Most of the times with fabrics you need very tiny hairs sticking out randomly.
Also most of the times this is solved with a falloff, which doesn't really give a realistic effect.
Using hair and fur seems overkill.
What if...
In the material, you have a checkbox "fuzziness", which creates pixels in a curly line with an offset to the fabric, same color as the underlaying color, that reacts to light by increasing gamma only where the light hits, as translucency.
This would NOT be an effect for close up views. It's just to add softness to a fabric.
