Evaluation of Some Reactive Disperse Dyes for Sublimation Transfer Printing of Wool

The transfer printing of wool by the sublimation method using a number of low–molecular–weight dyes containing chloro– and bromo–acetyl, chloroacetamido, chloro– and bromo–propionamido, 2–bromoacryloyl, 2–chloroethylamino and epoxy groups has been examined. To achieve build–up of the dyes to heavy depths, it was necessary to pretreat the wool with a polymer or surfactant and to steam the prints after transfer of the designs. Several dyes exhibited good fastness properties on pure wool and on a wool–polyester blend fabric.

Studies on Some New Reactive Disperse Dyes

The preparation of some new reactive disperse dyes which can be used for dyeing 100% synthetic and fibre blends is described. The preparation of some disperse dyes containing a chlorohydrin group is also described. This radical is the precursor of the epoxide reactive group in the active form of these dyes. Dyeings produced on various fibre blends by a two–stage high–temperature and by a carrier–dyeing technique are assessed. It was found that dyeings produced by the high–temperature technique were brighter, more level and possessed much better technical properties than those obtained using the carrier–dyeing method. The fastness properties of dyed samples were determined and found to be comparable with those of conventional disperse and reactive dyes. The colour yield was also determined in order to examine the possibility of obtaining deep dyeings on blended fibres, and to evaluate the potential commercial use of these dyes for dyeing blends as well as 100% synthetic–polymer fibres.

Factors Affecting Dye Transfer in Conventional Printing with Disperse Dyes

The conventional printing of polyester materials with disperse dyes and alginate thickeners has been studied. The factors governing dye transfer were investigated using isolated films of the thickener. Alginates block dye transfer completely. Special geometrical conditions in the thickener layer are postulated and substantiated to explain the printing process (G model, d/l ratio). A major factor is direct contact between dye and substrate. The geometrical model explains only some of the facts. At high concentrations of dye, structural changes (S effect), also reported by other authors, are observed in the alginate la yer. These changes make it easier for the dye to escape from inside the layer. Fixation accelerants are especially useful for demonstrating the S effect. The S concept is corroborated by kinetic observations and by the evidence of a system of channels inside the print film. Light microscopy, transmission electron microscopy and scanning electron microscopy were used to identify the film structures and localise the dye.     

浅谈分散染料与活性染料复配技术（二）

分散染料与活性染料已成为纺织染料的主要品种。近十余年,通过商品化技术进行染料复配,能获得比单一染料性能优异、颜色更深的品种,这项技术成为西欧著名染料企业获得高额利润的核心。分散染料与涤纶同为非离子有机化合物,通过溶解度参数预测染料之间以及染料与纤维的相互作用,作为筛选和设计复配染料的组分。活性染料通过测试染料特征值SERF以及无机性值（I）／有机性值（O）的比值,决定单一染料的组成。上述两种方法作为预测复配染料中每一染料的性能,最终通过应用实验验证,是复配技术最为有效和简便的方法。除了为染料企业制造复配染料提供了一项技术,也为染料应用者在三原色以外如何选用拼色中的补充染料提供了可靠的依据。
