ELASTIC SHEET FOR ABSORBENT ARTICLE AND ABSORBENT ARTICLE
An elastic sheet for an absorbent article includes a first fibrous layer disposed on a first surface of the elastic sheet, a second fibrous layer disposed on a second surface of the elastic sheet opposite to the first surface, and contractible elastic members secured between the first fibrous layer and the second fibrous layer. The first fibrous layer and the second fibrous layer each include continuous fibers of thermoplastic and gathers formed between adjacent ones of the elastic members. The gathers are disposed in an intersecting direction intersecting with a direction in which the elastic members extend. An average flexural rigidity value of the first fibrous layer and the second fibrous layer in accordance with a KES method is 0.003510.sup.4 to 0.02210.sup.4 (N.Math.m.sup.2/m). A thickness under a compression load to the gathers in accordance with the KES method is 0.22 to 1.5 mm.
MASK SHEET, METHOD FOR MANUFACTURING SAME, AND MASK COMPRISING SAME
A sheet (10) for a mask has a first fiber layer (11) and a second fiber layer (12). The second fiber layer (12) has a higher trapping ratio for particles having a particle diameter exceeding 1 m and/or a smaller average fiber diameter than the first fiber layer (11). The basis weight of the second fiber layer (12) is from 1 to 20 g/m.sup.2. In a natural state, the second fiber layer (12) has a plurality of projections (13) projecting toward a surface of the second fiber layer (12) that is opposite to a surface of the second fiber layer (12) facing the first fiber layer (11) and depressions (14) that are each arranged between corresponding projections (13) of the plurality of projections (13). The depressions (14) have joined portions (15) where the second fiber layer (12) and the first fiber layer (11) are joined to each other.
SUBSTRATES HAVING REPEATING PATTERNS OF APERTURES FOR ABSORBENT ARTICLES
The present disclosure is directed to substrates or topsheets having repeating patterns of apertures for absorbent articles. Each of the repeat units comprises at least three apertures.
ADAPTABLE ABSORBENT ARTICLES
An absorbent article having a longitudinal axis and a transverse axis is provided. The article has a topsheet and backsheet, together forming a chassis that is symmetrical about the transverse axis. An absorbent core is disposed between the topsheet and the backsheet, with a perimeter of the chassis extending beyond the surface area of the core. The absorbent core is asymmetrical about the transverse axis. In one embodiment, less than 50% of the surface area of the absorbent article is mechanically compressed. In another embodiment, the absorbent article has an in-use flexibility of less than 170 mN, preferably less than 130 mN. In a further embodiment, the absorbent article has a stiffness measured in the core free area of less than 0.4 g*cm.
SANITARY MASK SHEET
A sanitary mask sheet, in which a WC value indicating a work volume up to a maximum pressure in a thickness direction is 0.3 Pa.Math.m or more, and a capture rate of particles having a particle diameter of more than 1 m is 85% or more.
Elastic sheet for absorbent article and absorbent article
An elastic sheet for an absorbent article includes a first fibrous layer disposed on a first surface of the elastic sheet, a second fibrous layer disposed on a second surface of the elastic sheet opposite to the first surface, and contractible elastic members secured between the first fibrous layer and the second fibrous layer. The first fibrous layer and the second fibrous layer each include continuous fibers of thermoplastic and gathers formed between adjacent ones of the elastic members. The gathers are disposed in an intersecting direction intersecting with a direction in which the elastic members extend. An average flexural rigidity value of the first fibrous layer and the second fibrous layer in accordance with a KES method is 0.003510.sup.4 to 0.02210.sup.4 (N.Math.m.sup.2/m). A thickness under a compression load to the gathers in accordance with the KES method is 0.22 to 1.5 mm.
DEVICE FOR PRODUCING A COMPOSITE NONWOVEN WEB
A device for producing a composite nonwoven web which includes a first layer and a second layer. The first layer has a spunbonded nonwoven and/or long fibers. The first layer has an upper face and a first width. The second layer has short fibers and a second width. The device includes at least one conveyor device which transports at least the first layer in a conveying direction, a headbox system which dispenses the short fibers onto the upper face of the first layer between two edges which extend transversely to the conveying direction, and a collecting device which is arranged so that some of the short fibers dispensed from the headbox system can be collected in a region of at least one of the two edges before the short fibers which are dispensed in the region come into contact with the upper face of the first layer.
SOUND-ABSORBING MATERIAL AND METHOD OF MAKING SUCH A SOUND-ABSORBING MATERIAL
Sound-absorbing material includes a monolithic main layer which is made of non-woven fiber fabric and has two opposite faces delimiting the thickness of the monolithic main layer. The monolithic main layer has a density gradient in the direction of its thickness. The monolithic main layer has a gradient in the fiber count in the direction of its thickness which decreases, passing from a first face to a second face of the monolithic main layer. The density gradient has an inverse trend with respect to the gradient in fiber count.
WEARABLE ARTICLE COMPRISING A LAMINATE
Wearable article comprising a laminate with excellent sweat management properties. The laminate comprises a first web and a second web. The second web is formed of a first fibrous layer and a second fibrous layer, which are integrally combined with each other. The second fibrous layer may be more hydrophilic than the first fibrous layer; and/or the second fibrous layer may have higher average surface area per volume than the first fibrous layer.
Multilayered nonwoven fabric containing submicron fibers, a method of manufacture, an apparatus, and articles made from multilayered nonwoven fabrics
This document presents a novel method of manufacturing multilayered nonwoven fabrics consisting of submicron fibers, hydroentangled, meltfibrillated, and/or spunlaid web layers. The composite multilayered webs contain one or more submicron fiber webs placed between inner and outer layers of hydroentangled, meltfibrillated, and/or spunlaid web, forming a fabric that may be utilized in the manufacture of articles which serve as barriers, wipes or sorbent materials, or may have other potential applications. The created novel composite multilayered fabric may have increased loft, softness and bending length, may not be solely dependent upon an electrostatic charge to repel small particles and microbes, and may be formed from a broad selection of natural, synthetic, and recycled polymers, including petroleum- and plant-based, allowing polymer selection based on article lifecycle.
