Synthesis and characterization of fluoride polyacrylate emulsion for super-hydrophobic and oleophobic fabric finishing

The fluoride polyacrylat emulsion was synthetized by no soap emulsion polymerization and used as water proofing and oil proofing finishing agent.FTIR,SEM and TEM were adopted to analyze the structure and morphology of emulsion and finished fabric.The influence of fluoride monomer and cross-link ing monomer dosage on the emulsion properties were discussed.The water and oil repellent ability,as well as whiteness,crease recovery angle,gas permeability and tensile strength of the fabric before and after finish ing were also investigated.The results showed that the water and oil repellent ability enhanced with the in crease of fluorine monomer dosage,and the increase of cross-linking monomer could help to improve the washing resistance of the fabric.When the contents of fluorine monomer and cross-linking monomer were 10% and 0.6%,respectively,the water repellency of finished fabric was 100 points,the H2O contact angle could reach 160° and the properties of oil repellent could reach level 7.After washed for 10 times,the fabric still maintained relatively high water and oil repellent.The finished fabric basically maintained the original prop erties,only the whiteness and gas permeability of cotton fabric slightly declined,while recovery angle and breaking strength increased.
