Abstract
A liquid or dry, flowable cleaning composition for carpeting is provided which comprises: (1) a cleaning fluid selected from water containing sufficient surfactant to lower the surface tension to below 40 dynes per centimeter, an organic liquid, or mixtures of water, surfactant and organic liquid; and (2) a sulfonated, colorless dye site blocker provided in a sufficient amount to prevent or minimize deterioration of stain resistance properties in fifth generation nylon carpets. In the case of a dry-type composition sufficient particulate material is added to provide a dry, flowable product.
Claims15
A cleaning composition for carpeting which comprises:
- (1.) a cleaning fluid selected from water containing sufficient surfactant to lower the surface tension to below 40 dynes per centimeter, an organic liquid selected from C.sub.1 to C.sub.4 aliphatic alcohols, high boiling hydrocarbon solvents and high boiling chlorinated hydrocarbon solvents, or mixtures of water, surfactant and said organic liquid;
- and (2.) a sulfonated, colorless dye site blocker provided in a sufficient amount to prevent or minimize deterioration of stain resistance properties in fifth generation nylon carpets;
- and wherein furthermore said dye site blocker is selected from aliphatic sulfonated polyesters;
- lignin sulfonates;
- sulfonated phenol-formaldehyde condensation products;
- condensation products prepared from mono-sulfonic acids having repeating units of the formula:
- ##STR4## wherein the product ratio of (A) to (B) is 60 to 40 in the product having repeating units of the formulas:
- ##STR5## where the ratio of units (C) to (D) is at least 8 to 1 sulfonated phenolformaldehyde condensation products in which from about 10 to 25 percent of the polymer units contain SO.sub.3 radicals and about 90 to 75 percent of the polymer units contain sulfone radicals and in which a portion of the free hydroxyl groups thereof have been acylated or etherified.
A powdered cleaning composition for carpeting which comprises:
- (1) a cleaning fluid selected from water containing sufficient surfactant to lower the surface tension to below 40 dynes per centimeter, an organic liquid selected from C.sub.1 to C.sub.4 aliphatic alcohols, high boiling hydrocarbon solvents and high boiling chlorinated hydrocarbon solvents;
- or mixtures of water, surfactant and said organic liquid;
- (2) a particulate material in an amount of at least about 30 percent by weight based upon the weight of said composition;
- and (3) a sulfonated, colorless dye site blocker provided in a sufficient amount to prevent or minimize deterioration of stain resistance properties in fifth generation nylon carpets and wherein furthermore said dye site blocker is selected from aliphatic sulfonated polyesters;
- lignin sulfonates;
- sulfonated phenol-formaldehyde condensation products;
- condensation products prepared from mono-sulfonic acids having repeating units of the formulas:
- ##STR7## wherein the product ration of (A) to (B) is 60 to 40 in the product having repeating units of the formulas:
- ##STR8## where the ratio of units (C) to (D) is at least 8 to 1;
- sulfonated phenol-formaldehyde condensation products in which from about 10 to 25 percent of the polymer units contain SO.sub.3 radicals and about 90 to 75 percent of the polymer units contain sulfone radicals and in which a portion of the free hydroxyl groups thereof have been acylated or etherified.
