Specification Checklist
When sourcing elastic for bra straps, specify:
These specs ensure consistent fit, durability, and regulatory safety for premium underwear applications.
Elastic webbing offers 150–300% elongation and 85–95% recovery, ideal for bras that adapt to dynamic body movements throughout the day. Quality nylon-spandex blends maintain shape retention over extended use, making them superior to lower-grade options that degrade quickly under stress. Our testing shows that premium elastic webbing sustains over 90% recovery after 25,000 cycles at 150% elongation, while inferior materials show visible deformation after just 5,000.
Stretch force matters: comfort bras benefit from 8–12N resistance at 200% elongation, while sports bras demand 15–20N to maintain control under high motion. Material stability is equally critical—high-quality elastics hold consistent properties across −10°C to 60°C, ensuring performance during washing or daily wear.
Spandex ratio also affects recovery: 8–12% for everyday bras balances comfort and support, while 15–20% suits high-recovery sports styles.
Design Takeaway: Request test reports showing recovery over 10,000+ cycles at your target elongation. Match spandex content and stretch force to the intended support level for long-lasting comfort and performance.
Elastic webbing is engineered for all-day bra wear, offering softness, consistent tension, and reduced pressure points. It outperforms rigid alternatives by distributing contact force more evenly, reducing peak pressure by up to 70%. Smooth edges, plush textures, and core-spun spandex fibers help minimize skin irritation.
Polyester adds moisture-wicking properties to keep skin dry, while nylon offers strength without harshness. Our dermatological testing confirms that core-spun spandex avoids direct skin contact with elastomers, preventing irritation in sensitive-skin applications. For best results, use 3–5mm thick elastic in daily bras and 6–8mm for sportswear, balancing support with comfort.
Design Takeaway: Choose elastic webbing with certified skin compatibility, soft edge finishing, and appropriate thickness based on application. Always request comfort test results to confirm long-term wear performance.
Elastic webbing is highly adaptable and supports different bra types through variation in width, material strength, and surface treatments. Comfort bras need tensile strength between 50–80N, while sports bras require 200–300N and higher modulus for bounce control. These specs are achieved by adjusting yarn denier, spandex ratio, and weave density.
Width plays a direct role in comfort and performance. A/B cup bras function well with 12–15mm webbing, while C/D cups benefit from 20–25mm. Heavy-duty applications like maternity or athletic bras often require 30–40mm width for broader pressure distribution.
Surface modifications enhance function: plush backing supports sensitive skin; non-roll edges add structure; silicone coatings improve grip for strapless bras.
Design Takeaway: Customize webbing width and tensile profile to the bra’s intended support level. Mix elastic types across zones for comfort/support balance. Confirm structural performance with full-spec samples under simulated use conditions.
Quality elastic webbing maintains 85-90% of its original performance after 200+ wash cycles, provided correct fiber selection and construction methods are used.
In accelerated laundering simulations replicating 2–3 years of typical use, nylon-spandex blends retain stretch within 10–15% of original levels after 200 cycles at 40°C. Lower-grade materials degrade 30–40% after just 50 cycles. Recovery percentage is the key metric: premium elastic retains 85%+ recovery, preventing strap loosening and support loss.
