Abstract

"SISTEMA DE DESCOLORAçãO E EXTRAçãO DE CORANTE, E, PROCESSO PARA A EXTRAçãO DE UM CORANTE DE MATRIZES DE FIBRA ORGâNICA E DESCOLORAçãO DO CORANTE" Materiais têxteis tingidos na matriz de acetato de celulose. triacetato de celulose, seda, lã, linho, náilon, material acrílico, poli(tereftalato de etileno), algodão, e raiom são extraídos de seus corantes em um sistema de extração de corantes compreendendo um agente redutor em um banho aquoso produzido pela reação de um bissulfito com aproximadamente 0,35%, ou menos, de um boro-hidreto, em peso, do material têxtil. O boro-hidreto pode ser adicionado a um banho aquoso já contendo o bissulfito e o material têxtil ou o boro-hidreto e o bissulfito podem ser misturados em um tanque de adição e a mistura adicionada ao banho aquoso. Agentes quelantes, agentes sequestrantes, retardadores de fogo, e eliminadores de odor não necessários.
