Course Outcomes:
On completion of the course, the student will be able to:
- Discuss the concepts of Ginning and Mixing, Study the working of Blow room machines.
- Describe the concept and working of carding and drawing machine.
- Discuss the method of lap preparation for combing machine, the working mechanism of comber.
