Abstract
Human being is very much dependant on plant fibres for various purposes. Natural fibres provide many solutions against
general needs of mankind. All fibres cannot be defined as textile fibres. Textile fibres have softness, flexiblity, drapability,
durability properties. Jute is a golden fibre of Bangladesh and it is used for various purposes. For the assessment of
fibre quality of three types of jute fibre e.g. newly released BJRI Tossa Pat-8 (Robi-1), bleached fibre and variety O-9897
were considered for the analysis of physical properties (Reed jute fibre length, Brightness index, Whiteness index, Bundle
strength and Fineness index) and chemical analysis (Cellulose, Hemicellulose, Lignin, Ash content, Fat/Oil content, Oil
content in jute seed, Pectin content and saponification value) under the present study. Some field level morphological
information was taken as quality contributing characteristics. The study was conducted at the Fibre Chemistry
Department, Chemistry Division and Textile Physics Division of Bangladesh Jute Research Institute, Dhaka, Bangladesh
during 2019-2020. The assessment of physico-chemical properties of the variety BJRI Tossa Pat-8 (Robi-1) was blue
seeded with lower percentage of oil content than naturally brown seeded but saponification value was higher, Brightness
(22.04%), fineness (36.26%) and bundle strength (06.20 lb/mg) index were very much comparable to bleached jute
samples using 6% hydrogen peroxide. Cellulose content was 65.68% as well as lignin and hemicelluloses content were
13.95% and 17.94% respectively which were more prominent than O-9897 varieties of jute fibres.
