Teinture -- Fibres textiles synthétiquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Thirteen dyestuffs of four chemical classes (quinophthalone, anthraquinone, isothiazole-fused anthrone and pyridone azo) were applied for the dyeing of unmodified polypropylene fibres in supercritical carbon dioxide. From these 13 dyestuffs, three dyestuffs that have a pure yellow hue and good dyeability for polypropylene fibres were found. The results of a dyeability test using the 13 dyestuffs suggested that the affinity for polypropylene fibres requires, in the structural character of the dyestuff molecule, not only extreme hydrophobicity but also high aliphaticity. The isothiazole-fused anthrone nonanamide dyestuff and two types of N-butyl substituted pyridone azo dyestuffs were examined for build-up and colour fastness properties. The light fastness of the dyed fabric was not so good. The ratings of fastness to washing, perspiration and rubbing ranged from excellent to fairly good with the increase of the depth of shade. From the relationship between the build-up curve and the colour fastness, it was found that the dyestuff of the isothiazole-fused anthrone nonanamide is suitable for polypropylene dyeing in a pale or medium shade, and that the two types of N-butyl substituted pyridone azo dyestuffs are suitable in a deep shade.

Teinture -- Fibres textiles synthétiquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : A series of 1,4-bis(alkylamino)anthraquinone dyestuffs were applied for supercritical fluid dyeing of unmodified polypropylene fabric, which is known to be difficult to dye in a conventional aqueous system. A marked tendency was shown that the dyeability improved as the carbon number of alkyl substituents on the anthraquinone chromophore increased. By evaluating the build-up curves of the dyestuff, it was found that the carbon number of optimum alkyl chain length for 1,4-bis(alkylamino)anthraquinone was 8–12. From the relationship between the build-up curve and the colour fastness, it was concluded that the upper limit of dyeing depth for good colour fastness was 40 mmol/kg of fibre.

Traîtements de surfaceIndex. décimale : 667.3 Teinture et impression des tissus Résumé : The effect of hydrophilicity and the charge of the fibre surface upon the formation of colloidal crystals on the fibre was investigated. Surface‐modified polyester fibre was prepared either by oxygen plasma treatment or with a sol‐gel method using 3‐aminopropyltriethoxysilane (APS). The surface‐modified polyester fibre was dip‐coated with 20 wt.% water suspension of uniform‐sized silica particles with a diameter of 300 nm and then it was dried. Hexagonal and square arrangements were observed for the particles deposited on the fibre surface by scanning electron microscopy (SEM). The crystallinity of deposited particles was estimated with the number ratio of arranged particles to all particles in the SEM image. On the plasma‐treated fibre, the crystallinity of deposited particles was 82% and the ratio of hexagonal arrangement to square arrangement was 3:1. On the APS‐treated fibre, crystallinity was 56% and the ratio was 1:8. The fibre‐fabricated colloidal crystal exhibited red colour on its surface and it had a peak wavelength of 637 nm in the reflection spectrum. Note de contenu : - Materials
