Enhancement of the water repellency durability of the fabrics treated by fluorinated nanocopolymer emulsions

Abstract

ABSTRACT:The fluorinated copolymer emulsions containing different monomers with the reactive groups were successfully prepared at our lab, using emulsion polymerization technique. The water repellency and the durability for the fabrics treated by fluorinated water repellents after 30 and 50 washes were measured and compared. Actually, the combination of the comonomers containing blocked isocyanate or other reactive groups after copolymerization would increase the durability of the water repellency. In addition, the blocked isocyanate crosslinking agent (Jintexguard FCN) does, indeed, substantially increase the durability also. It clearly indicates that the copolymer emulsion prepared by the reaction of fluorinated acrylate, cyclohexyl methacrylate, and 3-chloro-2-hydroxy-propyl methacrylate(Topolene M) with monomers containing blocked isocyanate group(Jintexan BIA) showed very good durability. More importantly, the combination of this copolymer and Jintexguard FCN will significantly provide excellent water repellency and durability after 50 washes.

Preparation and characterization of a novel fluorinated acrylate resin

“…Among the fluoropolymers, the popularity of fluorinated acrylic polymers is increasing as components for high-performance paint and varnish in the textile, paper, leather, construction, automotive and aerospace industries, optics and microelectronics. There are a number of papers concerning their preparation and properties, most of which fluorinated acrylic emulsions have been prepared via different emulsion polymerization technologies [8][9][10][11][12][13][14][15][16][17][18]. However, the constituent of the fluorinated acrylate latex, which is prepared via emulsion polymerization, is complex.…”

Preparation and characterization of novel self cross‐linking fluorinated acrylic latex

“…It possesses the hydrophobic, oleophobic, and antifouling surface behavior. It has been widely used in the field of coatings, fabric finish, leather, and packing 1–4…”

“…Presently, acrylic monomers and fluorine monomers are extensively used to produce latex; and usually two or more monomers are copolymerized via a seeded semibatch approach to provide lattices with desirable properties 5–15. However, the preparation of the self crosslinking fluorinated acrylic latices (SCLFAL) is seldom reported.…”

Recent advances in the modification of polyacrylate latexes

“…However, the storage stability of the latex prepared by blend method is bad and the content of fluorine is not high. To improve the stability of the latex, many fluorinated (meth)acrylate monomers have been applied to synthesis fluorinated polyacrylate with conventional (meth)acrylate monomers in aqueous emulsions by radical polymerization methods [45][46][47][48]. Ma et al [49] developed a semi-continuous emulsion polymerization method to prepare fluorinated polyacrylate latex using SDS and poly(ethylene glycol) as emulsifier which is a random copolymer of hexafluorobutyl acrylate, butyl acrylate, and methyl methacrylate.…”
