AB  - This study discusses the biodegradation behavior of cotton and cotton/PET fabrics impregnated with Ag/TiO2 nanoparticles in soil. Biodegradation behavior was evaluated by standard test method ASTM 5988-03 based on determination of percentage conversions of carbon content to CO2 as well as by soil burial test and enzymatic hydrolysis with cellulase where the extent of biodegradation was estimated by the calculation of fabric weight loss. The morphological and chemical changes of fibers during biodegradation process were analyzed by SEM and FTIR spectroscopy, respectively. The results obtained by all applied methods suggested that Ag/TiO2 nanoparticles hindered the biodegradation of investigated cotton and cotton/PET fabrics. Soil burial test indicated faster biodegradation of the impregnated blend compared to impregnated cotton fabric which is attributed to smaller amount of fabricated Ag nanoparticles on the blend proved by MS measurement. Similar trend was established by enzymatic hydrolysis of cotton fibers. Severe damage of cotton fibers in both fabrics due to biodegradation process was confirmed by SEM. However, the cotton fiber damage occurred to a lesser extent in the samples that were impregnated with Ag/TiO2 nanoparticles. PET fibers remained intact which was also indicated by FTIR analysis.

AB  - The possibility of in situ photoreduction of Ag+ using colloidal TiO2 nanoparticles deposited on the surface of polyamide fabric in the presence of the amino acid alanine and methanol is discussed. The presence of TiO2/Ag nanoparticles on the polyamide fabric was confirmed by FESEM and ICP analyses. The antibacterial activity of the fabric was tested against the Gram-negative bacterium Escherichia coli and the Gram- positive bacterium Staphylococcus aureus. The TiO2/Ag nanoparticles fabricated on the surface of the polyamide fabric provided maximum bacterial reduction and thus, excellent antibacterial activity. In spite of silver leaching from the fabric during washing, the impregnated polyamide fabric preserved the maximum reduction of E. coli colonies. The antibacterial activity against S. aureus was slightly decreased after ten washing cycles, but still the antibacterial activity could be considered as satisfactory. In addition, the presence of TiO2/Ag nanoparticles ensured better UV protection efficiency, which belonged to the UV protection category very good.
