Abstract
Totally Chlorine Free (TCF) and Elemental Chlorine Free (ECF) single- and multistage sequences were used to bleach whole stem kenaf pulp. The results indicated that in contrast to unbleached kraftwood pulps kraft kenaf pulps could be easily bleached to a brightness of 9I.4 using a four-stage TCF Q (PO)QrP bleaching sequence. The ECF bleached pulps had slightly higher selectivity and yield than those of TCF bleached pulps. The strength properties of the TCF tQ (PO)QrPl and ECF (DTEDTEP) bleached pulps were comparable with the exception that tear index was slightly higher and tensile index slightly lower for TCF pulps.
