Abstract

The invention discloses a water and oil repellent microcapsule finishing agent and a preparation method thereof. The finishing agent takes the shape of a sphere or ellipsoid, the average particle sizeof the finishing agent is 10-25 [mu]m, and the mass ratio of a core material to a wall material is 1:(0.7-1.8); the core material consists of multi-fluothane silicon acrylate, butyl acrylate and methyl methacrylate; and the wall material consists of sericin and chitosan. The water and oil repellent microcapsule finishing agent disclosed by the invention has the advantages of being high in filmingproperty, high in adhesion property and high in thermal resistance, and a residual liquid generated in the finishing process of the finishing agent disclosed by the invention can be cooled and recycled at a normal temperature, so that environment pollution and raw material waste are avoided.

Description

technical field

[0001] The invention belongs to the technical field of textiles and relates to a finishing agent for functional fabrics, in particular to a water- and oil-repellent microcapsule finishing agent and a preparation method thereof. Background technique

[0002] Water and oil repellent finishing is a symbol of the continuous development of textile products towards high performance and multifunctionality. The fabrics after water and oil repellent finishing have the characteristics of low surface energy. The importance of this kind of fabrics in the fields of clothing, decoration and industry has been gradually recognized and valued by people. The additives that can impart water and oil repellency to fabrics are mainly fluorine-containing acrylate polymers, which have the characteristics of good film-forming properties, strong adhesion, and UV resistance, and have the advantages of abundant raw material sources and easy production. , but also has the disadvantage o...
