摘要: Compositions and methods that preserve enhance the brightness of pulp, also improve color pulp or paper, when applied during different stages a paper making process, are disclosed. The compositions maintain brightness, prevent yellowing, performance products. can include mixture reducing agents optical brighteners, chelants, polycarboxylates, other additives. borohydride, such as sodium any agent, sulfite bisulfite.
