How To Select Antibacterial Materials To Develop Antibacterial Textiles Under Epidemic Situation

At present, the new crown epidemic is still very serious. In front of life and death, everything is trivial for us. Health is the most important thing.

After the outbreak, there will be many changes in our life, no matter how it changes, it will revolve around the theme of "health and happiness". At present, enterprises have been returning to work, but many owners and researchers have already begun to do so. Future products and health categories must be the trend.

If bacteria and viruses are kept outside the body, textiles will bear the brunt. How should we choose the antibacterial materials? Natural fiber, cotton, linen, wool, and hemp have antibacterial function. Hemp has good antibacterial effect due to its containing hemphenols, but the size of hemp fiber is large, spinnability is poor, functional requirements are relatively high, and the reasons are limited. The remaining cotton wool is the hotbed of bacteria. Considering that bacteria are suitable for growing in moist environment, the synthetic fibers are sorted from low to high according to moisture regain. Polypropylene, polyester, acrylic and nylon can understand why nylon socks are smelly feet. Polypropylene is widely used in masks because of its zero moisture regain and light weight. Recently, melt blown fabric is widely known as a hot term, a super fine polypropylene non-woven fabric. The melt spinneret is directly shaped, and its structure is loose and empty. In addition, electrostatic treatment can well adsorb the bacteria virus on the melt blown cloth, thus playing a barrier role. However, polypropylene fiber is difficult to use in clothing because of its difficult coloring. Therefore, the heavy duty of antibacterial materials is on polyester. At present, many antibacterial materials are made of polyester. The product is silver ion polyester. The antibacterial effect of this material is obvious, and its function is durable. It has been widely recognized. The antibacterial effect of copper and zinc ion polyester is worse than that of silver ions, so as to achieve the effect. The proportion of components is high, and the scope of use of copper and zinc is limited. These silver, copper and zinc are all heavy metals. Polyester is the carrier, and some of them will be attached to the surface of the fiber. Therefore, there will be worry about entering the skin. This is why the European and American countries have restrictions on these heavy metal antibacterial materials.

Another kind of organic antibacterial material is to graft a kind of polymer functional group with antibacterial effect on the two methyl terephthalate. This is modified. Recently, the supercool, which is popular in the market, is an organic antibacterial, rather than silver, copper and other inorganic antibacterial. There is no concern about the harm of heavy metals to the body. Therefore, the use of antibacterial materials should be emphasized. The most widely used antibacterial textiles are finishing with antibacterial agents, which is convenient and fast. However, the most common diseases of the finishing agent are instabilities, washability, and unsustainable functions. Moreover, most antibacterial agents are mainly silver ions, and the risk of heavy metals is greater. There is also a widely used chemical fiber viscose, because it is to extract cellulose from natural fibers to gather together again, so the structure of viscose is relatively loose, and its strength is not high, especially wet strength. In the subsequent production and application process, the functional powder added to viscose is easy to precipitate, so viscose heavy metal antibacterial fiber is more important in textile application. Careful.

It is very important to choose a suitable antibacterial material to develop textiles, which directly determines the quality and effect of antibacterial textiles.
