” What can we learn from using mordants?” (in English, online)
In natural dyeing, mordants are often required. These substances help dye molecules bind to the fiber and can influence the final hue. Their effectiveness depends on the type of fiber, the dye used, and the mordanting method. The most commonly used mordants are various metal salts, historically among which alum-based compounds are particularly popular. How do mordants work, and what should be considered when using them?
Deb Bamford, University of Leeds, doctoral researcher. Deb Bamford is a doctoral student at the University of Leeds, School of Design. Her research interests include history of dyes, dyeing and textiles. Her thesis title is “Investigations to improve the mordanting process for natural dyes on cotton and wool using aluminium salts or alternative bio-mordants”. She is a member of the EU Horizon project Colour4CRAFTS project.
The lecture is part of a series “Textile Dyes of the Past and Future: sharing the Colour4CRAFTS Experience” begins, initiated by the EU Horizon project Colour4CRAFTS.
The webinar series brings together EU Horizon project Colour4CRAFTS members and important guests to discuss and share their knowledge on textile dyes of the past and future. The series is brought together by the University of Tartu and Viljandi Culture Academy in collaboration with the Estonian Academy of Arts.
EU Horizon project Colour4CRAFTS combines a multidisciplinary team of experts from research institutes and R&D companies to carry out studies of bio-based textile colouration in traditional historic perspective and in combination with cutting-edge technologies of colourants biosynthesis and waterless applications techniques. Colour4CRAFTS members are the University of Helsinki, University of Lapland, University of Tartu, KIK-IRPA, University of Leeds and PILI Bio.
