The present invention protects a sanitary napkin having a longitudinal central axis, a pair of transverse sides and a pair of longitudinal sides extending therebetween, a front edge and a rear edge; the fold back wings extending transversely beyond the longitudinal sides of the sanitary napkin and comprising a transverse axis dividing said fold back wings into two substantially equal halves in a longitudinal direction parallel to the longitudinal central axis, the fold back wings are positioned along the sanitary napkin such that an overall length ratio correspondig to the following equation L*(L1/L2) is greater than 29, where L is the total length of the sanitary napkin taken along the central longitudinal axis, L1 is the distance from the transverse central axis of the fold back wings to the front edge, and L2 is the distance from the transverse central axis of the fold back wings to the rear edge; and in that the said transverse axis is offset from a sanitary napkin transversal axis crossing the midpoint of said total length L.

The invention relates to an absorbent matrix intended for use in a disposable absorbent item, said matrix comprising an upper surface and a lower surface, a front portion and a rear portion, two longitudinal edges and two transverse edges, and being formed of three layers: an upper layer, an intermediate layer and a lower layer. The upper and lower layers contain less than 25% super absorbent material. The intermediate layer has three areas with different specific weights: one receiving and distribution area, one or more transition areas and one or more anti-leakage areas.

The invention relates to a non-woven cloth to be laminated to a polyethylene layer, such that a. it is formed by a mixture of hydrophobic and hydrophilic polypropylene fibres; b. it is produced by means of a carding process followed by thermal bonding; c. during the thermal bonding, at least 15% of the area thereof is etched; and d. it has a minimum base weight of 13 gr/m 2
摘要:
A disposable absorbent article, comprising a pervious topsheet, an impervious backsheet, an absorbent core disposed between the topsheet and the backsheet, the absorbent core having two longitudinal edges and two transverse edges, elastic waist bands and a fastening system; the article has a front zone, a back zone and a crotch zone, as well as two longitudinal edges and two transverse edges. The article also has two anti-leakage cuffs disposed over the topsheet, the cuffs having a fixed edge attached, by means of a first joint, along the entire length of the diaper over the longitudinal edges of the absorbent core, and an adjustment edge attached, by means of a second joint, which in turn consists of four joints: two in the upper longitudinal ends and two in the lower longitudinal ends, to the topsheet of the article, such that the second joint is oriented towards the longitudinal edges of the article.

摘要:
A non-woven fabric to be used in a disposable absorbent article is disclosed, to which a formula is added during its manufacturing process, either to change its affinity to water and/or to provide same with any desired characteristic, said formula containing an indicator means such that the formula can be detected along the entire length and width of the fabric during the manufacturing process thereof, without the need of carrying out laboratory tests. The indicator means can be an optical indicator, a thermal indicator or a coloring agent.
