General view of employee Andrew Roberts operating pulping equipment at a Hercules Powder Company pilot plant in Hopewell, Virginia. This pulping equipment was likely used to produce dissolving pulp, also known as dissolving cellulose, a bleached wood pulp or cotton linters with a high cellulose content. Dissolving pulp derives its name from the fact that, rather than being used to produce paper, it is typically dissolved in a solvent or homogeneous solution and subsequently can be used to create a range of products, including textile fibers, plastics, films, and thickening agents.
Formed in 1912 as part of an anti-trust settlement with DuPont, the Hercules Powder Company (later Hercules Inc.) initially specialized in the manufacture of explosives and smokeless powders and subsequently diversified its business to encompass a variety of industrial products, including pine and paper chemicals, synthetics, pigments, polymers, and cellulose.
