Abstract/ Executive Summary:

A comparative study was made on Bangladesh Jute Carpet as regards fiber, dye and water used. Jute fibers and yarns (both dyed and undyed) used in different carpet mills were studied as regards dye absorption at different stages of processing along with their tensile strength. Water used in different carpet mills was also studied. Ten different suggestion were sent to BJMC which will be helpful to improve the jute carpet and increase its market potential.

Keywords: Dyeing, Fastness, Jute carpet.

Location: Technology Division, BJRI Technology Wing, Manik Mia Avenue, Dhaka-1207

Start Date: 10-06-1988

End Date: 31-12-1989

Program Area: Postharvest and Agro-processing

Commodity: Jute

Objectives:

1.To improve the physico-mechanical and physico-chemical properties of jute carpet and

2.To increase its market potentiality.

Methodology:

Twenty types of dyed jute fiber and yarn from 4 different carpet mills were procured at different stages of processing and were analyzed as regard dye absorption and fastness properties along with fiber strength. The fastness was measure with standard method followed by ISO recommendation no. 3 and dye absorption was measured by absorption spectrophotometer. Strength was measured by Pressly index. Fourteen different due of different classes which are used in the carpet dyeing in four Jute carpet Mills were procured. The properties of these dyes like affinity, exhaustion, shade, chromophoric groups and structure were determined. Cost and economic aspect of jute carpet production also studied. In this respect of jute carpet production also studied. In another study dyed jute samples prepared by different companies namely BASF, Bayer, ICI were also analyzed in respect to their fastness properties.

Achievement/Findings:

A thorough study as regard to various properties of jute carpet was made. the properties like washing, rubbing, dye absorption, dye affinity, dye exhaustion, structure and shade of the dyes were determined by standard method at standard room temperature and humidity conditions. Ten different suggestions were made to improve the jute carpet and its market potential. and the report of the study was sent to BJMC for necessary action as per resolution of the meeting between BJMC and BJRI .
