Ultrasonic Assisted Dyeing of Angora Fi̇bre
Journal Title: Fibres and Textiles in Eastern Europe - Year 2016, Vol 24, Issue 5
Abstract
In this study it was aimed to determine the effect of ultrasound usage on the colour yield in dyeing angora fibres, and it was found that dyeing in the presence of ultrasound energy increases the dye-uptake of angora fibres, hence higher colour yield values were obtained. According to experimental results, it can be said that at all points the colour yield values were higher in the presence of ultrasound than in its absence . The difference between them was greater for darker shades and for dyeing carried out in an acidic medium (pH 5), and also for moderate dyeing periods (90 min.). Furthermore there is no important difference between washing fastness, alkali solubility and strength values of fibres dyed in the presence and absence of ultrasound.
