Current Situation Of Nano Antibacterial Textiles And Antibacterial Technology

In the late 80s of the 20th century, durable antibacterial fibers were obtained through the blending of chemical fibers and antibacterial agents. These antibacterial agents were inorganic, including metal elements, oxides and various compounds.

According to the difference of bactericidal mechanism, they can be classified as contact type antibacterial agent and photocatalytic antibacterial agent.

Due to the development of nanotechnology in recent years, it is possible to mass produce sub micron and nanometer inorganic antibacterial agents, and can be blended into chemical fibers to ensure the industrialization of antibacterial chemical fibers.

Recently, many countries in the world, especially in Japan, the United States and the United Kingdom, have seen the importance of antibacterial fibers. They have developed and produced their own antibacterial fibers and their textiles. Among them, the fibers used to add antibacterial agents to spinning fluid are mostly polyester, acrylic, nylon and so on.

The ultrafine nano antibacterial powder developed by the national super powder engineering center can endow the resin with antibacterial ability and inhibit various bacteria, fungi and mold.

The nano layered silver based inorganic antibacterial fiber, developed by the Chinese Textile Research Institute and Beijing's special agent, uses the ultrafine silver ion phosphate crystalline powder as the inorganic filler. First, the antibacterial masterbatch is mixed with the polyester melt, and then a certain proportion of antibacterial masterbatch is added to produce the permanent antibacterial polyester fiber when spinning.

The antibacterial polyester fiber has the characteristics of insoluble antibacterial agent, no change of fiber color and good spinnability.

Nano resistance technology: the nano silver anti bacterial sports shoes developed by the Institute of physical chemistry and technology of the Chinese Academy of Sciences made XTEP the first international anti-bacterial sports shoes company.

At the same time, it is the first generation of nano silver antibacterial sports shoes in the world, marking China.

Stepping into the field of high and new technology.

Nano antibacterial biological protein fiber technology and achievements: the project of "nano antibacterial biological protein fiber" developed by three companies such as the Institute of process engineering, Chinese Academy of Sciences, uses antibacterial viscose spinning technology to prepare antibacterial functional protein fiber, which is technically innovative and fills the domestic blank and occupies the leading international level.

The invention of this technology marks the first successful docking of modern biotechnology with modern textile technology, marking the beginning of a new high-tech industry leading the world's wool fiber industry revolution and the new generation.

In recent years, nano particle and nano technology based nano powder modified textile polymer materials, nano printing and dyeing technology research and development is flourishing, and has made some achievements in the high-performance and functional aspects of textile products, and has achieved industrialization in various degrees, effectively promoted the development of high and new technology in printing and dyeing industry, and promoted the level of traditional printing and dyeing products.

The important direction of upgrading of antibacterial textiles and upgrading of household textiles.

Antibacterial fiber and antibacterial fabric can effectively prevent microorganisms from propagating and growing on the fabric, which is hygienic and self cleaning, and also has a deodorant effect.

Antibacterial fibers containing antibacterial agents, after washing, surface wear and other strong effects, the antibacterial effect of the fiber almost does not decline.

The key to developing antibacterial fibers is to simultaneously achieve the antibacterial property, safety and requirements of machinability in the spinning process.

Inorganic antibacterial agents are a kind of long-lasting, broad-spectrum, highly effective and safe new antibacterial agents.

In addition, the high temperature resistance of inorganic antibacterial agents can not be achieved by other types of antibacterial agents.

Antibacterial fibers can be achieved through antibacterial masterbatch technology.

Antibacterial masterbatch is a highly concentrated form of antibacterial agents in polymeric materials.

The purpose of using antibacterial masterbatches is to facilitate the dispersion of antimicrobial agents, because antimicrobial agents have undergone a pre dispersion in the masterbatch.

More importantly, the problem of discoloring of antibacterial agents can be inhibited by masterbatch technology, otherwise silver containing antibacterial agents will usually discolor in use or in molded products.
