An elastically stretchable disposable wearing article 1 has a front waist region 6, a rear waist region 7 and a crotch region 8. This wearing article 1 is formed with a first elastic zone 21, a second elastic zone 22 and third elastic zones 23 respectively exhibiting stretch stress adjusted to be decreased in this order. An elastically stretchable web is continuously fed in a machine direction, formed with pairs of slits in desired patterns so that two slits constituting each of the pairs may be symmetrically laid about a transversely middle zone of the web and then folded in a cross direction orthogonal to the machine direction so that the web may be alternately overlapped on itself about the transversely middle zone to form the wearing article 1.

An absorbent article has an anterior region, a posterior region and a central region interconnecting the anterior and posterior regions and extending longitudinally therebetween. An elastic component extends generally continuously along a path from the anterior region of the article through the central region to the posterior region thereof. The elastic component has an elastic tension which is substantially non-uniform along the path defined by the elastic component. In one method for making such an absorbent article, an elastic component is initially secured to the article along the path and defines a width thereof. At least a portion of the elastic component is then removed from the article to narrow the width of the path defined by the elastic component along at least a segment of the path to thereby provide an elastic tension gradient along the length of the path.

An elastomeric adhesive composition including a high softening point tackifier resin in combination with a base polymer can be used to create laminates having effective adhesion and elastic properties. The compositions may be in the form of a sheet of film or a plurality of strands. Facing layers, such as nonwoven webs and/or films, can be self-adhered to one or both surfaces of the elastomeric adhesive composition to form a laminate. A method of making such compositions and laminates can be carried out using the conventional hot melt equipment.

A strand coating system and method including drawing (710) a strand having major and minor dimensions past an adhesive dispensing nozzle, orienting (720) at least a portion of the strand so that the major dimension of the strand is substantially parallel to a direction in which adhesive is dispensed from the adhesive dispensing nozzle as the portion of the strand is drawn past the adhesive dispensing nozzle, and applying (730) adhesive to the strand as the strand is drawn past the adhesive dispensing nozzle.

The absorbent article has an outer sheet that provides an outer surface of the absorbent article, an inner sheet disposed on the inner side of the outer sheet, and elastic members for making below-waist gathers disposed between the two sheets. A patterned sheet is disposed between the outer and inner sheets such that the pattern of the patterned sheet may be seen through the outer sheet from the outside of the diaper. The elastic members for below-waist gathers each have a portion contributory to elastic extensibility and contractibility in the regions outside the lateral sides of the patterned sheet and a portion substantially non-contributory to elastic extensibility and contractibility in the region inside the lateral sides of the patterned sheet. The latter portion of the elastic member is disposed between the patterned sheet and the inner sheet and preferably is kept out of sight from the outside.

A method of manufacturing an elasticized composite material including a multiplicity of elastic strips for use in garments, particularly in disposable absorbent articles is disclosed. The method includes the steps of folding the first substrate around the mandrel to form a tube while moving the tube longitudinally at a first velocity, and simultaneously winding at least one elastic strip around an outer surface of the tube at a second velocity to form a helical path. The elastic strip can be joined to the outer surface of the tube along the helical path to form a first composite tube. The method further includes the step of folding a second substrate around the first composite tube to cover the elastic strip and to form a second composite tube, which then can be slit longitudinally to form a planar composite material. Finally, the planar composite material can be activated to form the elasticized composite material.

A method for fabricating a refastenable absorbent garment includes moving a continuous body panel web in a machine direction and successively fixedly securing a plurality of discrete fastener pieces, spaced along the machine direction, to the body panel web. Each of the fastener pieces comprises a first and second end also spaced along the machine direction. The method further includes successively cutting said body panel web and each of the fastener pieces along a cross direction between the first and second ends of each of the fastener pieces and thereby forming a plurality of discrete body panels each comprising opposite side edges and a plurality of pairs of fastener members fixedly secured to one of the plurality of body panels and a next successive body panel.
摘要:
A process for providing feedforward control to control the feed rate of an elastic material. The process involves measuring the distance between registration marks on the elastic material prior to cut-off. These measurements are compared to a target cut length. The feed rate of a feed roll is adjusted, based on the target cut length and the distance between the registration marks, to maintain the cut length of the elastic material at the target cut length.
摘要:
This invention pertains to a three-dimensional disposable garment (25) and subassemblies (10) of the garment (25). The garment (25) is designed to hold a primary absorbent sanitary pad. The garment (25) may have elasticized leg and waist openings (38, 44, 46,) and be stretchable about the hip and stomach regions of a user. The garment (25) provides backup protection to control egress of fluids that leak or seep around or through the primary sanitary pad. The garment (25) includes a secondary absorbent positioned in the crotch area (24) and extending into the body of the disposable garment (25), front and back, and preferably over the leg elastics (46, 48) to trap, inside the garment, leakage from the primary absorbent, and to prevent strike through onto e.g. outer clothing and bed linen. The garment blank and disposable garment, respectively, comprise first and second layers collectively extending from the front end through the crotch portion to the back end. The first and second layers collectively define an unsecured space displaced from the front end and displaced from the back end, the unsecured space being free from securement of the first and second layers to each other, the second section of the first elastic being disposed in the unsecured space.
