Luminous fiber is a new functional and environmentally friendly material made of rare earth luminescent materials. The fiber is based on spinning raw material, adopts long afterglow rare earth aluminate luminescent material, and is made into luminous fiber by special spinning. The luminous fiber absorbs visible light for 10 minutes, and can store the light energy in the fiber, which can continue to emit light for more than 10 hours in the dark state. When there is light, luminous fibers show various colors, such as red, yellow, green, blue, etc. In the dark, the luminous fiber emits various colors of light, such as red light, yellow light, blue light, green light, etc. The luminous fiber is colorful and does not need to be dyed. It is an environmentally friendly and efficient high-tech product.

Traditional l telas luminosas are made of materiales luminiscentes por el método de recubrimiento, que tienen una sensación de tela, resistencia al lavado y efecto luminoso deficientes, y causan una grave contaminación ambiental durante la producción y el uso. Por lo tanto, el desarrollo de fibras luminosas es una tarea importante en la industria textil.

The luminescent material of luminous fiber can be divided into two types: self-luminous type and light-storage type. The basic component of self-luminous material luminoso is radioactive material, which does not need to absorb energy from the outside, and can continue to emit light at night or during the day. However, the use is greatly restricted, and the disposal after disposal is also a big problem. Light-storing luminous materials do not contain radioactive substances, and there are no restrictions in this regard, but they can only emit light by absorbing external light energy, and they must store enough light energy to ensure that they can always emit light. Another defect of traditional light-storage luminous materials (such as zinc sulfide fluorescent materials) is that the brightness is not enough and the light-emitting time is too short. Therefore, the development of an efficient and pollution-free light-storing luminescent material has become an important research topic for many scientists for a long time.

In recent years, many countries in the world have begun to study luminous materials suitable for fibers. For example, in 2002, two companies in the United States developed luminous fibers, which used zinc sulfide materials and phosphorus as the base material, and added radioisotope Ju-147. . Japan's Toray Company then used rare earth europium and metal oxides to make luminous materials for fibers, but they were all in the laboratory stage.

La fibra luminosa desarrollada por el profesor Ge Mingqiao de la Facultad de Textiles y Ropa de la Universidad de Jiangnan compensa las deficiencias anteriores. Es una nueva tecnología y un nuevo material con derechos de propiedad intelectual independientes en mi país, que llena el vacío en la tecnología nacional. La fibra luminosa investigada y desarrollada por él no solo tiene un alto brillo, un tiempo prolongado y un espectro cromatográfico completo, sino que también tiene un buen rendimiento de procesamiento textil.
