AB  - This study discusses the possibility of supercritical solvent impregnation of polypropylene and polyamide fabrics as well as cellulose acetate in the form of beads and films with pyrethrum extract in order to fabricate functionalized materials with repellent properties. Impregnation experiments were performed at temperature of 40 degrees C and pressures of 10 and 20 MPa in supercritical carbon dioxide. The time of impregnation was varied from 0.5 to 18 h. Loadings of pyrethrum extract into polypropylene fabrics and cellulose acetate films higher than 30% were attainable at 10 MPa. In the case of polyamide fabrics and cellulose acetate beads, the pressure of 20 MPa was needed for obtaining the loadings higher than 11%. Pyrethrum extract release study revealed different capabilities of the tested materials for the repellent release, implying a variety of their possible applications. The impregnated solids were characterized by SEM, DSC, FTIR, Mercury intrusion porosimetry analyses and HPLC analyses.

AB  - This study discusses the possibility of using corona pre-treated polypropylene (PP) non-woven fabric as a support for immobilization of colloidal TiO2 and Ag nanoparticles in order to remove dye C.I. Acid Orange 7 from aqueous solution. Dye removal efficiency by sonocatalysis, photocatalysis and sonophotocatalysis was evaluated on corona pre-treated fabric loaded with TiO2 nanoparticles, corona pre-treated fabric double loaded with TiO2 nanoparticles and corona pre-treated fabrics loaded with TiO2 nanoparticles before and after deposition of Ag nanoparticles. In addition, the stability of PP non-woven fabric during these processes was investigated. The substrates were characterized by SEM, EDX and AAS analyses. The change of the dye concentration was evaluated by UV-VIS spectrophotometry. Unlike sonocatalysis and photocatalysis, complete dye removal from both solution and non-woven fabric was obtained already after 240-270 min of sonophotocatalysis. Corona pre-treated PP non-woven fabric loaded with Ag nanoparticles prior to deposition of TiO2 nanoparticles provided excellent degradation efficiency and superior reusability. Sonophotocatalytic degradation of dye in the presence of all investigated samples was the most prominent in acidic conditions. Although this nanocomposite system ensured fast discoloration of dye solution, TOC values of water measured after sonophotocatalysis were not satisfactory because of PP degradation. Therefore, it is suggested to include TOC evaluation in each case study where different supports for TiO2 nanoparticles are used since these nanoparticles may guarantee the dye removal from solution but the stability of support could be problematic causing even more serious environmental impact.

AB  - The aim of this study was to examine the antimicrobial efficiency and color changes of cotton fabrics
loaded with colloidal silver nanoparticles which were synthesized without using any stabilizer. The influence
of colloidal concentration and consequently, the amount of silver deposited onto the fabric surface,
on antimicrobial activity against Gram-negative bacterium Escherichia coli, Gram-positive bacterium
Staphylococcus aureus and fungus Candida albicans as well as laundering durability of obtained effects
were studied. Although cotton fabrics loaded with silver nanoparticles from 10 ppm colloid exhibited
good antimicrobial efficiency, their poor laundering durability indicated that higher concentrated colloids
(50 ppm) must be applied for obtaining long-term durability. Additionally, the influence of dyeing with
C.I. Direct Red 81 on antimicrobial activity of cotton fabrics loaded with silver nanoparticles as well as the
influence of their presence on the color change of dyed fabrics were evaluated. Unlike color change, the
antimicrobial efficiency was not affected by the order of dyeing and loading of silver nanoparticles.
