Investigation of the effect of the dyeing method on the dyeing properties of silk fabric dyed with natural dye
MetadataShow full item record
In this study, silk fabric was dyed with the natural dye extracted from blueberry (Vaccinium corymbosum L.) via ultrasonic, microwave and conventional methods. One of the samples dyed via conventional method was treated oxygen plasma treatment whereas the other was mordanted with aluminium potassium sulphate prior to the dyeing process. The colour and fastness properties of the dyed fabrics were investigated and compared with each other in terms of dyeing method. The physical structure of samples was analysed with scanning electron microscope (SEM). The chemical structure of samples was characterized by Fourier transform infrared spectroscopy (FTIR ATR). According to the results, the samples dyed via microwave method had the best results in terms of colour properties. Furthermore, when compared with one another in terms of dyeing methods, there were no significant differences between fastness properties of dyed samples.
