Surface Properties and Application of Fluorinated Emulsifier-free Emulsion Surface Sizing Agent
Fluorinated emulsifier-free emulsion surface sizing agent (FEE) was prepared by emulsifier-free polymerization of hexafluoro-butyl methacrylate (FA), styrene (St) and so on in the presence of fuorinated random amphiphilic polymers (ASRF) copolymerized by FA, St and acrylatic acid.Effects of ASRF content and treatment temperature on the surface properties of the films were investigated.Effects of ASRF content and oxide starch on the application were also discussed.Additionally, fiber morphologies of the samples were characterized by SEM.The results show that the appropriate increases of ASRF content and treatment temperature are good for the decreases of surface free energies of the films.When the ASRF content and oxide starch content is 5% and less 50% respectively, the FEE and its combination with oxide starch have good sizing performance.After the treatment by FEE, the fiber surface becomes smooth, which provides lower surface free energy of the fibers.
