Skin loss can be caused by accident, burn, trauma, chronic wounds, and diseases, which is severely aggravated by multidrug‐resistant bacterial infections. Soft hybrids based on biopolymers combined with silver nanoparticles (AgNPs) have potential applications as wound dressing supports and skin tissue repair. Thus, our study focused on the design, green synthesis, and comprehensive characterization of carboxymethyl cellulose (CMC–AgNP) nanocomposites for producing hydrogel membranes, with tunable physicochemical properties, cytocompatibility, and biocidal activity for potential application as wound dressing and skin repair. These nanocomposites were prepared using CMC with two degrees of carboxymethylation, distinct concentrations of citric acid (CA) crosslinker, and AgNPs by in situ chemical reduction, forming hybrid membranes by the solvent casting method. The results demonstrated that superabsorbent hydrogels were produced with swelling and degradation behaviors dependent on the concentration of CA crosslinker, degree of carboxymethylation of CMC, and content of AgNP in the matrices. Moreover, the Fourier transform infrared spectroscopy analysis evidenced that the CMC functional groups (e.g., COOH and OH) were directly involved in the chemical reactions for the formation of AgNPs and hydrogel crosslinking pathway. These nanocomposites were cytocompatible using in vitro 3‐(4,5‐dimethyl‐2‐thiazolyl)‐2,5‐diphenyltetrazolium bromide cell viability assay with of human embryonic kidney cells. Conclusively, the CMC–AgNP nanohybrids demonstrated to be simultaneously non‐toxic combined with highly effective antibacterial activity against gram‐positive multi‐resistant wound/skin pathogens (Staphylococcus aureus) and moderate effect towards gram‐negative strains (Escherichia coli and Pseudomonas aeruginosa). © 2017 Wiley Periodicals, Inc.

“…While the individual spectra show the prominent C-O bending peaks (1185 cm −1 -950 cm −1 ) [26,29,30], the features show great distortion when compared to a routine spectrum collected with a benchtop ATR accessory ( Figure 1b). The band distortion is especially heightened for the OH region (3600-3000 cm −1 ), the CH region (3000-2700 cm −1 ), and part of the fingerprint region that typically showcases O-H and C-H bending modes (1500 and 1150 cm −1 , respectively) [26,29,30]. A chemical image (infrared distribution map) of a cotton bundle is shown in Figure 2.…”

Infrared imaging is gaining attention as a technique used in the examination of cotton fibers. This type of imaging combines spectral analysis with spatial resolution to create visual images that examine sample composition and distribution. Herein, we report on the use of an infrared instrument equipped with a reflection accessory and an array detector system for the examination of cotton fiber bundles. Cotton vibrational spectra and chemical images were acquired by grouping pixels in the detector array. This technique reduced spectral noise and was employed to visualize cell wall development in cotton fibers bundles. Fourier transform infrared spectra reveal band changes in the CO bending region that matched previous studies. Imaging studies were quick, relied on small amounts of sample and provided a distribution of the cotton fiber cell wall composition. Thus, imaging of cotton bundles with an infrared detector array has potential for use in cotton fiber examinations.

Capsulation technology is one of the methods that have been utilized for gaining various functional properties of textile materials. With the technology, in recent years, textile materials have been made to exhibit functions such as vitamins, fragrances, moistening effect, insect repellent, and anti-cellulite. To establish permanent bonding between capsule-based materials and textile materials, which also provides efficiency against washing, crosslinking agents are used. Commercial capsules are applied to a fabric by using acrylics or polyurethanes as the cross-linker at a drying temperature of around 100 C and thermo-fixation conditions are between 110 and 130 C. The capsules used for fragrance and aromatherapy applications, which contain volatile oil, can be affected in high-temp conditions that cause evaporation and degradation of active ingredient. In this study, beta-carotene as the active ingredient was dispersed within ethyl cellulose via spray drying first and then applied to textile materials to maintain the tanning effect. Besides thermal curing, the UV curing process with different photoinitiators will be utilized for the fixation of capsules onto textile materials. Hence, the UV curing technique will be used as an alternative to the thermal fixing of conventional cross-linkers. After application of the capsules onto textile materials, characterization, and various efficiency tests such as color measurement, X-ray diffraction, thermogravimetric
