Pressed Wool Felt
Pressed Wool Felt
Pressed wool felt is made via an intricate process often referred to as "wet processing". Fibers are worked together by pressure, moisture, and vibration, then carded and cross-lapped to make multiple layers of material. The ultimate thickness and density of the material determines the amount of layers that are then steamed, wetted, pressed and hardened.
The majority of fiber used in pressed felt is wool. Wool fibers have small barbs on them, which aids in the natural locking or felting process. The manufacturing of pressed wool felt is primarily mandated by SAE standards (see SAE Felt Specification Chart below). These standards determine the wool content, density, and other physical and mechanical properties of the felt. Pressed wool felt is identified by the SAE standards F-1 through F-26.

The lower the SAE numbers will be more machinable, have better vibration absorption, and better abrasion resistance. Wool felt has excellent wicking properties. It can absorb several times its weight in oil, and when used as a lubrication wick, it will supply small amounts of oil at a uniform rate. Pressed wool felt has excellent solvent resistance and stability in oil. SAE wool felt is unaffected by sunlight and maintains its original form after long periods of stress.
