FLATKNIT® is a soft and flexible zipper with a narrow tape that keeps the silhouette of your clothing. It is indispensable when tailoring clothes from light and thin fabrics.
When sewing on the narrow FLATKNIT zipper, you only need to sew one straight stitch directly over the outer fabric, no other zipper manipulations are needed, thus the sewing process can be speeded up.
The thickness of the fabric at the place where the zipper is sewn in becomes thinner, which makes the silhouette of the garment more accurate.

The modern clothing and textile accessories market requires not only aesthetics, but also functionality. That is why leading manufacturers strive to introduce innovations that improve the comfort, durability and appearance of products. One of such revolutionary solutions was the FLATKNIT soft zipper from YKK – a unique development that combines a high-tech approach and the desire for maximum convenience. This zipper has already gained recognition among designers, clothing manufacturers and consumers around the world.
What is FLATKNIT from YKK?
FLATKNIT is a soft, almost invisible to the touch zipper created using flat knit technology. It is distinguished by a special method of integration into the fabric: instead of sewing the zipper to the product, it is “woven” into the fabric. This makes it incredibly flexible, thin and almost invisible on the finished product.
YKK is a world leader in the production of fasteners, including zippers, buttons and other types of fittings. Thanks to its own research centers and high-precision production lines, YKK was the first to bring to market the FLATKNIT zipper, which combines style, convenience and reliability.
Main advantages
- Softness and comfort
The main difference is weightlessness and no pressure on the skin. Unlike classic zippers, FLATKNIT is completely imperceptible to the body, even if the product fits tightly.
- Ultra-thin profile
The zipper practically merges with the fabric, not standing out under clothing. This is especially important in the production of sportswear, underwear, medical clothing, sleepwear and everyday items.
- Flexible and stretchable
Thanks to the braided structure, FLATKNIT bends easily, does not break and does not lose functionality even with active movement.
- Aesthetic appearance
Without protruding elements, rough seams and bulky structures. The YKK zipper looks minimalist and modern, emphasizing the style of clothing, rather than distracting from it.
- Increased wear resistance
Despite its softness, this zipper is designed for repeated use and perfectly withstands washing, bending, stretching.
