Traditional Fibers Have Drawbacks. Luminous Fibers Secretly Attack Cities.

< p > radium elements and traditional sulfide fluorescent materials have certain disadvantages such as toxicity, radioactivity, low luminance and short duration. Therefore, their application fields are limited, so the rare earth luminescent fibers emerge as the times require.

Less than p days ago, the key technology and industrialization of high energy storage multicolor rare earth luminous fiber was completed by the Jiangnan University and Jiangsu Guo Da line Co., Ltd., which won the two prize of science and technology in 2013, < a href= "http://www.91se91.com/news/index_c.asp" > textile light < /a >.

< /p >

< p > The aim of this project is to systematically study the visible light absorption efficiency, energy pfer, storage efficiency and luminescence properties of luminescent materials for central rare earth ions and coordination. On the basis of this, a new rare earth luminous material suitable for fiber is successfully developed by combining sol-gel and high-temperature solid-phase sintering.

< p > making luminous fibers, < a href= "http://www.91se91.com/news/index_c.asp > > luminescent material < /a > divided into two types: self luminous and light storing. The basic components of self luminous luminous materials are radioactive materials, which do not need to absorb energy from the outside, and can continuously shine at night or during the day.

However, because it contains radioactive substances, it is subject to greater restrictions when used, and disposal after abandonment is also a major problem.

Light storing noctilucent materials do not contain radioactive substances and have no limitations in use. But they rely on absorbing external light energy to light up, and reserve enough light energy to ensure that they are always luminous.

< p > "the traditional luminous fabric is made by coating the luminescent material through the coating. The fabric has poor handle, wearability, washing resistance and poor luminous effect, and the pollution to the environment is serious during the production and use.

Another defect of the traditional light storing luminous material is that the luminance is not enough and the luminescence time is short.

Later researchers doped a radioactive isotope 147 in zinc sulphide fluorescent material. Its luminous effect is ideal, but the intervention of radioactive elements does not meet the requirements of environmental protection.

Therefore, it is imperative to develop an efficient and pollution-free light storing luminescent material.

Ge Mingqiao, director of the functional fiber research office of Jiangnan University, said.

< p > < strong > high efficiency and environmental protection as the highlight < /strong > < /p >

< p > "simply speaking, the high-efficiency storage type multicolor rare earth luminous material is a functional material that can leave the light source continuously and irradiate continuously after ultraviolet light or visible light source for a short time."

Ge Mingqiao said.

< /p >

< p > it is understood that the high-efficiency energy storage polychromatic rare earth < a href= "http://www.91se91.com/news/index_c.asp" > luminous fiber < /a > is based on polymer materials such as polyethylene terephthalate two, and functional assistants are used to pplant the luminous material with rare earth elements into the matrix and react to form a luminous type of spinning substrate.

By absorbing the visible light for 1 minutes, the noctilucent fiber can be stored in the fiber and can last 10 hours in a dark state, and it can be recycled.

At the same time, the project studied the manufacturing principle and processing method of polychromatic noctilucent polymer polymer spinning, designed and pformed the spinning equipment, optimized the spinning process, and successfully developed many kinds of rare earth luminous fibers with different varieties and colors.

It not only has brilliant and lasting color light, but also does not need to dye the final product, so as to avoid a lot of water and environmental pollution caused by dyeing and finishing process.

< /p >

< p > high energy storage polychromatic rare earth luminous fiber is a new technology and material with independent intellectual property rights in China, which fills the gap in China.

Noctilucent fiber not only has high brightness, long time, chromatographic spectrum, but also has good textile processing properties.

The main technical advantages are as follows: 1. the principle of storing light and emitting light of polychromatic rare earth luminous fiber; 2., the key technology of preparing rare earth luminous materials, focusing on the influence of luminous material content, particle size and boric acid content on the afterglow characteristics of luminous materials, and summarizing the optimal technological parameters; 3., the key technology of the high-efficiency energy storage type polychrome rare earth luminous fiber industrialization preparation; and solving the problem of poor touch, low intensity and more wool in the production and processing of the luminous fiber; 4., the development technology of the noctilucent fiber product, and developing a series of products to enter the market.
