Abstract

"COMPOSIçãO ALVEJANTE, PROCESSOS DE ALVEJAMENTO DE UM SUBSTRATO E DE TRATAMENTO DE UM TêXTIL, USO DE UM LIGANDO QUE FORMA UM COMPLEXO COM UM METAL DE TRANSIçãO, LIGANDO, E, COMPLEXO". A invenção refere-se aos substratos cataliticamente alvejados, especialmente tecidos de roupa suja, com oxigênio atmosférico ou ar. Um processo de alvejamento de um substrato é proporcionado o qual compreende a aplicação no substrato, em um meio aquoso, de um ligando especifico de uma classe selecionada que forma um complexo com um metal de transição, o complexo alvejando cataliticamente o substrato pelo oxigênio atmosférico. Também é proporcionada uma composição aquosa alvejante substancialmente destituída de alvejante de peroxigênio ou de um sistema alvejante gerador de ou baseado em peróxido. Também é proporcionado um processo de tratamento de um têxtil tal como um tecido de roupa suja por meio do qual um complexo catalisa o alvejamento do têxtil pelo oxigênio atmosférico após o tratamento. O catalisador pode ser usado na forma seca, ou em um licor que é então seco, tal como um fluido aquoso de tratamento de tecido por pulverização ou um licor de lavagem para a limpeza de roupa suja, ou um fluido não-aquoso para limpeza a seco ou um fluido de aerossol para pulverização. O processo pode conferir benefícios de limpeza ao têxtil após o tratamento. Também é proporcionado um têxtil seco possuindo um catalisador aplicado ou depositado sobre o mesmo, por meio do qual o alvejamento pelo oxigênio atmosférico é catalisado sobre o têxtil.
