It is a semifinished product in the manufacture of paper, cardboard, and wood-fiber boards. Wood pulp was first produced in the 1840’s by the German weaver F. G. Keller, and it is called white, brown, or chemical, depending on how it is produced. White wood pulp is obtained from wood without further processing; brown pulp is first steamed under pressure in boilers; and chemical wood pulp is made from wood processed by solutions of caustic soda, monosulfite, or sodium bicarbonate (sometimes under pressure and at temperatures of up to 150°C). Wood pulp is widely used because of its low cost in comparison with cellulose or semipulp made from rags and also because of its ability to enhance the printing properties of paper (smoothness, opacity, ink absorption). Among the disadvantages of wood pulp are its relatively low mechanical strength and insufficient whiteness, as well as the inability of these properties to withstand the effects of sunlight, moisture, and heat.
