Description

  The present invention relates to an antibacterial processing method for fiber products and an antibacterial fiber product obtained by this method.

  In recent years, anti-bacterial processing of articles that come into contact with the human body or instruments is becoming natural as hospital infections and contamination problems due to bacteria such as foods frequently occur in hospitals. As for the antibacterial processing of textile products, the fiber technology evaluation council (hereinafter abbreviated as “textile technology cooperative”) established the standards ahead of other industries, and certified fiber products according to the level of antibacterial properties. It is carried out.

  Traditional antibacterial processing in the textile industry suppresses the growth of bacteria on textile products after the textile products are contaminated with bacteria, and secondarily suppresses the generation of malodors resulting from the growth of bacteria. The purpose is to do. By the way, the conventional antibacterial processing of textile products does not suppress the contamination of the textile products by bacteria itself, and even though the imparted antibacterial properties suppress the growth of bacteria, it can be instantly sterilized. There is no effect. Therefore, when bacteria come into contact with the textile product, the bacteria adhere to it, and after that, it becomes alive to some extent. If this comes into contact with the human body, instruments, etc., contamination by bacteria may spread. As described above, even a textile product subjected to antibacterial processing can serve as a medium for bacterial contamination, so that it is not a fundamental measure for the contamination problem.

  For example, antibacterial agents such as inorganic antibacterial agents such as silver and zinc oxide, pyridine antibacterial agents such as zinc pyrithione, and cationic antibacterial agents such as benzalkonium chloride and polyhexamethylene biguanide, which have been conventionally used, There is no effect to suppress the adhesion, and it cannot prevent the textile product from becoming a contamination medium.

  From such a current situation, in general hospitals as well as hospitals, it is difficult for bacteria to adhere so that textiles do not become a medium for bacterial contamination, and as a secondary measure, bacterial growth can be suppressed even when bacteria are attached. The antibacterial fiber product is starting to be demanded.

  In the examples of the present invention, both immediately after processing and after washing showed good antibacterial adhesion and antibacterial properties. On the other hand, in the comparative example, there was nothing particularly showing the adhesion prevention property of the bacteria.

  The present invention has a fungus adhesion inhibitory property and an antibacterial property, so that the fungus adherence is suppressed, and the possibility that it itself can be a medium of fungal contamination is reduced. Since it is possible to provide an antibacterial fiber product that is possible, it is industrially useful.
