Abstract
The invention discloses a preparation method of a rare-earth luminescent fiber. The preparation method of the rare-earth luminescent fiber comprises the following steps: preparing luminescent powder; drying a polyester chip; and blending and spinning. According to the preparation method disclosed by the invention, the luminescence characteristic of the fiber can be improved; and the perdurability and the uniqueness are ensured.
Description
Technical field
The present invention relates to a kind of preparation method of fiber, be specifically related to a kind of preparation method of rare earth luminescent fiber.
Background technology
Luminescent fibre generally refers in the dark can the high-tech functional fibre of automatic luminous.Early stage self-luminescent material, is called first generation luminescent material, can trace back to Madame Curie and find radium element, have certain radioactivity; Second generation self-luminescent material, namely traditional sulfide luminescent material, owing to having certain toxic, radioactivity to human body, and the shortcoming such as luminosity low and duration is short, its Application Areas is very restricted; Third generation light-storing and emitting material comes out the nineties in 20th century in China, is invented by the Novel self-luminescence material of rare earth as carrier.Compared with front two generation self-luminescent materials, this material non-toxic, the remarkable advantage such as "dead", fluorescent lifetime is grown, can be used repeatedly.Luminescent fibre can be widely used in the fields such as Aero-Space, night work, fire-fighting emergent, building decoration, communications and transportation, daily life and amusement.
From long-term perspective, continue the performance improving luminescent fibre, research applicability is stronger, and the better luminescent fibre of performance makes the important goal of our long-sought.Under the prerequisite not affecting fibrous mechanical property, how to improve rare earth luminous stability, luminous fidelity factor, extend fluorescent lifetime, reduce production cost, expansive approach field etc., are all worth continuing to show great attention to.In addition, due to production cost general higher of high-performance luminescent fibre, performance product better, cost is higher, and therefore purposes has just been restricted.
Therefore, the development trend of rare earth luminescent fiber will be the performance improving rare earth fiber, reduces production cost, expands purposes, and the luminescence mechanism of further investigation rare earth luminescent fiber, continually develops new product.
