An absorptive article containing a surface material comprising a combined non-woven fabric comprising at least two layers of a long fiber non-woven fabric and a short fiber non-woven fabric joined together and an absorbing body for retaining a body fluid is disclosed in which the short fiber non-woven fabric is composed of hot-melt-adhesive composite short fibers having at least two kinds of thermoplastic resin components of a high melting point component and low melting point component, and the hot-melt-adhesive composite short fibers are hot-melt-adhered together, the crossing angle of the short fibers at least preferably at least 45%, preferably at least 50% of the total contact points in the short fiber non-woven fabric are occupied by an angle of 60.degree. to 90.degree. in the analysis of the distribution of the crossing angle at the contact points of the fibers. An absorptive article is provided which is bulky and has a good hand feeling and touch, a good permeability of body fluids such as urine, blood, sweat, etc., a superior spot-absorption, a dryish feeling, and the property of a small back flow of the body fluids.
An absorptive article containing a surface material comprising a combined non-woven fabric comprising at least two layers of a long fiber non-woven fabric and a short fiber non-woven fabric joined together, and an absorbing body for retaining a body fluid, said short fiber non-woven fabric being composed of hot-melt-adhesive composite short fibers having at least two kinds of thermoplastic resin components of a high melting point component and a low melting point component, said hot-melt-adhesive composite short fibers being hot-melt-adhered together, the crossing angle of said short fibers at at least 45% of the total contact points in said short fiber non-woven fabric being occupied by an angle of 60.degree. to 90.degree. in the analysis of the distribution of the crossing angle at the contact points of said short fibers wherein said crossing angle of 60.degree. to 90.degree. at at least 45% of the total contact points in said short fiber non-woven fabric is determined by measuring the smallest angle among four angles formed at the contact point of short fibers which are crossed.
