1. Introduction

Hygiene Spandex yarn is a specialized elastic fiber manufactured to meet the rigorous standards of the personal hygiene industry. Unlike apparel Spandex, this fiber focuses on excellent bonding with hot-melt adhesives and maintaining stable elastic tension on ultra-high-speed diaper production lines.

Hygiene spandex has replaced the traditional rubber material to provide unique styles for hygiene design. It has excellent characteristics more than light weight, good elasticity, and high flexibility. In additional, producing efficiency can be improved and producing cost can be reduced for customers.
Instead of traditional rubber materials, products with different specifications and properties can be customized according to the needs of customer, and are packaged in large silk rolls.

Characterized with large spools patage, excellent unwinding performance, proper mechanical properties and low creep rate, the product is produced by specific process and equipments and custom-made depended on the customer requirement of different specifications and performance.

2. Composition

Hygiene Spandex is composed of long-chain Polyurethane with modified properties:

• Fiber Surface: Treated with a specific silicone oil finish to minimize friction, ensuring smooth delivery through yarn guides on high-speed machines.

• Molecular Structure: Optimized for compatibility with thermal adhesives, ensuring the yarn does not slip or retract once bonded to the product.

3. Key Characteristics

• Excellent Creep Resistance: Prevents the Spandex from slipping or "creeping" within the diaper structure during long-term use or storage.

• Consistent Tension: Maintains uniform elasticity, providing a snug fit without causing red marks on sensitive skin.

• High Safety Standards: Free from harmful impurities, meeting dermatological safety standards for infants and women.

• High Machine Efficiency: Designed to withstand production speeds of 600 to 1000 pieces per minute without breakage.

5. Applications

• Baby Diapers: Used for leg cuffs (leak guards) and elastic waistbands.

• Adult Incontinence Products: Provides a secure fit and leak prevention for elderly care products.

• Feminine Care: Used in menstrual pants and stretchable wing components.

• Medical Masks: Used for soft ear loops that provide comfort during extended wear.

6. Conclusion

Hygiene Spandex yarn is more than just an elastic component; it is a critical factor in the quality of modern hygiene products. The perfect balance of thermal stability, adhesive compatibility, and safety has made this fiber the gold standard for protecting health and ensuring daily comfort.
