A long-lasting antibacterial fabric and its preparation process
By pretreating the fabric with a compound protease and terminal carboxyl polyamide amine, combined with nano zinc oxide and ε-polylysine, a polydopamine adhesion layer is formed, which solves the problem of unstable antibacterial properties of the fabric, improves durability and antistatic properties, and extends service life.

Abstract
This invention relates to the field of antibacterial fabric technology, and more particularly to a long-lasting antibacterial fabric and its preparation process. The preparation process of the aforementioned long-lasting antibacterial fabric includes the following steps: adding a complex protease to water and stirring until homogeneous; adding terminal carboxyl-terminated polyamide amine and stirring for 10-30 minutes; adjusting the pH of the system to 7.5-8; adding wool fabric; stirring in a constant temperature water bath at 35-40°C for 2-4 hours; washing and drying to obtain the pretreated fabric; adding nano-zinc oxide and tris(hydroxymethyl)aminomethane to a dopamine aqueous solution; adjusting the pH of the system to 8-8.5 and stirring for 5-15 minutes; adding the pretreated fabric and stirring for 4-6 hours; adding ε-polylysine and continuing stirring for 2-4 hours; filtering, washing, and drying. This invention provides a scientifically sound and innovative method for high-performance antibacterial treatment of wool fabric through the synergistic effect of multiple components, and the preparation method is simple and low-cost.
