US Patent:

61655457, Dec 26, 2000

Filed:

Aug 12, 1999

Appl. No.:

9/372492

Inventors:

Richard J. Moody - Wilmington DE

International Classification:

B32B 3500
B05D 118
B05D 302

US Classification:

427140

Abstract:

A method is provided for after-treating fabric with a fluoroacrylate emulsion by immersion, typically under poorly-controlled conditions (e. g. field conditions), and a second embodiment of this method is provided for treating large, previously manufactured items comprising fabric (e. g. upholstered furniture, tents, awnings, and the like) with an aerosol spray containing micrometer or submicrometer-sized droplets of a diluted version of the fluoroacrylate emulsion. In both embodiments, the fluoroacrylate emulsion contains, dispersed therein with the aid of a surfactant system containing an amphoteric surfactant, essentially a single particulate fluoroacrylate copolymer having repeating units of the formulas I and II ##STR1## wherein R. sub. f is a fluorinated alkyl radical; R and R. sup. 1 are hydrogen or alkyl; and R. sup.

Abstract:

A method is provided for after-treating fabric with a fluoroacrylate emulsion by spraying or immersion. The immersion can be carried out in a laundering process (preferably in a late cycle of the process) or even under poorly-controlled conditions (e. g. field conditions). The spraying embodiment of this method is useful for treating large, previously manufactured items comprising fabric (e. g. upholstered furniture, tents, awnings, and the like) with an aerosol spray containing micrometer or submicrometer-sized droplets of a diluted version of the fluoroacrylate emulsion. In all embodiments, the fluoroacrylate emulsion contains, dispersed therein with the aid of a surfactant system, essentially a single hydrophobic component comprising a particulate fluoroacrylate copolymer having repeating units of the formulas I and II ##STR1## wherein R. sub. f is a C. sub. 8 -rich fluorinated alkyl radical; R and R. sup. 1 are hydrogen or alkyl; and R. sup.

Abstract:

An image-printing process comprising applying to a substrate a printing ink containing from about 0. 01% to 1. 0%, based on the total weight of the ink, of a fluorocarbon surfactant containing a fluorocarbon moiety selected from the group. Cf. sub. 3 (cf. sub. 2). sub. 3 cf. sub. 3 cf(cf. sub. 3)o-, and CF. sub. 3 CF(CF. sub. 3)CF. sub. 2 -, the surfactant containing at least 25% fluorine by weight; also, printing inks containing particular surfactants having the CF. sub. 3 (CF. sub. 2). sub. 3 moiety.
