Investigation of aminolysis routes on PET fabrics using different amine‐based materials

In this study, functionalization of PET fabrics with amino groups was achieved by aminolysis. Aminolysis routes were explored using different amine-based materials including ethylenediamine (EDA), triaminotriethylamine (TAEA) and (3-aminopropyl)trimethoxysilane (APTMS), (3-trimethoxy-silylpropyl)diethylentriamine (TRIAMO) in addition to amino-functionalized silica nanoparticles as amino-silane based reagents. The samples deeply characterized SEM, AFM, XPS. Abrasion tensile tests carried out evaluate the mechanical properties modified fabrics. Results showed that aminolysis conducted EDA TAEA reagents lower performances PET, while dense coatings can be deposited on fibres silane-based act protective layers. APTMS presented improved abrasion resistance compared native PET. antibacterial activity surfaces functionalized also evaluated gram-negative bacterium A. fischeri assay. results textile treated
