The Department of Textile Technology has had a rather interesting history as compared to other Departments of IIT Delhi. It has its roots in the pre-independence days, going back to the year 1942 when the Delhi Polytechnic (now the Delhi College of Engineering) was founded to provide diploma level education. The degree courses were instituted in 1952 by affiliation with the Delhi University. The fortunes of the Textile Department took a sudden turn in 1958 when a high power committee, appointed by the Central Government, decided to establish a new College of Engineering and Technology in Delhi, with British collaboration. This was later to become Indian Institute of Technology Delhi (IITD). It was decided to transfer Textile Technology Department lock, stock and barrel to the new college which started functioning in 1961. The first M.Tech course started in 1967 and the first Ph.D. degree was awarded in 1969, among the earliest at IIT Delhi.
The Department offers one UG program in Textile Technology and two PG programs in Textile Engineering and in Fiber Science & Technology, besides offering the Doctoral program. This department, being the only one of its kind in the IIT system, bears the additional responsibility of providing the road map for the growth of other Textile Institutes in India.
The activities are focused on niche and futuristic areas, such as Smart textiles, Nanotechnology applications, Biotextiles, Engineering of functional apparel, etc. The Global interaction of the department has been improving during the past few years. Close interaction also exists between this department and the University of Bolton, UK and the University of Liberec of Czech Republic, which benefits our students in terms of fellowships and internships as well as faculty members in their research through short term visits. The EU project involves interaction between our students & faculty members and those from EPFL of Switzerland, Uppsala of Sweden, RWTH of Aachen and UC of London in Tissue Engineering. The department also has strong interactions with a Polish Institute (Institute of Natural Fibers, Poznan), an Australian Institute (CSIRO Fibres and Textiles Technology, Melbourne), Italian Institutes (CNR-ISMAC, Biela and POLITECNICO DI MILANO) a Japanese University (Shinshu University, Japan), a Vietnamese Institute (Hanoi University of Technology) and NCSU of USA with whom we expect to develop mutually rewarding activities in the coming years.
The UG program in Textile Technology primarily covers development and characterization of the polymeric raw materials and methods of conversion of the same into textile materials followed by further value addition and appropriate engineering into niche products. Issues related to the management of the production facilities and marketing the products are also covered adequately.
During the first two semesters, the students take courses in basic sciences, engineering arts and sciences, and humanities and social sciences which are common to students of all disciplines. During the next two semesters, the students take a set of departmental core subjects in Textile Technology. From the fifth semester onwards they opt for departmental elective courses. In the new curriculum, there is increased emphasis on design, product and process development activities. In the final year, students are required to work on a project under the supervision of a faculty member. They also undergo practical training in an industrial establishment as part of their overall engineering education.
Two M.Tech. programmes, one in Textile Engineering and the other in Fibre Science & Technology are offered. The Textile Engineering students are trained for mechanical processing of textile materials, while the Fibre Science and Technology students are trained for the manmade fibre industry as also the chemical processing of textile materials. The students are especially suitable for technical services; research and development work in industry.
Current areas of Doctoral and post-doctoral research include study of structure and properties of fibres and fibrous materials, analysis and design of yarn and fabric formation systems, mechanics of production processes, comfort properties of textiles, optimization and mechanism of dyeing and preparatory processes, eco friendly processing, micro encapsulation, antimicrobial finishes, nanotechnology applications, plasma treatment, design of technical textiles, smart and innovative textiles, electroconductive textiles, medical textiles and tissue engineering, polymer composites and apparel engineering.
