Problems solved by technology

The dyeing of fluorescent dyes to prepare dyed fibers is traditionally simple and easy to implement, but the fiber dyeing process is time-consuming and laborious, and the dyeing bath will cause serious environmental pollution, and there are also problems such as poor color fastness of colorants and uneven luminescence.
Dye-grafted polymer monomers do not require dyeing process after spinning, but the chemical modification process is not easy to control and relatively cumbersome
Polymer fibers doped with rare earth substances or quantum dots have excellent fluorescent properties, but most of the preparation methods are cumbersome and complicated, and require relatively high equipment requirements. The chemical fiber substrate is still an environmentally incompatible material, which is difficult to degrade

Description

[Technical field] [0001] The present invention relates to the field of fiber material, and more particularly to the preparation method and application of nanofluorescence fibers. 【Background technique】 [0002] Fluorescence fibers have received attention due to its functionality of specific color light under specific light irradiation. Fluorescence fibers refer to fibers that bind fluorescent substances to become fibrous polymer blended spinning or by chemical methods to bind fluorescent substances to high polymers chains. Fluorescent substances generally select rare earth, organic small molecule, organic polymer fluorescent substance, quantum dot or nanoclusters. The application of fluorescent fibers mainly includes sensors, color display, luminescent materials, anti-counterfeiting materials and other fields. [0003] At present, the preparation method of fluorescent fibers can be roughly divided into two categories: one is to add fluorescent substances into a fibrous polymer ma...
