摘要：
A reactive antibacterial monomer, acryloxyethyl dimethyltetracycline ammonium bromide (DEMA-TBr) was synthesized via dimethaminoethyl acrylate(DEMA) and tetracycline bromide (TBr). Subsequently, a low temperature antibacterial finishing process of wool fabric was developed via radical polymerization. The chemical structure of the monomer was analyzed by Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance (NMR), and its antibacterial activity was tested. The tests implied that DEMA-TBr had reactive bond and quaternary ammonium group, which exhibited the excellent antimicrobial activities against E. coli and S. aureus, with the minimum inhibitory concentrations (MIC) 0.04—0.05 mg/mL and 0.03—0.04 mg/mL, respectively. Meanwhile, the treated fabrics were characterized by FTIR and SEM. The optimal finishing process was determined based on the antibacterial rate of fabrics, as well as the antibacterial rate after 20 launderings, treated by different dosage of DEMA-TBr, finishing temperature and time. The results demonstrate that the fabric treated by DEMA-TBr has long-lasting antibacterial properties, and the antibacterial rate is still 100% after 20 laundering times. Besides, the mechanical properties of treated fabric have no decrease significantly, and the retention rate of breaking elongation and breaking strength are both higher than 90%. To sum up, DEMA-TBr has been proven to be a highly active antibacterial agent, and its low-temperature finishing process is expected to replace the traditional high-temperature baking finishing method for long-term antibacterial finishing of wool fabrics. © 2022 Cailiao Daobaoshe/ Materials Review.
