Absorbent commodity according to another embodiment of the invention, it comprises: liquid permeability top flat; Liquid-tight egative film; Be arranged between top flat and egative film for absorbing the absorber through the liquid of top flat; And be arranged in the surge layer that is delivered to absorber for the liquid of top flat will be seen through between top flat and absorber.This surge layer comprises laminate, and described laminate comprises the perforation nonwoven web and the nonwoven web without perforation that is laminated to its top side and/or bottom side without physics or thermal deformation.
In one embodiment, the gross area of these perforation is preferably 5% to 80% of the nonwoven web gross area.The diameter of perforation is preferably 2 millimeters to 30 millimeters.More preferably 5 millimeters to 10 millimeters of the diameters of perforation.The basic weight of the nonwoven web of perforation is preferably 20 grams every square metre to 400 grams every square metre.
According to the manufacture method of nonwoven web of the present invention, multiple perforation can be formed in nonwoven web under the condition that physical deformation or thermal deformation do not occur, increase with the fibre density that prevents the surrounding of boring a hole, and reduce because this density increases the hardness producing.Therefore,, in the time that such nonwoven web is administered to user's skin, it is very soft that user will feel.
In addition, because nonwoven web can be made with the voidage of low-density and increase, the liquid that therefore this nonwoven web can be discharged from user's health be transported to absorber fast.
And, even if using a small amount of fiber in the situation that, nonwoven web also can be made into have with without the identical thickness of perforation nonwoven web.That is to say, although use the low material of basic weight, nonwoven web also can be made with the thickness identical with non-porous non-woven fibre web, thereby causes the reduction of production cost.
In the time that the size of boring a hole is enough large, top flat can partly be recessed in these perforation, thereby reduces the contact area between top flat and user's skin.Meanwhile, the distance between top flat and absorber diminishes by means of perforation.So, absorb physical efficiency and absorb the moisture remaining in top flat by capillarity.Therefore, the reducing and remain in the minimizing of the moisture in top flat of contact area between top flat and user's skin, making to keep does not have moisture in the top flat of absorbent commodity.
If perforation is very high with the ratio of nonwoven web, the intensity of the nonwoven web of perforation will die down so, and easily deform in perforation step.For this reason, the nonwoven web of perforation can be provided with the nonwoven web without perforation of top side or the bottom side of the nonwoven web that is laminated to this perforation, thereby in not reducing the intensity of nonwoven web, keeps perforation and nonwoven web at high proportion.
