发明内容
针对上述问题，本发明的目的是提供了一种复合弹性无纺布的制备方法，采用多种弹性性比较强的化纤纤维进行粘结混合，并使用塑料薄膜和树脂膜，进一步加强了所制成的无纺布的弹性，增加了无纺布的应用范围。
本发明采用的技术方案如下：
一种复合弹性无纺布的制备方法，包括以下步骤：S1、将聚氨酯弹性体、聚酯类弹性体、聚酰胺类弹性体、A2B2A型嵌段共聚物、聚醚酯、乙烯和Α—烯烃共聚物混合挤出纤维,采用熔喷法成网法制得无纺布；
S2、将上述的无纺布通过压辊与树脂膜结合，再进行边缘加固，制得所需的弹性无纺布。
所述的Α—烯烃共聚物为1—辛烯，密度小于0.9g\cm3,熔点小于100℃,后期再用射线做交联处理,其断裂伸长率不低于400％,微纤直径小于75Λm,有改进过的熔喷加工性能、较好的力学和弹性性能,具有多种用途。
所述A2B2A型嵌段共聚物中B为弹性段。
与已有技术相比，本发明的有益效果如下：
本发明采用多种弹性性比较强的化纤纤维进行粘结混合，Α—烯烃共聚物为1—辛烯，密度小于0.9g\cm3,熔点小于100℃,后期再用射线做交联处理,其断裂伸长率不低于400％,微纤直径小于75Λm,有改进过的熔喷加工性能、较好的力学和弹性性能,具有多种用途，所得熔喷弹性无纺布具有特殊的强度和良好的弹性，并使用塑料薄膜和树脂膜，进一步加强了所制成的无纺布的弹性，增加了无纺布的应用范围。
具体实施方式
