Potassium hydroxide is a common inorganic base. Its chemical formula is KOH and its molecular weight is 56.1. It is a white powder or flake solid at room temperature. The properties are similar to sodium hydroxide, strongly alkaline and corrosive. The pH of 0.1mol/l solution is 13.5. It is easy to absorb moisture and deliquescence in the air and absorb carbon dioxide to form potassium carbonate. Soluble in about 0.6 parts of hot water, 0.9 parts of cold water, 3 parts of ethanol and 2.5 parts of glycerol, slightly soluble in ether. When dissolved in water, alcohol or treated with acid, a lot of heat will be generated. Moderately toxic, LD50 (rat, oral) 1230 mg / kg.

氢氧化钾是固态氢氧化钠，它的化学性质特别好。广泛应用于农业、工业等方面。今天，小编想介绍它在纺织工业中的应用。我们来看看。

Potassium hydroxide is solid sodium hydroxide, and its chemical properties are particularly good. It is widely used in agriculture, industry and so on. Today, Xiaobian wants to introduce its application in the textile industry. Let's see.

1.可以成型出良好的颜色

1. Good color can be formed

用本产品代替纯碱固色，即使用1/10量代替纯碱，也能保证足够的给色量，少量过量不会影响纤维在操作过程中的着色。

Using this product instead of soda ash for color fixation, that is, using 1 / 10 amount instead of soda ash can also ensure sufficient color giving amount, and a small amount of excess will not affect the coloring of fiber during operation.

2.对染料和设备的广泛适应性

2. Wide adaptability to dyes and equipment

适用于各种活性染料，对各种不同结构的活性染料具有较高的显色性和重现性。此外，氢氧化钾在各种设备上显示出其独特的优势，尤其是低浴比和气溶胶染色机。

It is suitable for all kinds of reactive dyes and has high color development and reproducibility for all kinds of reactive dyes with different structures. In addition, potassium hydroxide shows its unique advantages in various equipment, especially low bath ratio and aerosol dyeing machine.

3.缩短染色时间

3. Shorten dyeing time

氢氧化钾也可称为缓冲固体碱，其电解质较少，溶解时离子强度低。所以在加碱过程中着色较慢，使染料匀染性更好。无论染深色还是浅色，都可以在20分钟左右加入碱，从而缩短染色时间。

Potassium hydroxide, also known as buffered solid base, has less electrolyte and low ionic strength when dissolved. Therefore, the dyeing is slow in the process of adding alkali, so that the levelness of the dye is better. Whether dyeing dark or light colors, alkali can be added in about 20 minutes to shorten the dyeing time.
