“…According to AATCC TM100-2004, 33 control and unchlorinated/chlorinated coated fabric samples were challenged with S. aureus (ATCC 6538) and E. coli O157:H7 (ATCC 43895) using a sandwich test method. 34 The fabrics (0.4 g) were cut into 2.54 × 2.54 cm samples. Bacteria were suspended in pH 7, 100 mM phosphate buffer, and 25 μL of the bacterial suspension were added to the middle of two pieces of the coated cotton samples.…”

To obtain antibacterial properties for colored cotton fabrics, vat dyes were chosen to dye cotton because they can avoid serious discoloration during chlorination. In this study, we synthesized a reactive N-halamine precursor, 4-(4-(2,2,6,6-tetramethyl-4-piperidinol)-6-chloro-1,3,5-triazinylamino)-benzenesulfonate (BTMPT), and coated it on colored cotton fabrics that were dyed with three different vat dyes. The optimum pH for chlorination of the treated cotton fabrics was investigated. Chlorination at pH 11 achieved a small color difference and greater than 0.2% of active chlorine loading. When challenged, the chlorinated fabrics inactivated all inoculated Staphylococcus aureus (Gram-positive) and Escherichia coli (Gram-negative) within 5 min. The treated cotton fabric had greater breaking strength than those treated with the traditional process, as well as good washing stability.

“…Upon exposure to UV light, N -halamines generally tend to decompose, whereas their unchlorinated precursors do not easily degrade. UV light might break the N–Cl bond. − Worley’s investigation found that within 24 h of exposure to UV light, hydantoin-containing N -halamines almost completely lost their oxidative chlorine, but their unchlorinated counterparts showed no significant decomposition during 120 h of exposure, indicating that the presence of N–Cl functionality has an observable effect on the photodegradation process. Kocer’s group compared the stability of 4-piperidinol-containing N -halamines to their unchlorinated counterparts under UV irradiation.…”

Microbial contamination arising from pathogens poses serious threats to human health and in recent decades has presented an unprecedented challenge to antibacterial research. Of the various antibacterial agents that effectively kill pathogens, halogen-based antibacterial compounds have been successful in eliminating harmful pathogen-associated diseases and are becoming the most popular disinfectants. As a significant subcategory of halogen antibacterial agents, N-halamines have drawn increasing research interest into their chemistry and practical applications. N-Halamines have many advantages over other antibacterial agents, including effectiveness against a broad spectrum of microorganisms, long-term physicochemical stability, high structural durability, and the regenerability of their functional groups, with corresponding renewal of their antibacterial properties. This review examines recent progress and research trends in both theoretical and experimental studies of N-halamines, with the aim of providing a systematic and comprehensive survey and assessment of the significant advances in our understanding of antibacterial N-halamines. This review serves as a practical guide to developing N-halamines through both broad and in-depth basic research and offers suggestions for their potential future applications.

“…The high antimicrobial efficiency, long‐term stability and renewable anti‐bacterial ability of N‐halamines make them an ideal anti‐bacterial finishing agent on fabrics 20‐22 . A series of s‐triazine–based reactive N‐halamine precursors have been developed and applied to the preparation of anti‐bacterial textiles 23‐27 . Because they have similar structures to reactive dyes, they can be applied to cotton fabrics with reactive dyes simultaneously, reducing the production of wastewater generated from the independent processes of dyeing and finishing.…”

A reactive dye, Novacron Deep Orange S‐4R, and an anti‐bacterial precursor, 4‐(4‐(2,2,6,6‐tetramethyl‐4‐piperidinol)‐6‐chloro‐1,3,5‐triazinylamino)‐benzenesulphonate, both of which are monohalogenated‐s‐triazine–based compounds, were chosen for the simultaneous dyeing and anti‐bacterial finishing of cotton fabric. To effectively reduce the emissions of pollutants and the dosage of sodium sulphate added during dyeing and finishing, a cationisation reagent, 2,3‐epoxypropyltrimethylammonium chloride, was used to modify cotton fabric before dyeing and finishing. The cationised cotton fabrics obtained 0.18% active chlorine loadings and good dye depth after the simultaneous dyeing and finishing process with low addition of sodium sulphate. The chlorinated fabrics inactivated all inoculated Staphylococcus aureus (Gram‐positive) and Escherichia coli (Gram‐negative) within 10 minutes of contact. The treated cotton fabric maintained high breaking strength as well as good washing stability.
