る。2. Description of the Related Art In recent years, in an absorbent article having a three-layer structure comprising a liquid-permeable topsheet, an absorbent and a liquid-impermeable backsheet, an absorbent sheet is used to absorb urine and the like quickly into the absorbent. It has been practiced to attach a so-called transfer sheet between the bodies. The transfer sheet is made of a bulky nonwoven fabric or the like, and serves to improve the absorption speed and the absorption amount of the absorbent article by diffusing and transmitting excrement such as urine penetrating into the absorber from the topsheet. However, it is recognized that the transfer sheet described above does not function sufficiently due to the closing of the gap due to the pressure at the time of wearing, the swelling of the absorber, and the excessive joining due to hot melt or the like at the time of production.

A fold is formed on the hydrophilic non-woven fabric, and this is used as a transfer sheet provided between the surface material and the absorber. The formation of the folds is performed by attaching a plurality of stretched elastic members to the base non-woven fabric to form a gather, or by mixing heat-shrinkable fibers during the manufacture of the base and shrinking it after manufacture. Can be. The size of the transfer sheet is preferably equal to or slightly smaller than that of the absorber. Furthermore, if three-dimensional gathers are provided upright on both sides of the transfer sheet or on the inside of the surface material corresponding to the inside of the transfer sheet, lateral leakage of the liquid on the surface material can be prevented, and it can be more efficiently transmitted to the absorber. Can be done.

(A) and (B) differ in the way the transfer sheet is folded. When the folds are formed by gathering, the shape of the gather may be any of a straight shape, a curved shape (wave shape, a sinusoidal curve), or a combination thereof. FIG. 3 (A) to (F)
Are examples of their arrangement. The length of the gathers may extend over the entire length of the transfer sheet, or may be intermittent as shown in FIG. When the pleating means is formed by shrinking, a small amount of heat-shrinkable fiber is mixed with the raw material of the hydrophilic nonwoven fabric. The heat-shrinkable fiber can be produced from a vinyl chloride resin, a vinylidene chloride resin, polyethylene, polypropylene, polyester, polystyrene, or the like, and is preferably produced by drawing low-density, low-melt-index polyethylene. The blending amount can be appropriately changed depending on the desired degree of shrinkage, but is usually 30% or less, which is such that the hydrophilicity of the nonwoven fabric is not significantly impaired. In order to provide three-dimensional gathers at portions of the surface material corresponding to both ends of the transfer sheet, an elastic member is sandwiched between nonwoven fabrics and raised.

かつ横漏れがなく、満足すべき結果が得られた。Example 1 13 thin rubber threads were adhered to a nonwoven fabric having a length of 190 mm and a width of 130 mm, and shrunk by about 30% in the length direction to produce a pleated transfer sheet. This is inserted between the surface material and the absorber, and elastic members are sandwiched between non-woven fabrics at the parts of the surface material corresponding to both ends of the transfer sheet, and a three-dimensional gather with a height of about 5 mm is provided in a standing shape to provide a disposable diaper for adults. completed. When a test was conducted using simulated excrement, the absorption speed increased and the absorption amount increased compared to the conventional transfer sheet-containing absorbent articles.
Satisfactory results were obtained with no side leakage.

大きい。As can be seen from the above examples, the absorbent article provided with the transfer sheet having the folds of the present invention has improved absorption capacity as compared with the conventional absorbent article. Advantages of the invention include a surface non-woven fabric that has little wet back (return of liquid), has good bumpiness due to the unevenness of the gathers being buffered by the surface material, has excellent cushioning properties, can make absorbent articles thinner. The product is of great industrial significance, for example, it is somewhat roughened to improve the fixability of loose stools and prevent leakage.
