What Is Elastic Tension Control?
Direct Answer
Elastic tension control is the precision regulation of stretch ratio when elastics (typically spandex) are applied, preventing fit that is too tight or too loose.
Key Takeaways
- Elastic tension control is the precision regulation of stretch ratio when elastics (typically spandex) are applied, preventing fit that is too tight or too loose.
- How it works: Servo-driven rollers feed elastic strands at a controlled stretch ratio before they are bonded to the web.
- Leg cuff elastic application at controlled stretch
- More stretch is always better — excessive tension causes red marks and discomfort; the target ratio balances fit and comfort
How Elastic Tension Control Works
Servo-driven rollers feed elastic strands at a controlled stretch ratio before they are bonded to the web. Correct tension gives consistent leg and waist gathers; wrong tension causes red marks, baggy fit or broken elastics.
Examples and Applications
- Leg cuff elastic application at controlled stretch
- Waistband elastics in pull-ups

Why does elastic tension matter in diaper production?
Inconsistent tension makes diapers too tight (red marks) or too loose (leaks). Precise control keeps fit consistent across millions of units.
