摘要:
A topsheet for body fluids absorbent article is made of thermoplastic synthetic fibers mechanically entangled so as to extend substantially in a desired one direction and formed with liquid-permeable openings. The openings comprise a first group of openings each having a substantially oval shape defined by its major axis extending substantially in parallel to the direction in which the fibers extend and its minor axis extending orthogonally to the major axis and a second group of openings each having a substantially oval shape defined by its minor axis extending substantially in parallel to the direction in which the fibers 11 extend and its major axis extending orthogonally to the minor axis.

A topsheet for body exudates absorbent article includes a hydrophilic nonwoven fibrous sheet and a plurality of thermoplastic synthetic resin filaments extending in one direction parallel to one another and continuously bonded to an upper surface of the nonwoven fibrous sheet so that a composite sheet of these sheet and filaments have crests and troughs alternately repeating longitudinally of the filaments and respectively extend transversely of the filaments. An apparatus and a method for manufcturing the topsheet are also disclosed, wherein a pair of mutually engageable embossing rolls are used for forming the crests and the troughs onto the coposite sheet.

A method for making an apertured nonwoven fabric includes the steps of: obtaining wet sheet from slurry containing 0.5˜20% by weight of fibrous component in water, which comprises, in turn, thermoplastic synthetic fibers having a length of 7˜30 mm and a fineness of 0.1˜0.8 d, and subjecting the wet sheet to a processing for fiber entangling by high velocity water jet streams and to a processing for aperture forming by aperture forming elements having predetermined configurations adapted to be followed by individual fibers.

摘要:
A liquid-permeable topsheet used in a disposable body fluids absorbent garment has planar portions substantially extending in a horizontal plane, a plurality of ribs rising from the planar portions and extending parallel one to another, each presenting a cross-section in an inverted v-shape, and liquid-passages extending downward from the planar portions and thereby eliminate any appreciation that eruption and/or stuffiness might be caused by contact of the topsheet with the skin of a wearer.
摘要:
A body fluids absorbent article has a liquid-permeable topsheet formed by a nonwoven fabric of thermoplastic synthetic fibers. The topsheet is formed with a plurality of openings each having a diameter of 0.5.about.3 mm. These openings queue up so as to form plural columns of openings extending in parallel one to another. One half or more of a total number of the openings are reinforced by strands of thermoplastic synthetic resin each having a diameter of 0.1.about.0.5 mm and extending circumferentially of the respective openings.
摘要:
Short fibers of thermoplastic synthetic resin are fusion bonded to one another to form a nonwoven fabric. The nonwoven fabric is formed on its upper surface with crests and troughs extending in parallel to one another. The crests include first crests having a uniform height dimension from a lower surface of the nonwoven fabric and second crests having a uniform height dimension from a lower surface of the nonwoven fabric which is smaller than the height dimension of the first crests. Density of the nonwoven fabric gradually increases in the order of the first crests, the second crests and the troughs. The first crests are formed so that the density of the first crests remains lower than the density of the second crests even when the first crests are compressed toward the lower surface until the first crests becomes flush with the level of the second crests.
摘要:
An elastically stretchable composite sheet includes an elastically stretchable first web and an inelastically stretchable second web of thermoplastic synthetic resin fiber which is intermittently bonded to the first web in a y-direction. Component fiber of the second web has its cress-section cut in a direction orthogonal to the y-direction defined by a width w and a height h dimensioned to be at a ratio h/w less than 0.5. The composite sheet having such a structure improve its flexibility.
