| 摘 要： | IntroductionFluorinated coatings are the most i mportant class ofwater and oil repellent finishing agents for textiles due totheir opti mum perfor mance in lowering the surface freeenergy1]and i mproving both hydrophobicity andoleophobicity .

| Abstract: | As very useful superficial modification agents, the common long perfluoroalkyl - containing agents are facing the ecological problems, such as persistence, bioaccumulation,and/or toxicity in the environment. In order to overcome the problems, we designed and synthesized a polyether diol containing short perfluoroalkyl side chains, which was condensed with diisocyanate to form fluorine-containing aqueous polyurethane. This aqueous polyurethane was applied on cotton fabrics by conventional pad-dry-cure process. The treated cotton fabrics showed good water repellent property with the contact angle reached 131°, and also possessed good washing durability. |
