The invention provides a hot air non-woven fabric and a preparation method and application thereof.The preparation method comprises the steps that firstly, 2D * 38MM PLA fibers and 2D * 38MM PE/PET composite fibers are split in a first splitting machine and a second splitting machine respectively, the opened fibers are fed into a cotton blending box for cotton blending, fully-blended fibers are obtained, then the fully-blended fibers are carded into monofilaments, and the monofilaments are formed; and finally, the obtained cotton web is sequentially subjected to bonding, ironing, cooling, rolling and punching treatment, and the hot air non-woven fabric can be obtained. The surface of the hot air non-woven fabric is soft and smooth, and the hot air non-woven fabric can release lactic acid components in a wet state and has a skin care effect. 本发明提供一种热风非织造布及其制备方法和应用，所述制备方法首选将2D×38MM的PLA纤维和2D×38MM的PE/PET复合纤维分别在1号开纤机和2号开纤机进行开纤，将开松好的纤维送入混棉箱进行混棉，得到充分混合的纤维，再将充分混合的纤维梳理成单丝状，铺成棉网，最后将得到的棉网依次进行粘合、烫平、冷却、收卷和打孔处理，即可得到所述热风非织造
