A disposable absorbent liner for use in a crotch portion of underwear comprising: a cover layer having a top surface and an opposite bottom surface and comprising a mixture of hydrophilic microfibers and hydrophobic microfibers; a removable backing layer; and a liquid impermeable baffle layer having a top surface and an opposite bottom surface with the baffle layer being disposed between the cover layer and the backing layer; characterised in that: a quantity of hydrophilic microfibers and hydrophobic microfibers are located at the top surface and a larger quantity of hydrophobic microfibers are located at the top surface than are a quantity of hydrophilic microfibers located at the top surface based on a total weight of the mixture of microfibers in the cover layer, wherein the cover layer has a Z-direction gradient in microfiber composition, such that the top surface of the cover layer is more hydrophobic that the bottom surface of the cover layer; the cover layer is a nonwoven integral matrix of the mixture of microfibers; and the absorbent liner has: a low profile, a thickness in the range of 1 mm to greater than 0 mm and an Absorbent Capacity in the range of 2 grams to 10 grams; and/or a low profile, a thickness in the range of 1 mm to greater than 0 mm and an Absorbent Intake Rate of less than 30 seconds. a cover layer having a top surface and an opposite bottom surface and comprising a mixture of hydrophilic microfibers and hydrophobic microfibers; a removable backing layer; and a liquid impermeable baffle layer having a top surface and an opposite bottom surface with the baffle layer being disposed between the cover layer and the backing layer; characterised in that: a quantity of hydrophilic microfibers and hydrophobic microfibers are located at the top surface and a larger quantity of hydrophobic microfibers are located at the top surface than are a quantity of hydrophilic microfibers located at the top surface based on a total weight of the mixture of microfibers in the cover layer, wherein the cover layer has a Z-direction gradient in microfiber composition, such that the top surface of the cover layer is more hydrophobic that the bottom surface of the cover layer; the cover layer is a nonwoven integral matrix of the mixture of microfibers; and a quantity of hydrophilic microfibers and hydrophobic microfibers are located at the top surface and a larger quantity of hydrophobic microfibers are located at the top surface than are a quantity of hydrophilic microfibers located at the top surface based on a total weight of the mixture of microfibers in the cover layer, wherein the cover layer has a Z-direction gradient in microfiber composition, such that the top surface of the cover layer is more hydrophobic that the bottom surface of the cover layer; the cover layer is a nonwoven integral matrix of the mixture of microfibers; and the absorbent liner has: a low profile, a thickness in the range of 1 mm to greater than 0 mm and an Absorbent Capacity in the range of 2 grams to 10 grams; and/or a low profile, a thickness in the range of 1 mm to greater than 0 mm and an Absorbent Intake Rate of less than 30 seconds. a low profile, a thickness in the range of 1 mm to greater than 0 mm and an Absorbent Capacity in the range of 2 grams to 10 grams; and/or a low profile, a thickness in the range of 1 mm to greater than 0 mm and an Absorbent Intake Rate of less than 30 seconds.
