Abstract:
1. A topsheet for an absorbent article comprising: a first layer disposed on the side of a wearer; and a second layer disposed on the side of an absorbent member, wherein the first layer and the second layer being partly joined together in densified joints, said densified joints being arranged in a spot pattern said spot pattern is in a checkerboard arrangement, and having protrusions and depressions on the side of a wearer, wherein said protrusions in the first layer are made by the formation of helically crimped fibers in the second layer and thermal shrinkage of the second layer, wherein the depressions contain the densified joints, wherein said first layer and said second layer each comprise a fiber aggregate, said first layer has fusion-bonded fiber intersections that are formed in the protrusions of the topsheet, and said second layer comprises said helically crimped fibers that include conjugate fibers consisting of two thermoplastic polymers have different shrinkage characteristics in an eccentric core-sheath configuration or side-by-side configuration, wherein said first layer has an apparent thickness (t wherein said first layer has a fiber density (d wherein said first layer and said second layer are in contact with each other in not only the joint areas but also other parts.
