# Sanitary Napkin Raw Materials: Essential Components for Feminine Hygiene Products
Sanitary napkins are an indispensable part of feminine hygiene products, providing comfort and protection during menstruation. The quality and effectiveness of these products largely depend on the raw materials used in their production. Understanding the components that go into making sanitary napkins can help consumers make informed choices about the products they use.
## Core Components of Sanitary Napkin Raw Materials
### 1. Top Sheet (Cover Stock)
The top sheet is the layer that comes in direct contact with the skin. It needs to be soft, non-irritating, and highly absorbent. Common materials used include:
– Polypropylene non-woven fabric
– Perforated plastic film
– Cotton-like materials for premium products
### 2. Absorbent Core
This is the most crucial part of the sanitary napkin, responsible for absorbing menstrual flow. The core typically consists of:
– Fluff pulp (wood pulp)
– Superabsorbent polymer (SAP)
– Combination of both materials
### 3. Back Sheet
The back sheet prevents leakage and keeps moisture from reaching clothing. Materials used include:
– Polyethylene film
– Breathable microporous film
– Cloth-like materials for premium products
### 4. Adhesive Components
These ensure the pad stays in place during use:
– Pressure-sensitive adhesive for attachment to underwear
– Release paper to protect the adhesive before use
## Additional Features in Modern Sanitary Napkins
### 1. Side Barriers
Many modern pads include side barriers or wings to prevent leakage. These are typically made from:
– Polyethylene or polypropylene materials
– Elastic components for better fit
### 2. Fragrance Components
Some manufacturers add:
– Microencapsulated fragrance beads
– Natural essential oils for odor control
### 3. Indicator Strips
Premium products may include:
– Color-changing strips to indicate saturation
– Printed patterns that disappear when wet
