Abstract
A method for enhancing the soil- and/or stain-resistant characteristics of polyamide and wool fabrics is provided. A variety of combinations of sulfonated resin, sulfonated phenolic compounds, compounds of sulfonated phenolics and aldehydes, fluorochemicals, modified wax emulsions, acrylics and organic acids of low molecular weight provide enhanced soil release and anti-stain properties.
Claims14
The method of enhancing soil- and stain-resisting properties of polyamide and wool fabrics comprising applying to the fabric an aqueous solution containing the condensation product of formaldehyde with a compound selected from the group consisting of bis(hydroxyphenyl) sulfone, phenylsulfonic acid, dihydroxy diphenyl sulfone, and benzene sulfonic acid;
- and at least one material selected from the group consisting of a wax emulsion and a fluorochemical;
- and a polymer selected from the consisting of acrylic polymer and copolymer.
An aqueous solution for enhancing the soil- and stain-resistant properties of polyamide and wool fabrics comprising in admixture a condensation product of an aromatic sulfonic acid and formaldehyde together with wax emulsion, a nonionic water based fluorochemical, and an acrylic polymer, said admixture having a pH below 10.
