Abstract
A diaper structure with enhanced softness attributes is disclosed. The diaper structure may include an innermost layer formed of a first nonwoven web, and an outermost layer formed of a second nonwoven web. The first and second nonwoven webs may have a combined basis weight of at least about 30 gsm. The ratio of the first web basis weight to the second web basis weight may range from 30/70 to 70/30.
Claims35
A disposable diaper, comprising:
- a topsheet comprising a first nonwoven web;
- a backsheet comprising a second nonwoven web which forms a portion of the outermost layer of the diaper;
- and
- an absorbent core comprising a particulate polymer material disposed between the topsheet and the outermost layer, wherein the absorbent core is substantially cellulose free;
- wherein the first nonwoven web and the second nonwoven web have a combined basis weight of at least 50 gsm, and wherein a first basis weight of the first nonwoven web is different than a second basis weight of the second nonwoven web;
- wherein the ratio of the basis weight of the first nonwoven web to the basis weight of the second nonwoven web is from 30/70 to 70/30;
- and
- wherein each of the first nonwoven web and the second nonwoven web has a Compression Loft of at least 30%, according to the Compression Loft Test.

A disposable diaper, comprising:
- an innermost layer comprising a first nonwoven web;
- an outermost layer comprising a second nonwoven web;
- and
- a substantially cellulose free absorbent core positioned between the innermost layer and the outermost layer, wherein the substantially cellulose free absorbent core comprises:
- a first substrate;
- a second substrate;
- a thermoplastic adhesive material;
- and
- a particulate polymer material, wherein the thermoplastic adhesive material and the particulate polymer material are positioned intermediate the first and second substrates;
- wherein the first nonwoven web and the second nonwoven web have a combined basis weight of at least 40 gsm, and wherein a basis weight of the first nonwoven web is less than a basis weight of the second nonwoven web;
- wherein the ratio of the basis weight of the first nonwoven web to the basis weight of the second nonwoven web is from 40/60 to 60/40;
- and
- wherein each of the first nonwoven web and the second nonwoven web has a Compression Loft of at least 30%, according to the Compression Loft Test.
