Colour dependency of textile samples on the surface texture / Saeideh Gorji Kandi in COLORATION TECHNOLOGY, Vol. 124, N° 6 (2008)  

[article]  inCOLORATION TECHNOLOGY > Vol. 124, N° 6 (2008) . - p.348-354 Titre : Colour dependency of textile samples on the surface texture Type de document : texte imprimé Auteurs : Saeideh Gorji Kandi, Auteur ; Mohammad Rahmati, Auteur ; Mohammad Amani Tehran, Auteur Année de publication : 2009 Article en page(s) : p.348-354 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : In this paper, the perceptual and instrumental effects of texture on colour is investigated, using 63 textile samples, in nine colour centres and seven texture structures. The effectiveness of texture is evaluated by assessing colour differences between six texture samples and a standard texture in each colour group. Experimental results show that the sample texture has a significant effect on the measured and perceived colour and its influence depends on the colour centre of the sample. The magnitude of texture effect is more dependent on the texture type than on its coarseness. A new term to evaluate texture difference of a pair of textile samples was defined using a Gabor filter (Gabor texture difference). The visual colour changes gave a good correlation with Gabor texture difference values; however, the colour of the samples affected this correlation. So the colour change, as a result of texture differences, depends on two independent variables consisting of the Gabor texture difference and the colour centre of samples.

Syntheses of polymeric dispersants for pigmented ink-jet inks / Chun Yoon in COLORATION TECHNOLOGY, Vol. 124, N° 6 (2008)  

[article]  inCOLORATION TECHNOLOGY > Vol. 124, N° 6 (2008) . - p. 355-363 Titre : Syntheses of polymeric dispersants for pigmented ink-jet inks Type de document : texte imprimé Auteurs : Chun Yoon, Auteur ; Jae-Hong Choi, Auteur Année de publication : 2009 Article en page(s) : p. 355-363 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : Drop-on-demand ink-jet inks made from dyes usually show poor light fastness and poor water fastness. Therefore, many researchers have introduced pigments into ink-jet inks to overcome the defects of dye-based ink. Pigmented ink needs sophisticated technology which disperses the pigments stably in low viscosity. Thus, adequate dispersants are essential to achieve stable dispersions of pigments for ink-jet inks. This study describes syntheses of dispersants, properties of formulations and comparisons of performance with an existing ink to assess their suitability for commercial application.

Novel azo dyes derived from phthalimide. Part 2 / Jae-Hong Choi in COLORATION TECHNOLOGY, Vol. 124, N° 6 (2008)  

[article]  inCOLORATION TECHNOLOGY > Vol. 124, N° 6 (2008) . - p. 364-369 Titre : Novel azo dyes derived from phthalimide. Part 2 : Dyeing properties and colour fastness on polyester fibres Type de document : texte imprimé Auteurs : Jae-Hong Choi, Auteur ; Jong-yun Choi, Auteur ; Hyun-young Lee, Auteur ; Andrew D. Towns, Auteur ; Chun Yoon, Auteur Année de publication : 2009 Article en page(s) : p. 364-369 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : The coloration and fastness properties of 18 carbocyclic monoazo disperse dyes bearing a phthalimide ring fused to the aromatic ring of their diazo components have been investigated. In each case, the phthalimidyl nitrogen atom was substituted with either a butyl, sec-butyl or isopropyl group, while the adjoined phenyl ring bore a substitution pattern typical of commercial colorants. Dye uptake and build-up onto both conventional and microfibre polyester through exhaustion dyeing were examined: while the expected tendency of greater exhaustion on microfibre was noted, there were few clear trends with respect to dye structure. The nature of the N-alkyl group made no consistent difference to dye uptake. Attempts to explain the observed percentage exhaustion values by mapping them to calculated partition coefficient or solubility parameter values were unsuccessful. Wash fastness tended to be best for blue dicyano-substituted derivatives, which may be as a result in part of these substituents promoting hydrolysis of the adjacent phthalimide ring to give more soluble phthalate species. In contrast, the dicyano dyes had relatively poor photostability compared with their unsubstituted analogues.

Fenton and photo-Fenton oxidation of a model mixture of dyes – overall kinetic analysis / Francesc Torrades in COLORATION TECHNOLOGY, Vol. 124, N° 6 (2008)  

[article]  inCOLORATION TECHNOLOGY > Vol. 124, N° 6 (2008) . - p. 370-374 Titre : Fenton and photo-Fenton oxidation of a model mixture of dyes – overall kinetic analysis Type de document : texte imprimé Auteurs : Francesc Torrades, Auteur ; José Antonio Garcia-Hortal, Auteur ; Lluis Nùnez, Auteur Année de publication : 2009 Article en page(s) : p. 370-374 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : The decolorisation and mineralisation of a model mixture of reactive dyes, under Fenton and photo-Fenton conditions, have been investigated. A kinetic study was performed and rate constants and half-life times determined from batch experimental data according to a pseudo-first-order degradation kinetic model. Moreover, the use of natural or artificial light, as well as the effect of temperature, was evaluated with the aim of finding the best Fenton process to promote the efficient degradation of the standard trichromatic system. The experimental results showed that the Fenton process run under solar light was the most effective. It is suggested that Fenton- and photo-Fenton-type reactions are viable techniques for the treatment of these types of dye mixtures, according to the high levels of colour, chemical oxygen demand and total organic carbon removal.

Effect of different softeners and sanforising treatment on pilling performance of polyester/viscose blended fabrics / Tanveer Hussain in COLORATION TECHNOLOGY, Vol. 124, N° 6 (2008)  

[article]  inCOLORATION TECHNOLOGY > Vol. 124, N° 6 (2008) . - p. 375-378 Titre : Effect of different softeners and sanforising treatment on pilling performance of polyester/viscose blended fabrics Type de document : texte imprimé Auteurs : Tanveer Hussain, Auteur ; Sohail Ahmed, Auteur ; Abdul Qayum, Auteur Année de publication : 2009 Article en page(s) : p. 375-378 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : An 80:20 polyester/viscose blended woven fabric was subjected to different softening and sanforising treatments. The effect of different softeners and sanforising treatments on the pilling propensity of the fabric was investigated. It was found that, while some types of softeners had no effect on pilling, the others may result in extreme deterioration of the pilling performance of polyester/viscose blended fabrics. It was further found that, in all cases, sanforising after softening adversely affects the fabric pilling performance.

[article]  inCOLORATION TECHNOLOGY > Vol. 124, N° 6 (2008) . - p. 379-384 Titre : 3-Hydroxy-2-[1'-phenyl-3'-(p-chlorophenyl)-4'-pyrazolyl]-4-oxo-4H-1-benzopyran as a spectrophotometric reagent for trace determination of tungsten(vi) Type de document : texte imprimé Auteurs : R. Agnihotri, Auteur ; R. Kamal, Auteur ; N. Agnihotri, Auteur ; J. R. Mehta, Auteur Année de publication : 2009 Article en page(s) : p. 379-384 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : 3-Hydroxy-2-[1'-phenyl-3'-(p-chlorophenyl)-4'-pyrazolyl]-4-oxo-4H-1-benzopyran solution in acetone forms a yellow-coloured complex with tungsten(vi) in perchloric acid medium which is extractable into chloroform after equilibration. In this study, tests were carried out on this compound and it was found to be quite stable and to obey Beer's law. Interactions with various ions were studied and the molar absorptivity, Sandell's sensitivity and relative standard deviation were also investigated. Job's method, the mole ratio method and the equilibrium-shift method were also used. The ratio of metal to ligand was measured using a method that was simpler, more accurate, sensitive, rapid and selective as compared with existing methods. This method is applicable to the analysis of various samples of varied composition.
