This non-woven fabric comprises the following configuration. In this non-woven fabric for a liquid-permeable sheet of an absorbent article, said non-woven fabric comprising a thickness direction, a planar direction, a first face, and a second face: the non-woven fabric includes thermoplastic resin fibers, and cellulosic fibers, at least a portion whereof configures a plurality of fiber masses; the non-woven fabric further comprises a plurality of spaces which are adjacent to first regions of each of the plurality of fiber masses, said first regions facing the first face; and each of the plurality of fiber masses is not bonded to the thermoplastic resin fibers.
MULTI-COMPONENT TOPSHEETS HAVING THREE-DIMENSIONAL MATERIALS
The present disclosure is directed to multi-component topsheets having three-dimensional materials. The present disclosure is directed to absorbent articles having multi-component topsheets having three-dimensional materials. The three-dimensional materials may have apertures. The topsheets may have a first material, a second material, and a third material. The first and second materials may be the same and the third material may be different from the first and second materials. The first and second materials may have a lower basis weight than the third material.
ABSORBENT ARTICLE WITH HYBRID NONWOVEN WEB
An absorbent article comprises a topsheet, a backsheet, and an absorbent core positioned between the topsheet and the backsheet. The absorbent article comprises a nonwoven web. The nonwoven web having a first side and a second side. The nonwoven web comprises thermoplastic fibers and cellulosic fibers. At least a portion of the thermoplastic fibers are present on the first side and at least a portion of the cellulosic fibers are present on the second side. The nonwoven web has a pattern of discrete bond points, wherein the pattern of discrete bond points has a fiber free-length parameter, as defined by the Fiber Free-Length Test, with a value of less than 2.90 mm The second side of the nonwoven web forms part of an exterior surface of the absorbent article.
Topsheet comprising natural fibers with good mechanical strength
A topsheet for use with an absorbent article is provided and comprises a first layer and a second layer. The first layer may be a spunlace nonwoven and may comprise at least 15% by weight of natural fibers by total weight of the first layer. The first layer may comprise a plurality of protrusions and a plurality of apertures. The first layer and the second layer may be in contact with each other between the majority of the protrusions. The second layer may have a plurality of apertures at least partially aligned with the apertures of the first layer. The first layer may have a minimum CD strength of at least 3N/(5 cm), according to the Tensile Strength Test Method.

A nonwoven fabric for an outer sheet of an absorbent article has a liquid-impermeable sheet having moisture vapor permeability, the nonwoven fabric having a thickness direction and a planar direction, and a first surface and a second surface, the nonwoven fabric including thermoplastic resin fibers, and cellulosic fibers that are cellulosic fibers of which at least a portion form a plurality of fiber masses, the nonwoven fabric comprising a plurality of gaps that are adjacent to first regions of each of the plurality of fiber masses that are facing the first surface, wherein each of the plurality of fiber masses are not joined with the thermoplastic resin fibers.
Process for making an absorbent article comprising a topsheet/acquisition layer laminate
A process of making an absorbent article is disclosed. A liquid permeable topsheet web extending substantially continuously in a machine direction a backsheet web, and an intermediate layer are provided. The topsheet web has first and second surfaces. The backsheet web extends substantially continuously in the machine direction. The intermediate layer has a first and second surface. The topsheet and intermediate layer are aligned in a face to face relationship such that the second surface of the topsheet in in contact with the first surface of the intermediate layer and simultaneously mechanically deformed which combines the topsheet with the intermediate layer. The topsheet web and intermediate layer are nested together such that a majority of the three-dimensional protrusions formed in the topsheet web coincide with and fit together with a majority of the three-dimensional protrusions formed in the intermediate layer to provide a topsheet/intermediate layer laminate web having three-dimensional protrusions.
