Melt spinning non-woven material and production method and application thereof

A melt spinning non-woven material is characterized in that the weight of the non-woven material weights 35 to 500 g / m<2> and being obtained by a polymer slice being directly melting to spin and the spine being weaved into webs. The melt spinning non-woven material consists of superfine fibers and crude fibers, the crude fibers are used as a framework and the superfine fibers are filled into the framework to form a fiber web to form a thickness matching structure. The fiber web has one layer or more, and when the layer number of the fiber web is more than one, a thickness increasing or gradient structure is formed through a multilayer structure. By means of the optimization of raw materials and process, the melt spinning non-woven material and a production method and an application of the melt spinning non-woven material can control a fiber web structure of the melt spinning non woven material: the distribution of fiber finenesses is controlled in a reasonable range, the fiber web has a large amount of superfine fibers and a certain amount of crude fibers; the crude fibers being used as a framework and the superfine fibers being filled into the framework improve the fluffiness of the material, and the material can still maintain some recovery capability when in use; and the fiber web forms a structure with some gradients.
