In this study, the natural dye extracted from the fruits of Sambucus Ebulus L. (Dwarf Elder) was used to dye silk fabric. Prior to the dyeing process, the samples were exposed to oxygen plasma pre-treatment at low frequency for 1 and 5 minutes. Following the plasma pre-treatment, the samples were dyed with the natural dye by the use of conventional and microwave dyeing methods. After dyeing procedure, the samples were treated with three different fixing agents. Finally, the effect of plasma pre-treatment and microwave energy, and type of fixing agent as a dyeing procedure on colour fastness to light, rubbing and washing and also the colour strength of the samples were investigated. According to the results, the increase on plasma treatment time and microwave energy increased the colour strength of samples. The fixing agent treatment did not affect much as the colour fastness properties of dyed samples.

In this study, cotton fabric was treated with oxygen, nitrogen and argon plasma application. The plasma application was carried out for 10 minutes at low frequency. Firstly, contact angle of plasma treated samples was measured at the end of plasma treatment. The results showed that the plasma treatment causes to increase the hydrophility of samples. Moreover, it was seen that the type of gas affects the hydrophilic properties of samples. After then the samples were left during 1 month with different conditions which were under normal condition and covered with aluminum foil. Finally, the contact angle of plasma treated samples was measured after 1 month in order to determine the durability effect of plasma treatment on properties of cotton fabric. After the contact angle measurements, the results were evaluated with statistical analyses in terms of the type of gas and storage conditions of plasma treated samples. The results demonstrated that the storage conditions and type of gas affect the hydrophilic properties of plasma treated cotton fabric after 1 month.
The investigation of the effects of plasma treatment on the dyeing properties of polyester/viscose nonwoven fabrics
(Elsevier Science, 2015-01-01) Canbolat, Şeyda; Kılınç, Mehmet; Kut, Dilek; Şener, S.; Saridoğan, E.; Staub, S.; KUT, YAŞAR DİLEK; Uludağ Üniversitesi/Mühendislik Fakültesi/Tekstil Mühendisliği Bölümü.; Şener, S.; Sarıdoğan, E.; Staub, S.; 0000-0002-9059-0838; AAH-4335-2021
In this study, Polyester/Viscose (PET/CV) nonwoven fabrics were treated with oxygen plasma application. The plasma application was carried out for 1and 10 minutes at low frequency. After then, the samples were dyed with disperse dyes. Where same samples were dyed with carriers, the others were dyed without carriers. Finally, the effects of plasma treatment on dyeing properties of PET/CV nonwoven fabrics were investigated at 3% darkness. The aim of this study is that the effect of hydrophility caused by the plasma application on dyeability properties of samples was investigated.
