  • the non-woven surgical dressing with enhanced visual tracking performance of the present invention is easy to use, and does not require expensive additional equipment and additionally equipped operators.
  • the effect of high visual enhancement makes the non-woven surgical dressing of the present invention easy to visually track, and it is also easier to find the non-woven dressing from the patient's body during the operation, and the risk of the surgical dressing being left in the patient's body is minimized.
  • the visual tracking strip 12 and retrieval handle 121 make counting blood-soaked surgical dressings easier and more accurate.
  • the cost of the non-woven surgical dressing of the present invention is superior to other conventional cotton fabrics for improved safety. Gauze surgical dressings are easier to be widely used in hospitals around the world.
  • the ultrasonic welding process enables the various components of the surgical dressing to be connected through automated production, such as the absorbent pad 10, the visual tracking strip 12, and the retrieval handle 121, thus subversively changing the current cotton yarn dressing industry that can only be used by sewing.
  • the traditional production process is used to connect the various components of the gauze surgical dressing.
  • the ultrasonic welding process is only suitable for spunlace or needle-punched absorbent non-woven materials containing rayon fibers, wood pulp fibers, cotton fibers, polyester fibers, polypropylene fibers or bamboo fibers, not for cotton gauze.
