ENVIRONMENTAL ASSESSMENT OF JUTE RETTING WATER
Sep 30, 2015

Presented by Atiar Rahaman Dewan on 30th September 2015.

Environmental assessment of jute retting water is necessary to determine the impact of various jute retting processes on the environment. It has also been found that conventional jute retting process causes more pollution than enzymatic retting of jute. The data obtained from the studies have necessitated the formulation of a farmer-friendly and eco-friendly jute retting process.

A comparison between Jute sack and PP/ HDPE sack with respect to Life Cycle Analysis (LCA)
Sep 23, 2015

Presented by Amal Chandra Deka on 23rd September 2015.

The presentation is based on two study report made by IIT, Kharagpur (2000) and IIT, Delhi (2002) to compare Jute sack and PP/HDPE sack with respect to Life Cycle Analysis. Though the two studies differ in their opinions on environmental issues of Jute sack vis-à-vis PP/HDPE sack, it is found that the impact on the environment of jute sack is less hazardous than that of PP/HDPE sack.

Automatic Emulsion Wastage Control System
Sep 16, 2015

Presented by Joyjit Mukherjee on 16th September 2015.

The presentation is based on previous development work done by the speaker with his team in 2012. The development is about reduction of emulsion wastage in softener machine by using sensor & solenoid valve. It is found in mill trial that 50% reduction in emulsion wastage can be possible by using the system.

IJIRA developed Maintenance Management Information System (MMIS) for Jute Industries.
Sep 9, 2015

Presented by Arindam Das on 9th September 2015.

This system based on maintenance management information system of jute industries, with the help of this system mill can analysis the maintenance data of jute industries.

Synopsis of presentation on “Electrospinning of Cellulosic Nanofibers”
Aug 26, 2015

Presented by Dr. Dr. Sandip Bose on 26th August 2015.

Dr. Sandip Bose introduces the concept of electrospinning as a special fibre spinning technology. Explaining the unique features of electrospun fibres and its applications the challenges associated with electrospinning lingo-cellulosic fibres were presented. Electrospinning of sisal, a fibre similar to jute in chemical composition, with trifluroacetic acid and electrospinning of different forms of lignin with PEO as spinning assistant was highlighted. The effect of different parameter on electrospinning was also discussed. A correlation between fibre diameter and power requirement for electrospinning was also drawn.

 

Application of Jute-LLDPE Composites for Consumer's Product Development
Aug 19, 2015

Presented by Ms. Mamata Sarkar on 19th August 2015.

The presentation is based on an exploratory work done by IJIRA with Patton International, Kolkata. The presentation revealed the advantages and scopes of using jute in LLDPE matrix for consumer's product development. The presenter described the use of Kneader Extruder system and rotational moulding system for producing water tank, which shows property improvement by incorporating jute with LLDPE.

De-Lignification of Bamboo By Microorganisms
Aug 12, 2015

Presented by Ms Ipsita Roy on 12th August 2015

Delignification of bamboo has been carried out by two fungi such as, Penicillium sp. and Pythium sp. to separate its cellulose nanofibrils. Isolated fungi have been found to secrete delignifying enzymes such as lignin peroxidise, manganese peroxidise and laccase. Such microbial delignification process for biopulping of lignocellulosics is found to have good future potential.

Designing of new Metallic Card Clothing for Jute Cards
Aug 5, 2015

Presented by Shri Biswarup Nandy on 5th August 2015

The presentation is based on one previous exploratory work done by IJIRA himself collaboration with MILTEX ENG Coimbatore in 2006-2009.IJIRA had explored the possibility of introduction of metallic card clothing in Finisher Card. The presenter has highlighted the positive impacts in terms of quality, cost effectiveness by using MCC over conventional card and meta pin and staves. The presenter also discussed what were the various interesting and learning  experiences and hurdles were been faced during the work and what could be the future road map for successful introduction of metallic card clothing in jute card.

Studies on relationship between Apparent Opening Size (AOS) and Water Permeability of 627 g/m2 Jute Geotextile Fabric.
Jul 29, 2015

Presented by Shri Koushik Das on 29th July 2015

This presentation is based on the sponsored project of National Jute Board. The presentation started with the introduction of Jute Geotextiles, their potential application areas, fabric engineering, standard specifications and design methodology. The porometry of JGT fabric is one of the most decisive parameters for JGT in different application areas. The presentation described the various samples developed under the study and explained various relationships between the constructional parameters and functional properties through regression equations achieved from the laboratory evaluations of the samples.  

Opportunities of Jute Nonwoven in Baghouse filters
Jul 22, 2015

Presented by Shri Partha Sanyal on 22nd July 2015

The presentation has highlighted different mechanism of air filtration and the use of nonwoven in various segments of air filtration. The focus has been given on air filtration for pollution control in large scale industries through Baghouse filters. Detailed components and the mechanism of Baghouse filters have been presented with animated video. The design criteria of Baghouse filter fabric and the required test parameters for the nonwoven Baghouse filter fabric have also been explained during the presentation. The opportunities of jute nonwoven in Baghouse filter fabric have been discussed along with the challenges associated with it.
