Abstract (en)
A method for treating fibrous textile substrate is presented comprising the steps of: a) applying, as a mist, onto the substrate, an aqueous liquid composition comprising from 0.2 to 2 % by weight of a fluorochemical substance or substances, wherein the number median diameter of the droplets in said spray is from 20 to 70 microns, and wherein said application is such that a uniform application of from 0.2 to 1.5 weight % of solids based on the weight of the substrate is deposited onto said substrate, and b) heating the resulting treated substrate at temperatures of from 85 DEG C to 116 DEG C sufficient to remove substantially all of the water from the applied aqueous liquid and to cure or coalesce the applied fluorochemical substance or substances.
