Quick-drying absorption core

A quick-drying absorption core, characterized by comprising an absorbent core body;

• the absorbent core body is longitudinally extended, defining a vertical direction, and laterally extended, defining a horizontal direction;
• the absorbent core body comprises an upper nonwoven fabric layer, a fluffy nonwoven fabric layer, and a lower nonwoven fabric layer;
• an upper surface and a lower surface of the fluffy nonwoven fabric layer are provided with super absorbent polymer;
• part of the super absorbent polymer is embedded within the pores of the fluffy nonwoven fabric layer, with the density of super absorbent polymer atop the fluffy nonwoven fabric layer diminishing in a stepwise manner from the longitudinal midpoint towards two ends of the fluffy nonwoven fabric layer;
• the upper nonwoven fabric layer is adhesively laminated onto an upper surface of the fluffy nonwoven fabric layer, while the lower nonwoven fabric layer is adhesively laminated onto a lower surface of the fluffy nonwoven fabric layer;
• the lateral width of the lower nonwoven fabric layer is greater by 8 mm to 25 mm than the lateral width of the fluffy nonwoven fabric layer;
• the lateral sides of the lower nonwoven fabric layer are folded upward and inward, adhering to the upper surface of the upper nonwoven fabric layer, and securing to the upper nonwoven fabric layer and the fluffy nonwoven fabric layer through heat pressing or ultrasonic welding;
• the longitudinal ends of the upper nonwoven fabric layer is securely joined to the fluffy nonwoven fabric layer and the lower nonwoven fabric layer through heat pressing or ultrasonic welding;
• two guidance channels are pressed into the longitudinal center of the absorbent core body, running in parallel along the vertical direction;
• the upper nonwoven fabric layer, the fluffy nonwoven fabric layer, and the lower nonwoven fabric layer are jointed securely at longitudinal center of the guidance channels by heat pressing or ultrasonic welding secures;
• the absorbent capacity of the absorbent core body follows a stepwise increment from one longitudinal end to the other, and then similarly decreases in a stepwise manner.
