Abstract

The invention discloses a preparation method of an anti-influenza virus fabric. The method is characterized by comprising the following steps of S1, preparing a 2, 6-diaminopurine / imidazole-4,5-dicarboxylic acid condensation polymer; S2, ionizing the condensation polymer; S3, performing fabric forming; and S4, performing ion exchange. The invention further provides the anti-influenza virus fabric prepared according to the preparation method of the anti-influenza virus fabric. The anti-influenza virus fabric disclosed by the invention is remarkable in anti-influenza virus effect, good in performance stability, and excellent in washing resistance, moisture absorption and sweat releasing effects, water resistance and antistatic performance.

Description

technical field [0001] The invention relates to the technical field of functional textile products, in particular to an anti-influenza virus fabric and a preparation method thereof. Background technique [0002] Textiles, especially fabrics that are close to the skin, form a microenvironment with sufficient nutrients and a temperature and humidity suitable for microbial reproduction under the joint action of skin, fabric and sweat, which leads to a large number of rapid multiplication of various microorganisms and causes various diseases. disease. In particular, once the influenza virus transmitted through the air enters the body, it can seriously affect the health of the body, especially the elderly, children and people with weak resistance. Therefore, the development of fabrics with significant anti-influenza virus effects is a new direction of social research today. [0003] At present, the commonly used preparation methods of antibacterial and anti-influenza virus fabr...
