Abstract
The neutralization of odors and removal of soil from fibrous surfaces, e.g., carpets, can be carried out using fabric treatment compositions containing certain combinations of metal salts and carriers.
Claims18
A dry composition useful for treating fibers comprising:
- (a) 0.01-2% salt of at least one divalent transition metal compound;
- (b) 0-10% of at least one conventional additive selected for the group consisting of agglomerating, fragrancing and processing agents;
- and
- (c) q.s. to 100% of at least one inorganic alkali or alkaline earth metal compoind as a carrier.
1 more element
A process for treating a fibrous surface comprising the steps of contacting that surface with a dry composition comprising:
- (a) 0.01-2% of a salt of at least one divalent metal compound containing zinc or a transition metal;
- (b) 0-10% of at least one conventional additive selected from the group consisting of agglomerating, fragrancing and processing agents;
- and
- (c) q.s to 100% of at least one inorganic alkali or alkaline earth metal compound as a carrier.
1 more element
A process for rendering fibrous surfaces odor resistant comprising the steps of:
- (1) depositing a salt of at last one divalent metal compound containing zine or a transition metal onto particles of a carrier, which carrier is at least one inorganic alkali or alkaline earth metal compound;
- (2) recovering the product of step (1);
- and
- (b 3) depositing a dry composition containing the product of step (2) upon a fibrous surface.
