Spunlace Non-Woven Fabric Ultrasonic Stitching
Ultrasonic Lace Stitching
Ultrasonic lace stitching uses an ultrasonic generator to convert high-frequency electrical energy into mechanical vibration. This energy is transmitted through a welding head to the non-woven fabric, causing the material’s molecules to vibrate and generate heat through friction.
As the vibration heats the material to its melting point, the non-woven fabric—due to its relatively slow heat dissipation—quickly melts, creating a bond that is nearly as strong as the original material. With proper design, these joints can be completely sealed.
By utilizing ultrasonic welding, there is no need for traditional needle-and-thread stitching, eliminating the inconvenience of frequent needle changes. This technology also avoids issues like thread breakage that occur with conventional sewing methods.
Additionally, ultrasonic technology enables precise, clean cutting and sealing of non-woven fabrics, allowing for customized stitching, edge binding, cutting, embossing, and more. Various rollers, molds, and cutting tools can be designed based on specific product needs, delivering superior results across different applications.
Ultrasonic Non-Woven Fabric Edge Binding Machine
The ultrasonic lace machine combines ultrasonic technology with a sewing-machine-like structure, where ultrasonic waves drive processing tools such as lace wheels, spot welding heads, and edge welding heads.
Since non-woven fabric is typically made from polypropylene (PP), ultrasonic welding is highly effective for bonding this material. It also works well with other synthetic fibers like polyester, nylon, spandex, and acrylic, making it a versatile solution for a wide range of textiles.
Applications of the Ultrasonic Stitching Machine
Ultrasonic stitching machines are widely used in industries that produce non-woven fabric products, such as the medical, daily necessities, packaging, automotive, decorative, and toy sectors.
Typical applications include lace for clothing, seat covers for cars, handle straps, shopping bags, face masks, surgical gowns, lampshades, filters, disposable products, protective clothing, and much more. This technology is especially beneficial for products made from non-woven fabrics, which are commonly used in these industries.
