DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to an absorbent article comprising periphery of the absorbent article comprising two longitudinal sides and two lateral sides extending transversely to the longitudinal sides, and elastic member comprising a net-like substrate of interconnected elastic strands.
The invention also relates to an absorbent article comprising longitudinal sides and two lateral sides extending transversely to the longitudinal sides, the longitudinal sides each comprising a first end part and a second end part, the end parts of each longitudinal side being mutually joined in a respective side panel area so that the lateral sides form an endless waistband or a part thereof, the part of each longitudinal side that is located between the end parts, forming a respective endless legcuff or a part thereof, backsheet, the elastic member comprising a net-like substrate of interconnected elastic strands.
BACKGROUND OF THE INVENTION
Such an absorbent article is known from the American patent U.S. Pat. No. 4,407,284.
In this patent a net-like elastic member is disclosed having longitudinal strands that are intermittently mutually connected by a number of transverse strands. The elastic member is placed between the backsheet and the topsheet of an absorbent article, in particular a diaper. The elastic substrate is placed in parallel with and in the proximity of the longitudinal sides to provide an elastic leg cuff, or in parallel with and in the proximity of the lateral sides to provide an elastic waist feature. The elastic member is placed between the topsheet and the backsheet in its streched condition, the topsheet being laminated to the backsheet through the the open areas in the elastic member. Upon relaxation of the elastic member, the topsheet and the backsheet are gathered only for those parts of the elastic member that are transversely connected. The modulus of elasticity at 100% elongation of the elastic member, that can be made of any strechable film material of a preferred thickness of between 0.13 mm and 0.50 mm, preferably lies between 1.4 and 140 Kgcm.sup.-2.
An absorbent article of the above mentioned kind, can at the areas where the elastic member is placed between the topsheet and the backsheet, be relatively uncomfortable to the skin because the glue, fixing the topsheet to the backseet, can reduce softness or the fibrous nature of the topsheet. Furthermore, the direction of stretch is confined to the longitudinal direction of the elastic member, the bonding of the topsheet to the backsheet allowing no stretch perpendicular thereto.
OBJECTS OF THE INVENTION
It is an object of the invention to provide for an absorbent article comprising an elastic member having good fluid-handling properties and being comfortable during use.
It is another object of the invention to provide for an absorbent article comprising an elastic member giving an improved fit of the absorbent article during use.
It is another object of the invention to provide for an elastic member that can be placed on a body-facing side of the backsheet, or between the topsheet and the backsheet, in a non-stretched condition and which can be firmly attached to the topsheet or the backsheet using a relatively small amount of glue.
It is again anoter object of the invention to provide for an absorbent article comprising an elastic member which, when placed between the topsheet and the backsheet, allows for good adhesion thereto while at the same time enabling a relatively large freedom of movement of the combined topsheet and backsheet.
SUMMARY OF THE INVENTION
An absorbent article according to the invention is characterized in that at least one layer of fibers is pre-bonded to a body-facing side of the substrate.
Because the fibrous nature of the surface of the elastic member that is located adjacent to the skin of the wearer of the absorbent article, provides for sufficient resiliency and bulk, it is comfortable to the wearer. Contrary to the elastic member disclosed in the prior art, wherein the topsheet is di
