Abstract
Textiles coated with aqueous compositions of silane quaternary ammonium compounds and alkali metal bicarbonates are provided with deodorization properties and protection from allergens, irritants, molds, dust mites, bacteria, and fungi.
Claims26
An article comprising a textile coated with an aqueous composition comprising an alkali metal bicarbonate and a silane quaternary ammonium compound present in amounts of from about 0.3 to 5.0 percent by weight relative to the weight of the aqueous composition.
An article comprising a textile coated with a composition comprising a silane quaternary ammonium compound present in amounts of from about 0.3 to 5.0 percent by weight relative to the weight of the aqueous composition, an alkali metal bicarbonate and a nonionic surfactant, wherein the weight ratio of said silane quaternary ammonium compound to said nonionic surfactant ranges from about 10:1 to 1:<3.0.
An article comprising a textile coated with an aqueous composition prepared by the method comprising:
- a) admixing an effective amount of an alkali metal bicarbonate and a silane quaternary ammonium compound in the presence of water such that the silane quaternary ammonium compound is present at a concentration of from about 0.3 to 5.0 percent by weight relative to the weight of the aqueous composition;
- b) applying the aqueous composition to the textile;
- and
- c) allowing the aqueous composition to dry so that the silane quaternary ammonium compound binds to the surface of the textile.
