About Spandex Yarn

Spandex yarn is a critical raw material for the production of baby diapers, adult diapers, and sanitary napkins. It ensures products are more formfitting, comfortable, and reliable, reducing leakage and irritation while providing a soft, skin-friendly wearing experience.

Compared with traditional elastics, spandex yarn provides 3 times stronger resilient force per Dtex, offering a smoother stress-strain curve and consistent elasticity within the effective elongation area (20%–30%). Its wide elongation range makes it ideal for diaper waistbands, leg cuffs, and side panels.

Key Characteristics of Spandex

• Uniform Tension – Each yarn is made of multiple spun yarns with balanced tension.

• Smooth Stress-Strain Performance – Ensures long-lasting elasticity.

• Stronger Resiliency – 2.0–4.0 times elongation with stable recovery.

• Skin-Friendly – No skin irritation for sensitive baby and adult use.

Benefits for Diaper Manufacturers

1. Lower Cost – High stress and elongation reduce material usage.

2. High Efficiency – Supports long-time continuous production without outage.

3. Clean Surface – No talc powder or dirt, preventing nozzle clogging during hot melt adhesive spraying.

4. Glue-Saving – Excellent compatibility with hot melt adhesive, reducing glue consumption by over 40%.

5. Durability – Excellent creep resistance and long-term elastic stability.
