Abstract/ Executive Summary:

It was found that wash fastness of the samples mordants with copper sulphate and ferrous sulphate,nickle chloride and ferrous sulphate indicated signification results.The soaping treatment improved the shade considerably by removing the loose bonded lakes.The rubbing fastness was found to be excellent in respective of the mordant used.Light fastness with magnesium chloride mordant is of a low order copper and iron mordants produced good light fastness.Zinc chloride mordant produces medium light fastness.

Keywords: Desized, Scoured, Bleached, Jute fabrics, Mordant, Green coconut coir

Location: Bangladesh Jute Research Institute.

Start Date: 01-07-1999

End Date: 30-06-2001

Program Area: Postharvest and Agro-processing

Commodity: Jute

Objectives:

To develop methods of dyeing,printing and appropriate process for jute goods.

Methodology:

Desized,scoured and bleached jute fabrics were dyed coloring matters which were extracted from green coconut coir and use some antioxidant chemicals and mordanting agents such Nickle chloride, ferrous sulphate,Copper sulphate,Zinc chloride,Aluminium chloride and magnesium chloride by two bath process.The mordant samples were than immersed into the dye solution of different concentration 50-55 degree centigrade keeping.The M:L ratio 1:20 for 30-60 min.All the dyed jute fabrics were washed with cold water and dried at room temp.Then wash fastness,rubbing fastness and light fastness were measured according to ISO-3 method.

Achievement/Findings:

Bleached jute fabrics were dyed with coloring matters extracted from green coconut coir and mordanting agents.In the process two bath method was followed.The experiment showed that green coconut coir can be used as a natural color source (natural dyes) with copper mordant for producing deep and bright shades of color jute fabrics with very good and good light fastness in comparison to other.
