unbleached sulfite pulp
A tan or brown paper pulp that requires 2.5 to
4.5% chlorine to bleach it to a suitable white
color. Characteristics expected of this type of
pulp include softness, absorbency, cleanliness,
and brightness. Peroxide is sometimes used in a
single stage or final stage of bleaching to gain
brightness and improve brightness stability. (17 , 98 )
