Problems solved by technology

However, because the known masks only have the function of filtering air and blocking viruses, the outer surface of the masks is easy to gather germs and viruses.
When a mask without antibacterial and antiviral functions is used in an epidemic area, once bacteria or viruses accumulate, its effectiveness will immediately decrease or even lose its effect, which will increase the probability of infection for users

Abstract

The invention belongs to the technical field of textile fabric processing, and discloses a cotton fabric with an antiviral function and a preparation method thereof. The preparation method comprises the following steps that cellulase treatment and plasma treatment are carried out on a cotton fabric body, the cotton fabric body is impregnated in an ionic liquid containing pyromellitic dianhydride and a gallnut bark extract, dry cleaning and drying are carried out after the cotton fabric body is taken out, the cotton fabric body is impregnated in an ionic liquid containing lycorine and the gallnut bark extract, dry cleaning is carried out after the cotton fabric body is taken out, and drying is carried out to obtain the cotton fabric with the antiviral function. The cotton fabric prepared bythe preparation method has an efficient antiviral effect.

Description

technical field [0001] The invention relates to the technical field of textile fabric processing, in particular to a cotton fabric with antiviral function and a preparation method thereof. Background technique [0002] For infectious diseases such as "SARS", "bird flu", and "new coronary pneumonia", the common prevention method is to wear a mask on the street or in a densely populated place to block the invasion of germs and viruses. However, because the known masks only have the function of filtering air and blocking viruses, the outer surface of the masks is easy to gather germs and viruses. When a mask without antibacterial and antiviral functions is used in an epidemic area, once bacteria or viruses accumulate, its effectiveness will immediately decrease or even lose its effect, which will increase the probability of infection for users. Therefore, there is an urgent need for a mask with lower cost and anti-virus function to be used in virus prevention and control. Co...
