1. Principle of ultrasonic sewing
Ultrasonic sewing uses the high-frequency vibration friction principle to heat-bond fabric or other materials together. The high-frequency mechanical vibration generated by the ultrasonic generator is applied to the contact point of the material, and the heat energy generated by the friction makes the molecules of the material melt and combine rapidly, so as to achieve stitching or pressing. Unlike traditional needle and thread sewing, ultrasonic stitching does not need to penetrate the material, avoiding damage to the fabric.
2. The benefits of ultrasonic sewing
● No needle stitching, reduce material damage: ultrasonic sewing does not need to use needles and threads, to avoid pinhole damage to the material, especially suitable for some thin, soft or fine fabrics, such as non-woven fabrics, plastic fibers and so on.
● Efficient and fast: Compared with traditional sewing methods, ultrasonic sewing is faster. Because it is directly hot bonded materials through vibration, there is no need for complex processes of coils and needles, so the production efficiency is greatly improved.
● Durable: The seams formed by ultrasonic sewing are more solid than the traditional needle and thread stitching, the seams have strong tensile strength, and the seams have no pores, which can achieve higher sealing.
● Environmental protection and pollution-free: Ultrasonic suture does not require any glue, stitches or chemical adhesives, reducing the use of pollutants, and the production process is environmentally friendly and efficient.
● Beautiful and neat: the stitching lines are neat and smooth, no need to do trimming, suitable for product processing requiring high standard appearance quality.
3. Application and benefits of ultrasonic sewing
● Clothing manufacturing: Especially in the fields of waterproof, seamless underwear, outdoor clothing, etc., ultrasonic sewing can greatly improve production efficiency, while reducing the damage to the material by stitching, and maintaining the softness and comfort of the clothing.
● Non-woven products: such as disposable medical protective clothing, masks, surgical gowns, etc., ultrasonic sewing can provide needle-free suture technology to ensure the sterility and high sealing of products.
● Home textile products: such as bed sheets, curtains, etc., through ultrasonic sewing, seamless design can be achieved to improve the durability and beauty of the product.
conclusion
Ultrasonic sewing brings efficient, environmentally friendly and loss-free solutions to the modern clothing and textile industry. By reducing physical damage to materials, improving production efficiency and optimizing stitching quality, ultrasonic sewing technology is gradually becoming an important tool in the textile manufacturing industry.
