# Sanitary Napkin Raw Materials: Essential Components for Hygiene Products
## Introduction to Sanitary Napkin Components
Sanitary napkins are essential feminine hygiene products designed to provide comfort and protection during menstruation. The effectiveness of these products largely depends on the quality and composition of their raw materials. Understanding these components 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 (most common)
– Perforated plastic film
– Cotton or other natural fibers (in premium products)
This layer needs to be soft, breathable, and quick-drying to maintain comfort.
### 2. Absorbent Core
The absorbent core is the most crucial component, responsible for fluid retention. It usually consists of:
– Fluff pulp (wood cellulose)
– Superabsorbent polymers (SAP)
– Combination of both materials
The ratio of these materials determines the absorbency level of the pad.
### 3. Back Sheet
The back sheet prevents leakage and is typically made from:
– Polyethylene film
– Breathable microporous film
– Biodegradable materials in eco-friendly options
This layer must be waterproof yet comfortable against clothing.
## Additional Components
