- نبذة مختصرة :
A nonwoven substrate includes individual fibers each having a fiber surface and a fiber diameter, wherein a portion of the individual fibers include a micro-embossed pattern, and wherein the micro-embossed pattern includes pattern elements equal to or smaller than the fiber diameter. The pattern elements can be recessed into and/or extend out of the fiber surface, and the nonwoven substrate can include polypropylene or polyethylene. A disposable absorbent article includes a nonwoven substrate having individual fibers each having a fiber surface and a fiber diameter, wherein a portion of the individual fibers include a micro-embossed pattern, and wherein the micro-embossed pattern includes pattern elements equal to or smaller than the fiber diameter.

10. The nonwoven substrate of claim 9 , wherein the pattern elements are 10 microns or less.
- Claim:
11. The nonwoven substrate of claim 9 , wherein a contact angle of the nonwoven substrate is elevated by 5 or more degrees when compared to the same nonwoven substrate without a micro-embossed pattern.
- Claim:
12. The nonwoven substrate of claim 9 , wherein a contact angle of the nonwoven substrate is elevated by 10 or more degrees when compared to the same nonwoven substrate without a micro-embossed pattern.
- Claim:
13. A disposable absorbent article comprising a nonwoven substrate having individual fibers each having a fiber surface and a fiber diameter, wherein a portion of the individual fibers include a micro-embossed pattern, and wherein the micro-embossed pattern includes pattern elements equal to or smaller than the fiber diameter, wherein the micro-embossed pattern has a pattern roughness, and wherein the pattern roughness is greater than 1.5, the nonwoven substrate having a substrate density of less than 0.12 g/cc, and wherein the nonwoven substrate has a pattern coverage of at least 20% based on the projected fiber surface area visible from above.
- Claim:
14. The disposable absorbent article of claim 13 , wherein the disposable absorbent article is a feminine hygiene product, an infant care product, a child care product, an incontinence product, or a wound dressing.
- Claim:
15. The disposable absorbent article of claim 13 , wherein a contact angle of the nonwoven substrate is elevated by 5 or more degrees when compared to the same nonwoven substrate without a micro-embossed pattern.
- Claim:
16. The disposable absorbent article of claim 13 , wherein a contact angle of the nonwoven substrate is elevated by 10 or more degrees when compared to the same nonwoven substrate without a micro-embossed pattern.
