Mechanical pulping Wikipedia
OverviewMechanical pulping processesMechanical pulps in the paper industrySee alsoA number of different mechanical processes exist: • Stone groundwood pulp (SGW) is produced by pressing the wood onto a rotating grinding stone. The grinding grits in the surface will penetrate into the surface of the wood and separate the fibers by a combination of compression, heating and shear.
Kraft process Wikipedia
OverviewHistoryThe processComparison with other pulping processesByproducts and emissionsFurther readingExternal linksThe kraft process (also known as kraft pulping or sulfate process) is a process for conversion of wood into wood pulp, which consists of almost pure cellulose fibers, the main component of paper. The kraft process entails treatment of wood chips with a hot mixture of water, sodium hydroxide (NaOH), and sodium sulfide (Na2S), known as white liquor, that breaks the bonds that link lignin, hemicellulose, and cellulose. The technology entails several steps, both mechanical and chemical. It is the dominant method for producin

Mechanical Pulping an overview ScienceDirect Topics
Kraft pulp constituted about 75% of wood pulp capacity in 2013; TMP and mechanical (stone grinding or milling) pulp 8–9% each; and semichemical, sulphite and dissolving pulp 2–4% each (FAO). Hemicelluloses are removed in dissolving pulps using higher temperature and acidity during sulphite pulping, and by acid prehydrolysis in alkaline processes ( Sixta, 2006, p. 7 ).
Comparison of Chemical Pulping and Mechanical Pulping
The pulping process is an important link in the papermaking industry. To learn why it is important, we have to start from the pulp. Pulp can be classified mainly into two types by the pulping methods: chemical pulp and mechanical pulp. The chemical pulp is produced through the chemical pulping process, while the mechanical pulp is produced through mechanical pulping.

Kraft process Wikipedia
History. A precursor of the Kraft process was used during the Napoleonic Wars in England. The kraft process (so called because of the superior strength of the resulting paper, from the German word Kraft for 'strength') was invented by Carl F. Dahl in 1879 in Danzig, Prussia, Germany. U.S. Patent 296,935 was issued in 1884, and a pulp mill using this technology began in Sweden in 1890.
