Problems solved by technology

[0003] Although these fibers have the above-mentioned respective characteristics, there are certain application limitations in use. For example, in the textile field, the fabric is too thin, and its light-shielding performance is not good. If the fabric is too thick, because of its light-shielding performance. Affecting light, especially absorbing too much light, causing the fabric to heat up and affecting the use, if it is applied to the field of curtains, especially the morning and evening of the time cannot be judged through the curtains, and the shading performance is determined by the thickness and color of the curtain fabric. Realized, the use of such fabrics affects the overall layout of the interior and has a certain sense of depression, which is difficult to apply to families
[0004] Fibers applied to the field of environmental protection, because they cannot respond well to light, lead to low environmental performance

preparation example Construction

[0029] The preparation method of described polymethyl methacrylate modified photochromic agent, comprises the following steps:

[0030] 1) Adding methyl methacrylate monomer and ethanol into the reactor, after stirring, the methyl methacrylate is completely dissolved in ethanol, adding an inorganic discoloration agent, continuing to stir and raising the temperature to 60°C-80°C, Then add the initiator BPO ethanol solution, stop heating and keep stirring for 1-2 hours, and gradually cool into a solid;

[0031] 2) Grinding the above solid into powder to obtain a polymethyl methacrylate modified photochromic agent.

[0032] Polymethyl methacrylate modified photochromic agent is a shell-core structure with a photochromic agent as the core and a polymethyl methacrylate shell. The shell-core structure can ensure stability with polymer fibers. Combine and distribute evenly.

Abstract

The invention relates to color-changing fiber, which at least comprises photochromic fiber. According to the technical scheme, by adding a polymethyl methacrylate modified photochromic agent to polymer fiber and through coating of polymethyl methacrylate, uniform distribution of the photochromic material in the polymer fiber is realized; and the photochromic agent is an inorganic reversible photochromic agent, which realizes good ultraviolet light discoloration performance and improves ultraviolet light protective performance of the fiber. If the fiber is applied to textile fabric, the fiber can have a better ultraviolet light protective function; if the fiber is applied to the environmental protection field, the fiber also has better protection against damage caused by ultraviolet light.

Description

technical field [0001] The invention belongs to the technical field of macromolecular materials, and in particular refers to a color-changing fiber with ultraviolet protection and a corresponding change in the color of the fiber through the change of light. Background technique [0002] In the prior art, there are many types of fibers, and the uses of fibers are also very wide, including textile fields, optical fiber fields, environmental protection fields, and biological fields. [0003] Although these fibers have the above-mentioned respective characteristics, there are certain application limitations in use. For example, in the textile field, the fabric is too thin, and its light-shielding performance is not good. Affecting light, especially absorbing too much light, causing the fabric to heat up and affecting the use, if it is applied to the field of curtains, especially the morning and evening of the time cannot be judged through the curtains, and the shading performanc...
