Definition

Noun: - A fibrous material produced by mechanically or chemically processing wood. It consists of cellulose fibers and is the primary raw material used in the manufacture of paper, cardboard, and some cellulose-based products like rayon.

Examples
  • Noun:
    • The factory produces wood pulp from sustainably harvested pine trees.
    • Most newspapers are printed on paper made from recycled wood pulp.
    • The chemical process separates the lignin from the cellulose to create a high-quality wood pulp.
Advanced Usage
  • "Bleached wood pulp": Pulp that has been treated with chemicals to remove lignin and other impurities, resulting in a white color. It is used for high-quality printing and writing papers.

    • The stationery is made from fully bleached wood pulp.
  • "Mechanical wood pulp": Pulp produced by grinding wood logs against a stone or metal surface. It contains most of the wood's lignin, making the resulting paper less durable and more prone to yellowing.

    • Newsprint often contains a high percentage of mechanical wood pulp.
Variants and Related Words
  • Pulp (n): A soft, wet, shapeless mass of material. In an industrial context, it often refers to the raw fibrous material from wood, rags, or other sources before it is made into paper.

    • The logs were chipped and cooked into a brown pulp.
  • Cellulose (n): The main polysaccharide constituent of plant cell walls and the primary component of wood pulp, used to make paper, textiles, and plastics.

    • The chemical process extracts pure cellulose from the wood pulp.
Synonyms
  • Paper pulp: A more general term for pulp intended for papermaking, which can be made from wood, cotton, or other fibers.
  • Fibrous mass: A descriptive term for the physical state of the material.
Related Phrases
  • "To pulp wood": The process of turning wood into pulp.
    • The mill uses a thermomechanical method to pulp wood efficiently.
