Embodiment Construction
[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings, but it is not intended to limit the protection scope of the present invention.
[0024] Such as Figure 1-3 As shown, a dumbbell-shaped pressure point composite non-woven fabric includes a composite surface layer 1 and a bottom layer 2, the surface layer 1 is a hot-air non-woven fabric, and the bottom layer 2 is a hot-air non-woven fabric. Ultrasonic thermal bonding and embossing through dumbbell-shaped flat points 9, and after ultrasonic thermal bonding between the surface layer 1 and the bottom layer 2, several pearl-shaped bumps 3 are formed, and between the surface layer 1 and the bottom layer 2 through dumbbell-shaped After the flat point 9 is embossed, several dumbbell-shaped shaping points 8 are formed, and there is a dumbbell-shaped shaping point 8 between every four adjacent pearl-shaped swelling points 3 . The length*width of the dumbbell-shaped shap...
