Wet processing is one of the major streams in Textile Engineering refers to textile chemical processing engineering and applied sciences.Wet process is done on fiber, yarn, fabric and garments. The processes of this stream is involved or carried out in aqueous stage and thus it is called wet process which usually covers pretreatment, dyeing, printing and finishing.

All of these stages are required aqueous medium which is created by water. A massive amount of water is required in these processes per day. It is estimated that, on an average, almost 100 liter of water is used to process only 1 kg of textile goods. Water can be of various quality and attributes. Not all water can be used in the textile process, it must have some certain properties, quality, color & attributes for being used in textile processes. That is why water is a prime concerned in wet processing engineering.

Course Objectives:

After the completion of this course, students will be able to-

• Learn in-details about dyeing process of textiles with reactive, sulphur, azoic and disperse dyes by using discontinuous and continuous methods.
• Know about printing process of woven and knit fabrics with reactive, sulphur, azoic and disperse dyes by using different methods, including block, screen and roller printing methods.
• Attain knowledge about important chemical and mechanical finishes, such as textile mercerization, resin finishing, water repellent finishing and shearing process.
