Abstract

In this work, the dyeing methods with ultrasonic technology and tradition method were investigated. Dye uptake and rubbing fastness as detection index of feather fibers were analysed. The optimum conditions of dyeing in feather fibers with ultrasonic wave technology were determined: weak acid dye: dyeing temperature 70°C, time 40min; reactive dye: dyeing temperature 90°C, time 50min. The results showed that in this dyeing conditions, dye uptake using ultrasonic technology can reach 89.9%, that increased 31.9% comparing with that using traditional method; rubbing fastness can be over 3 grade, and the dry rubbing fastness was raised by 0.5~1 grade as compared with the wet rubbing fastness. It was found that the effect of dyed feather fibers can be better by using ultrasonic technology, which were eco friendly and so give good effect to human in addition to values on garments, and provided the beneficial to test for development of feather fibers.
