Abstract:
A method for treating an article having a textile surface with a stainblocker composition, the textile surface being formed from at least two types of dyeable nylon yarns, wherein at least one type of nylon yarn is dyeable by an acid dyestuff and at least one other type of nylon yarn is dyeable by a cationic dyestuff,the method comprising the steps of: (a) coloring the textile surface of the article with at least an acid dyestuff and a cationic dyestuff; (b) applying a stainblocker composition to the textile surface of the article, the stainblocker composition having a temperature from twenty to ninety-five degrees Celsius (20 to 95Â° C.); (c) using infra-red energy to dry the article in a drying zone having a temperature in the range from seventy-five degrees Celsius to ninety-five degrees Celsius (75-95Â° C.) for a time sufficient to allow the stainblocker composition to react with the nylon yarn in the textile surface; and (d) rinsing the textile surface of the article with water, and thereafter drying the same, such that substantially the entire textile surface of the article is coated with a stainblocker composition whereby the textile surface has a stain resistance of 9 or higher on the AATCC Red 40 Stain Scale.
