Felt is a unique non-woven textile material manufactured by matting, condensing, and pressing fibers together using heat, moisture, and mechanical pressure rather than weaving or knitting threads. It can be crafted from natural wool fibers or synthetic polymers. In industrial and residential applications, heavy asphalt-saturated felt paper is extensively utilized as a protective moisture barrier under roofing shingles and flooring underlayments, while soft craft felt is used for padding and apparel.
