# 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. Absorbent Core
The absorbent core is the most crucial component of a sanitary napkin. It typically consists of:
– Wood pulp (cellulose fibers)
– Superabsorbent polymers (SAP)
– Fluff pulp
These materials work together to quickly absorb and retain menstrual fluid, keeping the surface dry and comfortable.
### 2. Top Sheet (Cover Stock)
The top sheet is the layer that comes in direct contact with the skin. Common materials include:
– Non-woven fabric
– Perforated film
– Cotton cover
This layer needs to be soft, breathable, and allow quick liquid penetration while keeping the surface dry.
### 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
Modern sanitary napkins often use breathable back sheets to enhance comfort and reduce skin irritation.
## Additional Components
### 1. Adhesive Strips
Most sanitary napkins feature:
– Pressure-sensitive adhesive for attachment to underwear
– Wing adhesives for secure placement
### 2. Release Paper
This protective layer covers the adhesive before use and is typically made from:
– Silicon-coated paper
– Plastic film
### 3. Fragrance Components (Optional)
Some products include:
– Natural essential oils
– Synthetic fragrances
– Deodorizing agents
## Specialized Materials in Premium Products
High-end sanitary napkins may incorporate:
– Organic cotton topsheets
– Bamboo charcoal fibers for odor control
– Aloe vera or vitamin E coatings for skin care
