Abstract
Absorbent laminated materials that include two spunbond nonwoven layers with a cellulose layer arranged in between the spunbond nonwoven layers are disclosed. The different layers of the absorbent laminated material are bonded through an ultrasonic treatment, and can further undergo an embossing step. In addition, the absorbent laminated materials may be used as disposable wiping products, among other applications.
