Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : The introduction of bulky aryl residues into wool fibres not only enhances their disperse dyeability but also improves their settability, shrink resistance and imparts easy-care properties. It would be highly desirable for colourists to achieve such effects when dyeing or printing wool from an aqueous solution as wool/polyester blend fabrics could be dyed and printed with the same dye; furthermore, in the case of an all-wool fabric pretreated with such arylating systems, following dyeing or printing with disperse dyes, dye fixation can be achieved by dry heat procedures. A water-soluble, fibre-reactive arylating agent, sodium benzoyl thiosulphate, was therefore synthesised, characterised and its stability to hydrolysis in aqueous media was examined.

Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : Sodium benzoyl thiosulphate was applied to wool fabric from aqueous solutions in order to covalently bind benzoyl groups to the fibre and thus impart disperse dye substantivity to the modified wool. The modified wool fabric was dyed with a selected model disperse dye, CI Disperse Blue 56, and the wash fastness properties of the dyeings assessed.

Design and application of a multifunctional reactive dye capable of high fixation efficiency on cellulose / K. F. Morris in COLORATION TECHNOLOGY, Vol. 124, N° 3 (2008)  

[article]  inCOLORATION TECHNOLOGY > Vol. 124, N° 3 (2008) . - p. 186-194 Titre : Design and application of a multifunctional reactive dye capable of high fixation efficiency on cellulose Type de document : texte imprimé Auteurs : K. F. Morris, Auteur ; David M. Lewis, Auteur ; Peter J. Broadbent, Auteur Année de publication : 2009 Article en page(s) : p. 186-194 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : A polyfunctional reactive dye containing two dichloro-s-triazine residues linked through aliphatic amino groups via a third triazine system to the chromophoric residue has been prepared. The dye was synthesised stepwise from a specially synthesised 2,4-dichloro-s-triazine dyes. The first step is the reaction of both carbon–chlorine sites in the 'parent' dye with 2 mol ethylenediamine under selected conditions of pH and temperature; these conditions ensure that only one of the amino groups in the ethylenediamine will react to give the bis-2,4-aminoethyleneaminotriazine dye. The second step is the condensation of 2 mol cyanuric chloride with the two pendant primary amino groups. The alkylamino-linked dichloro-s-triazine dyes show very different dyeing properties when compared with those shown by the parent dichloro-s-triazine dye, which has the reactive group linked directly into the aromatic chromophore; in particular, the new dyes have high fixation efficiencies when dyed on cotton at 50 °C and the dye–fibre bond stability to boiling acidic conditions is very good.

Development of a novel three-dimensional printing technology for the application of "raised" surface features / David M. Lewis in COLORATION TECHNOLOGY, Vol. 137, N° 5 (10/2021)  

[article]  inCOLORATION TECHNOLOGY > Vol. 137, N° 5 (10/2021) . - p. 468-474 Titre : Development of a novel three-dimensional printing technology for the application of "raised" surface features Type de document : texte imprimé Auteurs : David M. Lewis, Auteur ; Peter J. Broadbent, Auteur ; Muriel Rigout, Auteur ; Chris M. Carr, Auteur ; Fearne Johnson, Auteur Année de publication : 2021 Article en page(s) : p. 468-474 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Encre d'imprimerie Impression jet d'encre Impression tridimensionnelle Index. décimale : 667.4 Encres Résumé : A simple procedure to ink-jet print raised images using two water-soluble inorganic inks is reported and it has the potential to be utilised in domestic and commercial environments. The advantages of such a procedure lies in the ability to print moulded objects, Braille type and to engineer special gonio-specific effects that may have value in the security printing area. The study focuses on printing gypsum through the ready precipitation of calcium sulphate dihydrate by co-jetting calcium chloride and ammonium sulphate solutions. The results in this preliminary study are encouraging and offer a potential method for durable surface structuring of material surfaces with haptic and visual effects for both the blind and the sighted.

Developments in the chemistry of reactive dyes and their application processes / David M. Lewis in COLORATION TECHNOLOGY, Vol. 130, N° 6 (12/2014)

Lewis, Auteur Année de publication : 2014 Article en page(s) : p. 382-412 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Colorants réactifs Fibres cellulosiques Fibres textiles Fibres textiles synthétiques Laine Polyamide 66 Polyamides Un polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine. Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères. Soie et constituants Teinture -- Fibres textiles Index. décimale : 667.3 Teinture et impression des tissus Résumé : This review describes the immense impact of reactive dyes on the textile industry. Their use on cellulosic fibres is especially important, but their growing popularity on polyamide substrates is notable. Detailed information is given about developments both in the chemistry of reactive systems and in the chemical technology involved in their application to a variety of fibre types. It is also pointed out that further research is necessary to improve dye–fibre fixation efficiency, especially when dyeing full shades on cellulosic fibres. This work is necessary to address the current environmental problem of colour in dyehouse effluent. The potential solutions reviewed include multifunctional reactive dyes, cationic reactive dyes, and cellulose fibre modification.
