Why do sharp polyester prints become blurry, stained or haloed after heat pressing? Learn how disperse dye migration, thermomigration, temperature and print chemistry affect edge definition.

Why does polyester fabric appear darker, lighter or two-toned when viewed from different angles? Learn how filament orientation, yarn lustre, knit geometry, heat pressing and optical reflection create iridescent shine without special dye.

Why can polyester fabric feel firmer after repeated heat setting, sublimation or pressing? Learn how crystallinity, molecular relaxation, DTY crimp, loop flattening and thermal history alter fabric hand and performance.

What temperature is safe for heat pressing polyester? Learn recommended ranges for HTV and sublimation, plus how to prevent scorching, shine, dye migration and fabric distortion.
