Abstract
Using fluorinated acrylate (FDA) as functional monomer,the co-polymeric emulsion were prepared with acrylates(homemade) as soft monomers,sodium dodecyl sulfate (SDS) and Span-80 as emulsifie,ammonium persulfate as initiator,and methyl methacrylate(MMA) as stiff monomer.The obtained latex was characterized by FT-IR,and was used to treat cotton fabrics. Adopting two dipping and two padding finishing processes, then the treated fibrics were dried at 110°C for 1.5 min,finally cured at 170°C for 3min.The contact angles, water/oil repellency and mechanical properties of treated fabrics were tested. The results showed that the contact angle can approach to 134.3 °, water-repellency rate and oil-repellency rate of the treated fabrics can reach grade 3-4 and 1, respectively. There was little change in whiteness and wrinkle recovery angle.
