# Sanitary Napkin Raw Materials: Essential Components for Feminine Hygiene Products
## Introduction to Sanitary Napkin Materials
Sanitary napkins are essential feminine hygiene products used by millions of women worldwide. The effectiveness and comfort of these products largely depend on the quality and combination of their raw materials. Understanding the components that go into making sanitary pads helps consumers make informed choices about the products they use during menstruation.
## Core Components of 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 plastic film
– Cotton or other soft natural fibers
This layer needs to be soft, breathable, and quick-drying to maintain comfort while preventing leakage.
### 2. Absorbent Core
The absorbent core is the most crucial part of a sanitary napkin, 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 pad’s absorbency level and thickness.
### 3. Back Sheet
The back sheet prevents leakage and keeps moisture from reaching clothing. Common materials include:
– Polyethylene film
– Breathable microporous films
– Biodegradable materials like PLA (polylactic acid)
