Chinese patent CN 101275362A discloses a preparation method of fluorescent silk assembled with quantum dot nanoparticles, which uses silk as the substrate, connects a layer of organic polymer material on the surface of silk through electrostatic adsorption, and then absorbs the organic polymer material through the organic polymer material Quantum dot nanoparticles, and then adsorb organic polymers through quantum dot nanoparticles to obtain silk fibers coated with quantum dots one or more times. The fluorescent silk fibers prepared by this method have a low degree of binding between the fluorescent substance and the silk fibers, and It is easy to cause uneven fluorescence intensity and affect the use effect

Abstract

The invention provides a fluorescent silk fiber based on BODIPY dyes and a preparation method of the fluorescent silk fiber. The preparation method comprises the following steps: swollen silk fibers are immersed in a zeolite-containing aqueous solution and are pretreated, then are repeatedly immersed in hydrophilic BODIPY fluorescent dyes and a low molecular chitosan solution, and finally are steamed, heated and cured to obtain the fluorescent silk fiber. The fluorescent silk fiber based on BODIPY dyes prepared according to the method is stable in fluorescence, high in strength and uniform in color, can be produced in large scale, has excellent mechanical properties and high flexibility, and is applicable to the textile, bio-medical treatment, anti-counterfeiting and many other fields.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, and in particular relates to a fluorescent silk fiber based on BODIPY dyes and a preparation method thereof. Background technique: [0002] As we all know, the color of natural silk is white or yellow. With the continuous advancement of science and technology, people have expanded the color of silk to red, green, orange, etc. through functional modification. In addition, it can also have fluorescence, UV protection, and antibacterial. And other functions, not only expanded the application of silk in the textile field, but also began to involve biomedicine, anti-counterfeiting identification and other fields. [0003] At present, there are mainly three methods for fluorescent silk: transgenic engineering, silk post-processing and feeding method. Among them, transgenic engineering and feeding method have many uncontrollable factors, and the process is complicated, costly, and inefficient...
