# Sanitary Napkin Raw Materials: Essential Components for Hygiene Products
## Introduction to Sanitary Napkin Components
Sanitary napkins are essential feminine hygiene products designed to provide comfort and protection during menstruation. The effectiveness of these products largely depends on the quality of their raw materials. Understanding the components that go into manufacturing sanitary napkins helps consumers make informed choices about the products they use.
## Core Materials in Sanitary Napkin Production
### 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, preventing leaks and maintaining dryness.
### 2. Top Sheet (Cover Stock)
The top sheet is the layer that comes in direct contact with the skin. Common materials include:
– Non-woven polypropylene
– Perforated film
– Cotton-like materials
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 provides structural integrity. Materials used include:
– Polyethylene film
– Breathable microporous films
– Biodegradable materials like PLA (polylactic acid)
Modern back sheets often feature adhesive strips to secure the napkin in place.
## Additional Components
### 4. Adhesives
Sanitary napkins use various adhesives for:
– Securing the pad to underwear (pressure-sensitive adhesives)
– Bonding different layers together (hot melt adhesives)
### 5. Release Paper
This protective layer covers the adhesive before use and is typically made from:
– Siliconized paper
– Plastic films
### 6. Fragrance and Additives
Some sanitary napkins may include:
– Odor-control agents
– Aloe vera or other soothing additives
– Antimicrobial treatments
## Emerging Trends in Raw Materials
The sanitary napkin industry is evolving with new material innovations:
