How does the soft disposable diaper work?

Soft disposable diapers, commonly used for infants and young children, work through a combination of absorbent materials and design features. Here's a simplified explanation of how they typically function:

Outer Layer: The outer layer of a soft disposable diaper is typically made of waterproof or water-resistant material, such as plastic or a breathable cloth-like fabric. It helps prevent leakage and keeps the baby's skin dry.

Inner Layer: The inner layer, in direct contact with the baby's skin, is usually made of a soft, non-irritating material designed to be comfortable and hypoallergenic.

Absorbent Core: The absorbent core is the key component responsible for soaking up and retaining urine and feces. It is typically made of a combination of superabsorbent polymers (SAP) and cellulose fluff pulp. The SAP is a material that can absorb and lock in large amounts of liquid, while the fluff pulp provides additional absorbency.

Elasticized Waistband and Leg Openings: Disposable diapers often have elasticized waistbands and leg openings to provide a snug fit and prevent leaks. The elastic helps create a seal around the waist and legs, reducing the likelihood of urine or feces escaping.

Fastening Mechanism: Disposable diapers usually have adhesive tapes or hook-and-loop fasteners on the sides, allowing the diaper to be securely fastened around the baby's waist. This ensures a proper fit and prevents the diaper from coming undone.
