The inhibitory fiber against virulence factors production of the present invention is 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 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. The production method of the present invention is 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 comprises: 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. Another production method of the present invention is 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 fiber by chemical bonding. The method comprises: bringing an aqueous solution containing phosphoric acid and urea into contact with the cellulose fiber to chemically bond phosphoric ester to the cellulose fiber.

摘要:
A flame-retardant fabric may include a cellulosic fiber and a modacrylic fiber, the cellulosic fiber being a natural cellulose fiber containing a phosphorus compound, the modacrylic fiber containing an antimony compound, the flame-retardant fabric including the modacrylic fiber containing the antimony compound in an amount of 14 to 54 wt%, antimony in an amount of not less than 1.7 wt%, and phosphorus in an amount of 0.3 to 1.5 wt% with respect to the total weight of the flame-retardant fabric, and the flame-retardant fabric having a weight per unit area of not less than 160 g/m 2 . The flame-retardant fabric can be produced by subjecting a fabric including a natural cellulose fiber and a modacrylic fiber containing an antimony compound to flame-retardant treatment with a phosphorus compound.
摘要:
The invention discloses a method for preparing a salt-resistant and detergent-resistant alginate fiber, the fiber being a salt-resistant and detergent-resistant alginate fiber prepared by incorporating a borate-containing adjuvant, contacting and infiltrating a finished alginate fiber with the adjuvant solution and using selected proper raw materials in selected proportions and reaction conditions. The preparation method of the invention solves the problem that the alginate fiber and a fabric made therefrom are neither salt-resistant nor detergent-resistant. The borate-modified alginate fiber and a fabric made therefrom have excellent salt resistances, and can be washed with an alkaline detergent. The swelling degree of the alginate fiber modified by the adjuvant solution can be reduced to 39.8% after the fiber is immersed in a normal saline at 30°C for 72 h and can be reduced to 55.3% after the fiber is immersed in a standard detergent for 24 h, while the fiber maintains its original morphology without any obvious dissolution phenomenon, and the self flame-resisting performance of the alginate fiber is also maintained.
