Embodiment 1）

[0065] This example is an example in which a compound containing a phosphoric acid group (hereinafter also referred to as a phosphorus compound) is bonded to cellulose fibers of cloth by the Pad method. Among the above, they correspond to the cases represented by the formulas (1) to (5). Using an electron curtain (electrocurtain) type electron beam irradiation device (EC250 / 30 / 90L; manufactured by EYE ELECTRON BEAM Co., Ltd.), under the conditions of a nitrogen atmosphere, an accelerating voltage of 200kV, and an irradiation dose of 40kGy, the caustic soda mercerizing treatment was performed. 100% cotton fabric of medium thickness (weight per unit area 300g / m 2 ) is irradiated with an electron beam. The cloth irradiated with electron beams was dipped in 10% by mass of P1M {mono(2-methacryloyloxyethyl) phosphate; manufactured by Kyoeisha Chemical Co., Ltd.} aqueous solution, and squeezed to The liquid rate was about 70 mass %, and it left to stand overnight at 35 degreeC afte...

Embodiment 2）

[0069] This example is an example in which the Pad method of Example 1 is replaced by the dipping method. Nitrogen bubbling treatment was performed on the 10% by mass P1M aqueous solution in advance so that the dissolved oxygen concentration was 0.1 ppm or less. Using an electron curtain type electron beam irradiation device (EC250 / 30 / 90L; manufactured by EYE ELECTRON BEAM Co., Ltd.), under the conditions of a nitrogen atmosphere, an accelerating voltage of 200kV, and an irradiation dose of 40kGy, 100% cotton that has undergone caustic soda mercerizing treatment Medium-thick texture fabric of fiber (mass per unit area 300g / m 2 ) is irradiated with an electron beam. Immerse the cloth irradiated with electron beams in the above-prepared 10% by mass P1M aqueous solution with a dissolved oxygen concentration of 0.1ppm or less (bath ratio: about 1:15), seal it, and leave it at 50°C for 1 hour, then 35°C Leave it overnight. After washing with hot water and water to remove unreact...

Embodiment 3）

[0073] This example is an example in which acrylic acid is used as a compound containing a carboxylic acid group and bonded to cellulose fibers of cloth by the Pad method. This corresponds to the cases shown in the above formulas (6) to (10). Using an electron curtain type electron beam irradiation device (EC250 / 30 / 90L; manufactured by EYE ELECTRONBEAM Co., Ltd.), under the conditions of a nitrogen atmosphere, an accelerating voltage of 200kV, and an irradiation dose of 40kGy, 100% cotton fibers that have undergone caustic soda mercerizing treatment Medium-thick texture fabric (mass per unit area is 300g / m 2 ) is irradiated with an electron beam. The cloth irradiated with electron beams was dipped in a 10% by mass acrylic acid (manufactured by NACALAITESQUE Co., Ltd.) aqueous solution, squeezed with a squeezer until the squeeze rate was about 70% by mass, and then left at 35° C. overnight. After washing with hot water and water to remove unreacted monomers adsorbed on the cl...

Abstract

A pathogenic factor production-inhibiting fiber is obtained by fixing a pathogenic factor production-inhibiting component to fiber by chemical bonding, wherein the pathogenic factor production-inhibiting component includes at least one compound selected from the group consisting of a compound containing a phosphoric acid group, a compound containing a carboxylic acid group, or a ketone group-containing compound. A method of producing a pathogenic factor production-inhibiting fiber obtained by fixing a pathogenic production-inhibiting component to fiber by chemical bonding includes: a step for irradiating the fiber with electron beams; and a step for bringing into contact with the fiber at least one compound selected from the group consisting of a compound containing a phosphoric acid group, a compound containing a carboxylic acid group, or a ketone group-containing compound. Another method of producing a pathogenic factor production-inhibiting fiber obtained by fixing a pathogenic factor production-inhibiting component to fiber by chemical bonding, wherein a phosphate ester is chemically bonded to the fiber by bringing an aqueous solution containing phosphoric acid and urea into contact with the fiber.

Description

technical field [0001] The present invention relates to a pathogenic factor production inhibiting fiber obtained by immobilizing a pathogenic factor production inhibiting component on the fiber through a chemical bond, and a method for producing the same. Background technique [0002] Antibiotics such as antibiotics are used to treat infectious diseases, but due to the misuse of antibacterials, multidrug-resistant bacteria that are ineffective against antibiotics have emerged, causing nosocomial infections. The status quo is that there is no effective treatment for nosocomial infections, and large medical problems remain. Main pathogenic bacteria of the nosocomial infection include Pseudomonas aeruginosa and Staphylococcus aureus. Pseudomonas aeruginosa and Staphylococcus aureus are representative human opportunistic pathogens, and immunocompromised patients become infected, sometimes leading to the death of patients. Any kind of pathogenic bacteria has high resistance to ...
