Abstract
Development of dyes with high fixation and salt-free dyeing process for cotton and silk is essential for the textile industry due to ecological and economical reasons. In this study, the synthesis of novel crosslinking polymeric dyes and its salt-free crosslinking dyeing method are described, and cotton and silk have been effectively dyed with the novel dyes. Excellent dye fixation of over 99% on silk and over 97% on cotton, were achieved in a padding process in the salt-free condition. The dyes showed excellent wet fastness values equal to those observed for the standard reactive dyeing.
