# Sanitary Napkin Raw Materials: Essential Components for Feminine 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 sheet is the layer that comes in direct contact with the skin. It’s typically made from:
– Non-woven polypropylene
– Perforated film
– Cotton-like materials
This layer needs to be soft, breathable, and quick-drying to ensure comfort while preventing irritation.
### 2. Absorbent Core
The absorbent core is the heart of the 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 absorbency level of the product.
### 3. Back Sheet
The back sheet prevents leakage and keeps moisture from reaching clothing. Common materials include:
– Polyethylene film
– Breathable microporous films
– Biodegradable alternatives like PLA (polylactic acid)
### 4. Adhesive Components
Several adhesive elements are used in sanitary napkins:
– Pressure-sensitive adhesive for panty attachment
– Hot melt adhesives for layer bonding
– Release paper for protecting the adhesive before use
## Additional Features and Materials
