Abstract
<B>PROCESSO DE RECICLAGEM POR EXPLOSãO A VAPOR DE FIBRAS E TECIDOS FABRICADOS A PARTIR DAS FIBRAS RECICLADAS<D> Fibras recicladas cuja tinta foi removida, modificadas por vapor, são capazes de formar folhas com maior volume, menor tração e maior porosidade. Conseq³entemente, as fibras modificadas apresentam aperfeiçoamento significativo em maciez, o que é de fundamental importância na fabricação de tecidos. Pode-se associar o descoramento para compensar a redução do brilho provocada pelo tratamento por explosão a vapor.
