Pulp mill — Wikipedia Republished // WIKI 2

Pulp mill. Quite the same Wikipedia. Just better. Chemical pulping processes such as the kraft (or sulphate) process and the sulfite process remove much of the hemicelluloses and lignin. The kraft process does less damage to the cellulose fibres than the sulfite process, thereby producing stronger fibres, but the sulfite process makes pulp that is easier to bleach. Get price
