Fading of reactive dyes on cellulose under light and perspiration / Dehua Zhuang in COLORATION TECHNOLOGY, Vol. 123, N° 2 (2007)  

[article]  inCOLORATION TECHNOLOGY > Vol. 123, N° 2 (2007) . - p. 80-85 Titre : Fading of reactive dyes on cellulose under light and perspiration Type de document : texte imprimé Auteurs : Dehua Zhuang, Auteur ; Liyuan Zhang, Auteur ; Dawei Pan, Auteur ; He Jinxin, Auteur Année de publication : 2007 Article en page(s) : p. 80-85 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : The fading of nine reactive dyes on cotton fabrics under light and perspiration was investigated using the ATTS standard and many factors affecting the stability of these dyes were discussed, viz. exposure environment, chromophores of dyes, the pH value and components of the artificial perspiration. The experimental results show that reactive dyes exhibit lowest stability under simultaneous exposure to light, perspiration and oxygen in a wet state. Among all selected dyes, Cu-complex azo reactive dyes appear to be the most sensitive, whereas anthraquinone reactive dyes show the best stability. The pH value of perspiration may also greatly influence the fading of dyes by affecting the hydrolytic stability of dye–fibre bonding. Furthermore, the study on the contribution of artificial perspiration components discloses that some acidic components play major roles in the fading of the dyes and inorganic salts usually decelerate the fading extent.

Modification of silk with aminated polyepichlorohydrin to improve dyeability with reactive dyes / Xie Weiben in COLORATION TECHNOLOGY, Vol. 123, N° 2 (2007)  

[article]  inCOLORATION TECHNOLOGY > Vol. 123, N° 2 (2007) . - p. 74-79 Titre : Modification of silk with aminated polyepichlorohydrin to improve dyeability with reactive dyes Type de document : texte imprimé Auteurs : Xie Weiben, Auteur ; He Jinxin, Auteur ; Chen Shuilin, Auteur ; Guoqiang Chen, Auteur ; Peng Taozhi, Auteur Année de publication : 2007 Article en page(s) : p. 74-79 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : Reactive dyes have almost complete exhaustion and ideal fixation on aminated polyepichlorohydrin pretreated silk without addition of salt or alkali. The effects of varying pretreatments and dyeing conditions were studied. The dyeing behaviour of CI Reactive Red 15 on modified silk under pH 6 was investigated. Dyeings of modified silk showed good wash fastness, dry and wet rub fastnesses as well as light fastness. The quality of the dyed silks obtained after pretreatment was shown to be satisfactory and the dyeing effluent was less polluted.

Research in the cold pad–batch dyeing process for wool pretreated by hydrogen peroxide / Xue Zhao in COLORATION TECHNOLOGY, Vol. 125, N° 3 (2009)  

[article]  inCOLORATION TECHNOLOGY > Vol. 125, N° 3 (2009) . - p. 172-177 Titre : Research in the cold pad–batch dyeing process for wool pretreated by hydrogen peroxide Type de document : texte imprimé Auteurs : Xue Zhao, Auteur ; He Jinxin, Auteur ; Yi-Zhen Zhan, Auteur Année de publication : 2009 Article en page(s) : p. 172-177 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : The cold pad–batch dyeing process of wool pretreated by hydrogen peroxide was carried out with Lanasol reactive dyes and Realan reactive dyes. The influences of various conditions of the dyeing process, including urea dosage, sodium bisulphite dosage, pH value, batching time and the liquor pickup on colour yield, were analysed. Fixation, levelness of dyeing, dye penetration, colour fastness, breaking strength and elongation were compared between untreated and treated wool fabrics. The study showed that cold pad–batch dyeing of wool fabric is a good prospect for future use because of the resulting advantages, such as higher fixation yield, less energy usage and lower sewage discharge.
