Banana Fibre - An Overview
Jan 27, 2016

Presented by Mr. Koushik Das on 27th Jan, 2016

Banana is a well known horticultural crop grown for fruit all over the world. Banana pseudo-stems are dumped as waste at the farm level in India due to disposal problem. The  fibre has similar properties like jute, mesta, coir etc. and also attains some extra advantages like low density, appropriate stiffness, high disposability and bio degradable. It can be processed in jute spinning system to produce various technical and diversified yarn or fabrics. The fibre may provide livelihood to poor farmers by using as a various diversified product like handicrafts.

Development of Jute Based Composite Material using Unsaturated Polyester Resin
Jan 20, 2016

Presented by Dr. Md. Safikur Rahman, Deputy Director, IJIRAon 20th January 2016.

Production procedure of jute fibre reinforced thermoset composite using jute in different forms was presented. Jute in the form of cut jute fibre and non-woven was as reinforced. It was observed that jute non- woven is comparatively appropriate for making composite.

Root Cause Analysis of Quality Deterioration of Jute Fibre
Jan 13, 2016

Presented by Mr. A. K. Nandi on 13th Jan, 2016

The presentation discussed about the present status of Raw Jute production (quality wise), domestic and overseas market scenario. It also covers rice and wheat production trend along with jute to estimate the domestic demand. The focus has been given on retting of jute and inferior quality fibre production due to scarcity of water. In order to grasp the export and jute diversified product market it is essential improve quality retting technique with a lesser amount of water.

Studies on Estimation of Threshold Breaking Strength Required in Warp-way, Weft-way and Seam Direction of Jute Bags of Specific Capacity
Jan 6, 2016

Presented by Mr. Palash Paul on 6th January 2016.

A technical presentation was made by Shri Palash Paul, Scientist IJIRA on his recent work on “Studies on Estimation of Threshold Breaking Strength Required in Warp-way, Weft-way and Seam Direction of Jute Bags of Specific Capacity”. The project was jointly sponsored by the National Jute Board and Indian Jute Mills Association. Shri Paul mentioned in his presentation that the project team followed three-way approaches; kinematics, drop test and stress-strain analysis to determine minimum breaking strength required in three major directions of a standard B. Twill jute bag. The study concluded that minimum requirement of warp-way, weft-way and seam direction breaking strength of a standard B. Twill bag is 100 kgf, 100 kgf and 37 kgf respectively with standard specimen size and test parameters.

Surface modification of Jute fibre for improvement in interface characteristics of composites
Dec 30, 2015

Presented by Mr. Debkumar Biswas on 30th December 2015.

Interface characteristics of a composite play vital role in determining the property realization of the ultimate composite products. Natural fibre reinforced both thermoset and thermoplastic composites have often represented issues of incompatibility between matrix and reinforcement due to their dissimilar functional characteristics. Over the years different approaches have been taken to enhance interfacial adhesion among natural fibre based reinforcing materials to polymeric matrix. The presentation envisages a comprehensive summary of developments in this direction.

IMPROVEMENT IN PRODUCTIVITY AND QUALITY OF JUTE BAGS
Dec 23, 2015

Presented by P K Choudhury on 23rd December 2015

Importance of Sack Sewing and Finishing Deptt. in the jute mills has been much realized by the industry in 1980.This is a highly labor intensive and low productive area. As desired by the expert committee and requested by jute mills IJIRA undertook the first project of its kind in the same year on improvement of productivity in bag manufacture. IJIRA ‘s recommended methodology in this regard for  replacing overhead sewing system by Herakle was accepted and adopted by the industry which brought revolution to this sector where production was increased by about 500%.

 Since then IJIRA has been doing extensive R & D work for this sector and came out with success. Many of them have been implemented by the jute mills. Few of such important works are worth mention like ,improvement of seam strength, methodology of calculating seam strength, development of hemless bag, introduction of  combined herakle  & safety sewing m/c, conceptualize on development of automatic bag making machine, development of 50 kg carrying capacity food grain jute bag etc. Various methods were also devised for improving quality and reduction of wastes in sack sewing and finishing sector of jute industry.

BIODIGESTER TECHNOLOGY.
Dec 16, 2015

Presented by Dr. Lokendra Singh on 16th December 2015

Biodigester technology has potential to eliminate wide-spread pollution resulting from untreated human excreta and making India cleaner, fulfilling the aspirations of the nation towards 'Swachh Bharat'. The currently publicized making of pit-toilets in rural setting needs to be looked into from the perspective of wide spread ground water pollution that will result from such toilets in near future. The faecal containing watery matter is likely to percolate further down from the pit and may be drawn in the drinking water through nearby hand pumps or bore wells. It is known that consumption of faecal contaminated water invites a plethora of diseases. Thus, by adopting a time tested sustainable and indigenous technology of biodigester, safe "disposal" of human waste is ensured. This will contribute towards a safer and healthy environment of the country. 

Auxetic Textiles: Concept & Applications.
Dec 9, 2015

Presented by Dr. Mahuya Ghosh on 9th December 2015

Auxetic textiles, a category of new generation textiles, are non-conventional materials having Negative Poisson’s Ratio (NPR). Auxetic textiles can be manufactured from auxetic fibres /or auxetic yarns /or adopting normal fabric formation technologies (warp and weft knitting, weaving) employing normal yarns but adopting special constructions. These textile materials have many enhanced properties, e.g., high shear resistance, high indentation resistance, Synclastic curvature, fracture toughness, energy absorption properties, variable permeability, high volume change, etc. Evidently, this group of textiles has diverse and wide spectrum application potential starting from protective textiles, medical textiles up to aerospace applications.

Process and Quality control in jute spinning by using statistical technique.
Dec 2, 2015

Presented by Mr. Debiprasad Gon on 2nd December 2015

Presentation contains various statistical techniques employed to maintain quality of products in a continuous process from Batching to Spinning

Broadly, this involves the application of various techniques and services to optimise the product quality to ensure the connotation of quality as fitness-for-use'. The quality assurance would mean optimisation of quality within given sets of constraints. These constraints, apart from functional limitations, may be related to mechanical capabilities, human skills etc. However, the constraint of cost is almost universally present in this problem of optimisation.

Second part of the presentation includes on assuring quality in yarn production, quality has to be considered with due importance right from the raw material to the finished product i.e. yarn. Basically, each production position can be considered as a potential source of disturbance. The success in preventing the yarn quality downgrading depends not only on the right selection of raw fibre quality but also much on monitoring of each processing stage to ensure an early recognition of faulty running production process and undertaking of the corrective measures to eliminate the faults or to minimise their intensity.
