然后，进行铺网的操作，得到第一纤维絮片前体。具体的，按工艺要求进行门幅和克重调节以确保产品质量，将梳理机输出的纤维网均匀的折叠，铺设至所需的宽度及厚度。其中，铺网机斜帘38.25Hz、环帘23.9Hz、底帘27Hz、往复帘40Hz。
经过主开松后，第二混合纤维在高集棉箱(高集棉箱尺寸为200cm*280cm*170cm)中形成密实的第二筵棉，并使原料进行囤积，以确保梳理时能均匀的供给，保证克重的稳定。
接着，第二筵棉通过给棉机以750rpm的速度进入双锡林梳理机进行梳理成网，具体的，把开松好的原材料进入到转速1200r/min锡林，48Hz的道夫进行梳理成型，进行精细分解将第二筵棉拉直成型，加工成基本上由单纤维组成的定量纤网，输送给后道工序。
然后，进行铺网的操作，得到第二纤维絮片前体。具体的，按工艺要求进行门幅和克重调节以确保产品质量，将梳理机输出的纤维网均匀的折叠，铺设至所需的宽度及厚度。其中，铺网机斜帘38.25Hz、环帘23.9Hz、底帘27Hz、往复帘40Hz。
经过主开松后，第三混合纤维在高集棉箱(高集棉箱尺寸为200cm*280cm*170cm)中形成密实的第三筵棉，并使原料进行囤积，以确保梳理时能均匀的供给，保证克重的稳定。
接着，第三筵棉通过给棉机以750rpm的速度进入双锡林梳理机进行梳理成网，具体的，把开松好的原材料进入到转速1200r/min锡林，48Hz的道夫进行梳理成型，进行精细分解将第三筵棉拉直成型，加工成基本上由单纤维组成的定量纤网，输送给后道工序。
然后，进行铺网的操作，将第三筵棉铺设于所述第二纤维絮片前体之上，得到第一纤维絮片前体/第二纤维絮片前体/第三纤维絮片前体复合而成的分层结构填充物前体。具体的，按工艺要求进行门幅和克重调节以确保产品质量，将梳理机输出的纤维网均匀的折叠，铺设至所需的宽度及厚度。其中，铺网机斜帘38.25Hz、环帘23.9Hz、底帘27Hz、往复帘40Hz。
将所述分层结构填充物前体在牵引速率为1250rpm的五辊牵引机中进行牵引，保证产品的平整度。
牵引结束后，将铺好网的产品进行水分的挥发，确保产品的干燥，再对产品里的粘丝进行溶解凝固，确保产品的拉力和形状。所述烘干的温度优选为170℃。
干燥结束后，将所述产品进行烫光，以增加产品的粘合和牢度，确保手洗不分离和跑毛。其中，所述烫光的温度为200℃，所述烫光机的转速为45Hz。
烫光后，将所述经过烫光后的分层结构填充物前体用转速1430Y/min的风机进行吹风内圈冷却进行降温定型，得到分层结构填充物。
最后，以每22转为一米的定量并以1200rpm的速度进行成卷，得到产品。对产品进行性能测定，结果见表4，表4为实施例29～56制备的三层结构填充物的性能测定结果。
