Abstract/ Executive Summary:

In 1997 fifteen varieties of white jute fibre (Corchorus Capsularies), and twelve varieties of Tossa(Corchorus olitorius), and fourteen varieties of kenaf (Hibicus cannabinus) have been studied as the work of germ plasm characterization as well as determination of spinning quality by fibre analysis in terms of fiber quality and properties. Comparing to the standard values of white jute all the varieties of white jute are acceptable and spinnable, but the varieties BZ-2, Roxa and Pl-404028 are of comparable lower qualities. Comparing to the standard values of tossa jute are acceptable and spinnable. Comparing to the standard values of kenaf fiber are acceptable and spinnable but the variety Pl-3291 was too fine.This may may be due to oer retting.

Keywords: Physical property, Jute, Kenaf, Allied fibers

Location: Bangladesh Jute Research Institute

Start Date: 01-01-1995

End Date: 31-12-1998

Program Area: Crop-Soil-Water Management

Commodity: Jute, kenaf

Objectives:

To standardize and assess suitability for spinning and evaluation of fiber qualities of the newly acquired jute and kenaf germ-plasm at BJRI through IJO.

Methodology:

In this study fifteen varieties of white jute fibre (Corchorus Capsularies), and twelve varieties of Tossa(Corchorus olitorius), and fourteen varieties of kenaf (Hibicus cannabinus) were used. All the varieties of these species-white, Tossa and Kenaf fibres were produced at JAES, Manikganj through new Germ plasm of IJO and check varieties- CVL-1, O-9697 and HC-99. The fibers were produced under the same Agronomic conditions. Various physic o-mechanical properties of these fibers such as fineness, bundle strength and bursting energy, tenacity etc, were determined through standard test methods and regression analysis. Test work was done in the standard atmosphere of temp.(20 ± 2?) C and RH (65±2)%.

Achievement/Findings:

This was a study of fifteen varieties of white jute fiber (Corchorus Capsularies), and twelve varieties of Tossa(Corchorus olitorius), and fourteen varieties of kenaf (Hibicus cannabinus). The physic o-mechanical properties of fibers determine their performance and suitability for their spinning. It was observed that bundle strength of white jute from 3.62 to 5.02 kgf/mg. All the white jute varieties were within acceptable range because their values fall within standard range (3.05 to 6.44kgf/mg). The fineness of all the varieties vary from 34.5 to 40.5 microns. It was observed that bundle strength of Tossa jute from 3.99 to 5.08 kgf/mg and all acceptable range of tossa standard (3.15 to 7.01 kgf/mg). The fineness of tossa jute varies from 34.5 to 41 micron of all was comparatively lower which was favorable for spinning. It was observed that bundle strength of kenaf fiber from 3.60 to 4.78 kgf/mg. None of the varieties is similar to Bangladeshi Kenaf standard (5.02 kgf/mg). The fineness of all the varieties were from 35 to 43 microns. Thus, with the respect to fiber quality all varieties are acceptable expect the variety PI-329191.
