Abstract

In the field of supercritical fluid dyeing, research on dye compatibility remains limited, and the interactions between dyes and their compatibility mechanisms remain poorly understood. This situation has significantly hindered the widespread industrial adoption of supercritical waterless dyeing technology. Thus, developing stable and reliable dye formulations is crucial for facilitating its transition to industrial applications. Based on this, this study investigated the kinetic behavior and compatibility of three commonly used dyes: Disperse Blue 79 (DB 79), Disperse Red 167 (DR 167), and Disperse Orange 30 (DO 30) in the supercritical CO₂ dyeing system. First, the lifting curves and dyeing rate curves of the three dyes were analyzed. From the highly consistent trend of these curves, it can be inferred that they will have good compatibility in their combinations. Then, the adsorption and diffusion processes of these three dyes during dyeing process of polyester in supercritical CO₂ were investigated in detail from a kinetic perspective. It was found that chemical adsorption played an important role and there was a certain resistance during the adsorption process. The diffusion capabilities of the three dyes were also compared at different temperatures. In addition, the compatibility relationships between DB 79, DR 167, and DO 30 were further explored through specific color matching experiments. The stripping results of the blended dyes aligned closely with their initial blending ratios, confirming the exceptional compatibility of DB 79, DR 167, and DO 30.

分散蓝79、分散红167和分散橙30在超临界二氧化碳染色中的染色动力学和相容性

在超临界流体染色领域，对染料相容性的研究仍然有限，对染料之间的相互作用及其相容性机制的了解仍然很少。这种情况严重阻碍了超临界无水染色技术在工业上的广泛应用。因此，开发稳定可靠的染料配方对于促进其向工业应用的过渡至关重要。在此基础上，研究了三种常用染料：分散蓝79 （db79）、分散红167 （DR 167）和分散橙30 （DO 30）在超临界CO2染色系统中的动力学行为和相容性。首先，分析了三种染料的提升曲线和染率曲线。从这些曲线高度一致的趋势可以推断，它们的组合将具有良好的相容性。然后，从动力学角度详细研究了这三种染料在超临界CO2中对涤纶染色过程的吸附和扩散过程。发现化学吸附起重要作用，在吸附过程中存在一定的阻力。比较了三种染料在不同温度下的扩散性能。此外，通过具体的配色实验，进一步探讨了db79、dr167和DO 30之间的相容性关系。混合染料的剥离结果与其初始混合比例密切相关，证实了DB 79， DR 167和DO 30的特殊相容性。

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
