Flannel Fabric
Nature — What Is Flannel Fabric?
Flannel fabric is a soft woven textile known for its brushed surface (created by raising fine fibers from the yarn surface).
It is valued for its warmth and comfort (the brushing process increases insulation and softness).
Scientific Structure (Explained Clearly)
Flannel is typically woven in plain or twill weave (then mechanically brushed to lift surface fibers).
Structural Characteristics
- Brushed surface finish (fibers are lifted to create softness)
- Wool or cotton yarn base (natural fibers enhance insulation)
- Medium yarn density (balances warmth and breathability)
Fabric Impact
- Soft hand feel
- Improved heat retention
- Comfortable against skin
Performance — How Flannel Fabric Behaves
1. Warmth
Traps body heat effectively (brushed fibers hold insulating air).
2. Softness
Feels smooth and cozy (raised fiber surface reduces roughness).
3. Breathability
Allows moderate airflow (natural fiber construction enhances comfort).
4. Comfort Flexibility
Adapts to everyday wear (flexible weave supports movement).
