Development of PET Fabrics Containing N-halamine Compounds with Durable Antibacterial Property

Abstract

Antibacterial textile materials are widely used in daily life, but most are disposable products with poor antibacterial durability. N-halamine can rapidly inactivate microorganisms, has good stability, and shows great potential applications in antibacterial fabrics. In this study, an N-halamine monomer precursor was synthesized and treated onto PET fabrics. The treated PET fabrics were rendered antibacterial functionality after chlorination, and exhibited good antibacterial properties with inactivation rate of 100.0 % for both E. coli O157:H7 and S. aureus. After 50 wash cycles, the chlorinated treated PET fabrics could maintain 80.0 % antibacterial efficacy, demonstrating durable antibacterial properties. Storage stability and UV irradiation tests showed that the treated PET fabrics had remarkable regenerable properties. The reduction of the breaking strength was within 12 % after treatment, which is in a satisfying range in antimicrobial finishing.

N-Halamine-Based Polypropylene Melt-Blown Nonwoven Fabric with Superhydrophilicity and Antibacterial Properties for Face Masks

“…Moreover, compared with the spectrum of MAA, disappear of the C=C bond at 1603 and the C−H bonds at 933 cm −1 in P(MAA-MBAA) nanoparticles, implying that the P(MAA-MBAA) nanoparticles do not contain unreacted monomers, which is similar to the results of Gutman's study [34]. In the XPS spectra (Figure 2e), a strong peak at 399 eV, corresponding to the binding energy of N 1s [38], was observed in the PP-P(MAA-MBAA) MNFs. After chlorination, the PP-P(MAA-MBAA)-Cl MNFs showed significant enhancement at the binding energy of 202 eV, corresponding to the binding energy of Cl 2p, which indicates that the N-H bond in the P(MAA-MBAA) nanoparticles has been transformed into an N-Cl bond [39].…”

Nonleaching Antimicrobial Cotton Fabrics Finished with Hyperbranched Polylysine

“…), and natural products (chitosan, flavonoids, antimicrobial peptides, etc. ). ,− However, the antimicrobial fabrics finished by these antimicrobial agents are mostly leaching types, which exert antimicrobial activities via the release of antimicrobial agents. Their antimicrobial performance depends greatly on the amount of the released antimicrobial agents .…”
