Textile Chemistry Research and Innovation Center
First elite center of excellence in textile chemistry in Africa
1. Background on Textile Chemistry Center of Research and Innovation
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 research and innovation center under EiTEX, TC-RiC is concerned about professional and research development in the following core disciplines.
- Fibers and Polymeric Materials
- Textile Preparation
- Coloration Technology (Dyeing and Printing)
- Conventional and Advanced Textile Finishing
- Multi-Functional Finishing
- Colour Analysis and Colour Matching
As a purpose in meeting the vision of the institute as per nation demand 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, educational institutions and related sectors. The center is organized to provide well trained textile chemists and researchers/innovators to the market in the fields of textile processing and fiber/polymer science and technology.
With this regard the TC-RiC is striving to support the stakeholders and the nation as a whole supplying transferable knowledge and skills through continuous and effective research and dissemination activities. 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, and academic seminars) 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 growth and transformation plan of the government.
2. Vision of Textile Chemistry Center of Research and Innovation Center
To become one of the three research and innovation centers in textile chemistry in Africa in 2025 recognized for its problem solving and transferable research to the society.
3. Mission of Textile Chemistry Center of Research and Innovation Center
To create suitable environment by which students and scholars scale-up their academic excellence and potentials by involving in fibre and textile processing research and innovation activities and transferring acquired knowledge and skills in a systematic way to large, medium and small scale industries and community at regional and national level.
4. About Textile Chemistry Specialization
Textile chemistry, as a field of specialization in applied chemistry, deals about the interrelation of chemistry with fibrous and textile materials. Textile chemists are highly specialized chemists who apply the basic principles of chemistry to the understanding of textile materials, for the purpose of functionality and aesthetically modifying them into useful and desirable items. Generally speaking textile chemistry encompasses:
- Polymer science
- Fibre science and technology
- Textile Preparation
- Coloration of textiles (dyeing and printing technologies
- Multifunctional finishes for serviceability and functional purpose
- Colour Analysis and Colour Matching
Textile chemists must not only have an in-depth understanding of the structure and properties of natural and synthetic fibers and their polymer make-ups, but they must also be expert in post treatment chemistries which impart aesthetic and serviceability properties such as dyeability, pleasanc, durability as well as be knowledgeable in areas such as recycling, biodegradability and overall environmental concerns.
Textile chemists are expected to work on the following major duties in technical terms:
- Specialist in fibers and cleaning, coloration and finishing of textiles
- Specialist in spectroscopy and chromatography techniques and utilize accordingly for chemical and physical characterization
- Right First Time Dyeing Technologies
- Right first time maintenance of chemical laboratory and write technical specifications for instruments thereof
- Plan and conduct quality tests and conduct process control
- Manage dye and process house at industry and pilot level
Textile chemists are hired in organizations involved in applying the principles of chemistry to the understanding of textile materials, and to their functional and aesthetic modification into useful and desirable items. This include textile industries with finishing sector and academia (universities, institutes) and other government organizations in research, regulatory and policy related roles in the sector. Companies that manufacture basic polymers and synthetic fibers, dyeing houses and higher government agencies are particular organizations with due interest in textile chemists.
5. Rationale of Textile Chemistry Research and Innovation Centre
The textile sector is given a priority manufacturing sector as per the growth and transformation plan (GTP) of Ethiopia. Among the various needs to satisfy the GTP requirements is creating specialized professionals and researchers which support the stake holders (Industries and SME) to maximize their involvement in producing quality products and enhance their involvement in export market globally. With this regard it has become necessary to create specialized professions in universities and allied institutes intended to work on specific research and innovation to address the critical demands.
The Ethiopian industries are not producing good quality finished products as expected in the global market. Along with this the total share of export in the sector is not also as per the expectations. To this end it has become necessary to create specialized professionals and researchers in the area of textile chemistry which enhance the quality of finished products and ultimately will be able to maximize the export share. The first and only research innovation center in Ethiopia, TC-RiC is organized under EiTEX to fill these critical ad timely demands.
This rationale is expected to be implemented by conducting effective teaching learning in textile chemistry, problem solving research and innovation in wet processing, focused transferable technology developments in wet processing, community supporting focused training and related activities and enhance scientific publications and other dissemination activities.
