摘要:
Disclosed herein are elastic laminate materials. The elastic laminate materials are laminates of extensible nonwoven fibrous webs and thermoplastic elastic materials. The laminate may be a two-layer composite material having a single nonwoven fibrous web bonded to one side of the thermoplastic elastic material, or it may be a three-layer composite having a nonwoven fibrous web bonded to each side of the thermoplastic elastic material. The extensible nonwoven fibrous webs may be carded staple fiber webs of staple fibers. The thermoplastic elastic material may be single-layer or multi-layer elastic films, or elastic fibrous layers. Where single- or multi-layer elastic films are used, the films may be breathable films. The elastic material, or some of the staple fibers, or both, may be selected such that the carded staple fiber webs are thermally compatible with the thermoplastic elastic material to facilitate laminate bonding. Processes for forming the elastic laminate material are also disclosed.
摘要(中):
本文公开了弹性层压材料。 弹性层压材料是可伸长的非织造纤维网和热塑弹性材料的叠层。 层压体可以是具有与热塑性弹性材料的一侧结合的单个非织造纤维网的双层复合材料,或者可以是具有粘合到热塑性弹性材料的每一侧的非织造纤维网的三层复合材料。 可伸展的非织造纤维网可以是短纤维的梳理短纤维网。 热塑性弹性材料可以是单层或多层弹性膜或弹性纤维层。 当使用单层或多层弹性膜时,膜可以是透气膜。 可以选择弹性材料或一些短纤维或两者,使得梳理的短纤维网与热塑性弹性材料热相容以便于层压结合。 还公开了用于形成弹性层压材料的方法。
