# Raw Material for Diaper Production
## Introduction to Diaper Raw Materials
The production of diapers requires a variety of specialized raw materials that work together to provide comfort, absorbency, and leak protection. Understanding these materials is essential for manufacturers and those interested in the diaper industry.
## Key Components in Diaper Manufacturing
### 1. Absorbent Core Materials
The most critical component of any diaper is its absorbent core, which typically consists of:
– Superabsorbent polymers (SAP)
– Fluff pulp (wood cellulose fibers)
– Combination of SAP and fluff pulp
### 2. Top Sheet (Inner Layer)
The layer that comes in direct contact with the baby’s skin is made from:
– Non-woven polypropylene
– Polyester fibers
– Sometimes with added lotions for skin protection
### 3. Back Sheet (Outer Layer)
This waterproof layer prevents leaks and is typically composed of:
– Polyethylene film
– Breathable microporous films
– Sometimes with cloth-like covers for premium products
### 4. Elastic Components
Various elastic materials provide comfort and fit:
– Polyurethane or polyester elastomers for leg cuffs
– Elastic strands for waistbands
– Stretchable side panels
### 5. Adhesives and Fastening Systems
These include:
– Pressure-sensitive adhesives
– Hook-and-loop fasteners (like Velcro)
– Tape systems
## Environmental Considerations in Material Selection
