Methods and apparatuses for making elastomeric laminates with elastic strands provided with a spin finish
The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. The elastomeric laminates may include a first substrate, a second substrate, and an elastic material located between the first and second substrates. During assembly of an elastomeric laminate, a beam is rotated to unwind the elastic strands from the beam, wherein the strands may include a spin finish. First bonds are applied to bond discrete lengths of the stretched elastic strands with and between the first substrate and the second substrate, wherein the discrete first bonds are arranged intermittently along the machine direction. In addition, second bonds are applied between consecutive first bonds to bond the first and second substrates directly to each other, wherein the second bonds extend in the machine direction and may be separated from each other in a cross direction by at least one elastic strand.
Disposable diaper
[Problem] To provide a disposable diaper which is comfortable to wear. [Solution] This disposable diaper comprises a top sheet (1), a back sheet (2), an absorber (3) and a stretchable sheet (4). The stretchable sheet (4) is composed by having a base material sheet (41) sandwich multiple elastic stretchable members (42) disposed therein in an extended state, said multiple elastic stretchable members (42) being disposed along the width direction of the disposable diaper and spaced apart at intervals in the longitudinal direction. When viewed in the width direction, the stretchable sheet (4) has an overlapping portion (43) which includes a region that overlaps with a part of the absorber (3). In the overlapping portion (43), the multiple elastic stretchable members (42) are disposed continuously along the width direction. The multiple elastic stretchable members (42) are not joined to the sides of the base material sheet (41) at the central region (43a) of the overlapping portion (43), said central region (43) being where part of the absorber (3) is overlapped, and are joined to the sides of the base material sheet (41) at the side regions (43b) of the overlapping portion (43) which are positioned to the outside of the central region (43a) in the width direction.
Absorbent articles with hook and loop fastening system
A disposable absorbent article having a fastening system with male and female components is disclosed. The female component may include a fibrous material having an overall thickness and an overall fiber cross-sectional dimension. The male component may include a plurality of hooks configured to engage the female component, the hooks having features with dimensions relating to the overall thickness and/or the overall fiber cross-sectional dimension of the fibrous material.
Diaper support garment for four-legged animal
A diaper support garment for a four-legged animal comprises an article of animal clothing shaped to substantially cover fore and midsection body areas of a four-legged animal without covering or interfering with the waste product discharge areas of the animal; a closable utility envelope for defining at least one storage compartment which is removably secured to the article of animal clothing for helping to prevent displacement and slippage of a disposable diaper from a hindquarter area of the four-legged animal when the disposable diaper is worn in combination with the primary protective garment; the closable utility pocket being provided with a closure flap to seal the at least one storage compartment to conceal and store for deployment when needed at least one tethered diaper coupler for securely gripping and helping to maintain the disposable diaper in an intended animal protective position for capturing and collecting animal waste products discharged from the four-legged animal.
Absorbent article with extensible ears
An absorbent article has a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and backsheet; first and second opposing longitudinal side edges, a front waist region and a back waist region; and a first and second back ear extending outwardly from the first and longitudinal side edges in the back waist region, respectively. The first and second back ears have an engineering strain greater than about 8% at about or below 2N of force when measured according to the Back Ear Extension Test, and a roughness Ra lower than about 300 ?m when measured according to the Roughness Test.
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.
ABSORBENT ARTICLE WITH EXTENSIBLE EARS
An absorbent article has a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and backsheet; first and second opposing longitudinal side edges, a front waist region and a back waist region; and a first and second back ear extending outwardly from the first and longitudinal side edges in the back waist region, respectively. The first and second back ears have an engineering strain greater than about 8% at about or below 2N of force when measured according to the Back Ear Extension Test, and a roughness Ra lower than about 300 ?m when measured according to the Roughness Test.
Beamed elastic laminate properties
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 and/or low Average-Dtex and/or low Average-Pre-Strain elastics to deliver low Pressure Under Strand, while providing adequate Section-Modulus to make the article easy to apply and to comfortably maintain the article in place on the wearer, even with a loaded core, to provide for the advantages described above. Further, the elastomeric laminates of the present disclosure outperform existing laminates currently used for disposable absorbent articles as it relates to one or more key parameters (including Percent Contact Area, 2-98% Height Value, Pressure-Under-Strand, Air Permeability, Water Vapor Transmission Rate, Caliper, Caliper Retention Value, Cantilever Bending, Open Area, Section-Modulus, Rugosity Wavelength, Rugosity Frequency, Graphic Distortion Ratio).
