Abstract

The invention discloses a preparation method of a polydopamine structural color film, and relates to the technical field of polydopamine structural color film. The dopamine is polymerized on the surface of the fabric by using fabric as a substrate and dopamine-trishydroxymethylaminomethane as a buffer reagent. Form a structural color; by injecting a certain concentration of P(GMA‑co‑PEGMA) solution as a binder, the fastness and surface smoothness of the polydopamine structural color film are improved; by controlling the reaction time and the immersion angle of the fabric, the structure is improved The color property of the color film is conducive to the promotion of structural color in the textile industry.

Description

technical field [0001] The invention relates to the technical field of polydopamine structural color film, in particular to a preparation method of polydopamine structural color film. Background technique [0002] Printing and dyeing is a key industry to improve the grade and added value of clothing and home textile products, and occupies an irreplaceable position in the textile industry chain. However, the impact of printing and dyeing wastewater on the environment limits the development of the textile industry. In response to the national energy conservation and emission reduction policy requirements, the printing and dyeing industry has been adopting some clean pretreatment, dyeing and printing machine recycling technologies in recent years. For example, biological enzyme pretreatment, small liquor ratio dyeing technology, digital inkjet printing technology, and condensed water and cooling water recovery technology, etc. The popularization and application of these clean ...
