Direct Answer

A composite core machine is production equipment that builds wood-pulp-free absorbent cores by combining multiple nonwoven layers with SAP in precise patterns.

Key Takeaways

  • A composite core machine is production equipment that builds wood-pulp-free absorbent cores by combining multiple nonwoven layers with SAP in precise patterns.
  • How it works: Instead of forming fluff pulp into a pad, a composite core machine lays nonwoven sheets and deposits SAP in controlled zones (for example, more polymer toward the center), then seals the layers.
  • Composite diaper cores used in premium thin diapers
  • Composite cores are weaker — they are engineered for flexibility and can be very strong when layer bonds are correct

How Composite Core Machine Works

Instead of forming fluff pulp into a pad, a composite core machine lays nonwoven sheets and deposits SAP in controlled zones (for example, more polymer toward the center), then seals the layers. The result is a thinner, more flexible core with targeted absorption.

Examples and Applications

  • Composite diaper cores used in premium thin diapers
  • Zoned SAP placement for targeted absorbency
