The characterization of fluid flow in fibrous assemblies is essential to apply the absorbent materials such as wipe, sanitary and geotextile, and further to expand the end-uses of nonwoven fabrics. The liquid transport in fibrous materials is largely governed by the structure of fabrics. Thus, we have studied fluid transport behavior of needle punching laminated nonwovens (NPLN) with different processing conditions such as punching density and number of layers by a newly designed apparatus. The results obtained are as follows: the penetration force of fluid showed a decreasing trend with increasing punching density of NPLN, but increasing trend above $400;punches/cm^2$. The penetration velocity and penetration force increased due to the change of NPLN structure. The penetration velocity and penetration force in the NPLN fabrics decreased with increasing number of layers. Also, fluid penetration radius ratio in the NPLN fabrics generally decreased with increasing punching density, but increased above $400;punches/cm^2$. Meanwhile, the penetration radius ratio decreased with increasing number of layers.
