Abstract/ Executive Summary:

The research work was conducted at Jute Waste Utilization Department of Bangladesh Jute Research Institute in 1991-92 to determine the effect of rats on geojute. The main objective of the experiment was to attract rats in order to determine their attack on experimental samples. Different types of jute fabrics, cotton fabrics, geojute, thin polypropylene bags and dry fish were used for the experiment. 72 bags of different materials were placed in such a way that all types of materials were equally available to rats. The attraction of rats towards the materials was observed after 3, 7, 15, 30, 90, 120, 180 and 270 days. It is observed that rats have got more or less affinity for jute, differently pretreated jute and cotton fabrics. But it has got no attraction for polypropylene. It is also observed that treatment of jute with copper sulphate and bitumin can reduce the proneness to rats to some extent.

Keywords: Jute, Geojute, Polypropylene, Copper sulphate , Bitumin

Location: Jute Waste Utilization Department, Bangladesh Jute Research Institute, Dhaka-1207.

Start Date: 01-01-1991

End Date: 31-12-1992

Program Area: Postharvest and Agro-processing

Commodity: Jute

Objectives:

To attract rats in order to determine their attack on experimental samples.

Methodology:

Materials: Jute fabrics (A), scoured (B), bleached (C), jute and coir blended jute fabrics (D), grey cotton (E), bleached cotton (F), copper sulphate treated jute fabrics (G), modified geojute (H), modified and improved geojute/geotextiles (I), bitumin treated jute fabrics (J), this polypropylene bag (K) and dry fish were used in the experiment. Above treated and untreated fabrics were used for making 9”/4” bags where dry fish were placed as a bait to attract rats towards the experimental materials. Place of experiment: A sample technique has been developed to place the above materials so that some statistical data can be obtain for harnessing effective results. In all results average of three readings were taken. '-' indicates no indulgence of rats. '+' indicates positive affinity which again quantify the number of pluses by amount of holes made by rats on the experimental bags. The experiment has been continued for long nine months. The data were obtained for different time periods.

Achievement/Findings:

Geo textiles are used in or on the earth. Obviously rats and other vertebrates might have some adverse effect on the geotextiles materials. Jute, geojute, modified geojute etc. are also supposed to have similar effect. The present work was designed to observe the initial behavior of rats towards jute and jute geotextiles products. Cotton and polypropylene materials were also used for comparative study. It is observed that rats have got more or less similar affinity for jute differently pretreated jute and cotton fabrics. But it has got no attraction for polypropylene. It was also observed that modified and improved geojute are also less prone to rats. This might be due to the presence of copper sulphate, Barium carbonate and bitumin in the composite which is used ford the production of improved and modified geojute. Scoured, bleached and untreated jute fabrics have got similar attraction towards rats like grey cotton. This indicates that cellulosic materials have got similarity towards the attraction of rats.
