You already know 4-way beats 2-way and how elastane compares to mechanical stretch. Here’s what’s still missing: real specs, a genuine spandex-free option, and how to check a recovery claim before you order.
Short answer: Mibein’s stretch range runs 170–240 g/m², from a spandex-free option (C25171) to a 24% spandex blend (Y35721). The right choice depends on how much recovery you need and whether you want to avoid spandex’s long-term degradation entirely.
Key Takeaways
- Real stretch fabric specs across Mibein’s range run 170–240 g/m², with spandex content from 0% to 24%.
- A genuine spandex-free option (C25171) exists for brands that want stretch without elastane’s known recovery degradation over time.
- For stretch direction, see 4-Way Stretch vs 2-Way Stretch; for fiber mechanism, see Fabric Stretch Ratio: Elastane vs Spandex vs Mechanical Stretch — this page picks up from both.
Beyond Direction and Fiber Type
If you haven’t already, read 4-Way Stretch vs 2-Way Stretch for stretch direction and Fabric Stretch Ratio for how elastane compares to mechanical stretch. Both cover the mechanics well. This page is for the next step — once you know what kind of stretch you need, here’s what’s actually available and how to confirm a supplier’s numbers are real.
Real Stretch Fabric Specs (170–240 g/m²)
| Item | Weight | Composition | Best for |
|---|---|---|---|
| C25171 | 170 g/m² | 100% Polyester, spandex-free | Stretch without elastane |
| TS25116 | 190 g/m² | 100% Polyester | Structured stretch pieces |
| S35817 | 190 g/m² | 100% Polyester | Mid-weight stretch applications |
| Y35721 | 240 g/m² | 76% Poly + 24% Spandex | Maximum stretch and recovery |
Spandex-Free Stretch: A Real Alternative
Elastane-based stretch degrades over time — repeated washing and wear breaks down the elastane fiber, and recovery gets worse with every cycle. C25171 achieves stretch through mechanical construction at the yarn and knit level instead, with no elastane to break down. It’s not a stretch percentage upgrade over a spandex blend; it’s a different trade-off — slightly less maximum stretch, but recovery that doesn’t fade the way elastane does after a season of heavy use.
Stretch Fabric by Garment Type
Recovery needs differ by garment: jogger pants need knee recovery after repeated squatting, a base layer needs full-range recovery through an overhead reach, and a knit blazer needs shoulder mobility without losing structure.
Verifying a Supplier’s Recovery Claims
“Stretchy” or “4-way stretch” with no data behind it doesn’t tell you how it performs after wear. Before ordering, ask for:
- Exact spandex percentage stated as a number, not “stretch-enhanced” or similar vague phrasing
- Recovery-after-wash data if available — how much the stretch percentage changes after repeated laundering
- Whether the stretch is spandex-based or mechanical, since the two behave differently over the garment’s life
Not sure which stretch fits your garment?
Tell Mibein’s team your recovery requirements — including whether spandex-free matters for your program — and we’ll recommend the right fabric.
