氢氧化钾在染色行业的应用!

发布来源:http://www.jinhao360.com    更新时间:2019-03-01 点击数:

氢氧化钾用途非常广泛,它应用在不同的行业,不管应用在哪一行业它的作用都非常大,下面氢氧化钾厂家就带领大家了解一下氢氧化钾在染色行业的应用:

  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、纯碱上色较缓慢,是因加碱过造成的色花率大大降低,特别对于相对敏感的颜色,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,有效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. 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. 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. 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. 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.
  同时,氢氧化钾适用于各种活性染料,对各种结构的活性染料都有较高的给色量和重现性;适用于各种设备,尤其在低浴比和气雾染色机上显示其独特的优越性。在筒子纱的生产上能有效解决内外层层差。
  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.
