How to Choose S, SS, SSS, SMS & SMMS Hygiene Nonwoven Fabric: Complete Buyer’s Guide
How to Choose S, SS, SSS, SMS & SMMS Hygiene Nonwoven Fabric
Hygiene nonwoven fabrics are essential materials used in disposable hygiene products such as baby diapers, sanitary napkins, adult incontinence products, and hygiene pads.
With the rapid growth of global hygiene awareness and population expansion, demand for hygiene nonwoven materials has increased significantly.
According to industry statistics from EDANA and INDA Association of the Nonwoven Fabrics Industry, hygiene applications represent nearly half of the global nonwoven fabric consumption.
In hygiene products, multilayer spunbond and composite nonwoven fabrics such as S, SS, SSS, SMS, and SMMS are widely used due to their excellent balance of softness, strength, breathability, and cost efficiency.
However, choosing the correct structure and material requires understanding the differences between these nonwoven technologies.
This guide explains how to select the most suitable hygiene nonwoven fabric based on structure, GSM, performance, and application requirements.
Global Demand for Hygiene Nonwoven Fabrics
The hygiene industry is the largest consumer of nonwoven fabrics worldwide.
Market research shows that the nonwoven hygiene sector continues to grow due to increasing demand for disposable hygiene products.
| Year | Global Nonwoven Production |
|---|---|
| 2015 | 10.7 million tons |
| 2020 | 13 million tons |
| 2023 | 14.5 million tons |
| 2026 (forecast) | 17 million tons |
Hygiene products account for a significant share of this consumption.
| Application | Market Share |
|---|---|
| Baby diapers | 35–40% |
| Sanitary napkins | 15–18% |
| Adult incontinence | 12–15% |
| Hygiene wipes | 10–12% |
Because these products come into direct contact with skin, hygiene nonwoven fabrics must meet high standards in softness, breathability, and safety.
Understanding S, SS, SSS, SMS and SMMS Nonwoven Fabric Structures
These terms refer to layer structures produced by spunbond and meltblown technology.
Each letter represents a production layer.
-
S = Spunbond layer
-
M = Meltblown layer
Different layer combinations produce fabrics with different performance characteristics.
| Structure | Layer Composition | Key Features |
|---|---|---|
| S | Single spunbond layer | Lightweight and economical |
| SS | Two spunbond layers | Better strength and uniformity |
| SSS | Three spunbond layers | Improved softness and durability |
| SMS | Spunbond + Meltblown + Spunbond | Barrier protection |
| SMMS | Spunbond + Meltblown + Meltblown + Spunbond | Enhanced filtration |
Understanding these structures is the first step in selecting the correct hygiene nonwoven fabric.
Comparison of Hygiene Nonwoven Fabric Types
Different nonwoven structures provide different performance levels.
| Fabric Type | Softness | Strength | Barrier Protection | Cost |
|---|---|---|---|---|
| S | Medium | Medium | Low | Very low |
| SS | Good | High | Low | Low |
| SSS | Very good | High | Low | Medium |
| SMS | Good | High | High | Medium |
| SMMS | Good | High | Very high | Higher |
For hygiene products such as diapers and sanitary napkins, SS and SSS structures are the most commonly used materials because they provide the best balance between softness and cost.
Key Factors When Choosing Hygiene Nonwoven Fabric
Selecting the right hygiene nonwoven fabric involves evaluating several technical parameters.
1 Fabric Weight (GSM)
Fabric weight significantly affects both product performance and manufacturing cost.
Typical GSM ranges for hygiene applications are shown below.
| Application | Recommended GSM |
|---|---|
| Baby diaper topsheet | 10–18 GSM |
| Baby diaper backsheet | 12–25 GSM |
| Sanitary napkins | 12–20 GSM |
| Adult incontinence products | 15–25 GSM |
Lower GSM fabrics reduce production costs but may sacrifice strength or durability.
Therefore, manufacturers must balance cost and performance requirements.
2 Softness and Skin Comfort
Since hygiene products directly contact the skin, softness is a critical property.
SSS nonwoven fabrics are often preferred because the three-layer spunbond structure creates a smoother and softer surface.
| Fabric Type | Softness Rating |
|---|---|
| S | Medium |
| SS | Good |
| SSS | Very good |
Softness can also be improved through special fiber design and finishing processes.
3 Breathability and Air Permeability
Breathability is essential for maintaining comfort and preventing skin irritation.
Spunbond-based structures generally provide excellent air permeability.
| Fabric Type | Breathability |
|---|---|
| S | High |
| SS | High |
| SSS | High |
| SMS | Medium |
| SMMS | Medium |
For hygiene products such as diapers, breathable materials help maintain skin dryness and comfort.
4 Barrier and Liquid Resistance
Some hygiene applications require liquid barrier properties.
SMS and SMMS nonwoven fabrics contain meltblown layers that provide improved filtration and liquid resistance.
| Fabric Type | Liquid Barrier |
|---|---|
| S | Low |
| SS | Low |
| SSS | Low |
| SMS | High |
| SMMS | Very high |
These structures are often used in medical and protective products, but they can also appear in specialized hygiene applications.
5 Production Efficiency and Cost
Cost is an important consideration in large-scale hygiene product manufacturing.
| Fabric Type | Cost Efficiency |
|---|---|
| S | Very high |
| SS | High |
| SSS | Medium |
| SMS | Medium |
| SMMS | Lower |
For this reason, SS nonwoven fabrics dominate the hygiene industry, particularly for baby diapers and sanitary napkins.
Applications of Hygiene Nonwoven Fabrics
Hygiene nonwoven fabrics are widely used in personal care products.
Baby Diapers
Nonwoven fabrics serve as topsheets and backsheet layers.
Sanitary Napkins
Soft spunbond fabrics improve comfort and moisture distribution.
Adult Incontinence Products
High-strength fabrics ensure durability during use.
Hygiene Pads and Liners
Lightweight materials provide breathability and comfort.
These applications require materials that combine softness, strength, and safety.
How to Choose a Reliable Hygiene Nonwoven Fabric Supplier
Selecting a reliable supplier ensures consistent product quality and stable supply.
Important evaluation criteria include:
| Supplier Factor | Importance |
|---|---|
| Production capacity | Ensures reliable supply |
| Quality control | Maintains consistent fabric performance |
| Certification | Confirms compliance with hygiene standards |
| Customization ability | Supports product development |
Manufacturers should also request:
-
technical data sheets
-
product test reports
-
sample materials
before finalizing supply agreements.
