Claims51
A fluorochemical mixture comprising:
- a. a composition comprising (1) at least one copolymer comprising at least one fluoroaliphatic radical-containing monomer and at least one non-fluorinated acrylate monomer and (2) at least one fluoraliphatic radical-containing ester;
- and
- b. a hydrocarbon solvent system which is essentially non-halogenated and substantially free of ketones and esters wherein said composition is soluble in said solvent.
A method of treating a textile comprising the steps of:
- a. contacting said textile with a fluorochemical mixture comprising:
- 1. a composition comprising (1) at least one copolymer comprising at least one fluoroaliphatic radical-containing monomer and at least non-fluorinated one acrylate monomer and (2) at least one fluoroaliphatic radical-containing ester;
- and
- 2. a hydrocarbon solvent system which is essentially non-halogenated and substantially free of ketones and esters wherein said composition is soluble in said solvent;
- and
- b. drying said contacted textile.
A textile treated with a fluorochemical mixture comprising:
- a. a composition comprising (1) at least one copolymer comprising at least one fluoroaliphatic radical-containing monomer and at least one non-fluorinated acrylate monomer and (2) at least one fluoraliphatic radical-containing ester;
- and
- b. a hydrocarbon solvent system which is essentially non-halogenated and substantially free of ketones and esters wherein said composition is soluble in said solvent.
