Abstract:

In order to explore the application effects of fluoropolymer on linen fabric, a fluorine-containing acrylate copolymer emulsion was prepared by semi-continuous seeded emulsion copolymerization using dodecafluloroheptry methacrylate (G04) as modified monomer, butylacrylate (BA) and methylacrylate (MMA) as soft and bard monomer, respectively, and acrylic acid sa functional monomer; ana it was applied to finishing linen fabric. Structure and properties of the product were characterized and analyzed by FTIR, TEM, PSD and CA tester, respectively. Water and air permeability and breaking strength of the treated fabric were investigated. The result showed that the obtained fluorine-containing acrylate copolymer emulsion had a core-shell structure, and the microsphere size was at nanometer. After the linen fabric was treated with fluorine-containing copolymer, the contact angle to water was up to 130°, and the breaking strength of fabric was increased. The water and air permeability of  fabric decreased slightly.
