Rapier Loom Tenders for Bahir Dar Polytechnic Institute
Contents
Tenderer
The Bahir Dar Polytechnic Institute, which has now evolved into Technology and Textile Institutes, was founded in 1963 via technical collaboration between the Government of the Soviet Union and the Imperial Government of Ethiopia. The institute was a prominent producer of technicians for the nation. The institute began its first training program in Textile Technology at the advanced diploma level in conjunction with the Russian Government under the name Bahir Dar Polytechnic Institute, which later became Bahir Dar University in 2000. For almost 33 years, the training program was at the Advanced Diploma level in the subject of textile technology. The Advanced Diploma program was then elevated to a B.Sc. degree in Textile Engineering in 1997.
