Embodiment 1

[0013] The preparation of a kind of nano-graphene oxide modified cotton fiber of the present invention and antibacterial product thereof is characterized in that the preparation method comprises the following steps:

[0014] (1) Add 20g of 50-mesh graphite powder, 10g of potassium persulfate and 10g of phosphorus pentoxide into concentrated sulfuric acid at 80°C, stir evenly, cool for 10h, wash until neutral, and dry. Add the dried sample to 230mL of concentrated sulfuric acid at 0°C, and then add 60g of potassium permanganate. The temperature of the mixture was kept at 10 °C, and after keeping in an oil bath at 30 °C for 2 h, 920 mL of deionized water was slowly added. After 10 minutes, add 2.8 L of deionized water (which contains 50 mL of 30% hydrogen peroxide), after which the color of the mixture turns bright yellow, and it is suction filtered while it is hot, and then washed with 5 L of 10% hydrochloric acid, suction filtered, Dry to obtain graphite oxide;

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a nanometer graphene oxide modified cotton fiber and the preparation of antibacterial products thereof. Background technique [0002] Although natural cotton products have the advantages of wearing comfort, reproducibility and biodegradability, but in the process of wearing, due to the large specific surface area and strong moisture absorption capacity of cotton fibers, cotton products are very easy to attach microorganisms and Create conditions for its reproduction and propagation, resulting in damage to fiber strength, stains and discoloration, unpleasant odors, and even the spread of diseases, affecting human health. Therefore, in the research of cotton fiber modification, an important research direction is to realize the antibacterial properties of cotton fiber and reduce the invasion of bacteria on the human body. [0003] There are usually two methods for the developmen...
