Abstract/ Executive Summary:

In this year only six grades of jute fibers were studied. The average diameter of different grades of fiber was measured by Air Flow method and Gravimetric method. From the results it has been obvious that white jute fiber is finer than tossa jute fiber are observed from fineness values determined by both air flow method and gravimetric method. To establish a relationship among the test method, further studies are required.

Keywords: Fineness, Bundle strength, Bursting energy

Location: Bangladesh Jute Research Institute

Start Date: 01-01-1997

End Date: 31-12-1998

Program Area: Knowledge Management

Commodity: Jute

Objectives:

To establish the relationships among the test methods-Gravimetric method, Airflow method and microscopic method which are used for the determination of fiber fineness.

Methodology:

This year only six grades each of jute fibers namely, BWC, BWD, BWE, BTC, BTD, and BTE could be procured for this project work. Fineness of the fibers of all grades were determined by Airflow method. Then tex values from the corresponding bundle of each of the different grades of fiber were determined by gravimetric method. In this project, fineness in microscopic method could not be determined due to lack of proper machine facility. A comparison between the results obtained using two methods have been made in order to establish a relationship.

Achievement/Findings:

From the methods used in this work in determining fineness of six different grades of fiber, a multiplying factor has been found out for each of the different fiber grade. From the results it has been obvious that white jute fiber is finer than tossa jute fiber are observed from fineness values determined by both air flow method and gravimetric method. Though all three grades C, D and E of white jute have lower values than the corresponding grades of tossa jute, they maintained no order with the grades within each variety.
