A PhD student and Knowledge Transfer Partnership (KTP) Research
Associate from The University of Northampton is working to find a
treatment for red rot, an age‑old problem affecting the
leather industry.
Anne Lama has been appointed to carry out a two-year KTP project
to research, design and implement a new generation of conservation
materials to consolidate leather and combat red rot.
Red rot is the acidic degradation of vegetable tanned leather
resulting in acid attack on both the collagen protein fibres and
the vegetable tannins. The leather gradually turns into a red
powder and, at present, it is an irreversible process.
Yvette Fletcher, Acting Head of Conservation at the Leather
Conservation Centre - a major international centre for leather
conservation, education and research housed at the University's
Park Campus - is working closely with Anne. She explained:
"The problem is usually found affecting leather from Victorian
times onwards. It was originally documented after leather chairs in
the library of a London club, which was heated by coal fires and
lit by gas lighting, started to deteriorate. The sulphur and
nitrogen oxides from incomplete combustion reacted with the
leather, causing de-tanning and gross breakdown of the material
itself. It is understood that this is only one of many contributing
factors."
Anne studied her MSc in Leather Technology at the University's
British School of Leather Technology and is due to submit her PhD
thesis in November, entitled 'The Impact of the Leather
Manufacturing Process on Bacterial Growth in Tannery Effluent'.
The KTP Research Associate is eager to talk to conservators,
archivists, librarians, bookbinders and anyone dealing with leather
who may have come across red rot. She said: "I am collecting
samples of old and new leather, with and without red rot, in order
to carry out tests and find out more about the causes and how to
cure it. Combating the problem would save so many pieces of history
from crumbling away and being lost for ever."
Anyone who would like to donate any leather samples to the red
rot research can contact Anne at lcc@northampton.ac.uk.
Anne and fellow PhD student Arthur Onyuka, were also recently
awarded funds by the Dr Dorothy Jordan Lloyd Memorial Trust,
administered by the Northampton-based UK Leather Federation, to
cover their travel expenses for the upcoming 30th IULTCS
(International Union of Leather Technologists and Chemists
Societies) Global Conference in Beijing, China, 11-14 October
2009.
Arthur will be presenting a full paper at the Conference to an
international and renowned audience, and Anne will present a poster
based on her PhD theses entitled 'The Impact of Beamhouse Processes
on Bacterial Growth'. The Conference will give them a valuable
insight into the international leather technologies and chemists
industry.
