LAMINATE(S) COMPRISING BEAMED ELASTICS AND ABSORBENT ARTICLE(S) COMPRISING SAID LAMINATE(S)
The present disclosure relates to one or a combination of an absorbent article's chassis, inner leg cuffs, outer leg cuffs, ear panels, side panels, waistbands, and belts that may comprise one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or very fine (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand method below) under the elastics, while providing adequate modulus of (between about 2 gf/mm and 15 gf/mm) to make the article easy to apply and to comfortably maintain the article in place on the wearer, even with a loaded core (holding at least 50 mls of liquid), to provide for the advantages described above.
METHOD FOR PRODUCING PRINTED NONWOVEN-FILM LAMINATES
The invention relates to a method for producing a printed nonwoven film laminate from a starting film web of a thermoplastic polymer material and a starting nonwoven web, wherein the melting point of the starting nonwoven web is above the crystallite melting point of at least one component of the polymer material of the starting film web. The method includes at least partially coating the starting film web with a printing ink and with an adhesion promoter; heating the coated film web together with the starting nonwoven web to a temperature which is above the crystallite melting point of the at least one component of the polymer material of the starting film web and of the adhesion promoter and below the crystallite melting point of the starting nonwoven web, to obtain a laminate; and cooling the laminate obtained through a cooled roller nip. Furthermore, the invention relates to printed nonwoven film laminates produced by the method and their use.
DISPOSABLE ABSORBENT ARTICLES HAVING CUFFS OF IMPROVED STRETCH LAMINATE STRUCTURE
An absorbent article having longitudinal cuffs of improved structure is disclosed. The improved cuffs may be elasticized by a plurality of elastic strands that are substantially greater in number, closer in spacing, lower in pre-strain, and lower in decitex, or any combination of these, as compared with those in conventional articles. This combination of features results in ruffles or gathers of cuff material joined to the elastic strands that are substantially greater in machine-direction frequency and substantially lesser in z-direction amplitude, than those in conventional articles. As a result, the cuff structure lies more closely and evenly against the wearer's skin, has an improved, more cloth-like appearance, provides improved gasketing, and provides improved wearer comfort, as compared with cuff structures in conventional articles. A method for manufacturing articles with such cuff structures, utilizing a warp beam as a supply mechanism, is also disclosed.
LENGTH-TO-WAIST SILHOUETTE(S) OF ABSORBENT ARTICLE(S) COMPRISING BEAMED ELASTICS
The present disclosure relates to absorbent articles comprising belts comprising one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or low decitex (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand Test in the Method below) under the elastics, while providing adequate Section-Modulus of (between about 2 gf/mm and 15 gf/mm), resulting in a Product Length-to-Waist Silhouette that is within from about −0.3 to about 0.3 of the Target Body Length-to-Waist Silhouette to make the article conform better to the body of the wearer at a lower Pressure-Under-Strand, even with a loaded core (holding at least 50 mls of liquid), to provide for the advantages described above.
Sandwich Panel And A Manufacturing Method Thereof
The present invention relates to a sandwich panel and a method of manufacturing the same. The sandwich panel according to the present invention has high density and improved physical properties such as flexural strength, flexural modulus, bending strength and lightening weighting ratio and is suitable for use in various consumer products or industrial materials.
Disposable medical drape
Self-clamping drape systems, apparatuses, kits and methods are shown and described. End drape systems, apparatuses, kits and methods are shown and described. A disposable medical drape may include a drape and a self-clamping system. A disposable medical drape system may include a drape, a self-clamping system and one or more end drapes. A self-clamping drape may have attached clamps and/or be secured by way of self-clamping clamps. The medical drape system may form a barrier beneath a medical operating room table.
Nonwoven webs with hydrophobic and hydrophilic layers
A nonwoven web for use in an absorbent article is described. The nonwoven web has first and second nonwoven layers. The first nonwoven layer has a first plurality of fibers, an additive disposed, at least in part, on a portion of the first plurality of fibers, a first side and an opposing second side, wherein second side has a plurality of discontinuities. The second nonwoven layer has a second plurality of fibers, a first surface and an opposing second surface, and a plurality of tufts extending through at least a portion of the discontinuities in the first nonwoven layer, wherein the second nonwoven layer is attached to the first nonwoven layer such that at least a portion of the second plurality of fibers are in liquid communication with the first nonwoven layer, wherein the first nonwoven layer is hydrophobic and the second nonwoven layer is hydrophilic.
METHODS AND APPARATUSES FOR MAKING ELASTOMERIC LAMINATES WITH ELASTIC STRANDS UNWOUND FROM BEAMS
The present disclosure relates to methods for assembling elastomeric laminates, wherein elastic material may be stretched and joined with either or both first and second substrates. A first beam is rotated to unwind a first plurality of elastic strands from the first beam in the machine direction. The first plurality of elastic strands are positioned between the first substrate and the second substrate to form the elastomeric laminate. Before the first plurality of elastic strands are completely unwound from the first beam, a second beam is rotated to unwind the second plurality of elastic strands from the second beam. Subsequently, the advancement of the first plurality of elastic strands from the first beam is discontinued. Thus, the elastomeric laminate assembly process may continue uninterrupted while switching from an initially utilized elastic material drawn from the first beam to a subsequently utilized elastic material drawn from the second beam.
ABSORBENT ARTICLE(S) CHASSIS COMPRISING BEAMED ELASTICS
The present disclosure relates to absorbent article's chassis that may comprise one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or low decitex (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand Test in the Method below) under the elastics. The elastics in the chassis may be oriented parallel or transverse to the longitudinal axis.
Methods and Apparatuses for Making Elastomeric Laminates with Elastic Strands Unwound from Spools on Surface Unwinders
The present disclosure relates to methods for assembling elastomeric laminates, wherein elastic material may be stretched and joined with either or both first and second substrates. First spools are rotated to unwind first elastic strands from a first unwinder in a machine direction. The first elastic strands are positioned between the first substrate and the second substrate to form an elastomeric laminate. Before the first elastic strands are completely unwound from the rotating first spools, second spools are rotated to unwind second elastic strands from a second unwinder. Subsequently, the advancement of the first elastic strands from the first unwinder is discontinued. Thus, the elastomeric laminate assembly process may continue uninterrupted while switching from an initially utilized elastic material drawn from the first spools to a subsequently utilized elastic material drawn from the second spools.
