Non-chrome focus for AAQTIC conference
04/04/2011
After a welcome address from AAQTIC president, Patricia Casey, Enrique Comes from Barcelona-based Cromogenia Units led the discussion. Free access to his presentation (in Spanish) is available on AAQTIC’s website. It is based on a paper that Mr Comes had writtten with colleagues, Ramón Palop and Olga Ballus and presented previously in Spain.
He explained that the purpose of the paper was to respond to the significant demand for chrome-free leather that tanners are facing now, especially for footwear and upholstery. The application of adehyde polymers was studied, and a wet white process was developed. The authors analysed the optimisation of the retanning process, comparing different synthetic retanning agents, as well as tara and mimosa. These concepts were applied to developing a complete process for non-chrome leather that can be adapted to different articles.
This was the third time Mr Comes had travelled from Barcelona to present a paper to AAQTIC, continuing a connection that his colleague Dr Palop first established some years ago.
Technicians from different tanneries participated in the event, which concluded with a pizza party hosted by Units Sudamericana, Cromogenia Units’s Argentinean subsidiary.
