# Sanitary Napkin Raw Materials: Essential Components for Hygiene Products
## Introduction to Sanitary Napkin Components
Sanitary napkins are essential feminine hygiene products used by millions of women worldwide. The effectiveness and comfort of these products depend heavily on the quality and combination of their raw materials. Understanding these components helps consumers make informed choices about the products they use during menstruation.
## Core Materials in Sanitary Napkins
### 1. Top Sheet (Cover Stock)
The top layer that comes in direct contact with the skin is typically made from:
– Non-woven fabric (polypropylene or polyethylene)
– Perforated plastic film
– Cotton or bamboo fiber for premium products
This layer needs to be soft, breathable, and quickly absorbent to prevent moisture buildup.
### 2. Absorbent Core
The heart of the sanitary napkin consists of:
– Fluff pulp (wood cellulose)
– Superabsorbent polymers (SAP)
– Combination of both materials
The absorbent core determines the product’s capacity to retain menstrual flow while maintaining dryness.
### 3. Back Sheet
The bottom layer is usually made from:
– Polyethylene film
– Breathable microporous film
– Biodegradable materials in eco-friendly options
This layer prevents leakage while allowing some breathability in premium products.
