“…3). Compared to pristine cotton, the spectrum of Cotton-Br showed new peaks at 70.1 and 400.3 eV, which corresponded to Br-3d and N-1 s, respectively, and indicated that the cotton had been successfully modified by BiBB (Yu et al 2020). After polymer grafting modification, no remarkable variations in the position and intensity of peaks were observed between Cotton-Br and Cotton-g-PSMA.…”

An N-halamine precursor 2-(3-(6-methyl-4-oxo-1,4-dihydropyrimidin-2-yl)ureido)ethyl methacrylate (SCMHBMA) was synthesized and grafted on cotton fabrics via atom transfer radical polymerization for antibacterial function after chlorination. The preparation and chlorinated cotton fabrics (Cotton-g-PSMA-Cl) were characterized with FTIR, XPS, SEM, and TGA. The properties of prepared Cotton-g-PSMA-Cl, including thermal property, antibacterial efficiency, durability, and stability, were systematically evaluated. The results showed that these chlorinated Cotton-g-PSMA-Cl fabrics possessed excellent antibacterial activity against E. coli. and S. aureus. After 10 washing cycles and 60 days of routine storage, active chlorine concentrations (Cl ? %) were reduced only 22% and 18%, respectively, and the reduced Cl ? % effectively reverted by simple rechlorination. This new N-halamine antibacterial cotton composite with superior antibacterial properties exhibited potential for future application in the longterm antibacterial field.

The results showed that these chlorinated Cotton-g-PSMA-Cl fabrics possessed excellent antibacterial activity against E. coli. and S. aureus. After 10 washing cycles and 60 days of routine storage, active chlorine concentrations (Cl+%) were reduced only 22% and 18%, respectively, and the reduced Cl+% effectively reverted by simple rechlorination. This new N-halamine antibacterial cotton composite with superior antibacterial properties exhibited potential for future application in the long-term antibacterial field.

Preparation of effective membrane with special surface treatment for oil/water separation having promising future and low manufacturing cost. The suggested membrane was fabricated by a simple treatment via increasing the hydrophilicity of the cotton fabric surface. The cotton fabric was impregnated in poly(acrylic acid-co-N-methylol acrylamide), poly(AA-co-NMA), where NMA acts as bonding agent. Sodium hypophosphite (SHP) was added to the modification solution to enhance the bonding between the cotton fabric and the PAA.The modified fabric was thermally dried and cured at different temperatures. It was found that, the presence of 3.5% NMA and addition of 5% SHP to the modification solution then curing at 190 C gave the highest amount of bonded PAA to the cotton fabric. The success of the modification process was confirmed by scanning electron microscope, Fourier transformer infrared and the increase in the contact angle of the cotton fabric after modification. Furthermore, the prepared membrane was evaluated for oil (n-hexane, toluene, and petroleum ether)/water separation and also for heavy metal ions removal (Cd 2+ and Co 2+ ).Neutralization of the produced membrane with ammonium hydroxide resulting in a higher contact angle and consequently higher separation efficiency for oil/water mixtures and higher performance for heavy metal ions removal compared to the unneutralized one.
