Zeal to learn the subject


This course provides basic idea of different intermediates and their manufacturing processes, used in the synthesis of Dyes. It also gives the knowledge of classification of colourants, their properties and their application methods. Apart from textile, the other areas of applications of these colorants are also explored. The various ecotoxilogical effects of synthetic dyes and the chemicals used therein are also covered.

Course Outcome

After learning the course, the students should be able to:

  1. Understand the basics of various raw materials and intermediates used in the manufacturing of Dyes.
  2. Understand the technical aspects of various unit operations employed in the manufacturing of different intermediates.
  3. Understand the basis of classification of different colouring matter.
  4. Understand the technical aspects of different manufacturing methods employed in the synthesis of dyes.
  5. Understand different application methods of dyes on textiles.
  6. Get the knowledge of areas of non textile applications of Dyes such as leather, paper, food etc.
  7. Understands the concept and classification of colorless dye e.g. Optical brightening agents.
  8. Understand Color i.e. definition, colorimetric terms and different colour theories.
  9. Get the knowledge of current scenario of Dyestuff industries.
  10. Understand ecotoxilogical effects of dyes and the chemical used therein on environment.

Active Learning

Preparation of power-point slides, which include videos, animations, pictures, graphics for better understanding theory and practical work – The faculty will allocate chapters/ parts of chapters to groups of students so that the entire syllabus to be covered. The power-point slides should be put up on the web-site of the College/ Institute, along with the names of the students of the group, the name of the faculty, Department and College on the first slide. The best three works should submit to GTU.
