Shaped sheet manufacturing method
In a shaped sheet manufacturing method, it is possible to reliably shape a first sheet even if the tension of the first sheet is reduced at the time of manufacturing the shaped sheet. In a first step, a first sheet is conveyed along an outer peripheral surface of a first roll having a plurality of recessed parts. In a second step, a second sheet is overlapped with the first sheet and conveyed together with the first sheet so that the first and second sheets are held between the recessed parts of the first roll and projection parts of a second roll. In a third step, the first and second sheets having passed between the first roll and the second roll are bonded to each other. In the second step, the tension of the first sheet is made smaller than the tension of the second sheet.
Method for manufacturing absorbent body
A absorbent member manufacturing method of the invention is a method for manufacturing an absorbent member (100) including synthetic fibers (10b). The method involves: a transporting step of transporting a plurality of sheet fragments (10bh) including synthetic fibers (10b) to an accumulating depression (41) by using a duct 3; an accumulating step of accumulating, in the accumulating depression (41), the plurality of sheet fragments (10bh) transported in the transporting step, and forming an accumulation (100a′) which is a constituent member of the absorbent member (100); and a pressing step of pressing the accumulation (100a′) over its entirety in the thickness direction.
Methods and apparatuses for assembling elastic laminates with different bond densities for absorbent articles
The methods herein relate to assembling an elastic laminate with a first elastic material and a second elastic material bonded between first and second substrates. During assembly, an elastic laminate may be formed by positioning the first and second substrates in contact with stretched central regions of the first and second elastic materials. The elastic laminates may include two or more bonding regions that may be defined by the various layers or components of the elastic laminate that are laminated or stacked relative to each other. In some configurations, a first plurality of ultrasonic bonds are applied to the elastic laminate to define a first bond density in the first bonding region, and a second plurality of ultrasonic bonds are applied to the elastic laminate to define a second bond density in the second bonding region, wherein the second bond density is not equal to the first bond density.
Structurally-colored articles and methods for making and using structurally-colored articles
One or more aspects of the present disclosure are directed to bladders that incorporate a multi-layer optical film that impart a structural color to the bladder. The present disclosure is also directed to articles including the bladders having a multi-layer optical film, and methods for making articles and bladders having a multi-layer optical film.
METHOD AND APPARATUS FOR MAKING PATTERNED APERTURED SUBSTRATES
The present disclosure relates to apparatuses and methods for making patterned apertured substrates that may be used as components of absorbent articles. During the manufacturing processes, a precursor substrate advances in a machine direction between a pattern roll and an anvil roll. The pattern roll rotates about an axis of rotation and includes a plurality of pattern surfaces, wherein the substrate is compressed between the anvil roll and the pattern surfaces of the pattern roll to form discrete bond regions in the substrate. The pattern surfaces on the pattern roll are formed on continuous threads extending circumferentially around the axis of rotation along helical paths parallel with each other. As such, the pattern surfaces press the substrate against the outer circumferential surface of the anvil roll in the different axial locations along the cross direction as the pattern roll rotates when forming the discrete bond regions.
APPARATUS AND PROCESS FOR DEFORMING A WEB
The present invention relates to an apparatus for deforming a web to created deformed nonwoven which comprises a pair of counter-rotating rolls that form a nip therebetween, the pair of rolls comprising: a first roll comprising a surface, a plurality of protrusions extending radially outwardly from the surface of the first roll, and a plurality of concaves formed inwardly from the surface of the first roll; and a second roll comprising a surface; and a process for producing a deformed web comprising the steps of (a) forming a fibrous web; (b) subjecting the fibrous web to bonding treatment to bond at least part of fibers constituting the fibrous web to obtain a precursor nonwoven; and (c) subjecting the precursor nonwoven to a deformation forming unit comprising an apparatus according to the present invention.
Nonwoven And Absorbent Articles Having The Same
The present invention relates to a three-dimensional nonwoven comprising a first side, a second side, a protruded first area comprising an upper portion formed in the first side and a lower portion formed in the second side, and a second area comprising a plurality of deformations, wherein the upper portion has a shape memory index higher than a shape memory index of the lower portion, an absorbent article comprising the three-dimensional nonwoven, and a process for producing the three-dimensional nonwoven.
METHOD AND APPARATUS FOR ASSEMBLING ABSORBENT ARTICLES
The present disclosure relates to methods and apparatuses for assembling elastic laminates that may be used to make absorbent article components. Particular aspects of the present disclosure include providing a first substrate and a second substrate, the first substrate and the second substrate, each having a width in a cross direction; providing an elastic material; elongating the activated elastic material using a spreader mechanism; and ultrasonically bonding the first substrate together with the second substrate with the elongated activated elastic material positioned between the first substrate and the second substrate using an anvil and an ultrasonic device.
