Claims18
An absorbent article comprising a top sheet, a backing sheet and an absorbent core between the top sheet and backing sheet wherein the top sheet comprises about 20 wt % to about 95 wt % of hydrophobic cotton based on the total weight of the top sheet and about 5 wt % to about 80 wt % of hydrophilic cotton based on the total weight of the top sheet.
A sanitary napkin comprising a top sheet, an absorbent core and backing sheet wherein the absorbent core exhibits a modified hourglass shape comprising a front bulb area with a front terminal end, a rear bulb area with a rear terminal end and a neck area connecting the front bulb area longitudinally opposite the front terminal end and the rear bulb area longitudinally opposite the rear terminal end wherein a maximum width of the front bulb area (Wa1) is about 50 mm to about 110 mm;
- a maximum width of the rear bulb area (Wa3) is about 50 mm to about 120 mm and a minimum width (Wa2) which is present in the neck area is about 30 mm to about 75 mm with the proviso that Wa3 is greater than or equal to Wa1 and Wa1 and Wa3 are greater than Wa2 and a longitudinal distance from the front terminal end of the front bulb area to Wa2 or a mid-point of the neck area is less than the longitudinal distance from the rear terminal end of the rear bulb area to Wa2 or the mid-point of the neck area.
An sanitary napkin comprising:
- (a) a top sheet comprises:
- (i) about 50 wt % to about 85 wt % of hydrophobic cotton based on the total weight of the top sheet;
- (ii) about 15 wt % to about 50 wt % of hydrophilic cotton based on the total weight of the top sheet and a basis weight of about 22.5 to about 70 grams per square meter;
- (b) a backing sheet,
- (c) an absorbent core between the top sheet and backing sheet comprising at least 90 wt % cotton, a basis weight of about 150 to about 450 grams per square and wherein the absorbent core is free of any superabsorbent polymeric material and the absorbent core exhibits a modified hourglass shape comprising a front bulb area with a front terminal end, a rear bulb area with a rear terminal end and a neck area connecting the front bulb area opposite the front terminal end and the rear bulb area opposite the rear terminal end wherein a maximum width of the front bulb area (Wa1) is about 50 mm to about 110 mm;
- a maximum width of the rear bulb area (Wa3) is about 50 mm to about 120 mm and a minimum width (Wa2) which is present in the neck area is about 30 mm to about 75 mm with the proviso that Wa3 is greater than or equal to Wa1 and Wa1 and Wa3 are greater than Wa2 and a longitudinal distance from the front terminal end of the front bulb area to a mid-point of the neck area that is less than a longitudinal distance from the rear terminal end of the rear bulb area to the mid-point of the neck area;
- and
- (d) at least one wing extending laterally from the top sheet and/or backing sheet of each lateral side of the neck area of the modified hourglass design wherein each wing has a width (Ww) wherein Ww is a length from a lateral outer edge of the absorbent core at the point of minimum width Wa2 in the neck area to a lateral outer most edge of the wing of about 45 mm to about 55 mm and a longitudinal length (Lw) wherein Lw is a longitudinal length of each wing where the wing extends from the neck area of the sanitary napkin and is about 55 mm to about 70 mm.
