Abstract/ Executive Summary:

The physical properties of a woven fabric, such as thickness, weight, texture, handle etc and its performance characteristics such as resistance to abrasion, tearing, creasing, laundering etc depend on yarn characteristics, spacing and interlacing as well as finishing of the products. Experimental of this project contained the finding of different physical characteristics of jute fabrics. The experiment was limited to finding out the strength, stiffness, luster, count etc of jute fabrics produced in different jute mills of Bangladesh. In the present project different physical character viz strength, stiffness, luster, counts etc of 20 samples of new Improved Australian Wool pack Produced in Crescent Jute Mills, Platinum Jute Mills and Adamjee Jute Mills were studied and reported in tabular from during 1980 in the physics department of BJRI.

Keywords: Tearing strength, Instron, Flexural rigidity,Australian wool pack

Location: Physics Department, Physics and Testing Division, BJRI, Technology Wing, Manik Mia Avenue, Dhaka-1207.

Start Date: 01-01-1980

End Date: 30-06-1980

Program Area: Postharvest and Agro-processing

Commodity: Jute

Objectives:

To study the physical character of jute fabrics of different construction and weight collected from different jute mills of Bangladesh.

Methodology:

For measuring the strength of fabrics, strips of fabrics of sizes 2 by 8 inches were fixed between the jaws of an Instron and the tearing strength were obtained from the graph. Stiffness means resistance to bending or flexural rigidity i.e. the couple on either end of a strip of unit width bent into unit curvature in the absence of any tension. A strip of fabrics of size 1 by 6 inch was slid in a direction parallel to its length so that its ends were projected from the edge of a horizontal surface. The length of overhang was measured when the tip of the test specimen was depressed under its own weight to the point where the line joining the tip of the platform made an angle of 41.5 degree with the horizontal. One half of this length was the bending length of the specimen. The cube of this quantity multiplied by the weight per unit area of the fabric gave the flexural rigidity.

Achievement/Findings:

In the present observation some samples of Platinum, Crescent and Adamjee were studied. But unless the fabrics of desired constructions and weight can be manufactured a comparative study of different fabrics is not possible. Moreover there was no facility for measuring all the characters of the fabrics. No conclusive remark made before collecting data for all the samples.
