Felt Overview

Felt is a non-woven fabric composed of pressed fibers that typically consists of natural fibers such as wool or cotton, or synthetic fibers such as acrylic. Laser processing of felt can be performed with either a 9.3 or 10.6 micron CO2 laser without a noticeable difference in process quality. Laser processing of felt with a 1.06 micron fiber laser is not recommended as the material does not readily absorb this wavelength. Laser cutting of felt with a CO2 laser, depending on the particular fibers used to make it, will either produce a burnt and discolored cut edge (natural fibers) or a clean cut edge (most synthetic felts). Laser marking of felt with a CO2 laser results in a contrasting, low resolution slightly brown mark. Laser engraving of felt with a CO2 laser will produce a result similar to laser marking of felt but will produce depth into the material.
