Although natural cellulose has the advantages of wearing comfort, renewability, biodegradability and the like, in the process of taking, as the fiber has larger specific surface area and stronger moisture absorption capacity, the fiber product is easy to attach microorganisms and creates conditions for reproduction and transmission of the fiber product, so that strong damage to the fiber, stain and color fading, unpleasant odor, even disease transmission and influence on the health of a human body are caused. Therefore, in the research of modifying cellulose, an important research direction is to realize the antibacterial performance of cellulose and reduce the invasion of bacteria to human bodies. The nano silver is often used as an antibacterial finishing agent due to the safe, nontoxic and efficient antibacterial performance, has lasting and stable antibacterial performance and strong adaptability, is not easy to generate drug resistance, and has a dominant position in the application of inorganic antibacterial finishing agents.
The preparation method of the nano-silver antibacterial textile mainly comprises a fiber modification method and a fabric post-finishing method. The fiber modification method is that nano silver is added into fiber-forming high polymer, and then wet method or melt spinning is carried out, and then antibacterial fabric is prepared; the fabric after-finishing is to form a nano silver antibacterial layer on the surface of the textile material by coating or dipping the surface of the fabric. Because natural fibers such as cotton, silk and the like are soft in texture, have good affinity to human skin and good moisture absorption, breathability, reproducibility and the like, are widely favored by people and occupy an absolute position in daily life textiles of people. Modification of such natural fibers can only impart antimicrobial properties by post-finishing. Currently, there are many methods for preparing antibacterial fabrics using post-finishing methods, such as dip adsorption, multilayer deposition, sol-gel coating, polymer hybrid coating, supercritical carbon dioxide, and the like. Simple physical adsorption in these methods is often not firm enough, the use of crosslinker fixation or polymer coating to increase the fastness can cause the loss of the original excellent hand feeling of the fabric, affinity to human skin and the like, and the use of these chemical agents can not only pollute the environment, but also cause potential harm to human body when being finished on the fabric.
