    Abstract:

Applications: Ramie plant is easy to grow, can be harvest every 45 days of plantation from the second years onwards for 16 years. The fiber has important properties like antimicrobial activity as well as strength but its but still has a very small share in the global natural fiber market. Its price (USD 1.5 per kg) is comparable to cotton lint (USD 1.7 per kg) (as per 2013 document), requirement for production is minimal, yet market application is negligible. As per 2012 data Ramie forms only 1percent of the global non-wood plant fiber production while cotton (84 percent) and Jute (11 percent) dominate the market. This is mainly because the downstream processing of the fiber involves substantial chemical use. The fiber produced is coarse with matt finish and hence is mostly suitable for furnishing, carpets, wall hangings, etc. The current technology improves the fiber quality post degumming and increases its potential for application in finer fabrics with minimum environmental damage.
Advantages: This process of microbial degumming of Ramie fiber produces strong, soft and lustrous fibers when processed for 48 to 72 hours at room temperature with the enzyme combination following partial chemical treatment. The process is eco-friendly (less toxic), produces better quality of processed fiber, hence enhancing the scope of its wider application.

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.
