Yarn Engineering Lab
Operate spinning machinery, produce sample yarns, conduct quality tests, and master calculations for industrial-scale yarn production.
By the end of this lab course, students will be able to:
- Identify & Operate Spinning Machinery
- Recognize the parts and working principles of blow room, carding, drawing, roving, and ring spinning machines.
- Demonstrate safe operation, material handling, and machine settings.
- Understand & Perform Yarn Formation Processes
- Carry out basic operations of opening, cleaning, carding, drafting, roving, twisting, and winding.
- Relate machine adjustments (draft, twist, speed) to yarn properties.
- Conduct Yarn Calculations
- Calculate draft, twist, yarn count, production rate, and efficiency.
- Estimate waste percentage and material balance during spinning processes.
- Produce and Inspect Yarns
- Produce sample yarns from different fibers using lab-scale spinning systems.
- Identify common yarn defects (thick places, thin places, neps, hairiness).
- Test and Evaluate Yarn Properties
- Measure yarn count, strength, elongation, evenness, and twist.
- Analyze the relationship between fiber properties, spinning parameters, and yarn quality.
- Develop Practical & Industrial Skills
- Troubleshoot operational issues during yarn production.
- Relate lab-scale learning to industrial spinning practices.
