UltrasonsIndex. décimale : 667.3 Teinture et impression des tissus Résumé : In the colouring processes of textile products, more environmentally friendly chemicals and finishing methods should be used instead of conventional ones that harm the environment every day, so that alternative realistic ways to protect nature, both academically and industrially, could be possible. Due to some inconveniences caused by synthetic dyes that are widely used today, in this study, ultrasonic dyeing of wool fabric with Hibiscus sabdariffa was carried out after environmental-friendly air vacuum plasma application which increased the absorption of the dyes into the textile material. According to the performance results, colour strengths of the wool fabrics were increased significantly. Surface morphology analysis was carried out and etching effects of air vacuum plasma treatment were clearly seen on the micrographs of the treated wool fabrics. An environmental-friendly green process was achieved through this study and it was concluded that vacuum air plasma treatment could be an alternative green-process as a pretreatment to increase the dye up-take of natural dyeing treatment. Moreover, in this study, a feed-forward neural network (FFNN) model was presented and used for predicting the dyeing properties (L, a, b and K/S) of samples. The experimental results showed that the presented model achieves the regression values greater than 0.9 for all dyeing properties. Consequently, it was considered that the proposed FFNN was successfully modelled and could be efficiently utilised for dyeing characteristics of wool fabrics dyed with natural dye extracted from Hibiscus sabdariffa.

This study presents a novel one-bath/two-stage exhaust finishing process to improve the oxidative wash fastness of CI Leuco Sulphur Black 1-dyed cotton fabric. The effect of the combined Tinofix ECO and Bayprotect Cl after-treatment was to impart better colour fastness to oxidative International Organisation for Standardisation (ISO) 105 CO9 washing of the dyed cotton compared with those dyed fabrics after-treated with Tinofix ECO alone. In addition, while the dyed fabrics rub and light fastness performances were unchanged by the after-treatments, some improvement in the tensile strength of the combined Tinofix ECO and Bayprotect Cl after-treated fabrics was observed.

Plasma à pression atmosphériqueUn plasma à pression atmosphérique (ou plasma à PA ou plasma froid) est le nom donné à une catégorie spéciale de plasma pour lequel la pression approche celle de l’atmosphère.
Le plasma à pression atmosphérique marque une nette différence avec le plasma basse et haute pression. En effet, contrairement à ces derniers aucune enceinte de traitement n'est nécessaire. Ce type de plasma peut donc être utilisé directement sur ligne de production, évitant ainsi l'utilisation de vide qui est extrêmement onéreuse.

Vêtements en cuirIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : In this study the effect of argon atmospheric pressure plasma on the finishing process of garment leathers was investigated. The argon atmospheric pressure plasma (APP) activation was applied to the garment leathers' surfaces for different treatment times (0, 3, 6 and 9 sec/cm2). After argon APP application, the garment leathers were produced by traditional finishing process. The surface properties of the treated leathers were characterised by scanning electron microscopy (SEM). The elemental and chemical composition of the leather surfaces was assessed by XPS (X-ray photoelectron spectroscopy) and FTIR (Fourier Transform Infrared Spectroscopy) analysis, respectively. The surface states of the leathers were evaluated by contact angle measurements and physical properties of the leathers such as tensile strength, elongation at break, double edge tear load, thickness, colour and rubbing fastness were examined. According to the obtained results, it was found that the hydrophilic property of the plasma treated garment leathers is increased. In the physical properties results, a slight increase in tensile strength, tear load and elongation at break were observed being in parallel with the increase in plasma duration. In addition, plasma modification improved the colour and rubbing fastness of the leather alter finishing. The best results were obtained for 9 seconds of argon plasma treatment. It was concluded that non-destructive modification of leather surface leading to better physical and fastness properties could be achieved by appropriate gas selection and sufficient application time.

Teinture -- Fibres textiles synthétiquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : The potential for laccase (EC 1.10.3.2) to be used within the area of textile coloration, specifically for the generation of decorative surface pattern design, remains relatively unexplored. The current study presents a novel process for the coloration of wool and nylon 6,6 fibres via laccase oxidation of aromatic compounds as an alternative to conventional dyeing methods. Emphasis was placed on producing a diverse colour palette, which was achieved through the investigation of three different aromatic compounds as laccase substrates : 1,4-dihydroxybenzene, 2,7-dihydroxynapthalene and 2,5-diaminobenzenesulphonic acid. Reaction processing parameters such as buffer systems and pH values, laccase and aromatic compounds concentration, and reaction times were investigated, all in the absence of additional chemical auxiliaries. Enzymatically dyed fabrics were tested against commercial standards, resulting in reasonably good colour fastness to wash. To demonstrate the coloration and design potential by laccase catalysation of aromatic compounds, specially constructed fabrics using a combination of undyed wool, nylon and polyester yarns were dyed using the one-step laccase-catalysed coloration process. The use of different fibre types and weave structures enabled simple colour variations to be produced. Shadow, reserve and contrasting effects were achieved with the laccase-catalysed dyeing process developed. Important advantages over conventional processing methods include the use of simpler and milder processing conditions that eliminate additional chemical use and reduce energy consumption.

VernisIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : In the present study the effect of TiO2-SiO2-GLYMO nanocomposite on surface properties of leather was investigated. The TiO2-SiO2-GLYMO composite was prepared through the sol-gel route from tetraethoxysilane (TEOS) and titanium n-butoxide (TBO). 3-glycidoxypropyltrimethoxysilane (GLYMO) was added as coupling agent to provide a stable bond between metal oxides and leather substrate. The prepared composite was applied by spraying on the top coat of leathers in finishing. The surface properties observed by scanning electron microscopy (SEM) showed an even and homogenous coating obtained on leather by application of the composite in the presence of lacquer. The chemical structure of composite films was examined via Fourier transform infrared (FTIR) and Si-O-Ti bond and opening of epoxy rings of GLYMO were revealed. The presence of Ti and Si in the composite treated leather samples was ascertained by inductively coupled plasma optic emission spectrometer (ICP-OES). The results of the physical and fastness tests indicated that the use of TiO2-SiO2-GLYMO nanocomposite improves some performance characteristics of leather such as finish adhesion, dry and wet rubbing fastness, colour fastness to light and UV light. The results are promising for the refinement of leather surface with the application of the nanocomposite in the finishing process.
