Is there a phosphorescent paint for textiles?

It is possible to create for example a custom T-shirt with a phosphorescent pattern which appears only in darkness!
Provided to choose the right product:

Among our different ranges of phosphorescent paints or inks,

some are ideal because they are indeed made with water-based resins used in printing of textiles;
these are our water-based paints
– Aero1K
– Moonglo

The Aero1K is a high quality water-based paint, very flexible, waterproof, with a low viscosity. It is very liquid and should be sprayed.

The Moonglo paint is an ink for textile screen printing, for printing on fabric by hand. It is thick and is ideal for
spreading over the screen with a squeegee, then pushed through the mesh of the screen over which you have set up first the stencilling project.

Aerosols are also suitable
as they create a film with good flexibility, and provide good durability during machine wash

Moreover, we can manufacture ultra flexible (at 1800) and ultra resistant (Cel-Glow two-component paint) paints
This paint is produced only on special order with a minimum of 1.3kg

Both inks/paints are colourless. They give a phosphorescent effect only over a light background. Over a red or black background for example, the effect will be close to zero.
We propose 8 various phosphorescent colours on the webshop phosphorescent.fr

Phosphorescent paints require a certain number of passes or a certain thickness to give good gloss; indeed, the thicker the dry film is, the more the phosphorescent paint will glow brightly and for a long time.
Note: if the film is too thick, it has a stiffening effect.

Are the colours resistant to the washing machine?

Everything depends on the number of cycles, the washing temperature and the detergents used.
Here is what we can estimate:
Moonglo: 10/20 cycles with baking
Aero1k: 25 cycles
Aerosol: 25 cycles
Cel-Glow: 100 cycles
