2. Pre-spray treatment liquid

The clothes made of pure cotton need to be pre-treated before being fixed on the printing machine platform. The pre-treatment solution for light-colored pure cotton fabrics and the pre-treatment solution for dark-colored pure cotton fabrics are different. The pre-treatment solution for light-colored fabrics is mainly used to increase the brightness of the pattern; the pre-treatment solution for dark-colored cotton fabrics is used to chemically react with the white ink used for primer, so that the white ink can be firmly adsorbed on the dark pure color. on cotton fabric. The processing tools are diversified, and you can use professional spray coating equipment or electric watering cans.

If the temperature is too low, the color fastness is not enough, or the time is too long, and it is easy to cause damage to the fabric. If the time is too short, the pattern will be damaged. It will also wash off. Therefore, it is necessary to accurately grasp the time and temperature of the fixing color in order to make the best effect of the printing.
