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.
