Abstract
"COMPOSTOS QUìMICOS E MéTODOS PARA A REMOçãO DE CORANTE". São descritos compostos químicos e métodos para a remoção de corantes a partir de fibras de poliéster, de modo específico de fibras de poli(tereftalato de etileno) ("PET"). Os compostos e os métodos são úteis de forma específica para a remoção de corante a partir de tecidos de painel feitos a partir de fibras de PET reciclado. O método envolve contactar o PET com um composto para a remoção de corante em um recipiente que possa ser vedado. O conteúdo do recipiente é agitado e é aquecido para ser alcançado um aumento na temperatura na pressão. Em seguida a um período de resfriamento, o PET é removido e enxaguado com água. O composto para a emoção de corante inclui uma solução aquosa de pelo menos um agente de nivelamento.
