# Ultrasonic Sewing Sound Waves to Melt Fabric Together By Hayley Grieve | Published 2008-08-29 | Lifestyle Source: Trend Hunter, https://www.trendhunter.com/trends/clothes-without-thread-ultrasonic-seam-technology References: [nike](http://www.nike.com/index.jhtml?l=nikestore,pdp,_pdp,gid-97457/pid-97455) The sophistication of machinery used in the apparel industry is growing exponentially. The use of ultrasonic “sewing” machines has made it possible to piece garments together without a trace of thread or needles. Ultrasonic bonding uses high frequency sound waves to essentially melt together two fabric edges. The result is a clean and smooth seam that can lie perfectly flush with the skin. The technology at this point is expensive and slower than normal stitching, but this hasn’t stopped big sports apparel brands such as [Nike](https://www.trendhunter.com/trends/innovation-efforts) from shoveling in money for cool innovation developments. Check out this completely thread-less Nike Revolutionary Sports Bra that retails approximately $70. Even the hook adjusters on the back have dodged sewing. The whole world is also aware of the [Speedo](https://www.trendhunter.com/trends/ocean-flex) LZR suit after the Olympics, which uses a type of bonded/threadless seaming technology. Keep an eye out for this technology on the shelves this year as manufacturers try their hardest keep products looking top-notch sleek and streamlined. ## Trend Insights (Trend Hunter) - Score: 2.0/10 - Popularity: 35% | Activity: 18% | Freshness: 8% - Audience gender: 10% men, 90% women - Primary generations: Millennial, Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Lifestyle](https://www.trendhunter.com/lifestyle) > [Sports](https://www.trendhunter.com/sports) ## Key Themes ### Why This Trend Is Growing - **Ultrasonic Bonding:** Adoption of high frequency sound waves in production processes is a disruptive innovation opportunity for apparel and textile manufacturers. - **Thread-less Garments:** Development of thread-less garment designs is a disruptive innovation opportunity for fashion and sports apparel companies. - **Sleek Seaming Technology:** Advancement in bonded and thread-less seaming technology is a disruptive innovation opportunity for manufacturers of various products beyond fashion such as mattresses, upholstery, and automotive interiors. ### Industries Being Reshaped - **Apparel:** The adoption of ultrasonic bonding technology is a game-changing innovation for the fashion and sportswear industry. - **Textile Manufacturing:** The use of ultrasonic bonding technology presents opportunities for textile manufacturers to produce high-quality products with greater efficiency. - **Product Manufacturing:** The development of sleek seaming technology can be applied in the production of various products such as mattresses, upholstery, and automotive interiors, offering a new level of manufacturing quality. ## Related on Trend Hunter - [Ultrasonic Precision Knives](https://www.trendhunter.com/trends/c200.md) - [Fashionable Sewing Machines](https://www.trendhunter.com/trends/sewing-machine.md) - [Cable-Free Ultrasonic Cutters](https://www.trendhunter.com/trends/ultrasonic-cutter.md) - [Bulbous Ultrasonic Patches](https://www.trendhunter.com/trends/ultrasonic-patch.md) - [Ultrasonic Technology Kitchen Knives](https://www.trendhunter.com/trends/ultrasonic-kitchen-knife.md) - [App-Connected Sewing Machines](https://www.trendhunter.com/trends/singer-se9180.md) - [Versatile Ultrasonic Cleaners](https://www.trendhunter.com/trends/ultrasonic-cleaners.md) - [Vibrating Chef Knives](https://www.trendhunter.com/trends/seattle-ultrasonics.md) - [Hi-Tech Breast-Supporting Sports Bras](https://www.trendhunter.com/trends/techfit-control-bra.md)
