Problems solved by technology

The preparation of colored light-storage luminescent base material here is to add inorganic pigments in the preparation process of luminescent base material, and its burning temperature is as high as 900~1000°C, which requires high heat resistance of inorganic transparent color materials, which limits the process to a certain extent. Selection range of pigments

Abstract

The invention relates to a method for regulating the luminescence characteristic of a rare earth noctilucent fiber, and belongs to the fields of textile technology and optical technology. During the manufacturing process of the rare earth noctilucent fiber, an inorganic compound pigment in a definite proportion is added, so that the luminescence characteristic of the rare earth noctilucent fiber is changed. Therefore, the fiber can present rich and colorful colors in the daytime and also can emit rich and colorful light at night. The pigment is added during the preparation process of a spinning solution or a spinning masterbatch, so that the requirement for the heat-resisting performance of the pigment is lower relatively. According to the invention, the luminescence characteristic of the rare earth noctilucent fiber is regulated by changing the adding category and the adding proportion of the pigment. The method also has the advantages of easiness in process control and easiness in regulation level control.

Description

technical field [0001] The invention relates to a method for adjusting the luminescence characteristics of rare earth luminous fibers, and belongs to the fields of textile technology and optical technology. Background technique [0002] Rare earth luminous fiber is a kind of functional fiber that glows at night made of rare earth luminescent materials. As long as the fiber absorbs visible light for 10 minutes, it can continue to glow for more than 10 hours in a dark environment. It is non-toxic, non-polluting, and environmentally friendly, and is widely used in construction and decoration, transportation, night operations and other fields. [0003] In order to achieve a specific color, the usual practice is to dye the fiber, which to a certain extent has caused pollution to the environment; or add a colored light-storage type luminous base material to achieve colored and colored light effects. The preparation of colored light-storage luminescent base material here is to add...
