Problems solved by technology

[0006] However, the amount of GO that can be accumulated on the surface of the fabric by direct impregnation with ultrasound during the printing and dyeing finishing process is very limited; the existence of impurities is particularly obvious for the GO solution prepared by the Hummers method using the padding method; the cationic modification of the fabric The treatment is limited to the flocculation and bonding of GO on the surface of the fabric, failing to achieve the desired fastness effect

Embodiment 1

[0029] Embodiment 1: the preparation method of antibacterial cotton fabric, flow chart is as figure 1 shown, including the following steps:

[0030] (1) Weigh the graphene oxide prepared above and ultrasonically treat it in water for about 30 minutes to obtain a GO aqueous solution with a concentration of 5 g / L. Before use, clean the solution in an ultrasonic cleaner for 30 minutes at a power of 300w.

[0031] (2) Cut the cotton fabric (10cm*5cm in size) and immerse it in 3g / L CTAB solution for modification treatment for about 1 hour. The temperature of the treatment process is 85°C. Yes, cationically modified cotton fabrics are obtained.

[0032] (3) After drying, the cationic surface-modified cotton fabric was directly immersed in 5g / L GO aqueous solution at room temperature for 20min, then dried at 60°C for 10min, and then immersed in 3% PVP aqueous solution for 20min. Afterwards, the sample was taken out and placed in an oven at 60°C for 10 minutes to dry to obtain a cot...

Embodiment 2

[0035] The steps of this embodiment are the same as those of Example 1, the difference being that the concentration of the GO aqueous solution is 2g / L in the step (1); The phenomenon shows that the concentration of GO aqueous solution has less influence on the finishing effect than that of iodine concentration.

Embodiment 3

[0037] The steps of this embodiment are the same as those of Example 1, the difference being that: in step (1), the 5g / L GO aqueous solution was cleaned for 30min under the condition of 600w power; Treat at 80°C for 30min; in step (3), soak in the PVP aqueous solution with a mass fraction of 5% for 20min; Potassium iodide solution for 10min to remove uncomplexed iodine.

Abstract

The invention provides an antibacterial textile and a preparation method thereof. The preparation method comprises the steps of modifying a textile, dipping the textile into an N-vinyl amide polymer water solution such as graphene oxide and polyvinylpyrrolidone so as to generate a graphene oxide-N-vinyl amide polymer film, carrying out self-assembling on the oxide-N-vinyl amide polymer film and iodine, so as to obtain the antibacterial textile. The antibacterial textile has the beneficial effects that on one hand, the disadvantages of low binding capacity and infirmness of graphene oxide on the surface of the textile are overcome; on the other hand, the excellent biocompatibility among iodine and N-vinyl amide polymers such as graphene oxide and polyvinylpyrrolidone is adequately exerted; and by virtue of the excellent antibacterial property, the antibacterial textile can be applied to the development and use of medical products.

Description

technical field [0001] The invention belongs to the technical field of functional finishing of textiles, in particular to a preparation method of graphene oxide / iodine composite antibacterial textiles. Background technique [0002] Graphene is the new "king of materials" in the 21st century. It has many excellent properties such as high strength, good toughness, transparency and conductivity, and is widely used in research in various fields such as materials, medicine, electricity, and textiles. Graphene is widely used in the functional finishing of textiles. With its excellent properties, it has a significant impact on the electrical conductivity, flame retardancy, water repellency, and UV resistance of the finished fabric. In recent years, the combination of graphene and fabrics for the preparation of flexible electrodes has achieved preliminary results, and graphene is also stepping up to achieve mass production in batteries, conductive textiles, and internal heating. ...
