YKK FASTENING CREATION for 2025 Exhibition: FLATKNIT®AquaGuard® Flexible Thin Watertight Zipper

ApparelX News editor team visited “YKK FASTENING CREATION for 2025” held at the Tokyo venue in Ryogoku on November, we had a lot of fun at the exhibits and hands-on booths where we were able to touch and feel new products and products that we usually don’t see.

This time, among the many new products, AparelX News would like to introduce the FLATKNIT watertight zipper!

FLATKNIT®AquaGuard® zipper

Aquaguard® is a watertight zipper based on FLATKNIT®, which is a knitted tape with woven elements, to achieve lightness, thinness, and softness.

Compared to regular AquaGuard®, it reduces stiffness and is suitable for lightweight clothing for sports and outdoor activities.

It is not completely waterproof.

There were samples of regular AquaGuard® and FLATKNIT®AquaGuard® to compare!

The regular AquaGuard® film felt less filmy and more supple.

When comparing colors, the colors of FLATKNIT®AquaGuard® have less of a thicker matte look than regular AquaGuard®, perhaps due to the thinner film, and the colors are softer with a shiny matte look and texture.
It is a watertight zipper, but the colors are pretty, so it would be interesting to choose one based on functionality, color and texture design.

We were also able to actually see and touch the flower motifs in the comparison exhibit.

It is waterproof even if it is thin.

It wouldn’t be able to tell much difference from the outside,but the FLATKNIT®AquaGuard® zipper is definitely softer and more supple, so the folded part of the flower is more compact and easier to hold together.

The normal AquaGuard® zipper is more firm, so the bent part seems to spread out more easily.

ApparelX recommend product

The FLATKNIT®AquaGuard® zipper introduced up to this point is now available as a new product on ApparelX!

The color image in the reference material is the same as that of the regular watertight zipper, but FLATKNIT®AquaGuard® gives the impression of a softer color with less overall filminess.

Conclusion

While regular FLATKNIT® is often used for ladies’ items, FLATKNIT®AquaGuard® is recommended for sportswear/outdoor items due to its functionality.

For example, if Flatknit zipper was attached to a pocketable parka that can be folded compactly and easily stored.
