In the industrial age Delmenhorst experienced great economic growth, thanks to Bremen. Since Bremen was in a different duty zone, merchants who wanted to export manufactured goods outside of Bremen had to pay high customs duties. They therefore only exported the resources and produced their commodities in the surrounding villages. The industries arising were the "Jute" - a spinning works and weavery in 1871, the "Delmenhorster Linoleumfabrik" - a linoleum factory, in 1882, the "Norddeutsche Wollkämmerei und Kammgarnspinnerei" or "Nordwolle" - another, bigger spinning works, and several others. The number of inhabitants quadrupled in these years.
