A three dimensional tape that may be used as a top sheet and a backsheet for a sanitary product, particularly a baby diaper or a sanitary pad. The three dimensional tape allows manufacturing of comparatively thinner, fluffless sanitary products with an improved comfort for the user. Manufacturing of the tape may be accomplished in-line, thereby dispensing with all of the logistics burden from outsourced products, and all of the environmental impact the logistics come with.

A disposable wearable article includes an elastic film stretchable structure in which an elastic film is laminated between a first sheet layer and a second sheet layer. The first sheet layer and the second sheet layer are bonded to each other through holes passing through the elastic film with many bonded portions arranged at intervals. A region having the elastic film stretchable structure includes a stretchable region that elastically stretches and contracts together with the elastic film. The stretchable region includes a plurality of elastic films disposed so as to have an overlapping portion. The number of laminated layers of the elastic film in a region located in an intermediate portion of the stretchable region in an orthogonal direction (XD) orthogonal to a stretchable direction (ED) is different from that in each of second regions adjacent to both sides of the first region.

An elastic sheet stretchable structure in which a first sheet layer and a second sheet layer are bonded through joint holes penetrating an elastic film at a plurality of sheet joined portions arranged at intervals is included. Joined portion groups in the stretchable region are in a relationship of intersecting a stretchable direction line at respective positions in an orthogonal direction or in a relationship of not intersecting the stretchable direction line at a separation width of 0.5 mm or less in the orthogonal direction of the stretchable direction line. The joined portion groups are in a relationship of not intersecting an oblique line at a predetermined separation width in the orthogonal direction in an oblique line group of oblique lines q in the orthogonal direction intersecting the stretchable direction line within an angle range γ of 45 degrees or less.

A method for producing an elastic laminate with at least a first top layer and an elastic film, wherein the first top layer is fed along a production direction to a first stretching device, is subsequently stretched transverse to the production direction by means of the first stretching device and is puckered, and is either connected to an extrusion web provided for forming the elastic film such that the top layer is connected to the extrusion web only by portions facing the melt web or is connected to a pre-produced elastic film in that the elastic film is at least incipiently melted on its side facing the first top layer, the first top layer is pressed against the at least incipiently melted side of the elastic film only by portions, and is therefore at least partially embedded in a polymer matrix of the elastic film.

The present invention relates to a hot melt adhesive composition having an enthalpy of crystallization below 5 J/g and comprising: a) at least 60% by weight of a composition a) comprising: —at least one copolymer A having a needle penetration higher than 15 dmm; —at least (co)polymer B having a needle penetration lower than 15 dmm; b) from 0% to 30% by weight of at least one tackifying resin.

A one-ply absorbent article comprising a nonwoven first layer; a non-woven third layer; a nonwoven second layer between the first layer and the third layer; and wherein the one-ply absorbent article has a first absorbency measure at a first delamination state and a second absorbency measure at a second delamination state, wherein the first absorbency measure is less than the second absorbency measure and the first delamination state is less than the second delamination state.

Textile backsheets including a nonwoven fabric and film, such as a vapor-permeable and liquid impermeable (VPLI) film or a non-permeable film, are provided, wherein the nonwoven fabric is directly or indirectly bonded to the film. Methods of making such textile backsheets and absorbent articles including the textile backsheets are also provided.

A thermoplastic elastomer compound includes a polyolefin elastomer blend of at least two different polyolefin elastomers, styrene-ethylene/butylene-styrene block copolymer, and plasticizer. The compound has a Melt Flow Rate (230° C., 2.16 kg) of no less than about 5 g/10 min and a Melt Flow Rate (190° C., 2.16 kg) of no less than about 1 g/10 min. Elastomeric films formed from the compound can be used in place of elastomeric films based on styrene-isoprene-styrene (SIS) block copolymers to make components of disposable hygiene articles.

A laminated assembly extends in a longitudinal direction and a lateral direction orthogonal to the longitudinal direction, the assembly including a non-woven sheet and an elastic film that are laminated together, the non-woven sheet including at least one activated zone extending over the length of the non-woven sheet measured in the longitudinal direction and over a width that is strictly less than the width of the non-woven sheet measured in the lateral direction, the degree of activation of the activated zone of the non-woven sheet in the lateral direction being different from the degree of activation of the elastic film in the lateral direction, the degree of activation of the activated zone of the non-woven sheet in the lateral direction lying in the range 20% to 200%.

A protective pad or garment portion, garments, and individual layers, being a moisture wicking layer, a core moisture absorbing layer and a moisture impermeable layer, and combinations thereof are disclosed.
