Poolin Light-Sensitive Embroidery Thread that actually changes color in the sunlight. An extraordinary new thread designed and tested for today's high-speed embroidery machines. After leaving the light source, the color will disappear and return to its original color. This discoloration effect can be shown repeatedly. The unique color changing effect was tested and proven to last more than 2000 times in and out of the sun (equivalent to the life of a garment). This new technology gives the opportunity to have embroidery designs change from one color to another after exposure to the sun or any UV light sources, which is suitable for trademark, lace, texture, curtain.
