Napping (or raising) is a finishing process that lifts fibres from the fabric surface to create a soft, fuzzy texture.
The Process
Napping uses:
- Rotating cylinders covered with fine wire teeth
- Teeth catch and pull fibres upward
- Creates raised, soft surface
- Can be done on one or both sides
Effect
Napped fabric has:
- Soft, fuzzy hand feel
- Improved warmth (trapped air)
- Slightly reduced strength
- Changed appearance
In Towels
Napping is occasionally used on:
- Budget towels (creates softness cheaply)
- Certain finishes
- Blanket-style throws
Heavy napping can weaken towels and cause shedding.
Flannel
Flannel fabric is the classic napped textile - cotton woven fabric with raised, brushed surface.
