In 1792 J. P. Bemberg changed the business to selling Indigo, a red dye, oil, cotton, linen and wool.

He married Maria Theresia Scheibler (1774–1843) and they had a son, Julius August Bemberg, and two daughters.

It was one of the first companies to engage in mercerisation of cotton yarns and fabrics, and for a long time was a leader in this field.

[3] J. P. Bemberg began to produce artificial textile fiber commercially using the cuprammonium process in 1897.

[2] In 1901 Dr Edmund Thiele developed a stretch-spinning system for J. P. Bemberg, which began to produce fine-filament artificial silk under the Bemberg® trademark in 1908.

Costs were higher than with viscose rayon due to the need to use copper salts and cotton for the cellulose.

However, the global economic crisis forced closure before production had ramped up, and in the end the plant remained unused.

[15] The Dutch firm Nederlandsche Kunstzidje (Enka), VGF and Bemberg remained distinct legal entities owned by AKU as a holding company.

[24] American Bemberg increased production during World War II, and made parachute cloth.

Early in 1942 the Office of Alien Property (OAP) took control of the Elizabethton plants, but did not seize the assets due to the Dutch ownership of the AKU holding company.

[22] In 1947 AKU transferred all rights in both plants to the OAP, and in December 1948 they were sold to Beaunit Mills of New York.

[25] The Bemberg plant was in serious financial trouble by the early 1970s, and could not comply with demands to reduce toxic waste emissions from the United States Environmental Protection Agency.

[11] Asahi Kasei started operations at the newly built Bemberg factory in Nobeoka in 1931, and made its first shipment on 27 June 1931.

[27] By May 2011 Bemberg SpA was insolvent and the city of Gozzano was struggling to find purchasers for the real estate and machinery.
