Teinture -- Fibres textiles synthétiquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : The efficiency of ozone treatment for the clearing of disperse dyed polyethylene terephthalate fibres has been examined. The ozone treatment for the clearing of the dyed samples was performed by blowing the ozone gas from the ozone generator on to the wet fabric samples. The results indicated that 3- and 5-min ozonation times were appropriate to achieve comparable wash fastness results with conventional reduction clearing without significant colour differences (?E* value) for the samples dyed with CI Disperse Yellow 23 and CI Disperse Blue 79, respectively; however, the ozonation time had to be increased to 15 min for CI Disperse Red 82. Tensile strength tests and scanning electron microscopy analysis indicated that the ozone treatment did not cause any severe damage to the fabrics. Ozone treatment for the afterclearing of disperse dyed polyester fabric can lead to energy and time savings and environmental load reduction when compared with conventional reduction clearing. This study tested a new method of ozone application for clearing of disperse dyed polyester by blowing ozone directly on to the fabric samples. This new method of application has the advantage of being readily adoptable for continuous treatment lines and lower water consumption.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : A large number of studies have been devoted to the development of chromic textile materials because of their wide applicability as sensor systems. More recently, pH-sensitive chromic textiles have also been investigated to a considerable extent, as the pH value is an important parameter in various circumstances. This review therefore elaborates on pH-sensitive textile materials. The outcome of this review process demonstrates that halochromic dyes can be successfully incorporated into textile materials, leading to flexible sensors. Various textile materials and different application methods have both been shown to be effective. Yet the textile material in which the pH-sensitive agent is present affects its halochromic behaviour and this factor should thus always be considered. Finally, this review establishes the major potential of pH-sensitive textile materials. Note de contenu : - The theory and development of pH-sensitive dyes

Structure cristalline (solide)Index. décimale : 667.3 Teinture et impression des tissus Résumé : The synthesis, crystal structure analysis and characterisation of a monoazo dye, CI Disperse Orange 61, are reported. The dye crystallised in the triclinic system, space group P-1 with a = 8.859(2), b = 9.899(2), c = 11.417(3)Å, α = 78.51(4)°, β = 70.37(3)°, γ = 80.46(4)°, V = 918.8(4)Å3 and Z = 2. There is only one molecule in the asymmetric unit. The two phenyl rings are oriented at a dihedral angle of 57.87(20)°. In the crystal structure, intermolecular C–H…N hydrogen bonds link the molecules into centrosymmetric dimers, forming R22(30) ring motifs, in which they may be effective in the stabilisation of the structure. The π…π stacking (interactions) between the phenyl rings may further stabilise the structure, with a centroid–centroid distance of 3.741(4)Å.

CotonLe coton est une fibre végétale qui entoure les graines des cotonniers "véritables"(Gossypium sp.), un arbuste de la famille des Malvacées. Cette fibre est généralement transformée en fil qui est tissé pour fabriquer des tissus. Le coton est la plus importante des fibres naturelles produites dans le monde. Depuis le XIXe siècle, il constitue, grâce aux progrès de l'industrialisation et de l'agronomie, la première fibre textile du monde (près de la moitié de la consommation mondiale de fibres textiles).

TriclosanLe triclosan est un composé organochloré, proche des chlorophénols, qui possède des propriétés antifongiques et antibactériennes à large spectre. Il est aussi appelé 5-chloro-2-(2,4-dichlorophénoxy)phénol.Index. décimale : 667.3 Teinture et impression des tissus Résumé : One of the processes for the application of functional compounds that alter textile properties is encapsulation. In our research, a microencapsulated biocide was used to produce an antimicrobial textile product. Melamine–formaldehyde polymer wall microcapsules with a triclosan core were applied to a cotton fabric by screen printing. Printed samples were dried and cured. The fabric hand properties of washed and unwashed samples were tested and the antibacterial activity against Staphylococcus aureus and Escherichia coli was evaluated. The quantity of free formaldehyde on the printed and washed samples was monitored for 2 months. The results show that microcapsules with triclosan can be successfully applied to a cotton fabric by printing, where they provide good antibacterial protection without substantially changing the fabric properties. The quantity of formaldehyde on the unwashed samples is high and it changes with time; however, it significantly decreases with washing.

Teinture -- Fibres textiles synthétiquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Polyethylene terephthalate and elastane fabrics were treated with azo disperse dyes in the same dyebath at 130 °C for 0, 30 and 60 min and then reduction cleared. The dyes adsorbed on each fabric were extracted using monochlorobenzene, in order to determine the amount of disperse dye in each of the polyethylene terephthalate and elastane fabrics, as the dyeing time was increased. It was observed that the amount of dye on the polyethylene terephthalate increased, while that on the elastane decreased, as the time at 130 °C increased from 0 to 60 min. After reduction clearing, the partition ratio of disperse dyes between the polyethylene terephthalate and the elastane increased. The dyed polyethylene terephthalate/elastane blend indicated that those dyes, which exhibited high partition ratios (polyethylene terephthalate:elastane), exhibited correspondingly higher wet fastness properties.

Rouge carthamineIndex. décimale : 667.3 Teinture et impression des tissus Résumé : While the contribution of ultraviolet absorbers to synthetic dyes has been investigated by several workers, there have been few studies pertaining to the use of functional ultraviolet absorbers as a means of improving the light fastness of natural dyes. In this paper, numerous potential ultraviolet absorbers were prepared to prolong the life of natural dye carthamin. The effects of these compounds in reducing photofading were examined on a polymer substrate. The use of commercial ultraviolet absorbers was not necessarily useful in improving the light fastness of the colour. However, benzophenone-type ultraviolet absorbers containing a built-in ultraviolet absorber moiety markedly retarded the photofading rate. It is proposed that 2,2′,4,4′-tetrahydroxy-5-methylbenzotriazolylbenzophenone and its derivatives may be used as effective stabilisers in the fading of natural dyes.

Hydroxyde de sodiumL'hydroxyde de sodium, appelé également soude caustique7, est un corps chimique composé minéral de formule chimique NaOH, qui est à température ambiante un solide ionique. Fusible vers 318 °C, il se présente généralement sous forme de pastilles, de paillettes ou de billes blanches ou d'aspect translucide, corrosives et très hygroscopiques. Il est très soluble dans l'eau et légèrement soluble dans l'éthanol.
La solution d'hydroxyde de sodium, souvent appelée soude, est une solution aqueuse transparente. Concentrée, elle est corrosive et souvent appelée lessive de soude.
Les propriétés chimiques de l'hydroxyde de sodium sont surtout liées à l'ion hydroxyde HO- qui est une base forte. En outre, l'hydroxyde de sodium réagit avec le dioxyde de carbone (CO2) de l'air et se carbonate.
La solubilité de la soude caustique dans l'eau augmente avec la température, à pression constante ou ambiante.

Teinture -- Fibres textiles synthétiquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Various synthetic fibres, namely, polyethylene terephthalate, nylon 6.6, acrylic and spandex fabrics, were dyed with indigo blue using an exhaust technique. The factors studied were sodium dithionite and sodium hydroxide concentrations, liquor/material ratio, dyeing temperatures and process times. The pH levels of the dyebaths were achieved by controlling the ratios of sodium dithionite and sodium hydroxide concentrations. Dyebath analysis at the end of dyeing showed that, in different pH regions, different forms of the indigo existed and each one exhibited different degrees of substantivity for synthetic fibres. The nonionic form exhibited substantivity for all the synthetic fibres, while the mono-sodium phenolate form showed substantivity only in the acidic range. Synthetic fibres could best be dyed in the pH range of 5.5–6. Reflections spectra showed that indigo in synthetic fibres and when dissolved in dimethyl formamide absorbed maximally at 610 nm, while in cotton indigo absorbed at 660 nm. The fastness properties were measured and the results showed that washing and rubbing were good, while light and sublimation were moderate to poor.

Polylactique, AcideL'acide polylactique (anglais : polylactic acid, abrégé en PLA) est un polymère entièrement biodégradable utilisé dans l'alimentation pour l'emballage des œufs et plus récemment pour remplacer les sacs et cabas en plastiques jusqu'ici distribués dans les commerces. Il est utilisé également en chirurgie où les sutures sont réalisées avec des polymères biodégradables qui sont décomposés par réaction avec l’eau ou sous l’action d’enzymes. Il est également utilisé pour les nouveaux essais de stent biodégradable.
Le PLA peut-être obtenu à partir d'amidon de maïs, ce qui en fait la première alternative naturelle au polyéthylène (le terme de bioplastique est utilisé). En effet, l'acide polylactique est un produit résultant de la fermentation des sucres ou de l'amidon sous l'effet de bactéries synthétisant l'acide lactique. Dans un second temps, l'acide lactique est polymérisé par un nouveau procédé de fermentation, pour devenir de l'acide polylactique.
Ce procédé conduit à des polymères avec des masses molaires relativement basses. Afin de produire un acide polylactique avec des masses molaires plus élevées, l'acide polylactique produit par condensation de l'acide lactique est dépolymérisé, produisant du lactide, qui est à son tour polymérisé par ouverture de cycle.
Le PLA est donc l’un de ces polymères, dans lequel les longues molécules filiformes sont construites par la réaction d’un groupement acide et d’une molécule d’acide lactique sur le groupement hydroxyle d’une autre pour donner une jonction ester. Dans le corps, la réaction se fait en sens inverse et l’acide lactique ainsi libéré est incorporé dans le processus métabolique normal. On obtient un polymère plus résistant en utilisant l'acide glycolique, soit seul, soit combiné à l’acide lactique.
Teinture -- Fibres textiles synthétiquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : 1-(4′-Alkylaminosulphurylphenyl)-3-methyl-5-pyrazolonyl azo–anthraquinone dyes were prepared in four steps from 1-aminoanthraquinone, as an approach to enhancing the exhaustion levels of disperse dyes on polylactide fibres. Their structures were confirmed from combustion analysis and mass spectrometry, infrared and proton nuclear magnetic resonance spectroscopy. Results from artificial intelligence-based molecular modelling studies showed that increasing alkyl chain length gave an increase in LogP, molecular volume and aplanar shape. Their application to polylactide fibres led to both good per cent exhaustion values and good light fastness ratings. It was also found that the nature of the alkyl chains attached to the phenyl ring had little influence on dye colour, but clearly influenced per cent exhaustion and wash fastness.

The investigations were carried out at pressures of 7.5–25.0 MPa, temperatures of 333.15–413.15 K and an equilibrium contact time of 120 min. As revealed from the experimental results, the solubility of the reactive disperse dye increased with pressure in different isotherms, and decreased with temperature. Furthermore, the experimental solubility data were correlated successfully with semi-empirical models – Chrastil and Del Valle–Aguilera equations, respectively – at various temperatures and pressures.

Teinture -- Fibres textiles
Textiles et tissusIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Light fastness tests conducted on several areas of a light-sensitive material may sometimes show inconsistent fading rates. These different fading behaviours suggest that colorants are not evenly distributed over the substrate surface or may be attributed to texture variations of the material. A mathematical model has been developed to help explain these discrepancies. Micro-fade testing, a relatively novel technique, has allowed microspectroscopic detection of variations in the initial colour parameters of a sample, permitting assessment of its diverging fading rates. The method has been applied to fading data of various light-sensitive materials resulting in more consistent fading patterns. It has been demonstrated that micro-fading curves obtained for the same material are related by a constant value, which is the ratio of adjusted values of time and ΔE*.

Their dyeing properties, fluorescent reflectance and colorimetric properties were explored. The novel fluorescent dyes existed in two forms of monocation and dication in solutions at low pH and high temperature. Overall, the influence of pH on colour depth and the maximum reflectance of dyed cationic dyeable polyester was extremely small. The adsorption mechanism of DHEASPBr-C2 and DHEASPBr-C8 on cationic dyeable polyester fibres was in good accord with the Langmuir type. Compared with DHEASPBr-C2, DHEASPBr-C8 exhibited comparatively faster adsorption rate, higher affinity and dye uptake, while its fluorescence shown by cationic dyeable polyester was slightly weak.

ViscoseIndex. décimale : 667.3 Teinture et impression des tissus Résumé : The aim of this study was to carry out triple dyeing of woven polyester/cationic dyeable polyester/viscose rayon blend fabrics with the required colour fastness and physical properties. The feel and final appearance of the fabric were achieved by partial removal of the viscose rayon moiety of the fabric through optimised causticisation treatments. The results of the triple dyeings obtained from laboratory and small-scale experiments were successfully scaled up in authentic processing equipment. The final product, which has a yarn-dyed effect, readily satisfied the requirements related to the colour fastness and physical properties. Note de contenu : - Materials
