Embodiment 1

[0037] The preparation method of the bionic cocklebur type antibacterial and antiviral plant fiber comprises the following steps:

[0038](1) Weigh 30 grams (dry mass) of bleached spruce softwood chemical pulp, add 970 mL of deionized water to make the concentration 3%, soak for 4 hours at a temperature of 20 ° C, then add 500 mL of deionized water to adjust the fiber concentration Dissociate at a temperature of 20°C with a standard fiber disintegrator, and the rotation speed of the propeller is 20,000, so that the plant fibers are evenly dispersed into a single fiber state.

[0039] (2) The decomposed plant fiber obtained in step (1) is concentrated to a concentration of 10% with a Buchner funnel, placed in a PFI mill for mechanical beating, the beating temperature is 20°C, and the beating concentration is 10%. , the number of beating rotations is 20000 rpm, and the degree of beating of the plant fibers after beating is 82.4°SR, thereby obtaining cocklebur-type plant fibers. ...

Embodiment 2

[0045] The preparation method of the bionic cocklebur type antibacterial and antiviral plant fiber comprises the following steps:

[0046] (1) Take by weighing 30 grams (absolutely dry mass) of bleached hemlock softwood chemical pulp, add 1470 mL of deionized water to make the concentration 2%, soak for 6 hours at a temperature of 20 ° C, and then use a standard fiber disintegrator at 20 Dissociation is carried out at a temperature of ℃, and the rotation speed of the propeller is 20,000 revolutions, so that the plant fibers are evenly dispersed into a single fiber state.

[0047] (2) The decomposed plant fiber obtained in step (1) is concentrated to a concentration of 10% with a Buchner funnel, placed in a PFI mill for mechanical beating, the beating temperature is 20°C, and the beating concentration is 10%. , the number of beating revolutions is 20,000 rpm, and the beating degree of the plant fiber after beating is 84.4°SR, thereby obtaining the cocklebur type plant fiber.

Abstract

The invention belongs to the technical field of preparation of antibacterial and antiviral fiber materials, and discloses a preparation method of bionic xanthium sibiricum type antibacterial and antiviral plant fibers. The surfaces of plant fibers are finely fiberized by a mechanical pulping method to prepare the xanthium sibiricum type plant fibers, so that the specific surface area and porosityof the plant fibers are increased, therefore, the in-situ oxidation generation amount of polyaniline on the surfaces of the plant fibers is increased; and then a glucose solution is used for assistingthe reinforced polyaniline in reducing silver ammonia ions on the surfaces of the plant fibers in situ to generate nano-silver, and the xanthium sibiricum type plant fibers with antibacterial and antiviral properties are obtained. The antibacterial rate of the bionic xanthium sibiricum type antibacterial and antiviral plant fiber prepared by the method to escherichia coli, staphylococcus aureus and candida albicans is greater than 99.9%, and the antiviral activity value (Mv) of the bionic xanthium sibiricum type antibacterial and antiviral plant fiber to influenza A H1N1 virus is greater than3.0.

Description

technical field [0001] The invention relates to the field of preparation of antibacterial and antiviral fiber materials, in particular to a preparation method and application of bionic cocklebur type antibacterial and antiviral plant fibers. Background technique [0002] With the development of social economy, the improvement of medical level and the improvement of medical and sanitary conditions, people's demand for medical protective equipment and materials is increasing. The global annual market sales of medical and health non-woven materials exceed 7 billion US dollars, of which spunlace non-woven fabrics account for 35% of medical non-woven materials, with an annual growth rate of 7%, and will continue to grow in the future . At present, conventional spunlace nonwoven products include medical surgical gowns, medical dressing materials, wound dressings, masks, bandages, etc. In the future, spunlace non-woven materials will also develop into the field of multifunctional...
