Introduction
The Technology of yarn formation lab aim to know the principle of opening and cleaning process in blow
room and carding and understanding the attenuation process of draw frame, which also helps to the
student learn the gearing diagram of machines and calculate the speed of the various elements and
calculate the production of machines.
Course Objectives
To identify the machine elements of blow room, carding and draw frame
To know the function of elements of blow room, carding and drawing
To know the gearing diagram of machines
Understand the material passage of blow room and carding.
To know function of drafting in draw frame
Course Outcomes
On successful completion of this course, the student will be able to
CO1: Understand the material passage in the spinning machines and draw gearing diagram
CO2: Have knowledge of opening and cleaning
CO3: Understand the attenuation process of Draw frame
CO4: Calculate the mechanical and actual draft in carding
CO5: Calculate the production of blow room, carding and draw frame.

Instructional Strategy
It is advised that teachers take steps to attract student’s attention and boost their learning
confidence.
To help students learn and appreciate numerous concepts and principles in each area, teachers
should provide examples like daily life, realistic situations, and real-world engineering and
technological applications.
The demonstration can make the subject exciting and foster involvement the students a scientific
mindset. Student activities should be observed and planned on all the topics.
Throughout the course, a theory-demonstrate-practice-activity strategy may be used to ensure
that learning is outcome- and employability-based.
All demonstrations/Hand-on practices are under a simulated environment (may be followed by a
real environment as far as possible).
