soda pulp
A chemical wood pulp produced by high temperature
digestion of papermaking material with sodium
hydroxide. The soda pulp method is used in making
paper from poplars, birches. oaks, and other
deciduous trees. Papers containing a high
proportion of soda pulp are very white and soft,
and possess high bulk and opacity but low
strength. Soda pulp is frequently used to give a
soft finish to a sulfite-pulp base paper. (17 , 143 , 198 , 320 )
