    Abstract:

Applications: Wet processing of textiles is a severe environmental threat as it produces wastewaters rich in various toxic chemicals like synthetic dyes, dispersing agents, metal mordants and surfactants. It is very important to find alternative and renewable sources of chemicals that can clean-up environmental pollution. Replacement of synthetic dyes by natural colorants extracted from various plants is an area of interest because they are with eco-friendly, biodegradable and have low risk for human health and environment. An even more economical and environment friendly approach to cultivating such plants is using the by-products and wastes generated from food, timber and agricultural sectors such as berries, skins, shells, peels. In pineapple products processing, pineapple residue accounts for 30-42% of the pineapple processing wastes, usually discarded as a by-product which is a cause of waste of resources. In the current scenario it is important to take full advantage of the processing and pineapple residue. The current technology explores pineapple waste fruit top extract as the medium for acid dyeing and as a potential multifunctional natural dye source for wool fabrics. The process involves precipitation method in which flavonoid dyes present in pineapple fruit tops are allowed to undergo chemical reaction via chelation with Al (III) and Fe (II) metal salts. This method successfully demonstrated the potential of modified dyestuff to produce colorful, antioxidant and antimicrobial wool fabric. The dye also imparted good antioxidant and excellent antimicrobial effect against both S. aureus and E. coli. Application: 1. Medical garments 2. Sanitary garments 3. Military garments 4. Napkins and disposable wipes 5. Socks 6. Carpets
Advantages: 1. This method provides inexpensive multifunctional textile dye 2. This method is feasible alternative for synthetic agents in development of protective clothing. 3. Wool fabrics were imparted potent anti-bacterial property 4. Wool after dyeing with obtained colorants includes anti-oxidant effects 5. It is substitute of acidic dyeing medium for wool fabrics

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
