    • A gradient density padding material includes a single layer of nonwoven material having at least one surface processed to form a portion of a thickness thereof having a density increased with respect to a remaining portion of the thickness thereof. The single layer of nonwoven material after processing has an airflow resistance within the range of 200-4000 MKS Rayls, wherein said single layer of nonwoven material has an enhanced acoustic performance. A method of making a gradient density padding material having an enhanced acoustic performance includes the steps of providing a single layer of nonwoven material and processing at least one surface of the single layer of nonwoven material to form a portion of a thickness thereof having a density increased with respect to a remaining portion of the thickness thereof. The single layer of nonwoven material after processing has an airflow resistance within the range of 200-4000 MKS Rayls.
    • 梯度密度填充材料包括单层非织造材料,其具有至少一个表面被处理以形成其厚度的一部分,其密度相对于其厚度的剩余部分增加。 处理后的单层非织造材料具有在200-4000MMS雷尔范围内的气流阻力,其中所述单层非织造材料具有增强的声学性能。 制备具有增强的声学性能的梯度密度填充材料的方法包括以下步骤:提供单层非织造材料并且处理单层非织造材料的至少一个表面以形成具有密度增加的一部分厚度 相对于其厚度的剩余部分。 处理后的单层非织造材料具有在200-4000MMS雷尔范围内的气流阻力。
