一种无纺布，其生产工艺包括以下步骤：
(1)原料加工：将纳米珍珠粉在粘胶纤维纺丝时加入纤维内制成珍珠共混纤维素纤维，将粘合剂加入棉纤维内制成粘胶纤维。
(2)制备外层无纺布纤维网：将上述珍珠共混纤维素纤维、粘胶纤维、桑蚕丝、银纤维、锦纶纤维混合，用无纺布梳理机制成外层无纺布纤维网。
(3)制备内层无纺布纤维网：将上述粘胶纤维、铅化合物、硼化合物、棉纤维混合，用无纺布梳理机制成内层无纺布纤维网。
(4)喷涂：将粘合剂在搅拌釜中搅拌20～30分钟混合均匀，然后加入喷涂装置料筒，通过喷涂工艺将粘合剂均匀的喷到外层无纺布纤维网和内层无纺布纤维网之间，然后通过上下振动无纺布纤维网，使粘合剂快速均匀的渗透到无纺布纤维网中。
(5)低温烘干：将振动处理后的无纺布纤维网进入烘箱进行烘干，无纺布纤维网通过烘箱速度为10～20米/分钟。
(6)将制得的无纺布压延、切边、卷绕、包装。
优选的，所述步骤(1)中的粘合剂为丙烯酸酯类粘合剂。
