wicking fabrics are spun with a lumen: a tube running through the middle. The water literally has a drain tube. Cotton has one, for instance.
Mercerizing cotton narrows the lumen. Also, water comes in and forms chemical bonds with the water- that's why you steam whenyou iron, instead of just ironing. Wool also absorbs water- that "wet dog" smell is a sulphur bond breaking open.
Fleece: spun by people, with different formulae, and different physical characteristics- some have a lumen, some are finer spun than hair, some are crimped, some are thick, some have smooth outer cores, some don't. In general, they are oleophilic, rather than hydrophilic- they abosrb and keep oil, not water. Which means eventually they all get that nasty seventies polyester bowling shirt funk. Also, that's why they make good diapers- (diapers aren't oily), and wretched tee- shirts ( pizza, spaghetti, egg rolls, armpit sweat). And also why nobody in their right mind buys tailored goods made from poly/fleece.acrylic/vinyl fabrics- they won't last ten to fifty years like a good wool suit would.
Are you assuming baked 'nads, or migrating fibers? I can't vouch for the overheated parts, but for fibers- don't buy cheap fabric, of any sort.
