Abstract
In recent years, remarkable development and progresses have been made on the study of oleophobic modification
of fibers. Modified oleophobic fibers have broad application prospects not only owing to their important uses in daily life, but
also their extraordinary use in the fields of defense science and technology, and medical health care. In this study, fluorinecontaining
acrylate (FP) emulsion was synthesized via emulsion polymerization method using perfluorooctyl acrylate
(PFOA) as the fluorine-containing monomer, and butyl acrylate (BA) and styrene (St) as the basic monomers. In addition,
SiO2 hydrosol was also prepared by water-based sol-gel reaction using tetraethyl orthosilicate (TEOS) as the precursor.
Fourier transform infrared spectroscopy, scanning electron microscopy, atomic force microscopy, particle size analysis,
thermogravimetric analysis and contact angle measurement were used to characterize the structural morphology and thermal
stability of the FP polymer. The as-obtained FP and SiO2/FP were coated on cotton fabrics by the impregnation-curing
method, successfully affording the cotton fabrics with oleophobic property. The application performance of the fabrics before
and after finishing were measured and analyzed, and the effect of rubbing and soap washing on the oleophobic property of the
fabrics were investigated. Then property changes, such as the anti-ultraviolet property, whiteness, breathability, and breaking
strength, of the fabrics before and after finishing were investigated. The results showed that the FP finishing agent exhibited
excellent thermal property and satisfied the basic requirements for the fabrics finishing agents. The oleophobic property of
the fabrics after FP emulsion finishing achieved grade 5, with no wettability to n-dodecane. The oleophobic property of the
SiO2/FP treated fabrics was better than those of the FP treated fabrics, indicating that the roughen treatment of cotton fabrics
surfaces using silica sol first and then coating with FP improved the oleophobic property. The combined actions of the coarse
surface structure provided by SiO2 nanoparticles and the low surface energy of the fluorine-containing polymers afforded the
cotton fabric surfaces with oleophobic property. The treated fabrics retained good oleophobic performance after multiple
times of water washing and rubbings, and the physical mechanical properties of the cotton fabrics did not change much
before and after finishing, and thus did not affect the clothing performance of the cotton fabrics.
