The luminescent fiber does not require any coating treatment, and its glowing body can withstand long-term sunlight exposure. Under the harsh environment such as high temperature and low temperature or ultraviolet radiation, it does not turn black and does not degenerate.

It has a strong absorption capacity for visible light with a wavelength below 450μm and can be stored in the fiber by irradiating for about 10 min in a light environment. It can continuously emit light and release various colors at night or in the dark. The afterglow is more than ten h, and it can be used infinitely.

The use of light-emitting fibers to make textiles has exactly the same performance properties as ordinary fibers during the day and does not make people feel any special. Its luminescent composition is different from radioactive zinc sulfide glow in the dark powder, does not contain phosphorus, lead, chromium, potassium, and other harmful heavy metal elements; it is also different from various reflective materials and does not need to be coated on the surface of textiles. The light-emitting material is dispersed in the fiber molecules to form a stable structure by finishing.

These luminous materials will not fall off after washing. Thus, the textile still maintains a certain luminosity. The other part of the luminous material that is not firmly bonded to the fiber is washed off after washing, which reduces the luminous brightness, indicating that the washing performance of the fabric needs to be further improved.

The light-emitting fiber has excellent environmental performance; not only the colors are colorful, but also the final product does not need to be dyed. Not only does the dye not affect the fiber’s glow in the dark properties, but it also avoids the serious environmental pollution caused by the wastewater produced in the production process.
