Abstract
The present invention is to provide a fibrous material containing an antibacterial antifungal agent consisting of specific metal salt of organic compound effective for both antibacterial and antifungal functions and various articles containing the same fibrous material. The inclusion of the antibacterial antifungal agent consisting of specific metal salt of organic compound in fibrous materials allows production of fibrous materials having extremely high antibacterial antifungal activity. Various articles containing the fibrous materials have found to exhibit excellent antibacterial antifungal effects.
Claims22
A fibrous material containing an antibacterial antifungal agent comprising a metal salt of an organic compound wherein said metal salt is a complex of a silver salt, a copper salt and a zinc salt.
A fibrous material containing an antibacterial antifungal agent comprising a metal salt of an organic compound, wherein said fibrous material is ion-exchange fibers and said ion-exchange fibers are carboxymethyl-modified cellulose fibers by substitution on said cellulose with carboxymethyl group.
A fibrous material containing an antibacterial antifungal agent produced by:
- adding a metal salt to ion-exchange fibers selected from the group consisting of polystyrenes, polyacrylics, polyamides, polyesters, polyethylenes and cellulose, said ion-exchange fibers having an acid group selected from the group consisting of sulfonic acid group, phosphonic acid group and carboxylic acid group;
- and then
- adding an organic compound, wherein said metal salt is a complex of a silver slat, a copper salt and a zinc salt.
A fibrous material containing an antibacterial antifungal agent produced by:
- adding a metal salt to ion-exchange fibers selected from the group consisting of polystyrenes, polyacrylics, polyamides, polyesters, polyethylenes and cellulose, said ion-exchange fibers having an acid group selected from the group consisting of sulfonic acid group, phosphonic acid group and carboxylic acid group;
- and then
- adding an organic compound, wherein said ion-exchange fibers are carboxymethyl-modified fibers by substitution on said at least one polyacrylics, polyamides, polyesters, polyethylenes and cellulose, with carboxymethyl group.
A fibrous material containing an antibacterial antifungal agent produced by:
- adding a metal salt to ion-exchange fibers selected from the group consisting of polystyrenes, polyacrylics, polyamides, polyesters, polyethylenes and cellulose, said ion-exchange fibers having an acid group selected from the group consisting of sulfonic acid group, phosphonic acid group and carboxylic acid group;
- and then
- adding an organic compound, wherein said fibrous material is produced by adding at least one selected from the group consisting of silver salts, copper salts and zinc salts to a carboxymethyl modified cellulose being substituted with carboxymethyl group, followed by adding at least one selected from the group consisting of benzimidazole compounds, mercaptopyridine-N-oxide compounds, isothiazolone compounds, benzothiazole compounds and benzothiazolone compounds at a pH of 5 to 8.
