I would say that polar fleece is a woven fabric, made with synthetic fibers.
Polar fleece is made from synthetic fibers that are knit or woven in a way that prevents fraying. The fibers are bound tightly together, creating a smooth edge that resists unraveling.
Yes, they can be woven, felted, knit, crochet. The fleece can be cleaned, carded, spun, or just used right off the alpaca.
Polyester fleece (polar fleece) is knitted. It is made in a similar way to sweatshirt material. Sweatshirt material has what is called a 'floating yarn' on one side (fleecy has these yarns on both sides), which is a yarn that only loops through the fabric infrequently so it creates loops. This side can be un-brushed (with one side like terry-towel) or it can be brushed (fuzzy on one side). This brushing technique is what makes polyester fleece so fuzzy.

woven, I'm pretty sure.
How can synthetic fleece be made from pop bottles?Fleece is made of polyester, a petroleum-based synthetic that can be spun into fibers or molded into plastic.The bottles are separated by color, sterilized and then crushed, chopped and melted.The melted plastic is extruded through a shower-head type device, producing fibrous polyester strands. Those strands are stretched to thin out and strengthen them.The strands are woven into fleece or other materials, such as T- shirts and sweats
Synthetic fleece is made by melting plastic pellets, typically polyester or polyethylene terephthalate (PET), into a liquid form and then extruding it through fine holes to create thin strands. These strands are then twisted together to form fibers, which are woven or knit into fabric to create the soft, fuzzy texture of fleece.
knit?
A non-woven material would be a knit.
Woven but look it up on wiki. Denim is a diagonal twill weave.
