## Core Materials in Sanitary Napkin Production
### 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 plastic film
– Cotton or cotton blends
This layer must be soft, breathable, and quick-drying to prevent skin irritation while allowing fluid to pass through to the absorbent core.
### 2. Absorbent Core
The heart of the sanitary napkin consists of:
– Fluff pulp (wood cellulose)
– Superabsorbent polymers (SAP)
– Sometimes includes cotton or rayon fibers
The absorbent core determines the product’s capacity to retain menstrual flow while maintaining dryness on the surface.
### 3. Back Sheet
This waterproof layer prevents leakage and is usually made from:
– Polyethylene film
– Breathable microporous films
– Biodegradable alternatives in eco-friendly products
### 4. Adhesive Components
Sanitary napkins include:
– Pressure-sensitive adhesive for panty attachment
– Hot melt adhesives for layer bonding
– Release paper for protecting the adhesive before use
## Additional Features and Materials
Modern sanitary napkins often incorporate:
– Side barriers or wings for better protection
– Fragrance additives (though these may cause irritation for some users)
– Antimicrobial treatments
– Colorants for aesthetic appeal
## Quality Considerations in Raw Material Selection
Manufacturers must consider:
– Absorbency rates
– Breathability
– Skin-friendliness
– Environmental impact
– Cost-effectiveness
– Regulatory compliance
## Emerging Trends in Sanitary Napkin Materials
The industry is seeing innovations like:
– Organic cotton options
– Biodegradable and compostable materials
– Chlorine-free bleaching processes
– Plant-based superabsorbent materials
Understanding these raw materials helps consumers choose products that align with their comfort needs, health considerations, and environmental values. As technology advances, we can expect continued improvements in both performance and sustainability of sanitary napkin components.
