ThermogravimétrieIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Leather is a material used for various purposes including upholstery in airplanes, ships, automobiles and furniture. Leather requires good fire resistance properties for use in upholstery due to the possibilities of exposure to fire. Here, we report a method to produce fire retardant leather using organic nanoclay and ammonium dihydrogen phosphate as flame retardant additives through surface coating. Treated leathers were characterized using vertical flammability test, thermogravimetric analysis, scanning electron microscopic analysis, mechanical and hand and visual evaluation. Treated leathers left higher residues at 700oC than the control leather indicating their lower thermal decomposition potential. Further, we demonstrated that the ignition time of treated leathers is increased by more than 5 sec and treated leathers show negligible flame time after fire source was removed. The physical and organoleptic evaluations of treated leathers as well as other results suggest that a combination of organic nanoclay and inorganic phosphate provides fire retardant leathers for upholstery leather applications with acceptable strength and bulk properties.

Polymerizations were performed in emulsions with aerosol EF-800 surfactant; remarkable colloidal stability of the copolymer latexes was measured in fresh and aged samples. The effects on film formation, tensile properties, permeability to water vapor, and oxygen were evaluated by varying the TMI concentrations (from 0 to 6 wt%). The obtained latexes were used as binder to prepare water-based coatings, which were applied on steel specimens; hydrolysis of TMI acts as a self-crosslinked promoter once the film was applied. Adhesion tests, scratch hardness, and gloss properties were evaluated.

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).

Taille des particulesIndex. décimale : 667.9 Revêtements et enduits Résumé : In this paper, novel core–shell polymers comprising styrene (St) and butyl acrylate (BA) in both core and shell layers of the polymer particles have been synthesized and employed in pigment printing pastes which were applied on 100% cotton and 65% cotton/35% polyester (PET) fabrics. The aim was to reduce the NMA content and the formation of free formaldehyde from pigment printing pastes by employing newly synthesized core-/shell-type polymers. After five washing cycles, the synthesized core-/shell-type polymer including 1% NMA in the core and 1% NMA in the shell with T g values +30°C and −20°C, respectively, with lowest total NMA content (1.03%) yielded the best result and showed closest ΔE values to the commercially available polymer including 4% NMA. Dry and wet rubbing fastness results showed no significant changes in the absence of NMA when compared with NMA containing samples. The penetration degree of the pigment pastes of the corresponding polymers was relatively higher on 100% cotton fabric for both red- and blue-colored pigments. A negligible decrease in color strength has been observed for all polymers when colored in red.

Teinture -- Fibres textiles synthétiquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Disperse dyes containing a ?-sulphatoethylsulphonyl group have temporary solubility and can be applied for dispersant-free dyeing of hydrophobic fibre. Six novel temporarily solubilised azo disperse dyes having a ?-sulphatoethylsulphonyl group in their structures were synthesised, and their dyeing properties on polyester were investigated. As a dye intermediate, a diazo component having dibromo groups was prepared, and 4-diethylamino-4?-(2-sulphatoethylsulphonyl-4,6-dibromo)azobenzene dyes were prepared by a diazo-coupling reaction. Then, the dyes containing dicyano groups were prepared by cyanation of corresponding dyes with dibromo groups. The absorption maxima of the dyes were affected by the substituents in the diazo and coupling component rings and varied from 434 to 616 nm in dimethylformamide. Polyethylene terephthalate woven fabric could be dyed with the synthesised temporarily solubilised dyes without using any dispersants. Dyebath pH affected the K/S value at maximum absorption as well as percentage exhaustion on polyethylene terephthalate fabric, and the optimum pH was 5. The dyes gave brownish orange, red, purple, and greenish blue hues on polyethylene terephthalate fabrics, and colour build-up was good. Wash fastness was good to excellent, rubbing fastness was moderate to excellent, and light fastness was poor to moderate.

Revêtements poudre:Peinture poudreIndex. décimale : 667.9 Revêtements et enduits Résumé : Powder coating systems have been developed to provide scratch modified and super durable coatings that maintain gloss levels following stringent testing.
The definition of scratch resistance according to DIN describes the resistance of paint films under defined conditions towards point-like, linear or two-dimensional loads. Checking the quality of the adhesion of paints is a special metrological challenge, that's why a large number of specific procedures exist in the audit practice. To determine the scratch resistance, the standards DIN EN ISO 1518 parts 1 & 2 and DIN EN ISO 12137 are particularly suitable.Note de contenu : - MATERIAL-RELATED PHYSICAL ASPECTS OF SCRATCH RESISTANCE : Sratch resistance
