Simultaneous removal of cellulose and bleaching. The cellulose-removal
process is a source of cellulose, removed from the fabric, which is trans-
formed by cellulose while producing hydrogen peroxide from dissolved
oxygen. The hydrogen peroxide formed can be used for bleaching.
However, cellulose removal must be executed as otherwise the hydro-
gen peroxide cannot attack the fabric for bleaching.
