The VGF rayon that began to be sold early in 1900 had relatively coarse yarns of 100–200
denier. Although VGF's product was less versatile than rayon produced by the
viscose process the scale of the operation allowed for reduced prices. Fremery and Urban, with the Alsatian textile chemist David Emil Bronnert (1868–1928), took out two more basic patents in 1900. In 1900, the first year of operation, profits were $15,480. The company set up two smaller plants in Alsace, and in 1903 started manufacturing in
Givet, France. Profits were $422,000 by 1904 and continued to grow in following years. Between 1901 and 1911 the labor force increased to 6.7 times the initial level, and production increased to 16.3 times the initial level. VGF was profitable throughout the period before World War I. Production rose from 86 tons in 1902 to 820 tons in 1912. In 1906 VGF opened a facility in
Sankt Pölten, Austria, and in 1908 opened a plant in
Flint, Wales. , Poland, formerly Stettin It was clear by 1909–10 that viscose, with its cheaper raw materials and simpler spinning process, was economically superior to cuprammonium. In July 1911 the chairman of VGF, Hans Jordan, decided to pay 2 million marks for all the German patent rights for the viscose process and for the Donnersmarcks Kunstseide und Acetatwerke near
Stettin. He planned to fully convert the Donnersmarcks plant to the viscose process. The company headed by Count
Guido Henckel von Donnersmarck (1830–1916) had been the first in Germany to use the viscose process invented by
Courtaulds in Britain. VGF quickly expanded viscose production. Around 1911 VGF began to invest in
J. P. Bemberg, a cloth dying and finishing company that had been experimenting with a version of the cuprammonium process, and encouraged Bemberg to focus on producing yarns for which that process was suitable. Bemberg was using the "stretch-spinning" process invented by the chemist Edmund Thiele (1867–1927) to make cuprammonium rayon with equally fine filaments to the artificial silk of
Hilaire de Chardonnet (1839–1924), and with better physical properties. The VGF product was not competitive. Although Thiele had applied for a patent on his process, a German court ruled on 4 May 1907 that it had been anticipated by the "Pauly" patent. For some time VGF, Courtaulds and the French Comptoir des Textiles Artificiels dominated the
rayon market. Courtaulds became concerned about competition from VGF after the purchase of the Donnersmarck viscose plant, and initiated discussions on ways to avoid harmful competition. VGF and Courtaulds headed a European rayon cartel formed in 1911. Under the 1911 agreements the companies gained domestic monopolies, shared the basic patents and agreed to share future advances made by any of the members of the cartel. The companies planned to form a consortium that would to coordinate sales, set prices and production volumes, and share profits in each region, but were unable to agree on a formal contract before the outbreak of
World War I (1914–18). During the war VGF focused on producing the staple fiber later called rayon, which was spun together with cotton. The German government, faced with a cotton shortage due to the Allied blockade, ordered 3,000 tons of viscose staple from VGF, which was used for a variety of military textiles including clothing. Consumers saw the rayon fabrics as inferior to cotton and associated it with wartime privations. The
Niedermorschweiler plant was destroyed by fire during the war. Germany's defeat in the war cost the company market share both domestically and internationally. ==Weimar Republic (1919–33)==
