# Sanitary Napkin Raw Materials: Essential Components for Feminine Hygiene Products
## Introduction to Sanitary Napkin Components
Sanitary napkins are essential feminine hygiene products used by millions of women worldwide. These products consist of carefully selected raw materials that work together to provide comfort, absorption, and protection during menstruation. Understanding the composition of sanitary napkins helps consumers make informed choices about the products they use.
## Core Materials in Sanitary Napkins
### 1. Top Sheet (Cover Stock)
The top sheet is the layer that comes in direct contact with the skin. It’s typically made from:
– Non-woven polypropylene
– Perforated film
– Cotton or other natural fibers
This layer must be soft, breathable, and quick-drying to prevent irritation while allowing fluid to pass through to the absorbent core.
### 2. Absorbent Core
The heart of the sanitary napkin consists of:
– Fluff pulp (wood cellulose)
– Superabsorbent polymers (SAP)
– Sometimes includes cotton or other natural fibers
This combination creates a highly absorbent material that locks away menstrual fluid while keeping the surface dry.
### 3. Back Sheet
The back sheet prevents leakage and is usually made from:
– Polyethylene film
