The research work was carried out at Chemical Processing Department of Bangladesh Jute Research Institute in 2008 . The project was taken to improve the brightness and whiteness property of the fibre. Jute fibre were treated with four different types of acid (formic acid, acetic acid, oxalic acid & citric acid) and a weak alkali (ammonium hydro oxide) in different concentrations of the solutions such as 1gm/l, 3gm/l, 5gm/l, 7gm/l and 10gm/l. Different parameters were measured. Jute fabric treated with 10gm/l citric acid solution gives the best brightness & whiteness property for jute fibre.

Development of new technologies for improvement of glassy and brightness property of jute fibre. It will be increase the diversified uses of jute fibre.

Jute fibre were treated with four different types of weak acid (formic acid, acetic acid, oxalic acid & citric acid) and a weak alkali named ammonium hydro oxide. Four different concentrations of the solution such as 1gm/l, 3gm/l, 5gm/l, 7gm/l and 10gm/l were prepared for each acids and alkali. Jute fibre were treated with this chemicals for 30 min. and dry in the open year. After treatment, the bundle strength, fineness, whiteness (%) and brightness (%) of the samples were measured in the testing lab. The pH of the solution was determined.

Among five chemicals, brightness & whiteness property of jute fibre increases with acid treatment and decreases with alkali treatment. Jute fibre treated with citric acid in 10gm/l solution achieve (brightness 38.90%, whiteness, 38.75%, bundle strength 9.640lb/gm and fineness 35.5µ) the highest quality for jute fibre. This will increased the market potentiality both in the domestic an international market of raw jute.
