 Technological Research on JAF crops
Bangladesh Jute Research Institute

Bangladesh

BJRI has a wing carrying out technological research on Jute & Allied Fibre (JAF) crops. The main achievements in this field are:

• A process for the production of blankets from jute-acrylic blend was developed by BJMC and BJRI. To commercialise the process a Memorandum of Understanding (M.O.U.) has been signed recently between BJRI and Grameen Uddog.

• Commercial processes for the production of the following home-furnishing fabrics were developed: jute-cotton union fabrics, jute-synthetic union fabrics, wall covering with jute fibre.

• Technologies for the production of jute products such as school bags, fashion bags/ladies bags, shopping bags, hold-alls, prayer mats, and shoe and sandal cloths were developed, and a M.O.U. has been signed between BJRI and Grameen Uddog.

• Chemical processes for the production of cellulose derivatives such as Microcrystal cellulose (MCC), Carboxymethyl cellulose (CMC), oxalic acid, cellulose acetates, cellulose nitrates and activated charcoal from jute and jute wastes have been established. The process for the production of MCC has been leased out to BEXIMCO. A M.O.U. has been signed between BJRI and Kamrul Engineering and Trading for commercial production of CMC. 

• Scientific grading of raw jute fibres (both White and Tossa varieties of jute) was developed through determination of the chemical indices such as cellulose, lignin, copper number, acetyl content, ash content and nitrogen content.

• A method was developed to blend chemically modified jute with other fibres. The technology has been transferred to the Jute Textile Product Development Centre (JTPDC) of BJRI for pilot scale production.

• Methods to produce various cloths and garments from chemically modified jute blended with cotton, rayon, acrylic, polyester and silk were developed. Pilot scale production at the JTPDC was carried out.

• Easier methods to determine the conductivity of jute and textile materials were evolved.

• A process to determine the fibre length of jute based on Dollop weight and Doubling process was developed.

• Methods for preparing felts from jute and jute wastes were developed.

• Processes to prepare different yarns and fabrics by using natural and synthetic fibres in admixture with jute were developed.

• Different processes were developed to improve and simplify the processing techniques of the jute industry.
