Abstract

1300668 Wood pulp MOSCA MOSCON & CIA 5 May 1970 [12 June 1969] 21584/70 Heading D2W Wood is cut to provide shavings or chips having a thickness of 0.1-3mm, the chips are then artificially dehydrated and then impregnated with acid, alkaline or neutral liquor to produce pulp, the dehydration being to such an extent as to permit substantially uniform penetration of the liquor without dilution thereof. The chips may be further broken down before dehydration.
