An ultrasonic bonding unit joins web layers to anchor elastic threads within passages smaller than the thread cross-section.

A strain-resistant nonwoven core cover retains superabsorbent polymer particles through physical containment and hot melt adhesive bonding.

Composite topsheets combine film masking with porous nonwoven acquisition, resolving the trade-off between stain concealment and liquid wicking speed.

Blending polyolefin with styrenic block copolymer yields elastic films that resist thermal degradation while maintaining processability on standard equipment.

A drive mechanism with a timing belt and regulating rail stabilizes guide member positioning to prevent orthogonal drift during manufacturing.

Bonding a stretchable nonwoven fabric to a nonstretchable layer prevents breakage during manufacturing while maintaining low basis weight.

Sandwiched meltblown layer between ribbon-shaped spunbond layers creates a liquid barrier.

Multi-step stretching of elastic films before lamination reduces bulkiness and manufacturing complexity while maintaining elongation.

An exudate management layer uses a primary fold to direct body exudates into the absorbent core.

Welding protrusions form porous seams while a peeling roller removes thin membranes to resolve the trade-off between structural integrity and breathability.

Ultrasonic welding eliminates adhesive layers to prevent delamination, suppress odors, and maintain air permeability in stretchable laminates.

SBS block copolymer composition achieves high wet peel strength on nonwoven materials without acid-modified resins that cause odor and discoloration.

A manufacturing process stretches a molten web to form a microporous core layer, resolving the trade-off between breathability and liquid barrier properties.
