Estimating the term…
The present invention discloses a disposable or wearable absorbent article (1) that includes one or more elastomeric strand(s) (14) and/or strip(s) (16) on/in the backsheet (12) layer, localized in the absorbent core (10) region. The absorbent article (1) is preferably a baby diaper, an incontinence diaper, a pant or a pull up garment. The article may have a topsheet (6), a backsheet (12) and absorbent core (10) disposed between the topsheet (6) and backsheet (12), and a pair of longitudinal side edges. Elastomeric strand(s) (14) and/or strip(s) (16) is attached in longitudinal axis of the backsheet (12) of the absorbent article (1) in stretched form, whereby backsheet takes a crinkled form when it is in relaxed state. The absorbent article (1) fits better on users buttocks without sagging when the article is being worn.
1- An absorbent article (1) having longitudinal axis (X) and lateral axis (Y) comprising, a backsheet (12), a topsheet (6) and an absorbent core (10) layered between the topsheet (6) and the backsheet (12), wherein said backsheet (12) comprises;
2- An absorbent article (1) according to claim 1, wherein said elastomeric strip(s) (16) is attached on/in the polymeric film layer (18), preferably on the interior surface or the exterior surface of said polymeric film layer (18), more preferably on the interior surface of the polymeric film layer (18).
3- An absorbent article (1) according to claim 2, wherein, said elastomeric strip(s) (16) is attached on/in said polymeric film layer (18) of the backsheet (12) in longitudinal axis (X) in stretched form enabling up to 50% stretch in longitudinal direction of the length (L) of said absorbent article (1).
4- An absorbent article (1) comprising elastomeric strip(s) (16) according to claim 1, wherein the length of said elastomeric strip(s) (16) extends between 5 to 95%, preferably between 20 to 70% of the length (L) of the absorbent article (1).
5- An absorbent article (1) comprising elastomeric strips (16) according to claim 1, wherein the distance between two elastomeric strips (16) (B), is at least 5 mm, preferably at least 10 mm.
6- An absorbent article comprising elastomeric strip(s) (16) having a width (W) according to claim 1, wherein the width (W) of said elastomeric strip is at most 80% of the width (W) of the absorbent core (10), preferably at most 40%, more preferably at most 20% of the width (W) of the absorbent core (10).
7- An absorbent article (1) comprising elastomeric strand (14) according to claim 1, wherein said elastomeric strand (14) is formed of an elastic material comprising styrene block copolymers, polyesters, polyurethanes, polyethers and polyether block copolymers, latex, rubber based polymers or mixtures thereof, preferably polyurethane.
8- An absorbent article (1) comprising elastomeric strand(s) (14) formed of polyurethane according to claim 7, wherein the diameter of said polyurethane elastomeric strand (14) is between 200 to 800 micron, preferably between 400 to 600 micron.
9- An absorbent article (1) comprising elastomeric strand(s) (14) according to claim 1, wherein said elastomeric strand(s) (16) is attached on the backsheet (12) with a hot melt adhesive.
10- An absorbent article (1) comprising elastomeric strip(s) (16) comprising elastomeric strand(s) (14) according to claim 1, wherein the backsheet (12) comprises preferably two elastomeric strips (16) located centrally in the absorbent core width range, comprising at least one elastomeric strand (14).
11- A process of manufacturing of absorbent article (1) according to claim 1, comprising the steps;
12- An absorbent article (1) according to claim 1, said absorbent article (1) is used as disposable or wearable article comprising baby diapers, incontinence diapers, pants or pull ups.
