Seamless tech: why our shower curtains have no hem
Look at the bottom of most fabric shower curtains. The edge is folded over two or three times and stitched down. It looks tidy on day one, but that fold is exactly where water collects after every shower, and a hem that stays damp is where mold likes to start.
OneSevenNine° seamless shower curtains don't have that hem. Here is what we do instead, and why.
The trouble with a stitched hem
A sewn hem stacks several layers of fabric and holds them together with thread. Water running down the curtain soaks into the fold and the stitching and stays there long after the rest of the curtain has dried. Soap and grime settle into the same spot, which is why the bottom edge is usually the first part of a curtain to look tired.
Left: a folded, stitched hem holds water between its layers. Right: one flat, sealed edge lets water run straight off.
Cut and sealed in one step
Instead of folding and sewing, we cut the edges of our seamless curtains ultrasonically. The cutting tool vibrates at ultrasonic speed, and the energy fuses the fibres right at the cut line. The edge is cut and sealed at the same moment, so there is no stitched hem and no loose threads.
The vibrating tool fuses the fibres as it cuts, leaving a clean, sealed edge.
Because the edge is sealed rather than sewn, there is just one flat layer of fabric, with no folds and no thread for moisture to sink into. Up close, it looks like this.
What seamless means in your bathroom
- No seams for mold. With no folded hem, water and bacteria have nowhere to collect.
- Dries quickly. Water runs off the flat edge instead of soaking into a hem, so the edge dries with the rest of the curtain.
- A clean, flat edge. Fibres fused at the cut stay neat and let the curtain hang straight.
Built on a fabric made for water
A seamless edge works best on a fabric that doesn't hold water in the first place. Two more technologies work alongside it.
- AiryDry 150D™. A high-density 150-denier weave at a light 115 g/m². The tight weave sheds splashes, so you don't need a liner, and the light weight means less water held and faster drying.
- WetZero™. A water-repellent finish on both sides of the fabric. Splashes from the shower side and drips from the room side both bead up and run off, stains have a harder time settling in, and the curtain doesn't cling to you while you shower.
AiryDry 150D™ weave with WetZero™ on both faces: water beads up on either side instead of soaking in.
On the real fabric: water beads up and rolls off instead of soaking in.
Made in Korea, loved in Korea
Our seamless shower curtains are designed and made in Korea. More than 400,000 have been sold on Naver Plus Store since 2020. The fabric passed antibacterial activity and harmful-substance tests in 2024 at FITI Testing & Research Institute in Seoul, and OneSevenNine is a registered trademark in Korea and the United States.
Keep it fresh
To look after the fabric and its finish, hand wash gently in lukewarm water with a mild detergent, don't wring it, and let it dry in the shade. Machine washing isn't recommended, even on a delicate cycle.
