Effects And Requirements Of Dyeing Auxiliaries On Clothing

In recent years, the rapid development of textile industry has greatly increased the demand for dye-based textile chemicals. The mutual dependence of dye-based industry and textile industry means that China's dye-based industry has a huge market prospect.

Printing and dyeing auxiliaries can be divided into printing auxiliaries and dyeing auxiliaries. Dyeing auxiliaries are chemical substances that can improve the dyeing effect and stability of dyes. They are often used in the dyeing process of textiles and clothing.

Common dyeing auxiliaries are as follows:

1. Coloring agent: used to improve the affinity and permeability of dyes, so that they can better penetrate into the interior of fabric fibers.

2. Reducing agent: used to reduce the dye to soluble reduction color base, in order to improve the dyeing effect and stability.

3. Dispersing agent: Dispersing agent can help disperse the dye in the water, prevent the dye from clumping together, and make the dye more even. Dispersing agent can also improve the dyeing speed and dyeing effect.

4. Softener: most have fragrance, aromatic agents, dyes are mostly petroleum derivatives, containing benzene, if the manufacturer uses poor grade of raw materials will also cause irritation to the skin. Fabric softeners act like a uniform protective film on the surface of fabric fibers. As softeners adsorb on the surface of fabric fibers, the coefficient of friction between fibers decreases.

5. Antioxidants: Antioxidants can protect the dye from oxidation, thus improving the stability of the color after dyeing.

6. pH regulator: pH regulator can adjust the pH in the dyeing process, making the dyeing more uniform and stable.

7. Enzyme: Enzyme can reduce the surface hairiness of cotton fabric and make dyeing more even.

So what are the functions and requirements of dyeing auxiliaries in the application of clothing?

First of all, dyeing auxiliaries can improve the affinity and dispersion of the dye, so that it can be more evenly distributed on the fabric fiber, so as to obtain better dyeing effect. And the dyeing speed and uniformity can be improved to make the dyeing process more efficient and controllable.

In addition, it improves the properties of light resistance, water resistance and friction resistance, so that the color after dyeing is more stable and lasting.

There are the following requirements in use:

1. Harmless to human body: clothing dyeing additives must conform to the relevant national laws and regulations, harmless to human body, will not cause allergic and toxic reactions.

2. Good stability: dyeing additives must be able to improve the performance of light resistance, water resistance, friction resistance and so on, so that the color can be stable for a long time after dyeing.

3. Easy to use and handle: the dyeing agent must be easy to use and handle, will not adversely affect the dyeing process, and easy to clean and recycle.

4. Environmental protection: dyeing additives must meet the requirements of environmental protection, will not cause pollution and harm to the environment.

In general, the effect of dyeing auxiliaries is to establish better interaction between dyes and fibers, improving dyeing effect and stability. Different types of dyeing AIDS have different functions in the dyeing process, according to the specific dyeing conditions and requirements to choose the appropriate dyeing auxiliaries is very important.
