Inhibitory fiber against virulence factors production and method for producing same

A method for producing an inhibitory fiber against virulence factors production comprising a fiber and an inhibitor of virulence factors production fixed to the fiber by chemical bonding, the method comprising:

• irradiating the fiber with an electron beam;
• and
• bringing into contact with the fiber at least one compound selected from the group consisting of a phosphate group-containing compound, a carboxylic acid group-containing compound, and a ketone group-containing compound to chemically bond the at least one compound to the fiber.

A method for producing an inhibitory fiber against virulence factors production comprising a cellulose fiber and an inhibitor of virulence factors production fixed to the cellulose fiber by chemical bonding, the method comprising:

• bringing an aqueous solution containing phosphoric acid and urea into contact with the cellulose fiber to chemically bond phosphoric ester to the cellulose fiber.

A method for inhibiting virulence factors production using an inhibitory fiber against virulence factors production,

• wherein the inhibitory fiber against virulence factors production comprises a fiber and an inhibitor of virulence factors production fixed to the fiber by chemical bonding, and
• the inhibitor of virulence factors production includes at least one compound selected from the group consisting of a phosphate group-containing compound, a carboxylic acid group-containing compound, and a ketone group-containing compound.

A fabric comprising an inhibitory fiber against virulence factors production,

• wherein the inhibitory fiber against virulence factors production comprises a fiber and an inhibitor of virulence factors production fixed to the fiber by chemical bonding, and
• the inhibitor of virulence factors production includes at least one compound selected from the group consisting of a phosphate group-containing compound, a carboxylic acid group-containing compound, and a ketone group-containing compound.
