“…The sample treated with corn silk and untreated cotton fabric indicate peaks at 14.9°, 16.5°, 22.6°, and 34.6°correspond to the crystalline structure of cellulose in the cotton fabric. [36] This result showed that the cellulose treatment was not altered the crystalline structure of cellulose I and the sharp peaks of cotton samples remained unaffected.

Concerning the increasing demand for antibacterial nature-based textiles, this work deals with the modification of cotton fabric with corn silk as a natural polymer together with the in situ synthesis of copper (II) oxide nanoparticles.Copper acetate is used as a precursor of copper (II) oxide and ascorbic acid as an environmentally friendly reducing agent. The copper (II) oxide/corn silk nanocomposite cotton fabrics are evaluated by FESEM, XRD, FTIR, water absorption, and antibacterial analysis. The treated fabrics exhibit higher water absorption and FESEM images along with EDX spectra confirm the formation of copper (II) oxide nanoparticles and corn silk layer on the fabric surface. FTIR analysis also establishes effective assembling of CuO/corn silk on the cotton surface. Moreover, the antimicrobial efficiency of the nanocomposite is verified to be higher than 90% against Gram-negative and Gram-positive model bacteria comprising Escherichia coli and Staphylococcus aureus, and antifungal properties against Candida albican. Consequently, the fabrication of copper (II) oxide/corn silk nanocomposites on the cotton fabric could be potentially applied for the preparation of antibacterial medical textiles.

Microbial susceptibility of the denim fabric sized by starch raises some skin health concerns about this extensively used fabric. In this work, biocompatible antibacterial denim fabric is prepared by optimized green synthesis of the copper(I) oxide (Cu 2 O) nanoparticles on the cotton fibers. The copper oxide nanoparticles were synthesized without using any toxic chemical to reduce the copper salt. As an alternative, the waste of the sugar refinery factory, molasses, was used as eco-friendly and cost-efficient material. The antibacterial activity of the samples against Candida albicans as model fungus, Escherichia coli as Gram-negative, and Staphylococcus aureus as Gram-positive model bacteria is investigated besides cytotoxicity; also, the synthesis process is optimized regarding the most biocompatible and antibacterial nanocomposite. The characterizations prove the effectiveness of the molasses for reduction of the copper salt and formation of the copper(I) oxide (Cu 2 O) nanoparticles. Synthesis of the copper(I) oxide (Cu 2 O) nanoparticles has a positive effect on the mechanical properties of the nanocomposite. The results of this work introduce a green method for sustainable development of the fabric industry; it also presents a potential application for molasses and reutilizing it.

Heavy metal ions have detrimental impacts on both the environment and human health. Therefore, it is necessary to develop simple, economical water treatment adsorbents that employ easily modifiable, organic, biodegradable polymers like cellulose nanocrystals. This work used Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), X‐ray diffraction (XRD), and Brunauer–Emmett–Teller (BET) to characterize the cellulose nanocrystal hydrogel prepared to remove Ni2+. The hydrogel was established to have two stable degradation points, ranging from 70 to 120°C to 250 to 380°C. Additionally, the principal functionalized groups observed in the hydrogel's molecular structure were CH, OH, and CO, which were uniform distribution and finger‐like structures as seen by SEM. It consisted of crystalline and amorphous structures, as shown by XRD patterns, making it a viable option for water filtration. BET showed that the surface area of the hydrogel increased upon modification. The column study involves optimization of pH, flow rate, concentration, and bed depth. According to experimental data, the effects of breakthrough parameters including pH (4, 5, 6) influent concentration (50, 75, and 100 mg/L), feed flow rate (5, 10, and 15 mL/min), and bed height (10, 15, and 20 cm). With an adsorption capacity of 58.65 mg/g, a flow rate of 10 mL/min, a bed depth of 20 cm, an influent concentration of 75 mg/L and a pH of 5 was found. The column experimental data fitted better to the Thomas, Yoon–Nelson, and bed depth service time modelling (R2 > 0.99) than the Adams–Bohart model with R2 > 0.90. The adsorbent is economical and environmentally friendly due to its excellent regeneration capacity.
