[0024] The working principle of an oil-resistant and water-repellent elastic nonwoven fabric based on Example 1 is:

[0025] First, the first wax emulsion 21 is chemically bonded with the fibers of the non-woven fabric 1 to make its surface smooth, reduce the friction coefficient, and reduce the possibility of pilling of the non-woven fabric 1.
