Abstract/ Executive Summary:

The experiment was conducted during the year 2001-2003 at Jute Waste Processing Department of Bangladesh Jute Research Institute.The project was taken for diversification of jute waste by making felt as well as covering as several absorber and heat insulator. For this purpose, 7 samples of different thickness single and double punched layer were produced by using chemically modified jute caddies and thickness dependence of thermal conductivity was estimated.It was found that chemically modified jute caddies were produced felts to find diversified uses.

Objectives:

Preparation of quilts and mattresses with chemically modified jute waste for people of low income group of Bangladesh. Industrial and diversified use of low quality jute and jute waste for manufacturing cost effective products.

Methodology:

Jute waste were collected and scoured with mild alkali and wetting agent at a room temperature of 80⁰C for an hour. The blending were carried out with hydrogen per oxide. Treated samples were carded and felts of different thickness were made by needle punching method. We have already studied the absorption time of seven different felts by wettability method and thermal conductivities were estimated by electrical method. The felt thickness were measured under a constant pressure.

Budget: 25,000/-

Total Budget (Tk.) : 25,000/-

Achievement/Findings:

The absorption time of the samples were measured at a relative humidity of about 70%±5% and at a room temperature of the sample. For these purpose, Seven samples of different thickness were produced by needle punching method and were proved as sound absorber, which was used in the Auditorium of Bangla Academy.
