“…The band located at 1711 cm -1 which is assigned to C=O vibrations of the carboxylic acid groups of CMC (Abidi, 2005). The band centered at about 1590 cm -1 is due to antisymmetrical vibration of the ionized carboxyl groups COO - (Petropavlovskii, 1984). Therefore these bands are indicative of the presence of CMCF on the cotton sample.…”

“…The spectra of CMC-PEG-EG hydrogel exhibited a major peak at 3276 cm −1 due to intermolecular hydrogen bond (Liang and Marchessault, 1959); 2888 cm −1 was assigned to a hydrocarbon grougCH 2 stretching and 1712 cm −1 to a carbonyl group C=O stretching. An antisymmetrical vibration of the ionized carboxyl group COO-appeared at the band 1594 cm −1 (Petropavlovskii et al, 1984), the peak of the scissoring bending vibration of CH 2 was observed at 1419 cm −1 , and the bending vibration of CH was noticed at 1323 cm −1 (Hiroyuki 2014). The band limited to 1021 cm −1 was assigned to C-O of the stretching vibration of the cellulose fundamental (Adebajo and Frost 2004), whereas the band associated with 1249 cm −1 was attributed to C-O (alcohol).…”

Cotton fabrics are usually used for medical purposes, but they can be damaged when exposed to microorganisms. Through modification with carboxymethyl cellulose–polyethylene glycol–ethylene glycol hydrogel/silver/copper oxide (CMC–PEG–EG/Ag/CuO) nanocomposites and subsequent irradiation using an electron beam accelerator, this study proposes an effective method for avoiding bacterial risks on cotton fabrics. The results showed that cotton fabrics loaded with CMC–PEG–EG/Ag/CuO had a low water vapor permeability (WVP) value of 0.09 (0.006% for Ag and 2% for CuO) at a dose of 5 kGy compared with unloaded cotton fabrics (0.33). The tensile strength of the modified cotton fabrics, which had various formulations, was significantly improved with EB irradiation until 25 kGy, exceeding that of the unloaded fabrics. Thermal stability was enhanced by adding CuO nanoparticles up to 2%. The antibacterial activity of the modified cotton fabrics was analyzed by examining gram-negative and gram-positive bacteria. The results showed that the modified cotton fabrics had the highest inhibition zone effect, with 20 and 15 mm for both gram-negative and gram-positive bacteria, respectively. In addition, CMC–PEG–EGs incorporated with 0.006% Ag and 0.012% CuO irradiated at a dose of 5 kGy and 0.006% Ag and 0.5% CuO at a dose of 25 kGy were the most efficient formulations. Meanwhile, a 0.012% concentration of CuO nanoparticles in the formulation was considered appropriate to provide the best antimicrobial activity, as the cost of modifying the fabrics was minimized.
