国外水性液体活性染料制备方法的研究概况

粉状活性染料广泛应用于天然纤维、再生纤维和聚酰胺纤维的染色,但由于粉尘的环境污染,较差的润湿性,溶解耗能,不合理的加热冷却程序,正在被液体活性染料所替代。制备水性液体活性染料的方法是在染料溶液中选择性地加入助溶剂、非离子表面活性剂、己内酰胺、蒽醌-2-磺酸等助剂、pH稳定剂和适量水,调节pH在3~7。不同的活性染料须用不同的助剂和配方,脱盐是制备液体活性染料的新课题。现在,已经制备了使用方便,不改变给色量、流动性和贮存性能、能用泵输送自动计量的水性液体活性染料,且已广泛应用于传统工艺的染色和印花中。

Application of sodium benzoyl thiosulphate from aqueous solution to wool and its effect on substantivity of disperse dyes. Part 1: synthesis and characterisation of sodium benzoyl thiosulphate

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.

Synthesis and Application of Some New Reactive Chlorohydrin Dyes

Azo and phthalocyanine dyes carrying the chlorohydrin group, as the precursor of the reactive epoxy group, were prepared using new catalyzed reactions. The reactive group is attached to the coupling component in some cases and to the diazonium component in other cases. A phthalocyanine dye carrying two reactive groups was also synthesized. The dyeing of cotton, wool and multifibre fabrics was studied, under different dyeing conditions. Various techniques of dyeing and printing were used. Exhaustion and padding methods were investigated for dyeing, and direct, reserve and discharge methods for printing. One–stage and two–stage procedures were employed for both printing and dyeing. It was found that the chlorohydrin reactive dyes prepared in the present work could be applied by nearly all known methods of dyeing and printing on cotton, wool, viscose rayon, nylon and acrylic fibres. The dyeings obtained had satisfactory fastness properties and showed fairly good dye fixation on the substrate.     

Prediction of recipes for cotton cationisation and reactive dyeing to shade match conventionally dyed cotton

Cationisation allows cotton to be dyed with anionic dyestuffs (including anionic pigment dispersions) without the need for salt, and with decreased usage of dye, water, and energy. Appropriate cationisation levels play a part in dyeing properties such as fabric levelness, in fastness properties such as lightfastness, and in the overall cost of the cationisation treatment. The objective of this work is to assess whether it is possible simultaneously to predict a dye recipe and cationisation treatment level for cotton to yield a colourless or nearly colourless dyebath at the completion of the dyeing to match the shade of conventional fibre reactive dyeing of cotton. It has been shown that it is possible to model a cold pad batch cationisation process, relate the colour yield data and cationisation level for individual dyes, and finally predict a dyeing recipe and the required corresponding cationisation treatment to match the shade of conventional fibre reactive dyeing of cotton. The predicted dye recipe and cationisation amount yield colourless or nearly colourless dyebaths at the conclusion of the dyeing process.     

Recent developments in the optimised dyeing of cellulose using reactive dyes

To obtain the optimum conditions for dyeing cellulosic fibre with reactive dyes, it is necessary to find out how dyeing results depend upon the properties of the dyes and the fibres. The relationships between the rates of dyeing, dyeing equilibria, types of dye and additions of auxiliaries are important. Based on data that are already available or easy to acquire, it is possible to control the pH of the dyebath and the addition of auxiliaries to obtain optimum exhaustion and fixation for each reactive dye. The advantages to be gained are shorter dyeing times, better dyeing reproducibility and better levelness.     

Synthesis and evaluation of a novel blue cationic reactive dye for modified nylon 6.6 ‘Tactel Coloursafe’

A novel blue cationic reactive dye (dye 1 ) based on an azo benzothiazole derivative and possessing an acrylamido reactive group, was synthesised and evaluated on dyeing Coloursafe modified nylon 6.6 at optimum pH. Benzothiazole quaternary dye was chosen as a target as this is known to be very strong chromophically. Evaluation of the technical properties of dye 1 showed that it fixed efficiently to nylon under acidic dyeing conditions. As it was necessary to prove that fixation occurs via a covalent bond, the dyeing properties of a non‐reactive cationic dye, (CI Basic Blue 41), on dyeing nylon 6.6 at optimum pH were evaluated. CI Basic Blue 41 was similar in structure to dye 1 and would be capable of forming an ion–ion bond with the fibre. Evaluation of the technical properties of dye 1 proved that, in all cases, its fixation efficiency and build‐up properties were far better than that of CI Basic Blue 41.
