Resumo

A migração de corantes é um problema para os conservadores de têxteis, pois pode causar danos significativos nos objectos e impedir o seu tratamento por via húmida. Com a introdução dos geles de limpeza em conservação, surgiram novas oportunidades para esses tratamentos difíceis. Este artigo descreve a limpeza de uma peça de seda danificada devido à migração de corantes dos
fios do bordado para o fundo branco. Investigámos se, através do uso de gel de agarose com uma solução aquosa preparada com soluções-tampão de pH e quelantes, pode ser evitada a continuação da migração dos corantes durante o tratamento por via húmida. As soluções de siloxanos octametilciclotetrasiloxano (D4) e decametilciclopentasiloxano (D5) foram também testadas devido à possibilidade do seu uso, como barreiras de líquido, para protecção do bordado. O método de limpeza desenvolvido foi eficaz na prevenção da continuação da migração dos corantes, mas as manchas iniciais não puderam ser removidas completamente. É necessária investigação adicional com vista à optimização deste método.
