Differences between Scots pine and Norway spruce TMP pulps as revealed bt the HCL method
Ander, Paul; Daniel, GeoffreyAbstract
The HCl method was used to compare pine and spruce TMP pulps. Delignification gave much stronger fibre cleavage by HCl (3.5-5x for Stage 3) indicating that lignin and hemicelluloses protect the fibres from acid attack. Cleavage per fibre for TMP was similar as kraft pulps, while spruce TMP was more sensitive to HCl than pine TMP. A more robust secondary wall and a lower number of dislocations and weak points may be related to the higher refining energy needed for pine TMP pulpsKeywords
