Spandex 560D for baby diaper

In the manufacturing of modern baby diapers and adult incontinence products, the performance of elastic materials directly determines the product's fit and leak-proof effect. Our high-performance spandex elastic yarn is designed specifically for high-specification automated production lines for hygiene products and is the core raw material for creating the 3D leak-proof side panels and outer thigh guards of diapers.
This product uses a precision composite spinning process, perfectly combining the strong resilience of natural rubber, the weather resistance of synthetic rubber, and the high elongation of spandex fibers. Compared to traditional coarse adhesive strips, it has an extremely fine fineness and a gentle stress-strain curve. This means that it can provide highly uniform and gentle tightening force under tension, allowing the diaper to actively stretch and contract with the baby's body when crawling, rolling, and kicking. This ensures a close fit to the thighs and waist, sealing gaps to prevent side leakage, while completely avoiding marks, redness, or allergic irritation to delicate skin.
Furthermore, this product has excellent surface rheological properties, enabling it to form a perfect bond with mainstream structural/elastic hot melt adhesives (such as silicone resin adhesives with high creep resistance). Its ultra-wide extension area allows users to significantly reduce material consumption while maintaining the same elasticity. The high-toughness filament design supports long-term, high-speed, uninterrupted unwinding without unwinding or filament breakage, helping your automated factory achieve high output, low energy consumption, and high profit margins.
