An absorbent article comprising an absorbent core comprising absorbent material. The absorbent core is sandwiched between a liquid-permeable upper core cover layer and a lower core cover layer. The absorbent core has one or more elongated areas arranged therein, each elongated area being an absorbent material free area having a length as measured along the elongated area and a width. The upper core cover layer and the lower core cover layer in each of the one or more elongated absorbent material free areas are attached to each other within at least 2 attachment zones and at most 12 attachment zones, the attachment zones being spaced-apart in the longitudinal direction (Y) within each of the one or more absorbent material free areas.

Aspects of the present disclosure relate to absorbent articles with front and back waist panels having different stretch characteristics. A first waist panel may be connected with a chassis and positioned in a first waist region, and a second waist panel may be connected with the chassis and positioned in a second waist region. In some configurations, the first waist panel may comprise a first structural feature that is not included in the second waist panel or may comprise a first structural feature is different from a second structural feature included in the second waist panel. As such, the first structural feature provides different stretch characteristics between the first waist panel and the second waist panel.

A hydro-degradable fluid absorbent product and its componentry, construction, and a method of manufacturing the same. The hydro-degradable fluid absorbent includes a top sheet formed of hydro-degradable layer, wherein the top sheet along with the edges is coated with hydrophobic coating that covers 0-80% of the said sheet and 100% of its edges, an absorbent core, optionally with super absorbent polymer, a bottom sheet including at least one water soluble film characterised by a tie layer which is coated on water-soluble film followed by moisture barrier coat. The method of manufacturing includes assembling a top sheet formed by a hydro-degradable layer, an absorbent core, optionally with super absorbent polymer, the bottom sheet including at least one water soluble film characterized by a tie layer, and bonding the top sheet, the bottom sheet with the absorbent core sandwiched in between by utilizing appropriate industrial bonding techniques.

A sanitary article comprises a main body comprising a top and bottom sides and an absorbent core therebetween surrounded and bounded by a core border formed in the top and bottom sides. The top side defines a body contacting surface within the core border. The bottom side defines an undergarment contacting surface within the core border. A main body contour extends beyond the core border and is surrounded and bounded by a sealed main body perimeter defining opposite main body longitudinal ends and opposite main body lateral sides. Each main body lateral side having front and rear portions thereof and a middle portion therebetween. A respective tear line is defined between the inner lateral part of each one of the pair of wings and the middle portion. When a sufficient tearing force is applied to the tear line thereby a wing is fully removed from the main body without physical integrity disturbance of the sealed perimeter at each of the middle portions.

An absorbent article comprising a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent core comprising an absorbent material between a top core wrap sheet and a back core wrap sheet, said absorbent core being positioned in between said topsheet and said backsheet, wherein the absorbent core is provided with at least one attachment zone between the top core wrap sheet and the back core wrap sheet, wherein a first binder is arranged in a first area between the top core wrap sheet and the back core wrap sheet at a distance from the at least one attachment zone, on one of the top core wrap sheet and the back core wrap sheet and a second binder is arranged in a second area between the top core wrap sheet and the back core wrap sheet, on the other of the top core wrap sheet and the back core wrap sheet.

Aspects of the present disclosure relate to absorbent articles with front and back waist panels having different stretch characteristics. A first waist panel may be connected with a chassis and positioned in a first waist region, and a second waist panel may be connected with the chassis and positioned in a second waist region. In some configurations, the first waist panel may comprise a first structural feature that is not included in the second waist panel or may comprise a first structural feature is different from a second structural feature included in the second waist panel. As such, the first structural feature provides different stretch characteristics between the first waist panel and the second waist panel.

A method is presented for providing a continuous web to an absorbent article manufacturing line. The method includes conveying a first roll of material through a splice box. The method also includes providing a second roll of the material extending into the splice box. The method also includes sensing upcoming expiration of the first roll of material. The method also includes using a first and second vacuum to hold a respective first portion of the first roll and a second portion of the second roll against first and second components of a thermal welding apparatus. The method also includes forming a thermal weld at the splice location between the first and second portions. The method also includes cutting the first roll of material upstream of the thermal weld. The method also includes conveying the second roll of material through the splice box without stoppage of the absorbent article manufacturing line.

An absorbent article including a non-woven substrate of one or more layers of meltblown fibers and a first layer of spunbond fibers and a second layer of spunbond fibers. The absorbent article further includes an absorbent core comprising at least one of fibers or a superabsorbent polymer. At least one of the non-woven substrate or the absorbent may be treated with an alcohol repellency (AR) treatment.

The absorbent article as disclosed herein has longitudinal side edges extending in a longitudinal direction and transverse front and rear end edges extending in a transverse direction. The absorbent article comprises a fluid permeable surface layer, a backsheet and an intermediate layer located between the fluid permeable surface layer and the backsheet. The surface layer has a wearer-facing portion facing the user during use. The surface layer is an air through bonded fibrous nonwoven surface layer having a basis weight of from 14 to 30 g/m2 and a density of from 20 to 90 kg/m3. The intermediate layer extends under from 70 to 100% of the wearer-facing portion of the surface layer. The intermediate layer and the surface layer have a respective elongation at 10 N/50 mm. The elongation of the intermediate layer is lower than the elongation of the surface layer.

A method for forming a wearable absorbent article may comprise forming, by a system, an absorbent chassis comprising an absorbent core, a first lateral end, a second lateral end, and a length in a longitudinal direction extending between the first lateral end and the second lateral end. The method may further comprise forming, by the system, a reusable belt, and attaching, by the system, the belt to the absorbent chassis via at least one temporary fastener component formed on at least one of the absorbent chassis or the belt, resulting in formation of a wearable absorbent article unit.
