Abstract

The invention relates to a method for modifying physical color fibers based on flake silver nanoparticles. The method includes the following steps: using the silver nanosheet / TPU spinning solution as the internal phase solution, using the coagulation bath solution as the external phase solution, the coagulation bath solution is used to solidify the silver nanosheet / TPU spinning solution, and adopting a microfluidic chip device for microfluidic Spinning is controlled so that the internal phase solution is injected into the external phase solution and formed under the action of the external phase solution. The formed fiber flows out from the outlet of the microfluidic chip device, and the outflowing fiber is washed and solidified completely to obtain a sheet-like silver nanoparticle-based The physical color fiber; then the cured physical color fiber based on flake silver nanoparticles is dried, and then treated at 115-165°C for 5-10min to obtain the modified physical color fiber. The invention adopts an annealing method to improve the color strength, stability, oxidation resistance and mechanical properties of the physical color fiber based on the flake silver nano particles.

Description

technical field [0001] The invention relates to the technical field of fiber preparation, in particular to a method for modifying physical color fibers based on flake silver nanoparticles. Background technique [0002] Physical color is a color produced by physical interactions such as optical processes such as diffraction, scattering, and interference between visible light and micro-nano photonic structures, or the physical characteristics of the object itself. Chemical coloring mainly relies on the action of light and the chromogenic groups of chemical dyes to produce color. Since chemical dyes are mainly aniline series aromatic hydrocarbon compounds, there are many problems in recycling, and improper disposal will easily cause great pollution to the environment. Therefore, physical color, as a new coloring method with no pollution and low energy consumption, is conducive to reducing the pressure of environmental governance and has great application prospects.
