Engineering Excellence How Custom Swimwear Fabric Printing Works: Sublimation vs. Direct Wet Print
In modern swimwear procurement, selecting the right printing mechanism is directly dictated by your base textile yarn chemistry. At Bikinova Swimwear Co., Ltd., we run advanced digital dye-sublimation and specialized acid wet printing directly calibrated for four-way stretch elastane structures.
When engineering for Recycled Polyester (rPET), digital dye-sublimation utilizes eco-certified disperse inks printed onto high-release transfer paper. Under exact thermodynamic calender parameters (195–205°C with controlled linear dwell pressure), solid dye crystals sublimate instantly into gas without liquid phase, bonding intimately inside the synthetic polymer core. This guarantees zero cracking, retains 100% of the textile breathability, and produces zero industrial effluent.
For high-end luxury resortwear running ECONYL® regenerated Polyamide (Nylon 6), we employ specialized digital acid printing. Nylon fibres possess amine end-groups that demand specialized ionic bonding. We apply a targeted sodium alginate pre-treatment bath, execute drop-on-demand acid inkjet patterning, and finish through pressurized loop steam fixation followed by closed-circuit tensionless washes. This process guarantees deep color saturation into the micro-cavities of the yarn, completely banishing the dread of white grin-through when stretched across the body.
