AI Technical Summary

Problems solved by technology

However, traditional denim fabrics have single functions, low grades, poor comfort, and low added value, which cannot meet people's needs for denim clothing. Therefore, the development prospects of denim fabrics with waterproof, oil-proof, and anti-fouling properties are very broad.

Abstract

The invention relates to the preparation of a core-shell structure fluorine-containing acrylate copolymer fabric finishing agent and its application method on denim clothing. It includes the preparation of a core-shell structure fluorine-containing acrylate copolymer emulsion, the preparation of a waterproof and oil-repellent fluorine-containing finishing agent for denim clothing and its waterproof and oil-repellent finishing for denim clothing. The solubilizer reacts with β-cyclodextrin (β-CD), adopts pre-emulsification semi-continuous seed emulsion polymerization method, uses water-soluble peroxide as initiator, anionic surfactant as emulsifier, fluorine-containing acrylate Monomers and acrylate monomers are used as raw materials to prepare a core-shell structure fluorine-containing acrylate copolymer emulsion, and to prepare a waterproof and oil-repellent finishing agent for denim clothing. The proportion of each component by mass is: fluorine-containing Emulsion 20%-40%, water-soluble silicone 10%-20%, softener 5%-10%, polyethylene glycol modified nano-titanium dioxide 0.3%-2%, penetrant JFC1%-5%, emulsion stability 1%-3% agent, 30%-50% water, the finished denim garments show good waterproof and oil-proof performance, and have lower cost than similar products.

Description

technical field [0001] The invention relates to the preparation and application of a water- and oil-repellent fabric finishing agent, in particular to the preparation of a core-shell structure fluorine-containing acrylate copolymer fabric finishing agent and its application method on denim clothing, which belongs to textile auxiliary agents and the field of textile fabric manufacturing technology. Background technique [0002] Due to the unique properties of fluorine atoms, fluoropolymers have low surface energy, which endows them with excellent water and oil repellency. Water and oil repellent finishing agents for fabrics usually refer to fluorine-containing finishing agents, and there have been a large number of relevant literature and patent reports on the preparation of fluorine-containing finishing agents. At present, the main manufacturers of fluorine-containing finishing agents include DuPont of the United States, 3M Company, Hoechst of Germany, Atochem of France, Da...
