Abstract
Only small amounts of O-acetyl-galactoglucomannans were sorbed onto fibres or fines from TMP, BTMP or CTMP, indicating a low surface coverage of cellulose. After deacetylation, about 30-45% of the galactoglucomannans were sorbed, the largest amount onto fibrils. Galactomannans (guar gum) were not sorbed onto flakes or ray cells. About 50% of the added galactomannans were sorbed onto fibrils from TMP or BTMP but only 25% onto CTMP fibrils.
