Nonwoven substrate for wearable articles
Disclosed is a wearable article continuous in a longitudinal direction and a transverse direction comprising a body-facing surface and a garment-facing surface; wherein at least a portion of the garment-facing surface is a nonwoven substrate material made of fibers having a Roughness (standard deviation of the grayscale image) of at least about 16, preferably at least about 18, more preferably at least about 20; and a fiber diameter of no more than about 22 μm, preferably no more than about 17 μm, more preferably no more than about 15 μm, according to the measurements herein.
1. A pant article continuous in a longitudinal direction and a transverse direction, comprising:
a body-facing surface and a garment-facing surface;
wherein at least a portion of the garment-facing surface is a nonwoven substrate made of fibers having a Roughness (standard deviation of the grayscale image) of at least 16; and a fiber diameter of no more than 22 μm;
an elastic belt region, a crotch region, a waist opening, and two leg openings;
wherein the elastic belt region is a laminate comprising an inner sheet, an outer sheet, and a plurality of elastic bodies configured to stretch the elastic belt region in the transverse direction;
wherein the crotch region has an outer cover layer as the garment-facing surface; and
wherein at least one of the inner sheet, the outer sheet, and the outer cover layer is the nonwoven substrate.
2. The pant article of claim 1 wherein the fiber of the nonwoven substrate has a micro hole surface area of at least 20%.
3. The pant article of claim 1 wherein the fiber of the nonwoven substrate has a hole count/10 μm 2 of at least 560.
4. The pant article of claim 1 wherein the fiber of the nonwoven substrate has an average hole size of at least 0.039 μm 2 .
5. The pant article of claim 1 wherein the fiber of the nonwoven substrate has a diameter of no more than 17 μm.
6. The pant article of claim 1 wherein the nonwoven substrate has a basis weight of at least 17 gsm according to the measurements herein.
7. The pant article of claim 1 wherein the nonwoven substrate is an air-through carded nonwoven made of a bicomponent filament.
8. The pant article of claim 1 wherein the article comprises a central chassis and a ring-like elastic belt comprising a front belt and a back belt; the center of the front belt is joined to a front waist panel of the central chassis, the center of the back belt is joined to a back waist panel of the central chassis, and the remainder of the central chassis forms the crotch region, the front and back belt each having a left side panel and a right side panel where the central chassis does not overlap, and the transverse edges of the front belt and the back belt are joined by a seam to form a waist opening and two leg openings; wherein the front belt and the back belt are discontinuous of each other in the longitudinal direction.
9. The pant article of claim 1 wherein the outer cover layer is the nonwoven substrate.
10. The pant article of claim 1 wherein the outer sheet of the elastic belt region is the nonwoven substrate.
11. The pant article of claim 1 wherein the inner sheet of the elastic belt region is the nonwoven substrate.
12. The pant article of claim 1 having a Stretch Circumference Force of less than 7N according to the measurements herein.
13. The pant article of claim 1 having a Fit Circumference Force of at least 2N according to the measurements herein.
