TransmittanceLa transmittance, en général, est le rapport caractérisant la transmission d'une grandeur dans un système. Elle se calcule par le rapport entre la grandeur en entrée et en sortie.
En optique, la transmittance d'un matériau ou d'un filtre est la fraction du flux lumineux le traversant. Elle est également nommée facteur de transmission mais aussi transparence dans le domaine de la photographie.Index. décimale : 668.5 Parfums et cosmétiques Résumé : Omyaskin® is a COSMOS and NaTrue certified high purity mineral ingredient for colour cosmetics and skin care. The particles have a lamellar surface, enabling sebum absorption, a mattifying effect and fast drying time. This innovative structured mineral significantly improves skin texture ; its highly efficacious smoothening effect becomes evident after only 15 minutes and lasts for at least four hours. The percentage addition to a skin care or colour cosmetics formulation varies between 1 and 10%, depending on final application and desired effect, and it can also be used as a viscosity controlling agent, due to its high absorption power.

Souplesse (mécanique)Index. décimale : 668.4 Plastiques, vinyles Résumé : The aim of this work is the analysis of the suitability of cardanol derivatives as primary plasticizer for polyvinyl chloride (PVC). Cardanol derived plasticizers (CDP) were obtained by acetylation of cardanol, followed by epoxidation of the side chain double bonds. The developed procedures allowed to achieve high yields of acetylated cardanol, whereas plasticizers characterized by different yields of epoxidation were obtained, according to the used synthesis procedure. Rheological analysis was used in order to study the gelation process of PVC plastisols with CDP. A comparison of commercial phthalate and natural derived plasticizers showed that the CDP are characterized by adequate gelation properties, involving a complete absorption of the plasticizers at relatively low temperatures. The gelation properties showed a strong dependence on the yield of the epoxidation. In particular, lower gelation temperatures, higher plasticizer absorption and faster gelation were observed for higher epoxy content in the plasticizer. Finally, ageing tests were performed on soft PVC produced by the CDP. The weight loss of soft PVC with CDP is comparable to that of commercial plasticizers, particularly at high yields of epoxidation.

ViscosimétrieIndex. décimale : 667.9 Revêtements et enduits Résumé : In previous studies on the drying performance of oleoresinous and solvent-based offset lithographic printing inks, a test was devised to determine the rate of absorption of drops of vegetable oils and solvents deposited on the surface of a paper substrate. The influence of viscosity on the rate of horizontal capillary absorption indicated a potential use of the absorption data to predict viscosity in the oxidative polymerization of polyunsaturated vegetable oils. Volumes as low as 1.0 mL could be used in thermal oxidative polymerization studies and tested by the Drop Deposition method. The stain radii R s of absorbed drops of the oil, e.g., on blotting paper or filter paper substrates, follow a linear relationship with the square root of time and the slopes m of the graphs are converted to dynamic viscosity in dPa.s units using a modified form of the Lucas Washburn equation from which m a. The study has implications for assessing the stability of vegetable oils used in frying operations. The test method may also be used in the study of room temperature oxidative polymerization of polyunsaturated vegetable oils to evaluate drier catalysts used in surface coatings.

Thé vert et constituantsIndex. décimale : 667.3 Teinture et impression des tissus Résumé : True colour measurements of wastewater samples, in terms of American Dye Manufacturers' Institute values, were used to evaluate the effectiveness of decolourisation of textile wastewater using spent green tea leaf powder waste. Raw wastewater samples with a true colour of 868 ADMI were used in the batch adsorption experiments. Results revealed that the true colour removal efficiency of the raw textile wastewater was high in acidic solution and at high temperature, indicating an endothermic nature of the system. The major functional groups of the green tea leaf powder waste involved in adsorption were identified by Fourier Transform-infrared spectroscopy analysis. Adsorption kinetic data were modelled using the modified Freundlich and intraparticle diffusion kinetics equations. Fitting results of the Langmuir adsorption isotherm showed that the adsorption capacity of the green tea leaf powder waste was 775 ADMI g−1, which is higher than that of powder activated carbon (526 ADMI g−1). The low activation energy values (13.9 kJ mol−1) suggested that adsorption was governed by a diffusion process and the reaction involved a physisorption mechanism. From the perspectives of waste utilisation, remarkable colour adsorption capacity and inexpensive and abundant availability, green tea leaf waste is an attractive alternative for decolourisaton of textile wastewater. Because high temperature favours colour removal, green tea leaf powder can be directly applied in raw textile wastewater treatment.

Calotropis gigantea
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).

KapokLe kapok, en malais kapuk, est une fibre végétale que l'on tire de fruits de plusieurs arbres de la famille des Bombacaceae. On utilise plus particulièrement ceux de Ceiba pentandra, le kapokier (aussi appelé « fromager »), un grand arbre des zones tropicales, originaire de Java. Ceux de Bombax ceiba, un autre fromager, peuvent également être employés.
Cette fibre très légère a pour caractéristique son imperméabilité et son imputrescibilité. Elle est constituée par les poils fins et soyeux recouvrant les graines.

Surfaces -- AnalyseIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Calotropis gigantea, kapok and cotton fibres are all natural cellulose fibres, but the first of these is rarely used in textile fabrics. In this study, the structure and chemical composition of these three kinds of fibre were studied, and the dyeing properties of fabrics made from each of them were compared. The purpose of this was to provide a theory basis for the application of C. gigantea fibre in the textile industry. The surface morphology and cross-section of C. gigantea fibre in comparison with kapok and cotton were studied by scanning electron microscopy. Their fibrous structures were analysed by Fourier Transform-infrared spectroscopy and X-ray diffraction. The mechanical properties and water absorption capabilities were also measured and compared. Both C. gigantea fibre and kapok fibre exhibit a high degree of hollowness (80–90%), and no natural twist exists; there is a certain amount of lignin and hemicellulose in C. gigantea fibres; the crystallinity of C. gigantea fibres is 42.54%, and its crystallinity orientation index is 85.40%. C. gigantea fibre has the lowest tenacity but has the highest water content of the three kinds of fibre. The results of dyeing tests show that C. gigantea fabric has the lowest dye uptake and dye fixation.
