Abstract

一种打孔无纺布（1）及其生产方法，由二层开孔无纺布（11、12）的立体漏斗形开孔（C、D）套孔重叠复合而成；所述第一层开孔无纺布（11）具凸起部分（B）与凹入部分（A），所述的凸起部分（B）具有内部空间（E）；所述第二层开孔无纺布（12）的上侧与第一层开孔无纺布（11）的凹入部分（A）的下侧进行粘结；所述套孔重叠的立体漏斗形开孔（C、D）贯穿第一层开孔无纺布（11）和第二层开孔无纺布（12）。第一层开孔无纺布（11）凸起部分（B）的内部连续空间与第二层开孔无纺布（12）之间形成有气流通道，为无纺布的渗透提供一个渗透通道，进而加快液体，排泄物软便渗透和减少残留，提供气流的内外循环，减少湿闷感。在加工中采用针尖的穿刺工序将第一层开孔无纺布（11）紧密的贴附在凸辊（N）上，有效防止复合加工过程中两层无纺布的错位，又简化了工艺，节省了制造成本。
