# Sanitary Pad Raw Materials: Key Components and Their Functions
## Introduction
Sanitary pads are essential feminine hygiene products used by millions of women worldwide. The effectiveness and comfort of these products depend heavily on the quality and composition of their raw materials. Understanding the key components of sanitary pad raw materials helps consumers make informed choices and manufacturers improve product quality.
## Core Components of Sanitary Pad Raw Materials
### 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 fabric: Provides softness and comfort
– Perforated plastic film: Offers quick-dry properties
– Silk-like materials: Enhances premium feel
Key functions:
– Allows rapid liquid penetration
– Keeps skin dry
– Prevents irritation
### 2. Absorbent Core
This is the most crucial component for fluid management, usually consisting of:
– Fluff pulp: Natural wood fibers for absorption
– Superabsorbent polymers (SAP): Synthetic materials that lock in moisture
– Combination layers: For optimal absorption and distribution
Absorption capabilities:
– Can absorb 10-50 times its weight in liquid
– Prevents leakage
– Maintains dryness
### 3. Back Sheet
The waterproof barrier at the bottom is made from:
– Polyethylene film: Basic waterproofing
– Breathable microporous film: Advanced moisture control
– Cloth-like materials: For premium products
Primary roles:
– Prevents leakage
– Allows air circulation (in breathable versions)
– Provides structural integrity
### 4. Adhesive Components
Various adhesives serve different purposes:
– Pressure-sensitive adhesive: For pad attachment to underwear
– Hot melt adhesive: For bonding layers together
– Release paper: Protects adhesive before use
### 5. Additional Features
Modern pads may include:
