When choosing color masterbatch, there will be some problems that need everyone’s attention. These problems are usually the ones that we will ignore. For these problems, the color masterbatch manufacturers will summarize some knowledge for everyone, and hope that everyone can learn from them. This knowledge.

　　 color masterbatch is also a commonly used masterbatch for functional dyeing. It is also different in selection from other masterbatches. Where is it specifically reflected? Let's give you a detailed introduction to these issues.

　　Different masterbatches have different performances when selecting pigments. The following is an introduction to how to choose pigments for masterbatches:

　　The pigment used in the heat-resistant masterbatch is basically required to withstand the temperature during the production of polypropylene fiber and keep its performance stable. The temperature resistance is generally required to be above 270~280℃.

　　The pigment used for dispersible masterbatch should have good dispersibility and be evenly dispersed in the masterbatch, and the dispersant used should not reduce the quality of polypropylene fiber. Otherwise, it is impossible to produce high-quality dope-colored fibers, and the operation is also unstable, and it is easy to break or produce abnormal fibers when the fibers are drawn.

The coloring of 　　brightness polypropylene stock solution has many uses. Among them, it is used for bed cover base fabrics and knitted fabrics, which require bright colors. Because organic pigments are brighter and brighter, and easy to color, organic pigments should be used for the above purposes.

Under the action of light, some pigments have photosensitivity, which makes colored fibers fade and brittle. The light resistance of pigments is basically related to their chemical structure. Therefore, pay attention to the light resistance and light resistance of pigments when making masterbatches. When the pigment needs to be used, you can consider adding ultraviolet absorbers.

　　The pigment used in the stable masterbatch must have excellent stability to the colored polypropylene fiber. It means that the pigment will not react with the fiber when the colored fiber polymer is exposed to heat, light or high temperature for a long time, and new chemical groups are formed to make the polymer performance low.
