The invention discloses a nonwoven material prepared through discontinuous type functional treatment and a preparation method thereof. The nonwoven material basement is processed through discontinuous type functional treatment to form functional areas which are arranged discontinuously. The preparation method of the invention can be used to perform various functional treatments to nonwoven material basement, the equipment modification is easy, the investment is low, the preparation method can not conflict with the production technology of the common nonwoven fabric, the existing equipment and process can also be used; and therefore, the method is easy to realize and the production cost is low. The nonwoven material prepared through discontinuous type functional treatment of the invention can have different functions; the material can be freely cut into multiple pieces with small breadth along the transverse breadth direction, for example the nonwoven material with small breadth in the arrangement manner of 'non-treatment + functional treatment + non-treatment' can be prepared; and the amount of raw material used in functional treatment can be reduced, the cost is saved, and the bad effects of some raw materials to human body can be lowered.
