Wool

Your answer depends on the thickness of the wool. A thread-weight length will be longer than a bulky-weight yarn.

Yes, in the sense that you can dry a wool garment in a shape that you desire.

With wear, a simple shake or tug on a garment may return it to its original shape.

wool is a insulator

There is a wool fabric made from Himalayan sheep called sherpa wool.

The most common element in wool is animal fleece.

This is probably not a do-able feat, since the felting process encourages all the tiny hooks in the fleece to adhere to each other.

A wool blend coat has been designed not to shrink, based on the blend of the wool.

However, you could wash the wool coat in hot water with maximum agitation, which affects the wool, but not the blend. Your results would be unpredictable.

Both need oxygen and a main heat source like a Bunsen burner witch is a non luminous flame but you can use a wick candle and take a piece of steel wool and fluff it up a bit so oxygen can get in to the spaces to let the steel wool burn faster and more efficient because the oxygen feeds the flame. Then light the fluffed steel wool. You will see a combustion reaction with the steel wool, the oxygen and it's ignition source.

2Fe + 3O2 + heat = then make your observation

The same kind of reaction goes with the rusting of steel wool but it's just oxidization of the iron in the steel and to have a rusting reaction you will need a liquid compound such as water or some time gasoline will rust steel but the test you would do gasoline would not be a safe solution but water would work better because the natural sodium and other minerals would help in the decomposition reaction to the steel

So for the test take steel wool ( just about a half a gram) and jam it in the back of a long but narrow test tube the take a graduated cylinder and put about 50ml just enough for a precipitation reaction ( basically condensation) so the steel wool can have O2 and H2O to rust the steel wool. So put the narrow cylinder test tube face down in the water so the steel wool at the bottom of the test tube us faceing down and not in the water. So right now theirs a tight seal of O2 and H2O vapors allowing a decomposition reaction

Fe + O2 + H2O = observe the results may vary

The similarity is they both use a single decomposition reaction

It is.

A wool bundle is commonly referred to as a "fleece." This term typically describes the raw, unprocessed wool sheared from sheep. After processing, the wool might be packaged in bales, but the initial collection is often called a fleece.

Wool is called fleece when it starts. You shear it off of a lamb or sheep. This is done once or twice a year, depending on the type of sheep and where they live. Shearing is just a short hair cut for the sheep, and if it is done correctly, it doesn't harm the sheep at all.

After the fleece is cut off the sheep, it is washed, dried, combed out (carded), then spun into wool yarn or thread. White wool can be dyed to get many different colors. This can all be done by machines or by hand.

When wool freezes, the fibers can become stiffer and less pliable, which may affect the fabric's overall feel and comfort. However, wool retains its insulating properties even when frozen, as its structure allows it to trap air. If the wool becomes wet before freezing, it may lose some of its insulating capabilities and take longer to dry out. Overall, while freezing affects wool's texture, it does not significantly diminish its warmth.

Winter coats can be made from any textile and serve any purpose. Some winter coats are required to keep humans warm in winter. Other winter coats are for fashion and style only in geographies where winter is not cold.

Rock wool, also known as stone wool, is a popular growing medium used in hydroponics. It is made from melting volcanic rock and spinning it into fibers, creating a lightweight, porous material that provides excellent aeration and moisture retention. Rock wool offers a stable environment for plant roots, supports nutrient absorption, and is pH neutral, making it an ideal choice for hydroponic systems. Additionally, it is sterile, reducing the risk of disease in plants.
