## Core Diaper Components
### 1. Outer Layer (Backsheet)
The waterproof outer layer typically consists of:
– Polyethylene film
– Breathable microporous films
– Nonwoven fabric laminates
### 2. Inner Layer (Topsheet)
This soft layer against baby’s skin usually contains:
– Polypropylene nonwoven fabric
– Hydrophilic treated materials
– Perforated or embossed designs for better dryness
### 3. Absorbent Core
The heart of the diaper’s functionality includes:
– Superabsorbent polymers (SAP)
– Fluff pulp (cellulose fibers)
– Distribution layers for even liquid spread
## Additional Diaper Materials
### 4. Elastic Components
– Polyurethane or synthetic rubber strands
– Spandex fibers for leg cuffs
– Elastic nonwovens for waistbands
### 5. Fastening Systems
– Hook-and-loop closures (often polypropylene)
– Adhesive tapes
– Stretchable side panels
### 6. Wetness Indicators
Some premium diapers feature:
– Color-changing inks
– Printed designs that fade when wet
## Safety Considerations
All materials must meet strict safety standards regarding:
– Skin irritation potential
– Chemical migration limits
– Breathability requirements
– Hypoallergenic properties
Manufacturers continually innovate with new materials to improve performance while maintaining safety and comfort for babies. Understanding these components helps parents make informed choices about diaper products.
