PURPOSE: A manufacturing method of non-woven fabric having high density and excellent tearing strength is characterized by using high shrinkage conjugate single fiber, not needing to elute and being economical. CONSTITUTION: The manufacturing method of the non-woven fabric comprises the next steps: spinning two different polymers to manufacture conjugate single fiber; carding and needle-punching the single fiber to manufacture the non-woven fabric; and then treating the non-woven fabric with hot water or with dry heat to shrink as 10-50% and to increase separation. The polymer A has high shrinkage. The polymer B has normal shrinkage. Conjugate ratio of the polymer A and the polymer B is 85:15 - 50:50 of weight ratio.
