The invention relates to a non-woven material and a processing method thereof, in particular to a high-strength easily-degradable linen-fiber non-woven fabric and a production method thereof. Mainly aiming at the disadvantages that the common non-woven fabric is poor in strength and durability and chemical-fiber non-woven fabric is difficult to degrade and the like, the invention invents the linen-fiber non-woven fabric which is high in strength, good in durability and easy to degrade. The invention adopts a main technical proposal that the high-strength easily-degradable linen-fiber non-woven fabric comprises the following components in weight percentage: 50 to 70 percent of linen fibers and 30 to 50 percent of ES fibers. The processing method of the linen-fiber non-woven fabric comprises the following processes of degumming, opening, forming webs, strengthening and drying fiber webs.
