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.

Fabric that is gray melange has printed color at intervals. Knit means the fabric in woven or knitted.
A "knit" fabric will stretch, either side to side and/or up to down, but a "woven" fabric will not stretch.
How to get the accurate stretchability of fabric knitted
Knit is a type of fabric but different in the way it is made. Silk and linen are woven tightly. Knit is usually made of a loosely woven fabric that allows it to stretch in different directions. Linen is made from cotton and real silk is made fom the strands of the silk worm and therefore very expensive. Linen and silk are very stable in that they have no stretch. Silk and linen are made from aninal materials and can be worn all year round but are especially comfortable in the summer's heat and humidity. Knits are usually made from plant material usually cotton but some knits are synthetic materials. are made with manmade fibers.
Silk fibres can be woven into a fabric with pinstripes, yes.
Tweed is a material/fabric. It is a wool cloth, rather coarse, and can come in many weaves and colors.
I would say that polar fleece is a woven fabric, made with synthetic fibers.
