Rationale:
Dyeing is the important process to provide aesthetic feel to the textile fabric which are made from natural, regenerated and synthetic fibres and their blends. So studying the different methods and mechanism of dyeing techniques and various types of dyes available in the market for the above referred fibres are must for the students.
Objectives:
Unit 1 : Soluble Dyes for Cotton
- To know the basic terminology used in the dyeing industry.
- In depth study of reactive dye is being given to do cotton dyeing.
Unit 2 : Insoluble and Ingrain dyes for Cotton
- To study about the basic mechanism of dyeing of cotton using insoluble dyes (Vat and sulphur dye) and Ingrain dyes.
- To compare the application mechanism of Insoluble dyes.
Unit 3 : Disperse Dyes
- To impart the knowledge of dyeing of polyester using disperse dye
- Various types of dyeing of Polyester is added to get the best out of the available resources in the industry.
Unit 4 : Acid and Basic Dyes and Blend Dyeing
- Dyeing mechanism and the role of auxiliaries used in dyeing of Acid and Basic dyes is being studied so as to dye acrylic and silk..
- In order to dye the blended fabric, mechanism of commonly used dyes and combination is being studied.
Unit 5 : Quality Assurance in Preparation and Colouration
- This unit will give an idea about the efficiency of the preparatory processes and the extent to which the fibres get damaged.
- This chapter is giving the knowledge of the ability of the dye to withstand in different environment (like washing, rubbing etc.)
- By knowing this one can control the dyeing conditions to get optimum result in the given class of dyes.
