Abstract
An absorbent article comprising a nonwoven fibrous structure comprising a plurality of synthetic fibers. The synthetic fibers may be associated with one or more hydrophilizing agents. A process for making the nonwoven fibrous structure involves association of the synthetic fibers with one or more hydrophilizing agents.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A method for making a fibrous substrate, the method comprising:
depositing from a headbox onto a Fourdrinier wire a slurry comprising cellulosic fibers, from 10% to 30% synthetic fibers, and from 40 ppm to about 50 ppm of a hydrophilizing agent to form an embryonic web, wherein at least one of the synthetic fibers forms a durable association with the hydophilizing agent; de-watering the embryonic web to form a web having a consistency of at least 50% consistency; adhering the web to a surface of a Yankee dryer; and creping the web off of the Yankee dryer after the web reaches a consistency of at least 90%.
2 . The method of claim 1 , wherein the synthetic fibers are CoPET/PET bicomponent fibers.
3 . The method of claim 1 , wherein said cellulosic fibers comprise Northern Softwood Kraft fibers.
4 . The method of claim 1 , wherein said cellulosic fibers comprise Eucalyptus fibers.
5 . The method of claim 1 , wherein said de-watering step is accomplished at least partially by vacuum assisted drainage.
6 . The method of claim 1 , wherein said de-watering step is accomplished at least partially by through air drying.
7 . The method of claim 1 , wherein said embryonic web is transferred to a photo-polymer fabric.Join the waitlist — get patent alerts
