AB  - In this study the possibility of tailoring the textile nanocomposite materials based on the polyester fabric and TiO2 nanoparticles that can simultaneously provide desirable level of antibacterial activity, UV protection, and self-cleaning effects with long-term durability was investigated. To enhance the binding efficiency of colloidal TiO2 nanoparticles, the surface of polyester fabrics was activated by low-pressure RF air plasma, and corona discharge at atmospheric pressure. Obtained functionalized textile materials provided maximum antibacterial efficiency against gram-negative bacterium E. coli. High values of UV protection factor (UPF) indicate the maximum UV blocking efficiency (50+) of these fabrics. The results of self-cleaning test with blueberry juice stains and photodegradation of methylene blue in aqueous solution confirmed excellent photocatalytic activity of TiO2 nanoparticles deposited on the fiber surface.

AB  - The objective of this study was to highlight the potential application of the corona discharge at atmospheric pressure for the surface activation of polyester (PES) fabrics in order to improve the binding efficiency of colloidal TiO2 nanoparticles. The obtained nanocomposite textile materials provide desirable level of UV protection, self-cleaning properties, and photodegradation activity. The measured UV protection factor (UPF) of fabrics corresponds to UPF rating of 50+, designating the maximum UV protection. Additionally, the total photodegradation of methylene blue in aqueous solution was achieved after 24 hr of UV illumination and this capability was preserved and even improved after four repeated cycles. The results showed that the corona treated PES fabrics loaded with TiO2 nanoparticles had considerably enhanced the overall efficiency compared to PES fabrics loaded only with TiO2 nanoparticles.

AB  - The potentials of low-pressure capacitively coupled RF oxygen and argon plasmas for the activation of polyester fibers surface that can enhance the deposition of colloidal TiO2 nanoparticles were discussed. SEM and XPS analysis confirmed the plasma-induced morphological and chemical changes on the surface of polyester fibers. Oxygen and argon plasma pretreated polyester fabrics loaded with TiO2 nanoparticles provided maximum reduction of Gram-negative bacteria E. coli and UV blocking. The self-cleaning effects tested on blueberry juice stains and photodegradation of methylene blue in aqueous solution proved excellent photocatalytic activity of TiO2 nanoparticles deposited onto fiber surface. Although both plasmas significantly contributed to overall improvement of properties of such nanocomposite textile material, oxygen plasma treatment, in particular, enhanced the deposition of colloidal TiO2 nanoparticles and thus ensured superior effects.

AB  - This study discusses the possibility of using the corona (electric discharge at atmospheric pressure) treatment for fiber surface activation that can facilitate the loading of Ag nanoparticles (NPs) from colloids onto the polyester and polyamide fabrics and thus enhance their antifungal activity against Candida albicans. The laundering durability of achieved effects and the influence of dyeing of fabrics with disperse dyes on their antifungal efficiency were studied. The morphology of fibers loaded with Ag nanoparticles was characterized by SEM whereas X-ray photoelectron spectroscopy was used for the evaluation of surface chemical changes. Corona pretreated polyester and polyamide fabrics loaded with Ag nanoparticles showed better antifungal properties compared to untreated fabrics. The advantage of corona treated fabrics became even more prominent after washing test, particularly for polyester fabrics. Antifungal efficiency of polyester and polyamide fabrics loaded with Ag nanoparticles were almost unaffected by dyeing process.

AB  - This study examines in detail the influence of low-temperature plasma and biopolymer chitosan treatments on wool dyeability. Wool knitted fabrics were treated and characterized by whiteness and shrink-resistance measurements. Surface modification was assessed by contact-angle measurements of human hair fibers, which were used as a model to study the wetting properties of the treated wool knitted fabrics. The dyeing behavior was assessed from the diffusion mechanism point of view. The dyeing kinetics were measured at two different pHs (4.2 and 6.5) and three different temperatures (60, 85, and 100 degrees C) to gain information about the contribution of the surface modification treatment to the dyeing mechanism. The exhaustion and reflectance data were compared, and the apparent diffusion coefficients were calculated. On the basis of the obtained results, a model for the dyeing mechanism of the chitosan treated wool was proposed. When treated with chitosan, the polymer sheath spread on the surface of the fibers acted as a predominant dyeing site in very short dyeing times, thus interacting with the dye and in later stages imparting the dye to the wool fiber.

AB  - The relation between shrink-resistance properties and surface changes (wettability, atomic chemical composition and topographical or morphological) induced by low-temperature plasmas (LTPs) has been studied in depth. For this purpose, plasma treatments with air, nitrogen and water vapor were carried out. Different surface techniques, such as contact angle measurement on single fiber, XPS analysis, SEM observations and Herbig sac formation, have been used. Also, the free radical formation was studied by EPR spectroscopy. It has been demonstrated that the plasma gas can be contaminated with water coming from the wool or the walls of reactor chamber. The fatty acid monolayer present on the outermost part of the fiber surface is progressively removed with increasing treatment time, but at short treatment time the oxidation of hydrocarbon chains prevails over its removal. The free radical formation depends on the treatment time and the plasma gas used. The shrinkage phenomenon of wool fabrics is found to be related also to the outermost surface chemical composition of the fiber.

AB  - The effect of water vapour plasma treatment on the shrinkage behaviour and chemical properties of the surface of keratin fibres was studied. The wettability and shrink resistance of wool were improved even at low plasma treatment times. The values of the advancing contact angles of keratin fibres treated with plasma provide evidence of the formation of hydrophilic groups in the wool surface. Analysis by XPS reveals that oxidation of the fatty acid monolayer (F-layer) prevails over its removal in the early stages of plasma treatment. The increase in treatment time results in a progressive removal of the F-layer.

Shrink resistance was attained at the machine-washable level without excessive damage to the fiber. XPS analysis revealed the partial oxidation of hydrocarbon chains of the F-layer and the formation of cysteic acid residues at the wool surface after plasma treatment. After subsequent enzymatic treatment, the F-layer was completely removed and the content of cysteic acid significantly decreased.

AB  - The influence of enzyme concentration and treatment time on certain wool properties has been studied according to the Box-Hunter experimental design in order to better understand the wool modification caused by two different enzymatic multi-purpose formulations (enzyme A and enzyme B). It is observed that enzyme concentration and treatment time exert an influence on wool whiteness, shrink resistance, weight loss and urea bisulphite solubility. The enzyme concentration has a decisive influence on wool modification when enzyme A is applied, and on the treatment time when enzyme B is applied. Tensile strength properties and SEMs suggest that enzyme B can attack the non-keratinic parts of wool fibre structure. No significant degradation of cortical or even cuticular cells is observed after enzyme A treatment. Accordingly, enzyme A could be applied all over the experimental zone whereas in the case of enzyme B, the enzyme concentration over 5% and treatment time over 60 min should be avoided. FTIR/ATR analysis confirms that there is no significant change in the redox state of cystine disulphide bonds at the wool surface after the enzyme treatment.

AB  - Incorporating an enzyme in the alkaline peroxide treatment bath enhances wool wettability and the effectiveness of subsequently applied chitosan biopolymer. Wool whiteness is also significantly enhanced. Wool knitted fabric thus treated is shrink resistant at the machine-washable level, which is one of the most important end-user demands. The formation of ionic bonds between the new sulphonic groups generated on the wool fiber surface and chitosan contribute to the shrink resistance of H2O2 + enzyme/chitosan treated wool. As a result of excessive increases in enzyme concentration in the peroxide bath, the wool surface cysteic acid content decreases, thus diminishing both the efficiency of post-applied chitosan solution and the shrink resistance.

AB  - Low temperature plasma treatments of wool modify only the cuticle surface of the fibers, improving their surface wettability, dyeability, fiber cohesion, and shrink resistance. The shrink-resist properties obtained with plasma treatment do not impart a machine-washable finish, which is an important end-user demand. However, the shrink resistance of air plasma treated wool is suitably enhanced by a subsequent biopolymer chitosan application. Using a qualitative colorimetric method, chitosan adsorption is shown to increase after treatment with air plasma. SEM observations yield information about the etching effect and chitosan adsorption. Given that both kinds of treatments, air plasma and chitosan, are environmentally acceptable, a new ecological shrink-proofing process is proposed.
