Abstract

The aqueous dispersions based on perfluorinated acrylate and other comonomers were prepared by means of emulsion polymerization in the presence of stearyl trimethyl ammonium chloride (STAC) and 2,2′-azobis(2-amidinopropane) dihydrochloride (ABAP) as water-soluble initiators. Several different types of resins and additives were added with the water-repellent polymers. Hydrostatic pressure and water repellency of fabrics that were treated by fluorinated water repellents with different recipes were measured and compared. In addition, the nano clay and the blocked isocyanate crosslinking agent (Jintexguard FCN) do, indeed, substantially increase the hydrostatic pressure. Actually, increased hydrostatic pressure for the water repellent treated fabrics is our objective of this study. However, our recipes containing the fluorinated-acrylate copolymer, nano clay, and Jintexguard FCN will successfully provide excellent hydrostatic pressure, excellent water repellency, and excellent soft hand. © 2006 Wiley Periodicals, Inc.
