In this work, we aimed to analyze suspensions of cationic starch by adding 5 wt%, 7 wt%, and 10 wt% of bentonite as a bilayer coating on kraftliner paper (85 g/m2). The controls were doubly-wet-and-dry and uncoated kraftliner paper. In a coating mach

A eficiência da deslignificação com oxigênio (pré-O2) é muito baixa para polpas de baixo número kappa e que contêm altas concentrações de ácidos hexenurônicos, pois o oxigênio não reage com esses ácidos, sendo mínima a eliminação de
