Topic of Research Proposal : Development of a Novel garments dyeing process by using

Natural dyes

Background on the Research Topics:

Natural dyes have become a part of human life since immemorial time. Currently there is a

re-introduction of natural dyes which, compared with synthetic dyes, exhibit higher

biodegradability, environmental compatibility, lower toxicity. The main focus of the research

proposal is the study of natural dyeing process with the aim of improving natural dyeing in

garments stages.

Natural (plant-based) dyes are regaining some importance in the textile coloration industry.

There are strong recommendations to re-instate them to the status of key ingredient rather

than being relegated to the use by hobbyists or rural craftsmen. This may be attributed to the

current and impending problems associated with synthetic dyes. The environment conscious

informed customer and fashion are the other driving factors. This change has prompted

research in the arcane art of dyeing with natural colors on a modern industrial scale. Cotton

remains the king of textiles and has been taken as the material of choice.Early records have

guided the hobbyist to use exhaustion from water as the standard method for dyeing with

natural dyes. It also recommended using metallic salts to alter the color and or to improve

desirable characteristics.

Today, when the process is promoted on an industrial level a reduction in water consumption

and elimination of metals becomes necessary. The purpose of this research is to examine and

evaluate alternate methods of coloration, presently used in coloration with synthetic dyes,

which will reduce water consumption with respect to coloration using natural dyes. In

addition, suitable industrial grade, if possible eco-sustainable (low BOD / COD), coloration

assistants will be investigated to improve desirable properties. It is expected that the research

will result in a coloration system that will be effective in the application of natural dyes on

cotton in an industrially acceptable manner.

In the research project we will study the possibility to improve natural dyeing processes on

natural fibres (both animal and vegetable fibres), in order to discover new possible natural

ways of industrial natural dyeing .

Objectives of Study:

1. To develop a Novel dyeing process for garments dyeing using Natural dyes.

2. To compare the environmental aspects of Natural dye and Synthetic dye in Garments

dyeing

3. To compare the economical aspects of Natural dyeing and Synthetic dyeing on

prospect of Bangladesh.

Methodology of Study:

Objective 1: To develop a Novel dyeing process for garments dyeing using Natural dyes.

The existing dyeing process consist of using synthetic dye with more or less impact .Till now

Bangladeshi garments dyeing factories uses the synthetic dyes and not familiar with natural

dyes. Denim factories can be our major target product for garments dyeing & using of indigo

powder dyes collected from local market can be used for the project. Then the appropriate

mordent, time, temperature, PH is need to be select to established a standard process and final

swatch.

Objective 2: To compare the environmental aspects of Natural dye and Synthetic dye in

Garments dyeing.

There are many factors which can influenced the environmental aspects .The load of

BOD/COD on ETP, water consumption ,steam consumption, energy consumption need to be

compare with existing dyeing process. Also analysis the no impact ability of natural dyes

with reuse of by-product or wastage.

Objective 3: To compare the economical aspects of Natural dyeing and Synthetic dyeing

on prospect of Bangladesh.

In this step need to calculate & compare the dye cost, process cost, utility cost, establishment

cost of existing dyeing process to natural dyeing process. Need to find out the effectiveness

of natural dyeing process on the base of economical aspects.
