The extended nature of industrial operations demanded the integration of information and communication technologies (ICT) and computer aided technology (CAx) in industrial processes. Although there are 130 textile and apparel industries in Ethiopia, the adoption of such technology is limited. Hence, this research studied factors affecting CAx adoption through the extension of the technology acceptance model of Davis (1989) by adding perceived competitive advantage, cost effectiveness, and perceived security. The finding revealed that perceived ease of use, perceived service, perceived competitive advantage, cost effectiveness, perceived security and perceived usefulness are significant predictors of intention to use CAx in textile and apparel industries.
