1. Polyester Interlock — The Sublimation Workhorse
Interlock is a tightly knitted polyester fabric with a smooth face and a soft, dense hand feel. It is the standard base for sublimated game jerseys — including custom basketball uniforms — because full-color artwork dyes directly into suitable polyester fabric, giving all-over designs that cannot crack or peel. Interlock's fine knit also gives a clean, pro look for soccer kits and practice jerseys.
