Here Are Many Types of Dyes, Which One Do I Call "ladyboy"

Its previous name was basic dye, also known as alkaline dye. And in modern times, it is called cationic dye, which is what I call a "ladyboy" in my eyes.

I have been exposed to dyes for many years because I have been working in dye factories and companies in dye analysis, testing, sampling, color matching, and application. Therefore, I have a special fondness for dyes. The first acquaintance with cationic dyes was about 15 years ago, and at that time, I didn't know much about them, which can be described as seeing the flowers in the mist.

There are currently two main types of cationic dyes widely used. One is the common cationic dye, which truly lives up to its name and exists in solution with a positive charge, that is, cationic; And the other type is a dispersed cationic dye, which is the product of commercial processing of ordinary cationic dyes. It exists as a negative charge in solution, that is, an anion. In my eyes, it is what I want to call a "human demon" because in practical applications, many people have not figured out whether it is "male" or "female".

The characteristic of dispersed cationic dyes is that they dissolve easily with warm water. It is generally recommended to control the water temperature at around 50 ℃, and have low pollution and good uniformity. Their solution is anionic, which allows them to be dyed together with dispersed dyes, reactive dyes, acid dyes, and direct dyes without any problems. Especially with the rise of modified polyester CDP, dispersed cationic dyes have been better applied. Recently, in the fabric market, CDP/PET curtains, sofas, sports shoes, clothing and other fabrics are dyed with dispersed cationic dyes and dispersed dyes in one bath to achieve different style effects.

The biggest misconception in the application of dispersed cationic dyes is that many times, users simply think it is a cationic dye and mix it with ordinary cationic dyes and cationic additives, which inevitably leads to various dyeing problems such as colored spots and spots on the dyed fabric. In addition, when dissolved, its identity is also unclear. Dissolving it with steam or hot water can damage the structure of dispersed cationic dyes and lead to many production problems.

The most famous dispersed cationic dyes currently on the market are the Japanese chemical medicine Kayacryl ED type, the domestically produced SD type, and other manufacturers with different names. When using them, it is important to understand their properties in order to use them better.

For those who are engaged in sample dyeing, when you encounter cationic dyes, please remember that there are both "male" and "female" in this dye. Dispersed cationic dyes are the graceful "girl" that stands tall, because dispersed, reactive, acidic, and direct dyes are all "companions" that they can play with together. This makes dyeing of blended fabrics simple, with many possibilities.

Dyes fill the world with colors, and dyeing work is like a dancer of colors.
