Does laser cutting fabric cause singed edges or yellowing?

Laser cutting is, by its nature, a thermal process: synthetic fibers (polyester, nylon) melt when heated, causing the cut edges to seal automatically—preventing fraying and pilling. This is the greatest advantage of laser cutting synthetic fibers; natural fibers such as cotton and linen do not melt, so the cut edges will carbonize and turn yellow.

Therefore, whether to use a laser depends on your fabric composition and post-processing requirements. The most reliable approach is to send us a fabric sample for a test cut; we’ll send you photos of the cut edge so you can decide whether to use a laser, a vibrating knife, or die-cutting.
