Abstract
The present invention relates to a nonwoven comprising a first layer comprising a first fiber and a second fiber, and a second layer comprising a third fiber; wherein the first fiber is hydrophobic and the second fiber is hydrophilic, and wherein the second layer is more hydrophilic than the first layer; a method for manufacturing the nonwoven according to the present invention; and an absorbent article comprising a topsheet; and a backsheet joined to the topsheet, wherein the topsheet comprises the nonwoven according to the present invention.
Claims18
A nonwoven sheet comprising
- a first layer comprising a first fiber and a second fiber, and
- a second layer comprising a third fiber,
- wherein the first fiber is hydrophobic and the second fiber is hydrophilic,
- wherein the third fiber is hydrophilic, and
- wherein the second layer is more hydrophilic than the first layer, and
- wherein a total surface area of the first fiber is from about 30 percent to about 60 percent of a total surface area of fibers of the first layer.
A method for manufacturing a nonwoven comprising the steps of:
- forming a first fibrous web comprising a first fiber and a second fiber wherein one of the first and second fibers are a composite fiber,
- forming a second fibrous web comprising a third fiber which is a composite fiber,
- forming a complex fibrous web by overlaying the first fibrous web on the second fibrous web;
- and
- subjecting the complex fibrous web to thermal treatment in order to thermal bond at least a portion of the first, second, and third fibers,
- wherein the first fiber is hydrophobic and the second fiber is hydrophilic, and
- wherein the second layer is more hydrophilic than the first layer, and wherein a total surface area of the first fiber is from about 30 percent to about 60 percent of a total surface area of fibers of the first layer.
