Dyeing of nylon 6 fabric with a bifunctional sulphatoethylsulphone reactive disperse dye / Yehya A. Youssef in COLORATION TECHNOLOGY, Vol. 123, N° 5 (2007)  

[article]  inCOLORATION TECHNOLOGY > Vol. 123, N° 5 (2007) . - p. 312-316 Titre : Dyeing of nylon 6 fabric with a bifunctional sulphatoethylsulphone reactive disperse dye Type de document : texte imprimé Auteurs : Yehya A. Youssef, Auteur ; Aballa A. Mousa, Auteur ; Reham Farouk, Auteur ; E. E. Allam, Auteur ; E. A. El-Kharadly, Auteur Année de publication : 2007 Article en page(s) : p. 312-316 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : A bifunctional reactive disperse dye containing two temporarily anionic sulphatoethylsulphone groups was synthesised and applied to nylon 6 fabric by exhaust dyeing at a variety of pH levels and temperatures. A monofunctional reactive disperse dye containing one temporarily anionic sulphatoethylsulphone group was also synthesised, and its dyeing behaviour was compared with the bifunctional dye. The bifunctional reactive disperse dye exhibited high exhaustion and total fixation yield under alkaline conditions. The results also indicate that the introduction of two temporarily anionic sulphatoethylsulphone groups of the bifunctional dye gave an enhancement in dyeing performance compared with that of the monofunctional dye. The dyes also showed very good levelling and fastness properties on nylon 6 fabric.

Neutral dyeing of wool and wool/polyester blend fabrics using sulphatoethylsulphone reactive-disperse dyes / Aballa A. Mousa in COLORATION TECHNOLOGY, Vol. 127, N° 5 (2011)  

[article]  inCOLORATION TECHNOLOGY > Vol. 127, N° 5 (2011) . - p. 304-309 Titre : Neutral dyeing of wool and wool/polyester blend fabrics using sulphatoethylsulphone reactive-disperse dyes Type de document : texte imprimé Auteurs : Aballa A. Mousa, Auteur ; Yehya A. Youssef, Auteur ; Reham Farouk, Auteur ; T. M. Ayiesh, Auteur ; M. H. Arief, Auteur Année de publication : 2011 Article en page(s) : p. 304-309 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Colorants réactifs Fibres polyesters Laine Sulfatoéthylsulfone Teinture -- Fibres textiles Index. décimale : 667.3 Teinture et impression des tissus Résumé : Two models of temporarily anionic sulphatoethylsulphone reactive disperse dyes were applied to wool, polyester and wool/polyester blend fabrics at different dyeing pH. Maximum exhaustion values and colour yield were observed at pH 7. The results showed that reactive disperse dyes containing bis-sulphatoethylsulphone reactive groups were more convenient for neutral dyeing of wool and wool/polyester blend fabrics if compared with a dye containing a mono-sulphatoethylsulphone group. Excellent to very good wet fastness properties on all dyed fabrics were achieved.

Organoclay-assisted vat dyeing of polypropylene nanocomposite fabrics / Yehya A. Youssef in COLORATION TECHNOLOGY, Vol. 137, N° 6 (12/2021)

Spinnable polymers were obtained by mixing PP master batches with 4 wt% MMT, possessing either tallow amine or tallow quaternary ammonium salt intercalating compounds with a pure untreated PP to MMT content of 0.5 wt%. After spinning, the prepared nanocomposites were drawn and knitted into fabrics for further testing and dyeing. The prepared PP nanocomposite fabrics containing hydrogenated tallow quaternary ammonium-based organomodified nanoclays exhibited higher colour strength (K/S) using vat dyes compared with those containing either octadecylamine or trimethyloctadecyl ammonium-based organomodified nanoclays and reference fabrics made from fibres spun without MMT clay content. The investigated vat dyes yielded relatively high K/S values on PP nanocomposite fabrics with very good to excellent wash, excellent fastness to bleaching with chlorine, perspiration, and good to excellent light fastness ratings.

Organoclays assisted vat and disperse dyeing of poly(ethylene terephthalate) nanocomposite fabrics via melt spinning / Aballa A. Mousa in COLORATION TECHNOLOGY, Vol. 134, N° 2 (04/2018)  

[article]  inCOLORATION TECHNOLOGY > Vol. 134, N° 2 (04/2018) . - p. 126-134 Titre : Organoclays assisted vat and disperse dyeing of poly(ethylene terephthalate) nanocomposite fabrics via melt spinning Type de document : texte imprimé Auteurs : Aballa A.

Langues : Anglais (eng) Catégories : Argile Etat fondu (matériaux) Extrusion filage Montmorillonite Nanoparticules Photostabilité Polyéthylène téréphtalate Résistance à la transpiration Résistance au nettoyage Teinture -- Fibres textiles synthétiques Textiles et tissus -- Propriétés mécaniques Index. décimale : 667.3 Teinture et impression des tissus Résumé : Polyethylene terephthalate nanocomposites containing six modified montmorillonite nanoclays were prepared by a melt compounding technique. The effect of intercalated compounds of montmorillonite on textile mechanical properties of resultant polyethylene terephthalate nanocomposite fabrics was investigated. Winding was not possible, when the polymers were first compounded with the desired amount of montmorillonite and then spun, as filament breakage occurred. Spinable polymer were only obtained by mixing polyethylene terephthalate master batches with 4 wt% montmorillonite, which contained tallow intercalating compound with pure untreated polyethylene terephthalate to a montmorillonite content of 0.5 wt%, thus decreasing the concentration of thermally degraded polymer chains. After spinning the fibres were drawn and knitted into fabric samples for further testing. The prepared polyethylene terephthalate nanocomposite fabrics using montmorillonite exhibited higher colour strength using vat and disperse dyes compared with those of the reference fabrics made from fibres spun without montmorillonite clay content and regular fabrics. The carbocyclic‐based vat dyes have higher colour strength values on polyethylene terephthalate nanocomposite fabrics if compared with heterocyclic‐based vat dyes. The colour fastness ratings for both vat and disperse dyeings secured very good to excellent washing and perspiration fastness on polyethylene terephthalate nanocomposite fabrics. All dyed fabrics showed excellent light fastness using vat and disperse dyes. The preparation of polyethylene terephthalate nanocomposite fabrics with improved textile mechanical and vat dyeing properties needs further investigations.
