One preferredmethod comprises forming a treated pulp by added to a papermaking pulp a syntheticlayered silicate, a peptizer and at least one polymer. The synthetic layered silicatepreferably comprises a synthetic hydrous sodium lithium magnesium silicate and thepolymer is selected from cationic, nonionic and amphoteric polymers.
