1883 Johann Müller-Wullschleger passes away. His widow continues to run the small business, after 1887 together with her son Johann Paul Müller (who will be the founder of the modern dyeing and knitting mill). He will later affiliate a yarn  bleaching and dyeing mill to the cotton fabric printing mill. The printing mill will be closed in the 1920s due to the crisis in the manual weaving business.
1892 Relocation of the business 300 meters southward  to its current location, near which source is located. This source is crucial for satisfying the high water needs of the newly affiliated dye house. The dyeing factory can be expanded thanks to the increasing mechanization of the weaving industry which in turn is responsible for a continuously increasing demand for highly colored cotton. In 1892, Johann Paul Müller marries Marie Kunz who had been born in the U.S. and returned to the village of her parents.  In the following years, she gives birth to a total of 11 children.
1899 Conversion of the yarn dyeing process from manual operation to machine dyeing. At this moment, the company employs 40 staff members. Acquisition of the first steam engine, one of the first mercerising machines and the first bleaching system. There are already specialties such as indigo blue, Turkish red, aniline black and oxidation diamond black. Such specifically finished textiles as well as mercerized cotton yarns are exported to British India, South-east Asia, the Philippines and Turkey.

1927 After long years of extremely high commitment to the family business, Johann Paul Müller reduces his acitivity in the business for health reasons and transfers the management of the company on his six sons. It follows a transformation into a family company under the name “Johann Müller Aktiengesellschaft – Färberei und Strickerei”, where all 11 children are involved. The company occupies 310 employees at this time.
1939 Because of staff shortages following the outbreak of World War II and the steadily growing business, a branch operation opens 1939 in Wohlen. Here in the center of the straw industry, enough manpower for the further expansion of the knitting, hosiery and confection can be found.

1950 A more extensive exhaust gas cleaning equipment for the boiler house is put into operation. By that, not only the pollutant emissions are reduced drastically since 1950, but also heat energy is recovered. The sulfur dioxide emissions causing acid rain can be reduced to 1 / 100 of the legal limit in Switzerland.
