Abstract

Fractionation on the basis of length provided two fractions that respondedvery differently to bleaching agents. The long fraction responded better to peroxide than hydrosulphite and reached an ISO brightness of 75% with a QPY sequence; the short fraction responded oppositely and only reached 56% with a QPY sequence. Diverting all or a portion of the fines to another end-use would help increase the final brightness, but might affect opacity and printing properties.
