The printing process is a process of printing patterns on textiles with effect pigments such as polyester glitter powder and mica powder. In the winter, for those who have been engaged in the printing industry for a long time, the precautions that need to be taken must be kept in mind. This article is dedicated to friends in the printing industry, so that they can take less roads in printing.

Winter printing must strictly control the process conditions.

Sizing → printing → drying → steaming → washing.

Do a seasonal test.

The following are problems that are prone to occur in winter water slurry.

Problem Appear:

1. The water slurry is easy to freeze and lose color, poor elasticity and fog cloud state.

2. Self-crosslinking performance is slow, prone to dry and wet.

Solution:

1. The slurry should be stored at above 6 °C.

2. The temperature of the printing work space is above 12 °C.

3. It is forced to cross-link dry by using a drying tunnel or a pressing machine. The natural drying does not conform to the standard printing process, and the baking should be strengthened in winter.

4. Strictly control the PH value (7.5-8) during beating, reduce the amount of thickener and the use of plastic additives.

5. High-grade printing is properly added to the diplomatic joint colloid.

6. The frozen slurry should not be mixed into the new slurry.

There are also rubber cement and photo-sensitive resist, which will have some inevitable problems in the winter, we will share it with you in the next article, thank you for watching, if you have any questions, please feel free to contact iSuoChem!
