The rise in farming and the liberalisation of export trade stimulated the traditional wool sector and the paper manufacturing industry, as well as the foundries. They also led to an emerging rural sector that required only a modest initial investment, the printed cotton factories, which restructured the textile industry. These factories were markedly capitalist, with a clear distinction between the owner and the paid employees, who were often peasants. They worked together in the same premises in a mechanised process involving new machinery such as spinning jennies and a locally-developed spinning machine known the Berguedana.
