History
The Echavarría family were the founders of two textile companies, Coltejer and Fabricato, and were also involved in coffee exportation and importation of other goods. In 1907, Alejandro Echavarría decided to import four power looms, which he put to work along with twelve workers in the patio of his coffee-processing plant. This was the beginning of Coltejer. During the Depression era, Coltejer bought discarded looms cheaply from the United States that were brought in on muleback. During World War II, Coltejer was operating some 70,000 spindles and 1,900 looms, employing 4,000 workers in its Medellin plant in addition to those at Envigado. Production
Coltejer's profits increased by a factor of twenty between 1940 and 1949, from 830,000 pesos to 16,520,000. Coltejer has a total fabric production capacity of about 60 million metres, of which 90% is used to produce clothing and 10% is to make home textiles. It is also one of the leading denim producers in Colombia. Coltejer works with 67 exclusive distributors and 77 wholesalers in Colombia. See also
