Stretchable laminate having a stretched or SELF processed layer, a method of manufacturing the same, and a disposable absorbent article including the same
Disclosed is a stretchable laminate having an improved texture and a method for producing the same. The elastic laminate can include two nonwoven fabric layers sandwiching an elastic member, and the elastic member can be pre-woven such that Z-direction folds of the nonwoven material are imparted to the laminate when the laminate is in a relaxed state It is incorporated into the laminate in a strained state. At least one of the nonwoven layers may be stretched in small increments or SELF processed to add ridge and valley patterns to the material that bonds to the pleats and further improve the thickness and texture of the laminate.改善されたテクスチャーを有する伸縮性積層体及びその製造方法が開示される。伸縮性積層体は、弾性部材を挟む２つの不織布層を含むことができ、積層体が弛緩状態にあるときに不織布材料のＺ方向のひだが積層体に付与されるように、弾性部材は予ひずみが与えられた状態で積層体に組み込まれている。不織布層の少なくとも一方は、小刻みに延伸され、又はＳＥＬＦ加工されて、ひだと結合する材料に山部及び谷部のパターンを付加し、更には積層体の厚み及びテクスチャーを改善させることができる。
