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 methods and apparatuses may be configured with a plurality of elastic strands wound onto a beam, wherein one or more elastic strands comprises a spin finish. During assembly of an elastomeric laminate, the beam is rotated to unwind the elastic strands from the beam. A portion of the spin finish may be removed from the advancing elastic strand with a spin finish removal apparatus. The spin finish removal apparatus may be configured to apply detergent to an advancing elastic strand and may also wipe and/or dry the advancing elastic strand. The treated stretched elastic strand may then be connected between a first substrate and a second substrate. In some configurations, adhesive may be applied to the treated the elastic strand, the first substrate, and/or the second substrate.
ABSORBENT ARTICLE AND FASTENING LAMINATE
Absorbent article including a chassis and fastening tab. The fastening tab includes a carrier, a first fastener having first male fastening elements, and a second fastener. The second fastener includes a backing with first and second opposing surfaces, with second male fastening elements on the first surface. A first portion of the second surface of the backing is connected to the carrier, and a second portion of the second surface of the backing is attached to the topsheet side of the chassis. The carrier is attached to the backsheet side of the chassis. Some fastening laminates, before attachment to the article, have the second portion of the second fastener folded over to face the first portion of the second fastener. Other laminates have the second fastener positioned with its first surface toward the carrier and attached to the carrier with a film.
PERFORATED STRETCH LAMINATE
A stretch laminate and a method for reducing and/or preventing tearing in a stretch laminate, when the stretch laminate is stretched in a stretching direction, is disclosed. The stretch laminate has a perforation pattern. The perforation pattern has at least two columns. A first column has a plurality of pairs of perforations stacked one pair above the other pair. The perforations in each pair sloping in a first direction, and a first space separating one pair from the other pair. A second column has a plurality of pairs of perforations stacked one pair above the other pair. The perforations in each pair sloping in a second direction, and a second space separating one pair from the other pair. The first direction and the second direction may be different. A third space between the columns is no greater than the first or second space between perforation in the pair.
Fasteners
The invention relates to fasteners comprising a flexible planar backing provided with a fastening element on its upper side and/or on its lower side, wherein the fastener consists of at least one generally Y-shaped one-piece section defined by two opposing arms, which are separated from each other by a recess, and by a third arm joined to the two opposing arms and extending away from said recess, wherein the shape and size of said third arm correspond to the shape and size of said recess.
Fastening member and fastening segment
Provided are a fastening member and a fastening piece for which an unpleasant texture and an incongruous appearance are significantly reduced, and that bring about an integrated feeling with the main body of a disposable article for wearing. A fastening segment includes a hook fastener and a base sheet. A hook height H1 of a hook is set to 45 μm to 150 μm, and a hook sheet thickness T2 is set to 45 μm to 75 μm. When in an L*a*b* color coordinate system, a color difference of L* is ΔL*, a color difference of a* is Δa*, and a color difference of b* is Δb*, a color difference ΔE between the hook fastener and the base sheet calculated using the ΔL*, the Δa* and the Δb*, is less than 5.5.
WEARABLE ARTICLE HAVING ELASTIC BELT
Disclosed is a wearable article 20 comprising a main body 38 and a ring-like elastic belt 40 comprising a front belt and a back belt each formed by an inner sheet, an outer sheet, and a plurality of elastic bodies sandwiched therebetween and running in the transverse direction substantially parallel to each other, and at least a portion of the elasticity of at least some of the elastic bodies are removed of its elasticity, the transverse width of the elastic body having the longest length removed of its elasticity defined as a maximum elastic cut window; wherein the length of the article along the longitudinal axis is from 300 mm to 440 mm; and the maximum elastic cut window is less than 100 mm.
ABSORBENT ARTICLE WITH POCKET PROVIDING ENHANCED CONTROL
An absorbent article (10) can include a pocket (64) disposed in the front waist region 12. The pocket (64) can include a first side edge (70), a second side edge (72), an upper lateral edge (74), and a lower lateral edge (76). The pocket (64) can be closed with respect to the absorbent assembly (44) at least at the first side edge (70) and the second side edge (72) and can be open with respect to the absorbent assembly (44) at least at the lower lateral edge (76). In one embodiment, at least a portion of the upper lateral edge (74) can be closer to the front waist edge (22) of the absorbent article (10) than is the first end edge (40) of the absorbent body (34).
CONFIGURABLE ABSORBENT ARTICLES
Configurable absorbent articles are provided. The absorbent articles may comprise a topsheet, a backsheet, and an absorbent core positioned at least partially intermediate the topsheet and the backsheet. The absorbent articles may comprise a first waist region, a second waist region, a crotch region extending intermediate the first waist region and the second waist region, and an outer cover material joined to the backsheet and forming a portion of a garment-facing surface of the absorbent article. The absorbent articles may comprise a pair of leg cuffs and a fully removable fastening member. The fastening member may comprise a first fastener on a first surface of the fastening member and positioned proximate to a first end and a second fastener on the first surface and positioned proximate to a second end. The absorbent articles may also comprise a wetness guard.
TAPED ABSORBENT ARTICLES WITH FRONT AND CROTCH CHANNELS
A taped absorbent article 20 comprising a crotch channel 26 having a crotch channel bond strength, and a front channel 56 having no bond or a front channel bond strength which is weaker than the crotch channel bond strength. The front channel is at least partially superposed with the landing zone 44 on which the back ear tapes 42 can be releasably fastened. During use, the front channel can delaminate to relieve stress on the landing zone and avoid accidental detachment of the tapes 42.
Refastenable absorbent article
An absorbent article is provided that comprises a front waist region, a back waist region, a crotch region disposed between the front waist region and the back waist region, a front waist end edge, a back waist end edge, a longitudinal axis extending from a mid-point of the front waist end edge to a mid-point of the back waist end edge, a first longitudinally extending side edge, a second longitudinally extending side edge, an exterior surface, an interior surface, a topsheet, a backsheet, and an absorbent core disposed between the backsheet and the topsheet. A portion of the front waist region and a portion of the back waist region are joined in a surface to surface relationship to form a pant comprising a first permanent side edge seam and a laterally opposed second permanent side edge seam. The first and second permanent side edge seams define an initial waist opening circumference and a pair of leg openings. The absorbent article comprises a first fastening component comprising a first fastening surface and a first attachment surface. The absorbent article comprises a second fastening component comprising a second fastening surface. The initial waist opening circumference formed by the first and second permanent side edge seams is configured to be opened. The first fastening surface and the second fastening surface are configured to be refastenably engaged and separated with each other.
