Hot Melt Adhesives in Medical and Hygiene Nonwoven Manufacturing: Diaper Elastic Attachment and Mask Lamination
In baby diapers, adult incontinence products, feminine hygiene, and surgical masks, specialized hygiene hot melt adhesives bond nonwoven spunbond/meltblown fabrics, elastic Lycra strands, and breathable poly backsheets at lines speeds exceeding 1,000 units/min. These adhesives must be hypoallergenic, virtually odorless, pass ISO 10993 skin irritation benchmarks, and demonstrate superior creep resistance on elastic leg cuffs under body heat.
Modern hygiene lines assemble complex multi-layer products at speeds exceeding 15 meters per second. Solvent and water-based adhesives cannot dry fast enough; high-purity hygiene hot melt adhesives provide instant bonding without degrading soft nonwoven textures.
2. The 3 Primary Adhesive Zones: Construction, Core, and Elastic
- Construction Bonding: Laminates topsheet nonwovens to breathable backsheet films with silent, soft drape.
- Elastic Attachment: Bonds pre-stretched elastomeric strands to create leak-proof leg and waist barriers.
- Core Stabilization: Immobilizes fluff pulp and Superabsorbent Polymers (SAP) to prevent wet clumping.
3. Elastic Strand Attachment & Creep Resistance (<5%)
The primary performance benchmark for diaper elastics is the creep test at 38°C body temperature. Jowat and Mayer hygiene adhesives anchor elastic Lycra strands mechanically without strand slippage.

Hot Melt Adhesives in Medical and Hygiene Nonwoven Manufacturing: Diaper Elastic Attachment and Mask Lamination hakkında merak edilenler
What is creep resistance in diaper elastics?
It measures the percentage slippage of tensioned elastic strands under 38°C body temperature; values under 5% ensure zero leakage.
Can hygiene hot melts cause skin irritation?
No. Approved hygiene adhesives pass rigorous ISO 10993 biocompatibility testing, containing zero solvents or allergens.
Which adhesive bonds nose wire strips in surgical masks?
Fast-setting hot melt applied at 140°C–155°C without compromising spunbond filter media.
Why is core adhesive necessary in hygiene pads?
It locks absorbent SAP crystals in place, preventing clumping and leakage when saturated.
