Problems solved by technology

However, some studies have found that perfluorinated water and oil repellents containing 8 carbons or more contain a small amount of PFOA as an impurity, and PFOA has low natural degradation ability in the environment, high bioaccumulation, and long-distance migration. Has now been banned by the EU resolution

Abstract

The invention relates to a fabric finishing agent and a preparation method thereof, and belongs to the technical field of printing and dyeing auxiliary agents. The fabric finishing agent contains a polyether chain segment, an epoxy group and a fluorine-containing chain segment at the same time, and the one end of the fluorine-containing chain segment contains an alkene. the characteristics of being safe in raw materials, simple in technology and the like are provided when the fabric finishing agent is applied to printing and dyeing and the preparation method is applied to prepare the fabric finishing agent, the fabric finishing agent is capable of keeping original clothes performances and hand feeling of fabrics, and also is capable of effectively improving the water-repellent oil-repellent properties of fabrics.

Description

technical field [0001] The invention relates to a fabric finishing agent and a preparation method thereof, belonging to the technical field of printing and dyeing auxiliaries. Background technique [0002] Polysiloxane is a kind of semi-organic and semi-inorganic polymer compound with a special siloxane backbone structure. It has excellent heat resistance, weather resistance, unique low glass transition temperature, low surface tension and other characteristics. Fluorine-containing silicone polymers not only have the characteristics of silicone polymers, but also have excellent oil resistance and solvent resistance due to the introduction of fluorine-containing groups, that is, they combine the high surface activity of fluorine, high heat resistance stability, high Chemically inert, hydrophobic and oil-repellent "three highs and two phobias" characteristics. That is to say, the fluorine-containing silicone finishing agent has the superior properties of polysiloxane and fluo...
