Why does my shirt have a vinegar smell?

When unpacking a new shirt or hoodie with a direct-to-garment (DTG) print, you might notice a vinegar-like smell or an off-white residue. Don’t worry, that’s not unusual – it’s from a fixation agent applied during the printing process and it’s not permanent.

Fixation agent (sometimes known as pre-treatment) is used for all DTG prints across the industry. It helps the ink bond with the fabric, and without it, the ink would flake off the garment.
