This work investigates the dyeability of gray cotton fabric that has been pre-treated and scoured using an alternate water-free technique composed of electron beam (EB) irradiation and supercritical carbon dioxide (scCO₂). The investigation was conducted for diazo and anionic anthraquinone reactive dyes. The effects of the EB irradiation dose and treatment conditions in scCO₂ on the color strength, levelness and color fastness properties are also explored.

The results show that the fabric exhibited higher color strength for all dyes in the absence of EB irradiation. With an increase in EB irradiation dose, it was discovered that the color strength and shade decreased. However, higher color levelness showed that the dye was more uniformly absorbed at higher EB irradiation dose as opposed to the non-irradiated fabric. Additionally, scouring in scCO₂ produced fabric with better dyeability than untreated fabric. However, in the scCO₂ treatment, a few variations between the various additions were found. Finally, the fastness characteristics of the dyed fabric were shown to be improved by pre-treatment with EB irradiation and scCO₂.

_{这项工作研究了使用由电子束 (EB) 辐射和超临界二氧化碳 (scCO 2} ) 组成的替代无水技术预处理和洗涤的灰色棉织物的可染性。对重氮和阴离子蒽醌活性染料进行了调查。还探讨了scCO ₂中电子束辐照剂量和处理条件对色强度、匀染性和色牢度性能的影响。

结果表明，在没有电子束辐照的情况下，织物对所有染料都表现出更高的颜色强度。随着 EB 照射剂量的增加，发现颜色强度和色调降低。然而，较高的颜色水平表明，与未照射的织物相比，染料在较高的 EB 照射剂量下被更均匀地吸收。此外，在 scCO ₂中洗涤产生的织物比未处理的织物具有更好的可染性。然而，在 scCO ₂处理中，发现各种添加物之间存在一些差异。_{最后，染色织物的牢度特性显示通过使用 EB 辐照和 scCO 2}进行预处理得到改善。
