Abstract

En fremgangsmåte til minskning av mengden væske som ble værende i masse som skal blekes. Det tilsettes et anionisk eller nonionisk overflateaktivt stoff med formelen: R-X(CH2CH20)nYZ Ved hjelp av den foreliggende oppfinnelse er det mulig ved vaskingen å minske overføring av forurensninger til etterfølgende stadium i prosessen.
