Abstract The organosilicon quaternary ammonium salt/(zinc oxide@carbon quantum dots) composite material referred to P(DMDAAC-AGE-Si)/ (ZnO@CQDs) was prepared with ZnO, glucose and vinyl monomers by situ free-radical polymerization, which was applied into cotton fabrics at different concentrations. It was proved that the antibacterial cotton fabrics had been successfully prepared by FTIR, SEM, TEM, antibacterial tests (shake flask tests) etc. The antibacterial rate was 98.38% and 99.53% against S. aureus and E. coli, respectively, when the concentration of the treating solution of composites
reached to 25 g/L. Even after washing 10 times (equivalent to 50 household washing), the antibacterial rate remained above 89.65% against S. aureus and E. coli. In addition, the hydrophilic properties and air permeability of the treated cotton fabrics were enhanced. Keywords Cotton Antibacterial Skin affinity Durable ZnO@CQDs

With the improvement of national living standards, more and more attention is paid in the sanitary properties of cotton fabrics. As a necessity in our daily life, cotton fabrics have strong hygroscopic performance, good air permeability (Roma´n et al. 2019), and excellent affinity with the human body (Ibrahim et al. 2010). However, it is the porous structure that provides a favorable environment for the growth and propagation of bacteria, which leads to poor microbial resistance in the process of use (Ranjbar-Mohammadi 2018). At the same time, bacteria and their metabolites destroy cotton fabrics and make cotton fabrics smelly, moldy, and some other changes, which will shorten service life and endanger people’s life and health (Xu et al. 2019; Lin et al. 2018). Therefore, it is more and more necessary to develop a kind of cotton textile-based antibacterial
