The invention relates to the technical field of textile, in particular to non-woven fabric for a tent. The non-woven fabric for the tent aims at the problem that the dyed portion of the tent is easy to damage under the outdoor condition, especially the cold condition. The method for manufacturing the non-woven fabric for the tent comprises the steps of (1) taking the non-woven fabric as base cloth, (2) dyeing the non-woven fabric in dye liquor, (3) printing the dyed non-woven fabric in printing paste, (4) coating the printed non-woven fabric with a waterproof layer, and (5) shaping the obtained non-woven fabric so that the non-woven fabric high in water resistance for the tent can be obtained.
