New white ink formulations for DTF printing have increased stretchability by 50%, reducing cracking on high‑stretch fabrics like spandex and performance wear. Traditional DTF white inks, while opaque, could become brittle after curing, leading to cracks when the garment was stretched. The improved inks use elastomeric resins that flex with the fabric, maintaining integrity through repeated stretching and washing. Independent tests show no cracking after 1,000 stretch cycles, compared to visible cracks after 200 cycles with older formulations.
For print shops using Xinflying DTF printers, the new white inks open up applications in activewear, swimwear, and compression garments—segments previously dominated by sublimation or specialty screen printing. The inks are compatible with standard DTF printheads and require no hardware changes. However, they may need slightly longer curing times or higher temperatures. Several ink suppliers have launched “stretch” product lines, priced about 20% higher than standard white ink. For high‑value athletic apparel, the premium is justified by the durability benefits. As the activewear market continues to grow, stretchable DTF inks will be key to capturing that demand.
