Luminous printing is a kind of special printing, which uses luminous powder and adhesives and other additives to print patterns. After being irradiated by other light sources in the Nikko River, the luminous powder stores energy and has a special visual effect in a dark environment. , Emitting yellow-green light. Luminous printed fabrics are generally used in dresses, casual wear, children’s clothing, and interior decoration, or for special work occasions and signs such as public security, fire protection, and transportation.

Influencing factors and precautions of luminous effect
1. The choice of luminous powder
Luminous printing requires luminous materials to be non-toxic, harmless, and non-radioactive, safe for the human body, and not harmful to the environment. At present, there are many types of luminous materials on the market. The rare earth luminous powder has a full light absorption speed, but the afterglow time is long, and the luminous brightness is high.

2. The influence of the particle size of luminous powder
The particle size of the luminous powder is the main factor affecting brightness. The particle size of the luminous powder is generally 200-800 mesh or higher, the smaller the particle size, the better the mesh permeability, the better the adhesion effect, the smooth feel, but the brightness is poor. The larger the particle size, the poor the mesh permeability and the rough feel, but the brightness is high; textile printing and dyeing generally choose 400-600 mesh as the best.

3. The dosage of luminous powder
As the amount of luminous powder increases, the brightness gradually increases. When printing white semi-finished products directly, the amount of luminous powder is 100-150g / kg. If it is a dark semi-finished product printing and dyeing luminous powder, the brightness of the luminous powder is greatly reduced, and the dosage should be increased to 200-300g / kg.
