in dyeing, improve the product quality and reduce the repair, so as to save the cost. 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、由于固色碱使用量少,故染色后容易清洗,大幅度降低了染色后像碱那样由于洗涤不净造成的白斑,并且有较纯碱更好的温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、染色后减少水洗次数,节省了为了使纤维达到中性的“酸洗”,缩短工艺时间降低成本。
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纯碱和数次的水洗,而且染色残液的COD值低,降低染色废水的处理负荷,减轻对环境的污染,也为工厂扩大规模创造有利条件。
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.
氢氧化钾还适用于各种的活 性染料,因此它的适应性比较强,具有较高的个谢亮以及重 现性,因此是一种优异的染色材料,尤其在低浴比和气雾染色机上的优越性显示的更加明显,大家可以尝试下。
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.
