NONWOVEN FABRIC

摘要

A nonwoven fabric alternately formed on its upper surface with crests and troughs extending in parallel to one another in one direction to prevent bodily fluids from staying in the crests. Short fibers 11 of thermoplastic synthetic resin are fusion bonded to one another to form a nonwoven fabric 1. The nonwoven fabric 1 is formed on its upper surface 2 with crests 6 and troughs 7 extending in parallel to one another. The crests 6 include first crests 6a having a uniform height dimension from a lower surface 3 of the nonwoven fabric 1 and second crests 6b having a uniform height dimension from a lower surface 3 of the nonwoven fabric 1 which is smaller than the height dimension of the first crests 6a. Density of the nonwoven fabric 1 gradually increases in the order of the first crests 6a, the second crests 6b and the troughs 7. The first crests 6a are formed so that the density of the first crests 6a remains lower than the density of the second crests 6b even when the first crests 6a are compressed toward the lower surface 3 until the first crests 6a becomes flush with the level of the second crests 6b.
