Rationale:
Due to the high volume of export and the local need of the textile goods, it is inevitably necessary to produce in a bulk and quicker rate. It is possible by the modern machines with latest technology. This subject covers basic textile chemistry, singeing, desizing, and mercerising, scouring, bleaching and preparatory process for non – cellulosic fibres. Hence, it fulfills the above need.
The various sequences of processes like singeing, desizing, scouring, mercerizing, bleaching have to be included and knowledge on drying machines provides the basic inputs required in the subject of preparatory processes for textile processing.
Objectives:
- To acquire knowledge in basics of textile chemistry.
- To understand the chemistry of various auxiliaries used in textile wet processing.
- To understand the basic structure of fibre forming polymers and its effect on processing.
- To learn the basic principle of singeing.
- To study the types of desizing and their principles.
- To study the machines used for singeing and desizing
- To have an understanding of effects of mercerization.
- To have an idea about liquid ammonia treatment.
- To thoroughly impart knowledge in scouring of cotton.
- To acquire knowledge in understanding different types of bleaching agents used.
- To study about bleaching of cotton material using hydrogen peroxide
- To have an idea about single stage desizing, scouring, bleaching.
- To impart ideas about the preparatory processes of non-cellulosic fibres.
- To give emphasis in preparatory sequence of polyester.
- To understand the principles of hydro extraction & drying.
