Stain-resistant compositions comprising sulfonated phenol-formaldehyde condensation products and polymers of maleic anhydride and one or more ethylenically unsaturated monomers, polyamide textile substrates treated with the same, and processes for their preparation. The stain-resistant compositions and substrates possess improved stain resistance but do not suffer from yellowing to the extent that previously known materials do.

Process for importing stain-resistance to textile substrates

A stable, acidic disinfectant all-purpose liquid cleaning composition, free of detergent builders and substantially free of organic solvents, comprising a mixture of acid stable water-soluble and water-dispersible nonionic surfactants, organic acid and a water soluble, acid stable disinfectant compound in an aqueous medium. The composition spreads quickly and provides good detergency with efficient penetration of soils while maintaining a high level of disinfectant activity. A soil releasing agent may also be included in the composition in order to provide easier cleaning of the treated surface during subsequent cleaning operations. The composition is particularly effective for cleaning soap scum and mineral deposits from hard surfaces such as grout, ceramic tile, stainless steel and glass.

Acidic disinfectant all-purpose liquid cleaning composition

Stain-resistant, polyamide textile substrates treated with compositions comprising hydrolyzed ethylenically unsaturated aromatic/maleic anhydride polymers and processes for their preparation. The treated substrates possess stain resistance that is as good as or better than do previously known stain-resist treated substrates but do not suffer from yellowing to the extent that previously known treated substrates do.

Stain-resistant aromatic/maleic anhydride polymers

Stain-resistant substrates comprising sulfonated phenol-formaldehyde condensation products and polymers of ethylenically unsaturated monomers, polyamide textile substrates treated wtih the same, and processes for their preparation. The stain-ressitant compositions and substrates possess improved stain resistance but do not suffer from yellowing to the extent that previously known materials do.
