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]
Paper is made from wood pulp or recycled material. It may be used in packaging, drawing and sketching, or model making. Part of Design and Technology Specialist technical principles
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.

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mechanical method (generally used to make lower-grades of paper) is called the groundwood process, because the pulp was originally made by using huge stones to grind up logs.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 ...
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).
Papermaking - Pulping, Refining, Bleaching: Mechanical or groundwood pulp is made by subjecting wood to an abrading action, either by pressing the wood against a revolving grinding stone or by passing chips through a mill. The wood fibres are separated and, to a considerable degree, fragmented.
Pulp and paper are made from cellulosic fibers and other plant materials. Some synthetic materials may be used to impart special qualities to the finished product. Paper is made from wood fibers, but rags, flax, cotton linters, and bagasse (sugar cane residues) are also used in some papers.
