Research Program on 'Nanotechnology Applications in Textiles'
The Nano Research Group at Department of Textile Technology, IIT Delhi is working on creating new functionalities in fibers and textiles through use of nanotechnology. Several sponsored research projects have been undertaken, funded by Department of Science and Technology (DST) Govt. of India and Defense Research and Development Organization (DRDO), India, The University of Bolton, U.K.
DEVELOPMENT OF NANO MATERIAL ENHANCED HIGH PERFORMANCE COATED TEXTILES:
The group is also doing a collaborative project funded by a defense R & D organization (ADRDE) for development of Polymer/Clay nanocomposite coated fabric for application as inflatable. This fabric not only has enhanced ability to retain gases, at a lower mass, but also has improved tensile and tear strength and resistance to weathering.
Polyurethane-Clay Nanocomposite for Inflatables
- Funded by Defense Research and Development Organization (DRDO), India
- Breaking strength
- Tearing strength
- Elongation at break
- Thermal stability
- Gas barrier property to H2,He
- Funded by Department of Science and Technology (DST), Govt. of India under Nanoscience and Nanotechnology Initiative
Nanocomposite vs Neat Coated Fabric show improved -
Nanomaterial enhanced High Performance Coated Fabric
The aim of this project is to develop high performance coated fabrics for use in advanced technical textile applications such as Defense, Automobile, etc. The use of nanoparticles in coatings provides a range of possibilities of imparting specific functionalities to textiles such as Antimicrobial, Flame Retardant, Self-Cleaning, UV protective/Resistant, Gas Barrier and Stain Resistant
BIOACTIVE AND FUNCTIONAL TEXTILES:
Bioactive Textiles based on ecofriendly chitosan and silver in nanoform are being researched for their potential application in protective clothing against biohazards and other medical applications i.e. sutures, bandages, wound dressings etc.
