Abstract

Treatment of PET fabrics with alkali, chitosan and Al-mordanting has been carried out and the role of the chitosan coating in the dyeing process was clarified. The pre-treatment was effectively evaluated differences in dyeing behavior between its treated and untreated PET fabrics using wood of Caesalpinia sappan. The pre-treated on PET fabrics has been examined by SEM and evidence for the presence of chitosan sought using a air permeability test. Similar colour fastness by computer color matching(CCM) obtained on both untreated and pre-treated PET fabrics. The pre-treated PET was found to be of a deeper hue to that of its dyed untreated PET and, despite of its better colour depth, the wash fastness of the pre-treated dyeing was comparable to that of its dyed untreated PR. The application of chitosan or mordanting reveled that pre-treatment imparted to the PET additional functional groups that were available for coordination with the Brazilin.
