FIBRE PROPERTIES IN THE SPRUCE ROOT SYSTEM,
SVENSKA TRAFORSKNINGSINSTITUTET STOCKHOLM
Pagination or Media Count:
The root system of the spruce, calculated on the basis of dry bark-free wood, constitutes about 40 per cent of the weight of the part of the trunk normally used as pulpwood 10 per cent is in the stump, 25 per cent in roots more than 1inch in diameter and 5 per cent in the smaller roots. The possibilities of using this amount of wood for pulp have, of course, been considered. The barking problem has not been solved, but the unbarked wood has been cut and used for the cook. In the present study attention was centered mainly on the properties of the fibres. Conventional pulp tests were carried out, and the morphology of the wood was also studied.
