Antibacterial Finishing of Compression Garment Fabric Based on Ti₃C₂T_x–Chitosan–APTES Material

Wearing a compression garment (CG) can effectively prevent and treat hypertrophic scars (HS), but the surface of CG is prone to bacterial growth. Therefore, it is particularly important to carry out antibacterial finishing on compression garment fabric (CGF). In order to achieve the purpose of synergistic antibacterial action, improving bacteriostatic rate, and enhancing biological safety, this study prepared a composite material of MXene (Ti 3 C 2 T x ), chitosan, and amino silane coupling agent (3-aminopropyl)triethoxysilane (APTES) and its antibacterial CGF. The binding mechanism between the antibacterial composite material and the CGF was explored, and the bacteriostatic rates, wearing properties, and wash fastness of the antibacterial CGF were studied. Results showed that Ti 3 C 2 T x, chitosan, and APTES were covalently bonded to the CGF, achieving synergistic antibacterial effects. The antibacterial CGF without washing showed a bacteriostatic rate of 99.9% against both Gram-negative bacteria Esherichia coli ( E. coli, AATCC 6538) and Gram-positive bacteria Staphylococcus aureus ( S. aureus, AATCC 25922), with washing fastness reaching grade AA. Additionally, the comfort of the antibacterial finishing fabric was affected to a certain extent in terms of flexural rigidity and air permeability, but overall, the wearability of the antibacterial CGF also met the daily wearing needs of patients.
