Clothing dyeing not only aims to achieve the desired color and good dyeing fastness for customers, but also requires a good leveling effect. The so-called level dyeing refers to the uniform distribution of dyes in all parts of clothing. This uniform distribution includes the surface of the dye and the uniform distribution of various parts within the fiber. There are many reasons for uneven dyeing, but there are mainly the following important reasons:

1、 Uneven dyeing caused by the unevenness of the dyed material itself

The unevenness of the dyed fabric itself can be caused by many different factors, for example, cotton fibers often have different dyeing properties due to different maturity, and wool also has different dyeing properties due to different varieties, regions, and parts. Not only that, there are also some cases where the contaminated material is partially contaminated with other substances, such as incomplete washing with water or oil stains, which can cause uneven dyeing.

2、 Uneven dyeing caused by improper dyeing conditions and operations

1. If water-soluble dyes do not dissolve well in the dye solution, are poorly dispersed in the dye solution, and the dye solution is unstable, it may cause uneven dyeing, resulting in color spots, light colors, and other criticisms.

2. When dyeing, the inconsistent concentration of dyes and additives in various parts of the dye solution can cause uneven dyeing.

3. During dyeing, uneven dyeing is also caused by inconsistent temperatures in various parts of the dye solution. Because temperature directly affects the dye uptake rate and percentage.

4. During dyeing, the initial dyeing temperature and heating rate also affect the uniformity of dyeing. If the initial dyeing temperature is too high and the heating rate is too fast, it can easily cause uneven dyeing.

5. When dyeing, too low a dyeing temperature or insufficient dyeing time can also cause uneven dyeing or too light a color.

3、 Uneven dyeing caused by the performance of the dye itself

Although the fibers of dyes have high affinity and fast dyeing rate, their poor diffusion performance can easily cause uneven dyeing.

Guangdong Tiansheng New Materials reminds you that in order to avoid uneven dyeing of clothes, the following measures can be taken:

1. Soak in clean water for 15-30 minutes before dyeing;

2. Gradually heat up during the dyeing process and continuously stir.
