Ends Per Inch
Ends Per Inch (EPI) is a basic measurement used in textile manufacturing that tells you how dense or fine a fabric is. It counts how many vertical threads (called ends) are packed into one inch of fabric width. Think of it like counting fence posts - more posts in the same space means a denser fence. A higher EPI number usually means the fabric is more tightly woven and often higher quality. This measurement is important for quality control and helps determine what the final fabric will be good for - whether it's suitable for light summer clothing or heavy-duty upholstery.
Examples in Resumes

Example Interview Questions
Senior Level Questions
Q: How would you troubleshoot inconsistent EPI measurements across different production batches?
Expected Answer: A senior technician should explain the systematic approach of checking machine settings, yarn tension, loom speed adjustments, and quality control procedures. They should mention the importance of maintaining proper documentation and training operators.
Q: How do you determine the optimal EPI for different fabric types?
Expected Answer: Should discuss how they consider factors like yarn type, fabric end-use, customer specifications, and machine capabilities. Should mention experience with various fabric constructions and quality standards.
Mid Level Questions
Q: What tools and methods do you use to measure EPI?
Expected Answer: Should describe using pick counters, microscopes, or other measurement tools, explain the standard counting procedure, and mention quality control documentation methods.
Q: How does EPI affect fabric quality and properties?
Expected Answer: Should explain how EPI influences fabric strength, appearance, weight, and durability. Should demonstrate understanding of how different EPI values suit different end products.
Junior Level Questions
Q: What is EPI and why is it important in textile manufacturing?
Expected Answer: Should explain that EPI means Ends Per Inch and describes fabric density. Should understand its basic importance in fabric construction and quality.
Q: How do you calculate EPI in a fabric sample?
Expected Answer: Should be able to explain the basic counting process using a pick counter or counting glass, and understand how to record measurements properly.
