Abstract
There are so many fibres, but not all of them are textile. Textile materials are generally soft, flexible, and capable of being transformed into desired shapes without resistance and durable over a reasonable period of wear. Jute –the Golden fibre of Bangladesh is used widely for various purposes. For the assessment of fibre quality of three types of jute fibre e.g. newly released jute variety-72, 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 safonification value) under the present study.Some field level morphological information was taken as quality contributing characteristics. The study was conducted at the Chemistry Division, Textile Physics Division and Pilot Plant and Processing Division of Bangladesh Jute Research Institute, Dhaka, Bangladesh during 2017-2019. The assessment of physico-chemical properties of the variety O-72 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.
Highlights
Jute is a major textile fibre and a raw material for non- traditional and value added non-textile products
The matured jute fibre of the variety O-72 was collected from the Agricultural Wing of Bangladesh Jute Research Institute (BJRI)
The present study focused on the physico-chemical properties of newly released jute variety O-72
Summary
Jute is a major textile fibre and a raw material for non- traditional and value added non-textile products. The usual composition of chemical constituents in jute fibre is alpha cellulose (58-63%), hemicellulose (21-24%), lignin (12-14%), wax (0.4-0.8%), pectin (0.2-0.5%), ash (0.6-1.2) and traces of other coloring materials [1]. For upgrading the jute fibre different types of chemicals and finishing treatment has been carried out but it is very costly. Jute fibres are lignocellulosic [3] and the secondary walldevelopment of the sclerenchymaticfibre cells involves deposition of lignin over the cellulose matrix [4,5]. Presence of lignin in the fibre cell wall makes it impermeable andresistant to microbial degradation [6]. Based upon the information [11,12,13,14]for increasing whiteness andbrightness of jute fibre different bleaching treatments have been carried out. Present work indicates to find out an improved jute variety which will bemostly comparable with the bleached jute fibre
