Embodiment 1
[0021] Such as figure 1 As shown, it is the non-woven fabric of this embodiment that can make the liquid permeate quickly and inhibit the rewetting. It is composed of the upper layer non-woven fabric 1 and the lower layer non-woven fabric 2. The non-woven fabric is prepared by carding and cross-lapping. The upper non-woven fabric 1 has a high degree of randomness, and the liquid can infiltrate in all directions along the surface of the non-woven fabric, and the infiltration speed is fast. The lower non-woven fabric 2 is prepared by ES polyphilic fibers through a non-woven direct laying process, and then stretched by a stretching machine to obtain the lower non-woven fabric 2, wherein the fibers are oriented and arranged along the machine direction to form a fixed Guide the water, the liquid reaches the lower layer and flows along the direction of the machine on the horizontal plane, which helps to guide and disperse better.

Embodiment 2
[0028] A method for preparing a non-woven fabric that can quickly infiltrate liquid and inhibit rewetting:
[0029] Step 1: Prepare ES monophilic fibers, weigh ES monophilic fibers of the required quality, and make them with an area density of 40g / m through non-woven carding and cross-lapping processes 2 fiber web A;
[0030] Step 2: Prepare ES multiphile fibers, weigh the ES multiphile fibers of the required quality, and then stretch the fiber web B under the condition of a pressure of 5N through the non-woven direct laying process to improve the fiber in the machine direction. Degree of orientation; after stretching, the fiber web is elongated to 1.3 times the original length; the surface density is 30g / m 2 fiber web B;
[0031] Step 3: Composite fiber web A and fiber web B by parallel laying, and place fiber web A above fiber web B to obtain a composite fiber web;
[0032] Step 4: Carry out hot rolling bonding and strengthening of the composite fiber web, feed the compos...
Embodiment 3
[0034] A preparation method of a non-woven fabric that can make liquid permeate quickly and inhibit rewetting:
[0035] Step 1: Prepare ES monophilic fibers, weigh ES monophilic fibers of the required quality, and make them with an area density of 40g / m through non-woven carding and cross-lapping processes 2 fiber web A;
[0036] The second step: prepare the ES multiphile fiber, weigh the ES multiphile fiber of the required quality, through the non-woven direct laying process, and then stretch the fiber web B under the condition of a pressure of 5N, and improve the machine The degree of fiber orientation in the direction; after stretching, the fiber web is elongated to 1.3 times the original length; the surface density is 30g / m 2 fiber web B;
[0037] Step 3: Acupuncture and reinforce the fiber web A to endow the fiber web A with a certain strength, and adopt one pre-acupuncture, one front acupuncture and one reverse acupuncture to obtain the upper non-woven fabric 1;
