SCIENTIFIC ANALYSIS OF ULTRASONIC METHOD OF SEWING FABRICS AND DEVELOPMENT OF ADVANCED SEWING MACHINE

Abstract

Ultrasonic welding (UW) emerges as a standout technique for efficiently joining thermoplastic materials, offering a blend of high strength and cost-effectiveness. This method, gaining traction for its advancements, demands careful consideration of application-specific requirements to unlock its full potential. This review delves into the latest strides in ultrasonic welding for fabric joining, spotlighting the influence of key parameters like duration, pressure, and vibration amplitude on joint quality. It underscores the complexity of optimizing these factors to enhance joint durability, strength, and aesthetics. Comparing ultrasonic welding to traditional methods, its advantages—such as speed, economy, and eco-friendliness—are evident, despite some material limitations. This paper presents an exhaustive analysis of ultrasonic welding's current landscape and its promising trajectory for innovation. It suggests that optimizing welding parameters and innovating energy guides could further refine joint quality, distributing energy more evenly across the weld. In summary, ultrasonic fabric welding stands out for its efficiency and reliability in joining diverse thermoplastic composites. Its track record suggests significant potential for broader application, from textiles to advanced composites, championed by its rapid processing, affordability, and strong, binder-free joints. This review not only highlights ultrasonic welding's advantages but also its adaptability and future in manufacturing, making a compelling case for its continued adoption and development.[1]
