Synthetic fibers or a blend of wool and synthetic fibers are interlocked using machines with thousands of needles moving in an up/down motion to mechanically interlock the fibers.
Wool blends are less expensive than pressed or woven blends but tend to exhibit a bevel at the edge of cut parts.
Cut parts do not fray and loose fibers are minimal.
Maximum thickness 1-1/2".
Typical uses include:
Inexpensive substitute for Pressed Felts
Felt bottoms for lamps
