Textile Chemistry Research and Innovation Center

Profile of Textile Chemistry  Research and Innovation center

  • Background

The center of research and innovation for textile chemistry (TC-RiC) is one of the research and innovation centers in Ethiopian Institute of Textile and Fashion Technology, EiTEX. The center is established in the year 2011 and is among the four pillar research and innovation centers in EiTEX.

As a purpose in the institute the TC-RiC is launched among other development programs to excel in research, innovation and dissemination activities aimed at providing efficient support to the textile industry and related sectors. The center is also engaged providing effective textile technologists/engineers/chemists to the market in the fields of wet processing and fiber science and polymer technology.

With this regard the center supports the stakeholders and the nation as a whole supplying transferable knowledge and skills through continuous and effective research. On the spot at the ground the TC-RiC is engaged on ensuring quality teaching-learning process, problem solving and transferable research and training and outcome based dissemination (technology transfer, community service, scientific publications) activities. These activities are in line with the stetted missions and vision of the institute cascaded from the expectations of the sector as per the plan of the government.

  • Lab/workshop

The textile chemistry center of research and innovation has variety of instruments arranged in seven laboratories and also standard stores for chemicals and fabrics and other supplies. Most of the instruments are from highly recognized commercial suppliers including PerkinElmer, textech, SDL and other. The laboratories arranged as per KAIZEN principles and the usage and utilization of resources in each lab is governed by the laboratory management system.

In addition to the well equipped laboratories with high grade instruments we have integrated workshop includes different machines for production of pretreated dyed and finished goods in mass production.
