    • Answer: Comb speed adjustment depends on fiber type and desired quality. It's a balance between efficiency and fiber damage.

16. What are the different types of fiber that can be combed?

    • Answer: Combing is used for various fibers like cotton, wool, silk, and blends, though the process parameters vary.

17. How does the type of fiber influence the combing process?

    • Answer: Fiber length, strength, and fineness dictate the combing parameters (speed, pressure, etc.) to prevent damage.

18. What are the quality parameters you monitor during combing?

    • Answer: Key parameters include noil percentage, fiber parallelism, nep count, and yarn evenness.

19. How do you deal with machine breakdowns during production?

    • Answer: Follow safety protocols, assess the problem, attempt basic troubleshooting, and if necessary, call for maintenance support.

20. What is the role of the top comb and bottom comb?

    • Answer: The top and bottom combs work together to align and disentangle the fibers, removing impurities and short fibers.

21. What are the common causes of fiber entanglement?

    • Answer: Entanglement can stem from poor fiber preparation, incorrect machine settings, or machine wear and tear.

22. How do you prevent fiber damage during the combing process?

    • Answer: Careful adjustment of machine parameters, regular maintenance, and use of appropriate lubricants can prevent damage.

23. What is the importance of regular cleaning of the comber?

    • Answer: Regular cleaning removes accumulated dust, lint, and other debris, preventing blockages and maintaining efficiency.

24. Describe the process of setting up a comber for a new fiber type.

    • Answer: This involves adjusting various parameters based on fiber properties, including feed rate, nipper settings, comb speed, and detaching mechanism settings.

25. How do you monitor the quality of the combed fibers?

    • Answer: Quality is monitored through visual inspection, fiber length measurement, and testing for strength and evenness.

26. What are the key performance indicators (KPIs) for a comber setter?

    • Answer: KPIs include production rate, yarn quality, machine uptime, and waste percentage.

27. How do you manage waste generated during the combing process?

    • Answer: Waste is collected, potentially recycled or disposed of according to environmental regulations.

28. What is the importance of following safety regulations while working with a comber?

    • Answer: Following regulations ensures the safety of the operator and prevents accidents.

29. How do you identify and rectify a problem with the fiber delivery system?
