Abstract

The invention discloses a three-proofing finishing agent for textile, as well as a preparation method and application thereof, and belongs to the technical field of textile finishing agents. The preparation method comprises the following steps: (1) adding a comonomer mixture, silicon dioxide hydrosol and an emulsifier into a solvent, and emulsifying to obtain pre-emulsion; (2) adding an initiator into the pre-emulsion, and polymerizing to prepare the three-proofing finishing agent for textile. According to the preparation method, the silicon dioxide hydrosol is introduced into fluoro-containing polymer with low surface energy and water and oil repelling performance, a nanoscale multi-dimensional rough structure is given to the surface of finished textile, super-hydrophobic / super oleophobic performance is shown, and the finishing agent has a better three-proofing effect; and a dopamine group with strong adhesion and self-crosslinking characteristics is introduced, so that the adhesion performance and crosslinking firmness of the three-proofing finishing agent can be remarkably enhanced, adhesion between the three-proofing finishing agent and a treated base material can be promoted, and the durability and washing resistance of the three-proofing effect of the finished textile can be improved.

Description

technical field [0001] The invention relates to the technical field of fabric finishing agents, in particular to a fabric three-proof finishing agent and its preparation method and application. Background technique [0002] Fabric three-proof finishing agent, "three-proof" refers to water-repellent, oil-repellent, and stain-repellent finishing. It is to apply one or several finishing agents on the fabric to change the surface properties of the fabric, so that the fabric is not easily wetted by water and common oil stains. wet or dirty. At present, the three-proof finishing effect mainly utilizes the surface energy characteristics of perfluoroalkyl acrylate copolymers. Perfluoroalkyl copolymer systems include solution type and emulsion type. In recent years, considering safety and environmental issues, this type of perfluoroalkyl Alkyl copolymer oil and water repellent finishing agents are mostly water-dispersed emulsion type. [0003] At present, the fluorine-containing mo...
