A sensor system for detecting a property of or within an absorbent article may comprise an absorbent article and an auxiliary article.

The present disclosure relates to an environmentally friendly sanitary napkin including: a permeable inner sheet configured to come into contact with a skin and allow secretions to pass therethrough; an impermeable waterproof outer sheet having the same size and shape as those of the inner sheet and bonded to the inner sheet by fusion; an absorbent pad fixedly inserted between the inner sheet and the waterproof outer sheet and configured to absorb secretions such as menstrual blood that passes through the inner sheet; and an adhesive pad inserted into an appropriate position between the absorbent pad and the waterproof outer sheet, and provided on the absorbent pad and the lower surface of the waterproof outer sheet, and configured to fix the sanitary napkin by adhesion to the inside of underwear, wherein the inner sheet, the waterproof outer sheet, the absorbent pad and the adhesive pad are degradable in water or are biodegradable.

The environmentally friendly sanitary napkin of the present disclosure is degradable by a large amount of water in a septic tank when flushed down a toilet bowl after use, and is biodegradable in soil, thus preventing environmental pollution problems.

In addition, the environmentally friendly sanitary napkin may exhibit antimicrobial effects against harmful bacteria in the vagina and exhibit an excellent effect on sanitariness by suppressing the generation of odor caused by secretions.

Provided is a non-woven fabric which is suitable for cleaning wipers, diapers, food packaging materials, etc., and has excellent water absorption and handling performance. The non-woven fabric according to the present invention contains a thermoplastic biodegradable resin, and is characterized in that fibers constituting the non-woven fabric have crimps, the flexural rigidity index in the mechanical direction (MD) of the non-woven fabric is 7.77-37.4 as defined by the following equation: flexural rigidity index in the mechanical direction (MD)=flexural rigidity (gf.Math.cm) in the mechanical direction (MD)/{basis weight(g/m.sup.2)}.sup.2.5×10.sup.6, and the bulk density of the non-woven fabric is 0.098 g/cm.sup.3 to 0.251 g/cm.sup.3.

A nonwoven fabric. The nonwoven fabric can include a first surface and a second surface and a visually discernible pattern of three-dimensional features on one of the first or second surface. Each of the three-dimensional features can define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property, and wherein in at least one of the microzones, the first region is hydrophobic and the second region is hydrophilic.

An absorbent hygienic article for absorbing body fluids, the article including a liquid permeable topsheet, a backing layer and an absorbent core arranged between the topsheet and the backing layer, the topsheet and the backing layer being made from roll materials. The topsheet or an absorbent layer in the absorbent core is constituted by a cellulosic fibrous web, the fibres in the cellulosic fibrous web being constituted by a mixture of cellulose fibres including regenerated cellulose fibres or natural cellulose staple fibres and cellulose pulp fibres, the cellulosic fibrous web being a foam-formed, hydroentangled fibrous web.

A sanitary pad system includes a first pad and a second pad. The first pad has a first set of fastening tabs and the second pad has a second set of fastening tabs. The two sets of fastening tabs are offset so that, when the two pads are stacked in overlapping relationship on an undergarment, both pads are directly attached to the undergarment with the associated fastening tabs.

A multi-layer absorbent product is provided that includes a first layer that is either liquid permeable or liquid impermeable and a layer of a treated nonwoven, woven or knitted textile material or a treated textured plastic yarn. The layer of textured plastic yarn or of nonwoven, woven or knitted textile material has uniformly spaced deposits of a natural polymer crosslinked to a synthetic polymer in the absence of non-polymeric crosslinking agent, where each of the deposits is a continuous polymer network that covers the textile or plastic underneath the deposit and interpenetrates the network of textile fibers or of plastic pores acting as a scaffold to interconnect the polymer network with the fiber network or with the network of plastic pore walls. A process for preparing the layer of textile material or of textured plastic yarn with uniformly spaced deposits is also provided.

To certainly fix the peripheral portion of a hole to a support sheet without losing flexibility. The above problem is solved by providing a cover nonwoven fabric in which a plurality of holes penetrating front and back surfaces at intervals, and a liquid impervious sheet in which the cover nonwoven fabric is bonded via a hot melt adhesive, in the cover nonwoven fabric, the peripheral portions of the holes are warped portion warped toward the liquid impervious sheet side, at least a tip portion of the warped portion of the cover nonwoven fabric has an adhesive portion bonded to the liquid impervious sheet via the hot melt adhesive, and a portion of the cover nonwoven fabric other than the adhesive portion is not adhered to the liquid impervious sheet.

An absorbent article selected from a sanitary napkin, an incontinence pad and a pantyliner, comprising a topsheet layer a backsheet layer a fastening adhesive applied on the backsheet garment facing surface, wherein at least a portion of said fastening adhesive (PFA) is applied in a pattern and wherein said backsheet layer is a plastic film having a basis weight of less than 20 gsm.

An absorbent article having improved softness signals is disclosed. The article may include a topsheet or a backsheet including a nonwoven web. The web may have a basis weight of 30 gsm or less, may be formed of spunlaid fibers including polyolefin and up to 5 percent by weight TiO.sub.2, and may be impressed with a pattern of bond impressions to a bond area percentage of at least 10 percent forming a pattern of bonded regions and raised regions. The web may have opacity of 42 or greater; have an average height difference between bonded regions and raised regions of at least 280 μm; be hydroengorged; and/or have a cross-machine direction tensile strength of 350 gf/cm. A nonwoven web manufactured to have a suitable combination of such features exhibits an enhanced appearance of softness, soft tactile feel and satisfactory mechanical attributes, while being relatively cost effective.
