What is Felt?

Felt is a very versatile and resilient industrial fabric that is manufactured using different processes.

Needle Punch Process:

A fiber such as polyester is interlocked using a machine with thousands of needles moving in an up and down motion.  Heat is then applied using a calendar roll to make a smoother surface and remove fuzziness from the felt.  Calendaring can also be used to produce a firmer sheet.  A binder can be added to felt that needs to be thermo-formable.

Woven:

Wool or wool blended with other yarn are woven into cloth and then felted using steam and pressure to interlock the fibers.

Pressed:

Wool fibers or wool blended with other fibers are pressed together with steam and pressure that allows the fibers to naturally interlock.
