Abstract/ Executive Summary:

Jute is a viscoelastic, lingo cellulosic fiber. Physical and chemical properties of all fibrous materials are related to the degree of polymerization, crystallization, and amorphous, proportionality and the fiber orientation. So, the yarn and fabrics properties are related to the structural behavior of these components and their relative positions. In this project structural and physical properties are studied for better understanding of the physico-mechanical properties of raw and modified jute and allied fibers, yarns and fabrics for making valuable products. Different types of white and dyed jute fabrics were collected and chemically treated fabrics were then tested for blending length, crease recovery, thickness, density, whiteness, brightness, density, water absorption capacity using standard method at room temperature and humidity condition. From the different parameters it can be concluded that due to bleaching the whiteness of the white fabrics increased whereas in case of bleached coloured fabrics this value decreased.

Keywords: Physico-mechanical properties, structural properties, water absorption

Location: BJRI, Dhaka

Start Date: 01-01-1999

End Date: 30-06-2001

Program Area: Resource Development and Management

Commodity: Jute

Objectives:

i). To measure the physical and chemical characteristics of jute and allied fiber and fabrics, ii). to improve the textile properties of fiber and fabrics, iii). studies on the morphological structure of raw and modified jute and allied fibers and fabrics and to find out the distinguishing features among the different varieties of fibers and related them to spinning, weaving and dyeing properties of their products.

Methodology:

Different types of white and dyed jute fabrics were collected and chemically treated. The fabrics were then tested for bending length, crease recovery, thickness, density, whiteness and brightness, and water absorption capacity using Presley bundle strength tester, crease recovery meter, thickness meter, microscope, photo volt meter and wettability tester respectively in room temperature and humidity condition using standard methods.

Budget: 10,000/-

Total Budget (Tk.) : 10,000/-

Achievement/Findings:

Different fabrics properties viz. bending length, crease recovery angle, thickness, density, whiteness, brightness and water absorption capacity of different bleached fabrics were determined. Among all the samples it was found that no.15 has highest and no.13 has lowest bending length. Jute fabrics of white colour showed greater whiteness compared to coloured fabrics of different colours. It was also noticed that the fabric having higher stiffness value got the crease recovery value and the fabrics having higher thickness value were stiffer. From the result it can be said that fabrics made from jute flax blended yarn is better than the fabrics made from the yarn of 100% jute in weft and 100% flax in warp and the weave was plain.
