Due to someinconveniences caused by synthetic dyes that are widely used today, in thisstudy, ultrasonic dyeing of wool fabric withHibiscus sabdariffawas carried outafter environmental-friendly air vacuum plasma application which increasedthe absorption of the dyes into the textile material. According to the perfor-mance results, colour strengths of the wool fabrics were increased significantly.Surface morphology analysis was carried out and etching effects of air vacuumplasma treatment were clearly seen on the micrographs of the treated woolfabrics. An environmental-friendly green process was achieved through thisstudy and it was concluded that vacuum air plasma treatment could be analternative green-process as a pretreatment to increase the dye up-take of natu-ral dyeing treatment. Moreover, in this study, a feed-forward neural network(FFNN) model was presented and used for predicting the dyeing properties(L,a,bandK/S) of samples. The experimental results showed that the pre-sented model achieves the regression values greater than 0.9 for all dyeingproperties. Consequently, it was considered that the proposed FFNN was suc-cessfully modelled and could be efficiently utilised for dyeing characteristics ofwool fabrics dyed with natural dye extracted fromHibiscus sabdariffaeninfo:eu-repo/semantics/embargoedAccessSurface modıfıcatıontemperature plasmapretreatmenttextılesperformanceımprovefıbersArticleQ2WOS:000905867700001N/A2-s2.0-8514537073010.1111/cote.12665
