Problems solved by technology

[0014] In summary, due to the structure and process differences between different fabrics, the unidirectional water-conducting weaving process and production equipment of woven fabrics and knitted fabrics cannot be directly used in the production of unidirectional water-conducting nonwoven materials.
At the same time, the cost of woven and knitted fabrics is relatively high, the fabrics are thick and heavy, some products contain chemical substances, which will affect human health, and are not suitable for disposable products and medical and health products
Moreover, the current realization of the water-conducting function of unidirectional water-conducting materials is limited to the vertical direction, and there is no example that can simultaneously realize directional water-conducting in the horizontal direction and vertical direction.

Abstract

The invention provides a nonwoven composite material with an oriented water guide function, and a manufacturing method thereof. The nonwoven composite material with an oriented water guide function is characterized by comprising a hydrophilic layer, a water repellent layer, and a mixed layer between the hydrophilic layer and the water repellent layer. The hydrophilic layer is formed by hydrophilic fibers. The water repellent layer is formed by hydrophobic fibers. The mixed layer is formed by the hydrophilic fibers and the hydrophobic fibers. Part or all hydrophilic fibers in the hydrophilic layer and part or all hydrophobic fibers in the water repellent layer are arranged along a certain direction, and arraying directions of the hydrophilic fibers and the hydrophobic fibers are the same. A horizontal surface and a vertical surface have the oriented water guide function at the same time, and oriented water guide effect is excellent.

Description

technical field [0001] The present invention relates to a method for preparing a directional water-conducting nonwoven material, in particular to a method for preparing a non-woven composite material with directional water-conducting functions in both the horizontal plane and the vertical plane. The directional water-conducting function in the horizontal plane and in the thickness (vertical) direction can be directly prepared by hydrophilic and water-repellent fiber materials, without any chemical finishing process, no pollution to the environment, and excellent comfort and health. The material has a wide range of uses and can be used in medical dressings, surface and drainage layers of diapers, and footwear substrates. Background technique [0002] In the field of wearing clothing, taking sportswear as an example, the human body will produce a lot of sweat during strenuous exercise. If the sweat cannot be discharged in time, the wearing comfort of the sportswear will be red...
