    • A method to reduce the noise produced by movement of a substrate is disclosed. One embodiment of the method includes applying a noise-reducing coating material at an add-on rate of at least about three grams per square meter to a target region of a first surface of a substrate so as to substantially completely coat the target area, wherein the noise-reducing coating material comprises a polymeric material. Also disclosed is a reduced-noise composite material that can be employed in a disposable personal care device. The reduced-noise composite material can include a substrate layer which defines a first surface having a surface area and a target area, and a noise-reducing layer which substantially completely coats the target region. The noise-reducing layer has a basis weight of at least about three grams per square meter. Also disclosed is a reduced-noise disposable personal care device, which may in particular embodiments be a disposable absorbent article. One embodiment of the disposable absorbent article includes a body-side liner and a garment-side outer cover. The outer cover includes a liquid-impermeable substrate layer comprised of a thermoplastic, polymeric material and which defines a first surface having a surface area and a target area. The outer cover further includes a noise-reducing layer which substantially completely coats the target region, and which has a basis weight of at least about three grams per square meter. The disposable absorbent article further includes an absorbent assembly disposed between the body-side liner and the garment-side outer cover.
    • 公开了一种降低由衬底移动产生的噪声的方法。 该方法的一个实施方案包括以至少约3克/平方米的附加速率将一种降噪涂料施用于基材的第一表面的目标区域,以便基本上完全涂覆目标区域,其中 降噪涂料包括聚合材料。 还公开了可用于一次性个人护理装置中的降低噪音的复合材料。 降低噪声的复合材料可以包括限定具有表面积和目标区域的第一表面的基底层和基本上完全涂覆目标区域的降噪层。 减噪层的基重至少约为每平方米3克。 还公开了一种减少噪音的一次性个人护理装置,其特别可以是一次性吸收制品。 一次性吸收制品的一个实施例包括主体侧衬里和衣服侧外盖。 外盖包括由热塑性聚合物材料构成的液体不可渗透的基底层,并且限定具有表面积和目标区域的第一表面。 外盖还包括基本上完全涂覆目标区域并且具有至少约3克/平方米的基重的减噪层。 一次性吸收制品还包括设置在身体侧衬里和衣服侧外罩之间的吸收组件。
