Lubrication and its necessity in Jute Industry.
Jul 13, 2016

Presented by Suvankar Bej  on 13th July, 2016

Lubrication is imperative for any kind of machines for their smooth functioning, reduction of wear and tear of moving parts and thereby increasing life of the machines. In order to achieve the desired machine performance it is very essential to use correct type of lubricant with recommended or specified amount. The lecture contained details of types of lubricants, machine-wise requirement of lubricant type and their application schedule and also recommendations for appropriate methodology of application of lubricants. 

GLOBAL ENERGY CRISIS: BIOFUEL A WELCOME ALTERNATIVE
Jun 30, 2016

Presented by Dr. Soumya Mukherjee  on 30th June, 2016

Finding renewable alternatives to fossil fuel has become a necessity not only due to the continuous depletion of limited fossil fuel stock but also for the safe and better environment Lignocellulosic biofuel represents promising alternative as they form the major component of any biomass.Jute is a renewable source of biomass. Jute (C. Camsularis) is a lignocellulosic composite natural fibre comprising of Alphacellulose [60.0-63.0], Hemicellulose [21.0-24.0], Lignin [12.0-13.0], Fats & Waxes [0.4-1.0], Pectin [0.2-1.5], Proteins   or   Nitrogenous   matter, etc. [0.80-1.9] and Ash [0.7-1.2]. Attempts are being made to utilize this rich hemicellulosic content present in jute sticks as a source for biofuel production using cost effective  downstream methods.Ethanol from jute sticks will help in boosting the ethanol production to meet the target for 10% ethanol blending in petrol policy by the end of this year.

The presentation was delivered on notions of sustainability of Geotextiles and its application to geotechnical engineering. It was also focused on the latest research activities related to sustainability in geotechnical engineering, including utilization of recycled materials and use of alternate materials and construction methods to reduce carbon foot print. The use of Jute geotextiles in geotechnical engineering was described from the perspective of sustainability with examples.

Manufacturing of Robust Natural Fibre Preforms Using Bacterial Cellulose as Binder
Jun 1, 2016

Presented by Ms. Ipsita Roy, Research Associate, IJIRA  on 1st June, 2016

Bacterial cellulose (BC), produced by aerobic bacteria received ample of attention due to its unique physiochemical properties compared to plant cellulose. BC finds its application in medical, food and textile industries. BC can be used as a binder in the manufacturing of lignocellulosic natural fibre preforms and composites as it has been proven to increase the tensile properties of the mentioned. Natural fibres like jute, sisal, hemp, etc., can be used along with BC as binder to manufacter better quality Green Composites.

An over view of reactive dyes.
May 25, 2016

Presented by Sampurna Chatterjee  on 25th May, 2016

This presentation highlighted on the chemistry of the reactive dyes and its evolution. The use of the poly functional reactive dye helps to reduce the water consumption, salt consumption & also the dyeing cycle time. Simultaneously it also reduces the energy consumption and CO2 emission.

Waste Management in Jute Industry (Factory Side)
May 11, 2016

Presented by Shri Gopal Mukhopadhyay, Technical Officer, IJIRA  on 11th May, 2016

The presentation was made on different types of waste generated in the factory side, causes of generation, standard percentages of waste generation and remedial measures to reduce the amount of waste. It had been also discussed that proper machine maintenance and awareness among the worker may reduce the waste generation.

Better test method than Dry or Wet Sieving to obtain the Opening Size for Geotextile Filter Desig n Purposes
Apr 27, 2016

Presented by Mrs Soumita Chowdhury, Scientist, IJIRA on 27th Apr, 2016

The presentation was made on different test methods for the measurement of opening size of geotextiles and comparison of the test methods supported by experimental data. Hydrodynamic Sieving, Wet Sieving, Dry Sieving, Mercury Intrusion Porosimetry, Liquid Extrusion Porosimetry, Capillary Flow Porometry, Suction, Image Analysis, Bubble Point are the various test methods discussed. It had been concluded that Capillary Flow Porometry is the best method for the pore size analysis of geotextiles.
