Alvan Sabet Knowledge-Based Company was established in 1983, 45 km from Hamedan city on the Hamedan-Tehran road, as the largest synthesizer of dyes and chemicals in the Middle East, covering the textile and leather industries, and was put into operation in four groups: acid, direct, reactive, and pigment paste textile dyes in 1996.

Then, in 2004, by upgrading the technical knowledge of production and attracting experienced experts, the quality of the products was upgraded to international standards and annually supplies more than 100 types of acid, reactive, direct dyes, pigment paste, and cooperative materials for textile, leather, and paper to countless customers throughout the country and some neighboring countries.

Also, this company, considering the need of the country’s oil refineries for gasoline dyes and petroleum products in order to achieve self-sufficiency of the country, has started to produce and supply the major dyes used by all refineries in the country after obtaining quality approval from the Petroleum Industry Research Institute.
