The common fabric has larger surface area and stronger moisture absorption capacity, bacteria are easy to adhere and reproduce, the fabric fiber is faded and the mechanical strength of the fabric fiber is reduced, and special odor is generated, so that infection or disease transmission can be caused, and even the life health of a user is seriously damaged. Therefore, it is necessary to impart an antibacterial function to the fabric to reduce the invasion of bacteria to the human body. The antibacterial agent determines the antibacterial property of the fabric and mainly comprises an inorganic antibacterial agent, an organic antibacterial agent and a composite antibacterial agent. Wherein, the inorganic antibacterial agent has the advantages of broad antibacterial spectrum, heat resistance, durability and the like, and is a commonly used antibacterial agent in the fields of medical treatment, health care, daily chemical industry and the like.
In recent years, nano silver (Ag) has become a novel representative inorganic antibacterial agent due to its characteristics of broad antibacterial spectrum, high antibacterial activity, high safety, difficulty in generating drug resistance, and the like, and is widely used in the fields of medical treatment, clothing, and the like. The antibacterial property of the nano Ag comes from the release of Ag +, the antibacterial mechanism is that silver ions react with sulfur-containing groups in cell membrane proteins to directly destroy cell membranes and increase the permeability of the cell membranes, and the silver ions penetrate through the cell membranes to enter cells and act on respiratory chain proteins and block DNA replication, so that bacteria die and the aim of sterilization is achieved.
At present, the preparation method of the nano-silver antibacterial fabric mainly comprises the following steps: 1) Preparing nano silver and a polymer into a spinning solution, and preparing an antibacterial fabric through electrostatic spinning; 2) Bonding a polymer adhesive to the carbon fiber cloth, and then spraying nano silver on the adhesive, so that the nano silver is adhered to the surface of the carbon fiber cloth through the adhesive; 3) Preparing mixed solution of nano silver and polymer, and adhering the nano silver to the surface of the carbon fiber by adopting dipping-rolling treatment to prepare the antibacterial composite material.
However, the existing preparation method of the nano-silver antibacterial fabric has the following disadvantages: 1) The polymer binder is introduced for enhancing the adhesive force between the nano silver and the fabric fiber, so that the cost is increased and the environment is not protected; 2) The nano silver is easy to be completely wrapped by the polymer binder, thereby reducing the release of Ag +, and reducing the antibacterial activity of the Ag +; 3) Electrostatic spinning, successive coating of a binder and nano-silver, and dipping-rolling treatment, which are relatively complex and are not beneficial to efficiently producing the nano-silver antibacterial fabric.

The test results of the embodiments 1 to 3 show that the plasma treatment of the fabric is beneficial to improving the antibacterial performance of the fabric, when the treatment power of the plasma is too low, the antibacterial performance of the fabric is affected, the bacteriostatic action of the prepared antibacterial fabric on escherichia coli and staphylococcus aureus is reduced, when the treatment power of the plasma is too high, the effect of the power on the antibacterial fabric is smaller and smaller, and the antibacterial effect of the antibacterial fabric is optimal when the plasma power is controlled to be 1800W.
The test results of the embodiment 1, the embodiment 4 and the embodiment 5 show that the antibacterial performance of the fabric can be affected by the content of the silver nanowires in the nano silver antibacterial dispersion liquid, when the content of the silver nanowires is too low, the antibacterial effect of the fabric on escherichia coli and staphylococcus aureus is reduced, when the content of the silver nanowires is increased, the antibacterial performance of the corresponding fabric is also better, when the content of the silver nanowires is too high, the cost is too high, the uneven dispersion of the silver nanowires in a solvent is easy to occur, and the antibacterial performance of the fabric is further affected.
