A digitising process converts artwork into stitch paths, and a machine works those paths through the cloth with a stabiliser backing it. The design is built entirely from thread: no adhesive, no film, no dye. That is why it does not crack, peel, melt or fade in any of the ways the other methods do.
Embroidery ages well, so problems are usually mechanical rather than gradual:
A snagged thread should be pushed back through to the reverse with a needle, never cut on the face and never pulled.
Embroidery tolerates washing better than any glued decoration, so the constraint is usually whatever else is on the garment. Turn it inside out to protect the raised surface from abrasion, wash cold, dry flat. Press from the reverse over a towel so the stitching is not flattened. See Garment Care.
