Impression tridimensionnelleIndex. 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.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Freshwater is an increasingly scarce resource that is extensively used in textile wet‐processing. In seeking to identify alternative low freshwater‐usage coloration technology, this study examined the potential use of seawater (SEAW) as the dyeing medium for wool coloration using a range of reactive dyes. Initially, the dyeing behaviour of the wool fabric in simulated seawater (SSW) was compared with conventional dyeing from distilled water (DW) using α‐bromoacrylamide‐based Lanasol dyes and sulphatoethyl sulphone‐based Remazol dyes. These preliminary studies demonstrated that comparable coloration could be achieved in the SSW medium based on an assessment of the dye exhaustion, dye fixation, colour yield and levelness. Subsequent dyeing studies of wool using Mauritian seawater with both the Lanasol and Remazol reactive dyes confirmed that, based on the dye exhaustion, dye fixation, colour yield and levelness, comparable coloration could be achieved, highlighting the possibility of substituting freshwater with seawater as the dyeing medium.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : In this study, cotton fabric and nylon fabric were dyed with a range of commercial sulphur dyes and the light and wash fastness of the coloured fabrics was investigated. The effect of after-treating the coloured cotton and nylon fabrics with a tannin-based commercial product, Bayprotect Cl, in the presence or absence of sodium sulphate in the treatment bath, was found to significantly improve the light fastness of the sulphur-dyed cotton, and the photoprotective effect was partially stable to ISO 105-C06 washing. In addition, the tannin-based after-treatment also improved the colour stability of the dyed fabrics to the perborate-based ISO 105-C06 washing. The possible mechanisms for the improved fastness properties are also discussed. The application of sulphur dyes to nylon is potentially commercially useful but has been limited because of the reported poor light fastness of the dyeings. The photoprotective effect of the tannin-based after-treatment was investigated with a view to providing the necessary commercial performance. However, it was established that on this fibre, the light fastness improvement was marginal, and the associated wash fastness to oxidative bleach-based ISO 105-C06 washing was limited.

Carr, Auteur ; Mark Sumner, Auteur ; Muriel Rigout, Auteur Année de publication : 2021 Article en page(s) : p. 604-614 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Colorants au soufre Les colorants au soufre sont des colorants utilisés pour teindre de façon assez économique des fibres cellulosiques, principalement dans des nuances sombres (noir, brun, bleu foncé). Insolubles à l'état oxydé, ils sont rendus solubles par réduction à la soude caustique pour la teinture, dans un procédé analogue aux colorants de cuve, plus chers.
Les colorants s'obtiennent par action du soufre sur des composés organiques, notamment sur le 2-4-dinitrophénol (Sulphur Black 1) ou le toluène-2-4-diamine et la 4-nitroaniline (Sulphur Brown 12).

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Cotton can be coloured by dyeing and printing using either dye or pigment colourants. Pigments are insoluble in water but can be dispersed in a polymer print binder and heat-fixed to the fabric. Vat and sulphur dyes similarly have low solubility in water but through alkali/reduction can be solubilised and exhausted onto the cotton fibre. Following their reoxidation, the dyes are insolubilised in the fibre and, like pigment prints, in general exhibit good wash fastness. In this study, sequential acid/alkali/peroxide or acid/dithionite/peroxide treatments were investigated as a means of removing pigment/polymer prints and common sulphur and vat dyes from coloured cotton fabric. Using the sequential acid/dithionite/peroxide treatment, up to 97% of both sulphur and vat colourants could be “stripped” from dyed cotton producing a white cellulosic feedstock material that could be used for “new” fibre regeneration. By contrast, the “stripping” of the pigment/polymer binder colourant system was less predictable and less complete and is probably a reflection of the different chemical natures of the polymer binder and pigments. This contrasting behaviour highlights the range of chemistries applied to cotton and that developing a universal single treatment to strip out all finishes may be problematic.

This study presents a novel one-bath/two-stage exhaust finishing process to improve the oxidative wash fastness of CI Leuco Sulphur Black 1-dyed cotton fabric. The effect of the combined Tinofix ECO and Bayprotect Cl after-treatment was to impart better colour fastness to oxidative International Organisation for Standardisation (ISO) 105 CO9 washing of the dyed cotton compared with those dyed fabrics after-treated with Tinofix ECO alone. In addition, while the dyed fabrics rub and light fastness performances were unchanged by the after-treatments, some improvement in the tensile strength of the combined Tinofix ECO and Bayprotect Cl after-treated fabrics was observed.
