Antimicrobial agents used in antibacterial finishing require selective activity for undesirable microorganisms, good antibacterial effect, no resistance, washing resistance, disinfection and sterilization. < /p >
In addition, most of the nonwoven antibacterial products are used in medical, pharmaceutical products and personal hygiene products. Therefore, they require no irritation, no toxicity and no pathogenic substances to the skin. P In terms of antibacterial and bacteriostatic effects, inorganic antibacterial agents, especially silver antibacterial agents, have the best effect, and organic antibacterial agents are worse. < /p >
< p > at the same time, because the composition and molecular structure of antibacterial agents are different, their adaptability to finishing methods is different. Therefore, the choice of technology is also very particular: the application of inorganic antibacterial agents is relatively limited; when applying organic antibacterial agents, we should pay attention to the influence of temperature and pH value on the properties of antibacterial agents. For example, some antimicrobials fail at high temperatures or pH values, or their bacteriostatic effects are reduced. < /p >
< p > in addition, the matching principles of various auxiliaries are also important when several < a href= "http://m.pmae.cn/news/index_c.asp" > < /a >. Attention should be paid to the matching principles of all kinds of < a href= "http://m.pmae.cn/news/index_c.asp" > auxiliaries < /a > during the various functions of the same nonwoven material, so as to avoid mutual influence and reduce the effect. < /p >
< p > when bathing in antibacterial and dyeing finishing, we should take into account the antagonism between additives such as adhesives, coatings, penetrants, defoamers, and the effect of antagonistic bacteria, so as to avoid the precipitation of anionic auxiliaries and cationic auxiliaries in the same bath. < /p >
< p > according to the different equipment and the different uses of products, there are other ways to finish the nonwoven antibacterial materials by post finishing methods. For example, the products with less antibacterial requirements can be sprayed with antibacterial agents. For single side antibacterial materials, one side coating process can be adopted, while the production of disinfection wet tissue is directly impregnated. < /p >
