As an embodiment of the present invention, the cross-sectional area of the through-hole 3 at the end far away from the hydrophilic layer 21 is larger than the cross-sectional area near the hydrophilic layer 21. Through-hole 3 sets to big-end-up's structure, is favorable to the water conservancy diversion to refuse the liquid on the surface course 1 and reduces the anti-infiltration of hydrophilic surface course 2 liquid, and the sectional area that hydrophilic layer 21 one end was kept away from to through-hole 3 is greater than the sectional area that is close to hydrophilic layer 21 promptly and is close to the aperture of the position of refusing liquid on the surface course 1 big, and the aperture that is close to hydrophilic surface course 2 is little, makes liquid from last pressure less when down permeating, otherwise, from the following pressure is great when up permeating. Preferably, the through holes 3 are circular and are uniformly arranged on the water-repellent surface layer 1. The through holes 3 can also extend to the middle of the hydrophilic surface layer 2 slightly, which is beneficial to the quick absorption of the liquid by the hydrophilic surface layer 2.
As an embodiment of the present invention, the water repellent layer 11 is made of a material treated with a water repellent oil agent; the hydrophilic layer 21 is made of a material treated with a hydrophilic oil agent.

Compared with the traditional single-component fiber material, the sheath-core type bi-component fiber material has softer and more comfortable hand feeling, has silky smooth feeling and improves the comfort level of products. The thin net formed by compounding multiple layers of single fibers can improve the phenomenon that the strength is poor and the cloth cover is easy to have the thin net, and is beneficial to further improving the product quality. On-line compounding is a common means of compounding single-layer fibers into multi-layer fibers in the textile industry. Specifically, the water repellent surface layer 1 and the hydrophilic surface layer 2 are carded into a thin net consisting of single fibers through a double carding machine, and the thin net is subjected to online composite treatment through hot air reinforcement of an oven, wherein the temperature of the hot air reinforcement is 130-155 ℃.
As an embodiment of the present invention, the sheath layer of the sheath-core bicomponent fiber material is a polyethylene material, and the core layer is any one or a combination of two resin materials, i.e., a polypropylene material and a polyester material. The leather layer is made of polyethylene material, so that effective adhesion can be realized by using lower temperature and pressure, and the product has good hand feeling; the core layer is made of polypropylene material and polyester material, so that the strength of the non-woven fabric product made of the sheath-core bicomponent fiber can be improved compared with that of a common product, and the product has good mechanical properties.
As an embodiment of the present invention, the proportion of the water-repellent fiber net in the water-repellent surface layer 1 is 40%, and the proportion of the hydrophilic fiber net in the hydrophilic surface layer 2 is 60%. The proper proportion of the water repellent fiber net and the hydrophilic fiber net can maintain the balance between the absorption capacity and the weight of the product, and the higher the proportion of the hydrophilic surface layer 2 is, the more water is absorbed, the heavier the product is, and the higher the possibility of reverse osmosis is; the dryness can be improved by selecting the water repellent surface layer 1 and the hydrophilic surface layer 2 in a proper proportion, and the material utilization rate is improved.
As one embodiment of the present invention, the first skin-friendly layer 12 and the second skin-friendly layer 22 are made of a material having a grammage of 20g/m2-30g/m2The hot air non-woven fabric material of (1). Gram weight of 22g/m230g/m2The hot air non-woven fabric material belongs to a hot air non-woven fabric material with low gram weight, is small in thickness, can make the product more portable, and improves the comfort.
