17th and 18th centuries

In 1700, the capital of the Chartreuse massif and its surrounding area had about 1,200 inhabitants and more than a hundred of them worked in the processing of hemp.

Since the beginning of the century, production had been organized around the Voironnaise factory and canvases were marked to certify their origin. The city acquired a great reputation thanks to its paintings resulting from a secular know-how. The privileges granted by Louis XII disappeared during the French Revolution. However, the production of canvas continued, and their reputation allowed Voiron to maintain this activity under the First Empire due in large part to purchases by the army.

19th century

The nineteenth century saw the decline of the era of canvas in Voiron because of the scarcity of linen and cotton, and because of the disappearance of the sailing navy which had been a large consumer of canvasses. Voiron came to be known for its fine silks, sought after by European royalties. Voiron then benefited from a female workforce, housed at the factory and often poorly paid. Voiron also gained religious influence marked by the 1876 erection of the Saint-Bruno church of neo-Gothic style^{[clarification needed]} by a first magistrate. A statue representing the Virgin Mary and the infant Jesus, a tribute to Notre-Dame-de-France Puy-en-Velay, was also erected.

20th century

The company Skis Rossignol was founded in 1907 by Abel Rossignol. Entire families of Voiron, along with Italian immigrants who arrived en masse at the beginning of the century, worked in these factories.^{[citation needed]} On the eve of the First World War, the silk-weaving business used nearly 3,000 looms. At the same time, the rise of paper mills on the banks of the Morge, the river crossing the small town, attracted workers to the city. The company Radiall was founded as well and the population of Voiron grew past 15,000.

21st century

Voiron remains a significant economic and administrative center of the department of Isère. Voiron has sought to keep its independence from its much larger neighbor, the Grenoble conurbation. Voiron survived a difficult conversion after the departure of companies Rossignol and Johnson & Johnson. Pays Voironnais is working to attract new jobs aimed at limiting the dormitory phenomenon already affecting the suburbs of Voiron.^{[clarification needed]} However, because of the urban sprawl between Voreppe and Voiron, this town has been considered by the National Institute of Statistics and Economic Studies (INSEE) as belonging to the Grenoble-Alpes Métropole since 2010.
