Abstract

De-inked recycled fibers modified by steam are able to form handsheets with higher bulk, lower tensile and a higher porosity. Consequently, the modified fibers show significant improvement in softness which is fundamental importance in tissue manufacturing. Bleach can be added to compensate for the brightness reduction caused by the steam explosion treatment.
