Pulp is a fibrous lignocellulosic material prepared by chemically, semi-chemically or mechanically producing cellulosic fibers from wood, fiber crops, waste paper, or rags. Mixed with water and other chemicals or plant-based additives, pulp is the major raw material used in papermaking and the industrial production of other paper products. [1][2]
Aug 12, 2023 · Paper and Pulp, often known as pulp, are fibrous substances that are the main raw materials for the production of paper, manufactured from plant fiber using various pulp processing techniques. Cellulose, hemicellulose, lignin, pigment, resin, pectin, and ash are a few of the main components of pulp.
Paper pulp, raw material for paper manufacture that contains vegetable, mineral, or man-made fibers. It forms a matted or felted sheet on a screen when moisture is removed. Except for certain special papers (such as asbestos paper), nearly all papers are made of cellulosic (vegetable) fibers.

At a chemical level, paper is made of cellulose fibres pressed and bound together by hydrogen bonds, but it’s the crucial pulping step that accounts for paper’s unusual strength. As the wood ...
Oct 9, 2024 · Pulp is a primary material used in the production of paper and other paper-related products. It is a fibrous substance made from plant-based materials, typically wood, but also from other sources like recycled paper, cotton, or agricultural residues (e.g. hemp, wheat and straw).
Paper 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.
Oct 28, 2022 · Pulp is prepared for papermaking machines either mechanically or chemically. The mechanical method (generally used to make lower-grades of paper) is called the groundwood process, because the pulp was originally made by using huge stones to grind up logs. Nowadays, pulp is prepared by giant machines that cut, wash, chop, beat, and blend wood ...
