    I don't like "submarine" PR articles like this, because I feel like the author didn't ask any of the obvious questions around this zipper:

    1. No closeup pics of how the zipper is actually sewed onto fabrics.

    2. Is this design more likely to tear fabrics than a traditional zipper? A video another commenter linked made it look more fragile to me, but I don't know.

    3. The biggest issue with any zipper is snags. This design looks like it would be a lot more likely to snag, but maybe not.

    4. As other commenters mentioned, can it be repaired without special equipment?

    I'm not saying this design is good or bad, just that this puff piece article didn't ask any of the immediate questions I had.

      Agreed

      > Its dominance comes from an unusual level of control: YKK manufactures its own machines, designs its own molds, and even spins its own thread. That self-sufficiency lets it experiment in ways competitors can’t, turning a mundane component into a field for continuous innovation.

      I thought the point was that there hasn’t been any innovation??

  • behnamoh 5 hours ago

    > That incremental progress mirrors YKK’s founding philosophy, the “Cycle of Goodness.” The principle—that no one prospers without benefiting others—has supposedly guided the company for decades. It’s visible in its other micro-improvements: corrosion-resistant alloys, sound-dampened sliders, recyclable polyester tapes. AiryString continues that tradition, shrinking the zipper’s physical and environmental footprint at once.

    This is alien to SF AI startups and patent trolls.

    • edelbitter 4 hours ago

      Having your customers suddenly require proprietary machinery (only sold/licensed by you) to unlock the full potential of your upgraded product line.. does seem compatible with the SF startup way of thinking.

      • beloch 4 hours ago

        It will be interesting to see what they do next.

        The SF approach would be to lock down every aspect of the new zippers with as much proprietary BS as possible for as long as possible, charging high fees the whole time and quite likely causing relatively poor market penetration. Relatively few people will pay $50 extra for a thinner zipper on a typical jacket. To combat this, one SF approach might be to pump out ads and branding to to make the new zipper a status symbol.

        e.g. Will we start to see fashion designers paid to highlight the new zippers on their products rather than hiding them behind flaps or in folds? Are Brando biker jackets about to trend again?

        On the other hand, YKK might simply do what they've been doing for the last century: Obliterate the competition by doing what they do better and cheaper. This is how they took the market from manufacturer's like Talon. They might maintain control of their new zipper tech with patents, etc., but they might also make the tooling affordable and try to maximize uptake by manufacturers.

        I have a vintage reproduction of a 1920's cafe racer with a Talon zipper on it. That thing needs to be babied. Zip it up wrong and the slide will bend, teeth will stop engaging, etc.. If you want a jacket that you'll think twice about zipping up (e.g. "Am I really so cold it's worth it?"), get something with a vintage Talon zipper. The first thing that stood out to me as a falsehood in this article was the claim that this is the first upgrade to the zipper in a century. YKK has been quietly making them better and better that whole time.

        They surely learned something from Microsoft.

      • dingnuts 4 hours ago

        yes, and the fact that the article brushes over this and is so breathless -- it's an ad, right?

        My first question was: if they remove the tape, how do you affix it to the garment? and you're right, the article glides over the fact that this company, which is largely a monopoly, is creating garments that will apparently require a proprietary device to repair.

        It's like a Juicero ad, but for your fly. I'm good.

        • calmworm 4 hours ago

          But its not anything like a Juicero ad is it? They are not halting production on all other zippers or charging you a monthly zipper refill fee… but adding a new product line with more and different possible uses. An innovative new design for a product most don’t think twice about. It’s pretty cool, really.

    • ardit33 4 hours ago

      not a productive comment. The web is made and run by myriad of frameworks, that were developed open source by startups, or folks that worked in tech that wanted to improve things bit by bit and wanted to share to the community.

      Tech in general is the much more open industry compared to any other (cars, biotech, etc), and it is uniquely where closed sourced frameworks have a har time to succeed.

    • kakacik 4 hours ago

      None of them will be around for long, and if yes only by pure unintended accident.

      But dont blame the participants, they fight for money in system setup for them. If people will reward clearly more moral businesses, over time even the most hardened sociopath will pick up the cues.

      If you want to hate something, hate how uncaring an average person is, driven by simple, easy to manipulate emotions, not fighting primal urges even if they drive them off the cliff, or even caring more deeply about themselves, who they are and where they go.

      • XenophileJKO 4 hours ago

        Isn't it kind of the opposite? Taking a ethical stance is often superficially suboptimal at maximizing personal value. Obviously moral frameworks vary by culture, but commonly involve setting aside some amount of self interest.

        The same is true of a business, primarily driven by the executives and carried out by rank and file.

    "Major Upgrade" for the fast, disposable fashion crowd.

    Major downgrade for maintainability and ability to repair.

    This "upgraded" zipper will be impossible to replace if broken at home, by hand or with a machine, or even at a typical professional repair shop. YKK documents say a "dedicated AiryString® sewing machine" is required.[1]

    • OptionOfT 6 hours ago

      Fabrics have gotten a lot thinner, and thus develop holes a lot more quickly.

      I have t-shirts from 2010 which are faded but have 0 holes. Whereas t-shirts I bought half a year ago have holes in them.

      Also, you mentioning the inability to repair stuff at home makes me sad. My mom, 72 year old, repaired my nephew's jacket the other day. Brand new zipper.

      The machine in that PDF you shared makes me feel YKK is going in the direction of Apple. They supply the parts and the manufacturing device.

      You do something they don't like? Sewing machine turns off.

      • emptybits 6 hours ago

        Yes. Also at the above link:

        "All AiryString® part sales and leasing of dedicated sewing machines are conducted between YKK and the customer.

        One of the little things I find most satisfying about getting old is hearing the same proclamations about quality going to shit today that I heard when I was much younger, only now the supposedly-good baseline of the comparison happened well after the complaints I grew up hearing. I, too, want everyone to get the hell off my lawn.

              The comment means "you throw away the shirts with holes, so obviously any shirt you have from 2010 has no holes". Unless every single new shirt the GP has has holes in it (which they don't), we can't draw any conclusions from this, except "some shirts from any year last a long time and some don't".

      • portaouflop 5 hours ago

        The fix is easy: Don’t buy new clothes from fast fashion brands or stores.

        If you only buy quality from small stores and independent designers you still get the same quality you got 15 years ago. Sure it’s 2-3 times the price but it’s worth it.

        • Gud 4 hours ago

          I don’t know if it’s that easy.

          I have a few favourites t-shirts I rotate around. My H&M Iron Maiden t-shirt for $20 has surpassed much more expensive t-shirts by a long shot.

          • portaouflop 6 minutes ago

            It also helps to avoid synthetic fabrics in my experience.

            But you are right it’s not that easy…

    • Retr0id 6 hours ago

      It might be more challenging but I don't see why you couldn't also sew this by hand.

    • constantcrying 5 hours ago

      >Major downgrade for maintainability and ability to repair.

      But it seems the exact opposite is true. These zippers should be easily removable, leaving the fabric mostly intact. After that you can put in a normal zipper.

      • pavon 4 hours ago

        This looks much harder to seam-rip to me, as the stitching is going between the individual zipper teeth.

        • constantcrying 4 hours ago

          But you can just cut it off entirely, with minimal losses to the fabric, which is preferable to pulling out the seams, which will leave damaged fabric behind.

    Anyone interested in zippers, or, more significantly for this website, how new technologies are invented, adopted, and mature, should read "Zipper: An Exploration in Novelty" by Robert D. Friedel [1]

    YKK is kind of one of the heroes of the story. The zipper was pioneered by the U.S. company Talon Fastener, which was acquired and parted out in the 1970s. YKK bought the legacy machining for manufacturing zippers and went on to dominate the global market.

    The excellent Avery Trufelman (formerly of 99% Invisible) has been running Articles of Interest (<https://www.articlesofinterest.co> and <https://articlesofinterest.substack.com>), a surprisingly interesting podcast about clothing and and culture and so much more. The Ivy League episodes are a great example of what they're about.

    Over the summer, they had an episode about the zipper—<https://articlesofinterest.substack.com/p/new-episode-zipper...> and <https://www.articlesofinterest.co/podcast/episode/2b1f2292/z...>—which is well worth a listen.

  • Danieru 7 hours ago

    This is a big deal for YKK.

    Until a few years ago they had a hold on the upper end of the market. The chinese competitor's quality was unreliable enough that clothing manufacturers were willing to pay a premium to ensure a failed zipper does not trash a garment. That situation has been changing, and chinese companies are offering zippers which are getting used on progressively higher end products.

    By releasing a new product with substantial changes and thus patentability they can buy a few decades at the top of the market. I suspect this technology has been in development for a long time, and held back until competitors were threatening the premium traditional zipper market.

    "Please be aware that when using AiryString® on fabrics with the following characteristics, there are concerns that the zipper may come unstitched, roll into the slider, or not be strong enough. ◇ Fabrics with notably low slippage resistance ( woven fabrics: fabrics with low thread counts, knitted fabrics: fabrics with loose tension). ◇ Fabrics with low friction resistance ◇ Fabrics with large bumps ◇ Shaggy fabrics"

    • jsolson 6 hours ago

      That would make sense.

      My first thought was "Arc'teryx will probably adopt this immediately." They (and similar brands) are already pushing as hard as they can on seamlessness or very very tight seams.

  • aydyn 5 hours ago

    The upgrade I want is a two way zipper that actually works well. Current two way zippers suck, so most jacket manufacturers have abandoned them completely.

    Honestly dont see the point of this "upgrade". Normal zippers work fine.

  • dan-robertson 2 hours ago

    This feels to me like the right place to be trying to innovate. Zippers tend to be pretty good for the most technical clothing (and some other cases that demand textiles). In ordinary settings, I find more and more that I prefer pullovers, buttons, or other traditional fastening/closure mechanisms.

  • jasonthorsness 7 hours ago

          It's not worse; it's different, and better for some applications. Specifically when high flexibility and/or sleek appearance are valued above cost and durability. One example that immediately comes to mind is zip-up pockets in athletic wear.

    • dewey 7 hours ago

      > Their new AiryString zipper looks ordinary at first glance. Then you realize what’s missing: there’s no tape. That absence transforms everything. Without the woven fabric that normally flanks the teeth, the AiryString is lighter, sleeker, and far more flexible.

          No, from the article:

          "Without them, YKK had to rethink every step of production

          • card_zero 6 hours ago

            Redesigned to attach to the fabric in a different way, I think.

            Usually the teeth are attached somehow to the fabric strip. I think the strip has a ridge at the edge where the teeth go, and the teeth are clamped over that ridge to hold them in place. Then the fabric strip is easy to sew onto a garment. It looks like the new design has only the ridge, hence it's called a string, and is hard to sew onto a garment.

    • WesolyKubeczek 7 hours ago

            I'm in my 40s and don't think I've ever replaced a zipper. I'm sure a handful have broken over my lifetime, but never on something nice enough to be worth repairing. I wouldn't buy clothing based on the possibility of this (to me) extreme edge case.

        You can. You’d just attach a fabric tape zipper and the clothes would stop being as flexible. So you get the best of both worlds: a fancy zipper to start with that delivers increased performance and then you remove the performance and have an old zipper placed in there.

        You just get an extra semi rigid fabric track when you repair. Your clothes should still work.

    So, uh, how is it attached to the garment? They talk about specialized sewing equipment, so it’s not bonded (although for polymer-based outerwear solvent bonding seems like the ultimate end-point)… but there’s no thru-holes or other obvious attachment points.

    • opan 3 hours ago

      I similarly had an issue with stuff falling out of my pockets which made me get pants with zipper pockets. In the end I was disappointed. I had some pants and shorts from Fjallraven and the zippers on the pockets all failed in under a year from what I recall. I ended up switching to all Duluth Trading Co. pants/shorts. These do NOT have zipper pockets, but they DID solve my problem, somehow. The pockets are deeper and perhaps a better shape. I've hung upside down in an inversion table, pockets stuffed full with what some would call an excessive EDC, and nothing falls out.

      I would say avoid excercise-y pants/shorts and pajama pants, they have particularly bad pockets. That alone helped me quite a bit. I went from more lounge-y wear to dressing like a tradesman on the average day. The Duluth Trading pants are a lot more comfortable than any blue jeans I've worn before, as well as more durable and with more pockets. I have seen some other brands with similar design but can't recall the names. I just know I got some pair from Menard's or Fleet Farm once as a gift and the pocket layout was surprisingly identical to my Duluth Trading pants. I didn't like them as much, but I don't remember any specific major flaws either. Mostly including that tidbit to sound less like an ad for DT.

    • bobthepanda 5 hours ago

      In the grand scheme of textiles, which actually are a major source of environmental harm, it’s probably the choice of textile that would impact emissions the most. Cotton is one of the most water hungry crops we grow and resulted in the drying up of the Aral Sea; animal products have all the emissions associated with animal farming; and synthetics are generally petroleum based.
