Here is an interesting feature that allows your textiles to change colors in response to changing temperatures around them. The thermochromic quality of our pigment paste allows your printed garment, bed sheet, shoe material, hat, and artificial leather to look more aesthetically appealing.
Also known for its ability to adhere to a wide range of textiles, our thermochromic pigment paste can be used to color cotton, linen, polyester, acrylic fiber and various other blended fabrics.
Good to Know
1. This color-sensitive colorant meets the GB18401-2010 National General Safety Technical Code for Textile Products.
2. Great tinting strength, uniform particle size distribution, and maximum stability are the major benefits of our eco-friendly thermochromic pigment paste.
3. For customers who desire bright colors, they should never miss this out. Presently available are 8 types of colors. Please refer to the color swatch card for more details.
4. The RoHS compliant pigment paste can undergo a reversible change of color when the ambient temperature varies above the minimum level of 31℃
Reference Recipe
The recipes below are offered as a guide only. They are mainly applicable to cotton and polyester.
Formula | Light Color | Moderate Color | Dark Color |
Pigment | 0~1% | 1~5% | 5~10% |
Paste (water-based/glued based) | 100~99% | 99~95% | 95~90% |
Thin (water-based) Printing Paste:
Silkscreen printing with flatbed press, drying (at 100℃ for 3 minutes), baking (at 150℃ for 2 minutes)
Thick (glue-based) Pigment Paste:
Silkscreen printing with flatbed press, baking or blowing hot air on the print surface (at 80℃-100℃), hot pressing (at 130℃-150℃ for 5-15 seconds)
What is said above is a formula for general uses. But it is not useful for every circumstance. Therefore, customers should figure out their specific mixing formula according to individual specifications.
