AB  - A novel impregnation process for the fabrication of cotton nanocomposite with strong antimicrobial activity against antibiotics-resistant bacteria and yeast was developed. The impregnation process includes the sol-gel treatment of fabric with (3-aminopropyl)triethoxysilane in the first step, and synthesis of the CuO/Cu2O nanoparticles (NPs) on the fabric surface in the second step. The in situ synthesis of the CuO/Cu2O NPs was based on the adsorption of Cu2+-ions by the introduced amino groups of the sol-gel coating. The adsorbed Cu2+-ions are subsequently reduced in the alkaline solution of NaBH4. X-ray diffraction measurements confirmed the formation of CuO/Cu2O NPs. Scanning electron microscopy and atomic absorption spectrometry analyses indicate that the particle size, agglomeration, and amounts of synthesized NPs were highly affected by the initial concentration of CuSO(4)solution. The toxicity of nanocomposites to human keratinocytes (HaCaT) and antimicrobial activity against Gram-negativeEscherichia coliATCC 25922,E. coliATCC BAA 2469, andKlebsiella pneumoniaeATCC BAA 2146, and Gram-positive bacteriaStaphylococcus aureusATCC 25923,S. aureusATCC 43300 and yeastCandida albicansATCC 24433 strongly depended on the copper content. In addition to excellent antimicrobial activity, controlled release of Cu2+-ions from the fabrics into physiological saline solution was obtained.

AB  - Commercial P25 TiO2 nanoparticles are widely exploited as an efficient photocatalyst. In the textile domain, these nanoparticles are used for the production of self-cleaning, highly UV protective textiles, with an antimicrobial activity. The disposed textile products may end up in a landfill where they are subjected to the biodegradation process. Considering the importance of the later, this study discusses the biodegradation behaviour of cotton fabric impregnated with commercial P25 TiO2 nanoparticles. Photocatalytic activity of TiO2 nanoparticles immobilized on cotton fabric was proved by the photodegradation of dyes C. I. Acid Orange 7 and methylene blue in aqueous solution. Biodegradation of fabrics was assessed by soil burial test in periods of 3, 9 and 18 days. Chemical and morphological changes induced by biodegradation were analyzed by FTIR, SEM and EDS. A colour of the samples gradually changed from white to yellow/brown due to rotting. SEM analysis revealed a severe destruction of the control and impregnated cotton fibres after 18 days of soil burial which was in line with visual appearance of completely damaged fabrics. The results confirmed that biodegradation behaviour of both the control and impregnated sample was equivalent, indicating that P25 TiO2 nanoparticles did not inhibit the biodegradation process of cellulose.

AB  - This study discusses the effect of corona pre-treatment at atmospheric pressure and subsequent loading of colloidal TiO2 nanoparticles on the biodegradation behavior of cotton fabric. Biodegradation performance of the control and finished samples was evaluated by standard soil burial tests in predetermined periods of 3, 9 and 18 days. Color and breaking strength measurements were utilized for assessment of biodegradation progress. Morphological and chemical changes induced by biodegradation were analysed by SEM and FT-IR analyses, respectively. Colorimetric, morphological and chemical changes induced by the biodegradation process were slightly less prominent on corona pre-treated cotton fabric impregnated with TiO2 nanoparticles compared to corona treated and control cotton fabric. Although the breaking strength of all samples significantly decreased after 18 days of soil burial, this decline was the least evident on the sample impregnated with TiO2 nanoparticles. However, taking into account the extent of these differences, the influence of TiO2 nanoparticles on biodegradation rate of cotton fabric, which underwent a combined treatment corona/impregnation with TiO2 nanoparticles, could be considered as insignificant. These results confirm that chemical modification of cotton fabrics with plasma and subsequent loading of TiO2 still maintained sustainability of cellulose fibres.
