Abstract

Results reported in this paper indicate that high alpha-cellulose pulps suitable for the manufacture of Filament Rayon and Tyrecord yarn can be produced from two species of tropica pines (P. pseudostrobus and P. greggi) by using acid -prehydrolyzed kraft process followed by multistage bleaching Dissolving-grade pulps were obtained inâ‰ˆ35-40% yield with â‰ˆ 93--95% alpha cellulose and â‰ˆ86-88% Elrepho (I S.O.) brightness by using C/E/H/D or C/E/H/D/ E/D bleaching sequences.
