Problems solved by technology

[0006] Carbon fiber cloth is a commonly used material for clothing and insoles. The conventional addition of antibacterial materials is usually to directly coat a layer of antibacterial materials on its surface, or mix a part of antibacterial materials, but the combination of antibacterial materials and carbon fiber cloth is not firm. The number of times of use of clothing (the number of washings has the greatest impact) increases and the antibacterial performance decreases significantly. The main reason is that the combination of antibacterial nanomaterials and inorganic carriers is not firm. Therefore, it is necessary to develop a method that can enhance the combination of antibacterial nanomaterials and inorganic carriers The simple preparation process is particularly important

Abstract

The invention provides an efficient and lasting antibacterial material and a preparation method thereof. The preparation method comprises the following steps: cleaning bamboo charcoal fiber cloth, treating under dielectric barrier discharge equipment, and evaporating Ag nanocrystalline crystal seeds; sequentially dissolving a certain amount of polyvinylpyrrolidone, ethylene glycol and succinic acid in deionized water to form a solution A, then adding the bamboo charcoal fiber cloth plated with a layer of Ag nano crystal seeds into the solution A, then dropwise adding a silver nitrate solution with a certain concentration, intensely stirring, and meanwhile, gradually heating to a certain temperature to obtain the bamboo charcoal fiber cloth (at) Ag; and carrying out ball-milling crushing, removing an unattached Ag material and the like to obtain the efficient and lasting antibacterial material with uniform particles and high combination degree. The method is simple in preparation process, low in equipment requirement, high in controllable degree and capable of remarkably improving the combination degree of the Ag nano material and a carrier (bamboo charcoal fiber), so that the antibacterial effect is lasting and efficient, and the method is widely applied to the fields of the clothing industry, the chemical industry and the like.

Description

technical field [0001] The invention belongs to the technical field of nanometer material and preparation technology of clothing industry, and relates to a high-efficiency and durable antibacterial material and a preparation method thereof. Background technique [0002] With the rapid development of social economy, people's awareness of antibacterial health care in the living environment is gradually strengthened. In order to effectively and reasonably prevent antibiotics from being abused, excellent functional antibacterial materials have become daily necessities. At present, functional antibacterial materials can be classified into organic antibacterial materials and inorganic antibacterial materials according to their chemical composition. Organic antibacterial materials have the advantages of fast sterilization and high efficiency, but they have disadvantages such as poor heat resistance, easy hydrolysis, short validity period, and large side effects. At present, the saf...
