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 various raw materials. Understanding these components helps consumers make informed choices and manufacturers maintain high production standards.
## Core Materials in Sanitary Napkins
### 1. Absorbent Core
The absorbent core is the most critical component of a sanitary napkin. It typically consists of:
– Fluff pulp (wood cellulose)
– Superabsorbent polymers (SAP)
– Sometimes includes cotton or rayon fibers
This combination creates a highly absorbent layer that quickly pulls moisture away from the body.
### 2. Top Sheet (Cover Stock)
The top sheet is the layer that comes in direct contact with the skin. Common materials include:
– Nonwoven polypropylene
– Perforated plastic films
– Cotton or cotton-blend materials
Modern top sheets are designed to be soft, breathable, and quick-drying to maintain comfort.
### 3. Back Sheet
The back sheet prevents leakage and keeps moisture locked inside. Materials used include:
– Polyethylene films
– Breathable microporous films
– Biodegradable materials in eco-friendly options
## Additional Components
### 1. Adhesive Strips
