Abstract/ Executive Summary:

The experiment was conducted in the Laboratory of Fibre chemistry , Physics and Testing Department of Bangladesh Jute Research Institute (BJRI), Head Quarter, Dhaka during 2006 to 2007. For the improvement of Physicco-mechnical properties of jute fibre, some chemical treatments were taken using sodium hypo chlorate. The physico-mechanical properties of chemically modified jute fibre such as bundle strength, fineness/diameter, brightness, whiteness, tex etc. were studied. By increasing brightness, whiteness and decreasing bundle, diameter/fineness, tex of modified jute sample became more soft than original sample. Yarn quality of modified jute fibre was more similar with cotton sample than that of control jute sample.

Keywords: Jute fibre, Physico-mechanical properties, Bundle strength, Breaking twist, Whiteness, Brightness.

Location: Chemistry Division, Textile Physics Division and Mechanical Processing Division, BJRI.

Start Date: 00-00-2006

End Date: 00-00-2007

Program Area: Postharvest and Agro-processing

Commodity: Jute

Objectives:

To investigate Chemical and Physical studies on different samples of jute( Treated with Sodium Hypochlorate) and allied vegetable fibres in order to increase diversified end uses of jute.

Methodology:

The jute fibre of BW-1 was collected from the experimental field of BJRI and the experiment was conducted in the Laboratory of Fibre Chemistry, Physics and Testing Department of BJRI. The middle portion of the collected BW-1 was cut off with a length of 5 cm and roughly cleaned manually. Neither combing nor the scouring was done. The cleaned jute was chemically modified by mechanical agitation in sodium hypochlorate for 15 minutes at different concentration.after that the mixed chemical with jute was heated for 15 minutes at different temperature for each concentration of the chemical. At last the chemically modified jute is dried at room temperature. To solve the slight change of the room temperature the whole process was done in a closed airtight room.

Achievement/Findings:

Most of he spinning mills in Bangladesh are cotton based. For diversified textile uses of jute, cotton based spinning technique may be used for making fine yarn using chemically modified jute fibre. After chemical modification by Na(OCL)3, jute fibre showed the physico-mechanical properties very near about the cotton fibre. Therefore modified jute fibre will be suitable to use in cotton spinning system which is opening up a great scope for the commercial use of our golden fibre.
