Finishing of silk textile with fluorinated polyacrylate latex and the effect of silicone cross-linking bond in copolymer on hydrophobicity and lipophobicity
The lightly cross-linked fluorinated polyacrylate latex was synthesized by emulsion copolymerization, in which fluorine containing acrylate, butyl acrylate(BA) and organosiioxane containing bisacrylate were used as monomers.The fluorine containing co-polymeric emulsion was obtained with narrow particle size distribution and the average particle size to be about 130 nm.The emulsion with and without addition of cross-linking agent was applied on silk textile finishing.The result shows that, treating with the emulsion without cross-linking agent, the water-and oilrepellency of silk fabric reached level 3-4 and level 3, respectively, and the contact angle was up to 133.5°.After addition of cross-linking agent, the emulsion can afford the silk fabric with better water-and oil-repellency of level 4 and level 3-4, respectively.The improvement of water-and oilrepellency can probably be attributed to the lightly cross-linking structure of fluoropolymer, the latter resulted in more dense film on the surface of silk fabric after finishing.
