| 中文摘要: |
| 超临界CO2染色技术从根本上解决了水污染严重的问题，在超临界CO2染色方法中，超临界CO2喷染方法因结合了传统喷染和超临界CO2染色方法的优点，具有广阔的应用前景。笔者首先对多种超临界CO2喷染方法进行了阐述，其共同特点为溶解有染料的超临界CO2经过喷嘴喷向被染物，在快速降压膨胀区实现被染物的上染。其次，笔者对基于不同喷染方法的喷染装置进行了介绍，包括：多孔式纺布喷染装置、纱线喷染装置、旋转式对喷染色器、单喷嘴对喷染色装置及收放式对喷染色器。最后，笔者提出今后应从以下几方面深入研究：如何实现喷染设备工业化；大型设备内部流场的上染符合性和均匀性是否能够满足染色上染率和均匀度要求；迷宫密封处的泄漏量是否在可控范围内。 |

| Supercritical CO2 dyeing technology fundamentally solves the problem of serious water pollution. Among the supercritical CO2 dyeing methods, supercritical CO2 spray dyeing method has broad application prospects because it combines the advantages of traditional spray dyeing and supercritical CO2 dyeing methods. A variety of supercritical CO2spray dyeing methods were described. The common feature is that supercritical CO2 dissolved with dye is sprayed to the dye through the nozzle, and the dying process is realized in the rapid decompression expansion zone. Secondly, the spray dyeing devices based on different spray dyeing methods were introduced, including porous fabric spray dyeing device, yarn spray dyeing device, rotary counter spray dyeing device, single nozzle counter spray dyeing device and retractable counter spray dyeing device. Finally, the following aspects should be further studied in the future: how to realize the industrialization of spray dyeing equipment, whether the dyeing compliance and uniformity of the flow field in large equipment can meet the requirements of dyeing uptake and uniformity, and whether the leakage at the labyrinth seal is within the controllable range. |
