Nanofinishing of Jute with Titania
May 29, 2015

Presented by Dr. Sandip Basu on 29th May, 2015


Nanofinishing jute with titanium dioxide helps to impart multiple functional properties like ultra-violet protection, superhydrophobicity, antibactetial property, soil repellant property and photo-oxidative self cleaning property. Sol-gel synthesis of titania, application method of in-situ nanoparticle formation, mechanism of action of nanoparticle and functional property characterisation was discussed in the presentation.

May 20, 2015

Presented by Shri Ritwik Chakraborty on 20th May, 2015

The content of the lecture was the sources and chemistry of natural colorants along with benefits and limitations of natural dyes for textile applications. The presentation also elucidated details of R&D work carried out at IJIRA on selected natural dyes of North - Eastern Region. These included identification of dye-yielding natural resources, extraction of dyes, coloration of textiles with extracted dyes and characterization of dyed materials.

 

Transmigration of Mineral Oil Hydrocarbon (MOH) in Food Items in Packaging
May 13, 2015

Presented by Shri Sakshi Gopal Saha on 13th May, 2015

The transmigration from jute batching oil treated jute bags to packed food items may result in increased level of MOH in food products. Transmigration of MOH may take place by direct contact and/or vapour migration and condensation. In this regard IJO 98/01 limits the use of mineral oil for processing of jute goods meant for food item packaging. IJIRA is undertaking a study to quantify the extent of transmigration from jute bags to food items, if any, in association with Indian Institute of Toxicological Research, Lucknow. IJIRA has developed a rice bran oil based eco-alternative lubricant for jute processing. Currently 17 jute mills are using this technology for manufacturing of food grade jute bags.

The 1st weekly Technical presentation held on 6th May 2015 on “Development of Flax Non-oven for Air Filtration” by Shri Palash Paul.Development of Needle-punched Nonwoven Fabrics from Flax Fibers for Air Filtration Applications
May 6, 2015

Presented by Shri Palash Paul on 6th May, 2015

The technical presentation explained the developmental work carried out by Prof. Rajesh D. Anandjiwala and Prof. Lydia Boguslavsky of South Africa, published in Textile Research Journal in 2008. Different types of needle punched nonwovens were prepared from waste Flax fibre by varying machine and process parameters. The effects of various process parameters on air filtration parameters were studied. The researchers found that multilayered flax nonwoven treated in hot calender at 80oC with some pressure provides the best nonwoven for domestic air filtration application.

Interaction with a Group of Researchers from S. N. Bose Institute led by Prof. A. K. Raychaudhuri, in the presence of Dr. Subrata Gupta, IAS, Jute Commissioner & Shri D. C. Baheti, Chairman, IJIRA.
