Absorbent laminated material

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.

         28 . The absorbent laminated material of  claim 21 , wherein the absorbent laminated material is a dry wipe. 
     
     
         29 . The absorbent laminated material of  claim 21 , wherein the absorbent laminated material is a premoistened wipe. 
     
     
         30 . The absorbent laminated material of  claim 29 , wherein the absorbent laminated material is premoistened with a solution selected from: water, alcohol, cleaning solutions, or combinations thereof. 
     
     
         31 . A disposable cleaning article comprising:
 a first spunbond nonwoven layer comprising a thermoplastic polymer;   a second spunbond nonwoven layer comprising a thermoplastic polymer;   a cellulose layer;
 wherein the cellulose layer is free of bonding agents; 
 wherein the cellulose layer is arranged between and ultrasonically bonded to the first spunbond nonwoven layer and second spunbond nonwoven layer; 
 wherein the cellulose layer comprises a basis weight between about 10 gsm and 80 gsm; and 
 wherein a cellulose layer weight is in a ratio of from 1:1 to 4:1 to a total weight of the first spunbond nonwoven layer and the second spunbond nonwoven layer. 
   
     
     
         32 . The disposable cleaning article of  claim 31 , wherein the disposable cleaning article is a premoistened wipe. 
     
     
         33 . A method of making an absorbent laminated material, the method comprising:
 providing a bottom spunbond nonwoven layer comprising a thermoplastic polymer on a bonding station;   arranging a cellulose layer free of bonding agents that extends continuously along the surface of the bottom spunbond nonwoven layer;   performing first ultrasonic treatment to bind the bottom spunbond nonwoven layer and the cellulose layer;   arranging a top spunbond nonwoven layer along the continuous surface of the cellulose layer;   performing a second ultrasonic treatment to bind the top spunbond nonwoven layer to the cellulose layer; and   passing the arranged layers through an anvil,
 wherein the anvil imparts a pattern on the absorbent laminated material. 
   
     
     
         34 . The method of making the absorbent laminated material of  claim 33 , wherein the ultrasonic bonding is performed a rate from about 25 meters/minute to about 700 meters/minute. 
     
     
         35 . The method of making the absorbent laminated material of  claim 33 , wherein the ultrasonic bonding is performed at a pressure of about 500 N to about 5000 N. 
     
     
         36 . The method of making the absorbent laminated material of  claim 33 , the method further comprising:
 producing the bottom spunbond nonwoven layer and top spunbond nonwoven layer as a spunbond web that includes a sheath and core arrangement,
 wherein the core is comprised of polyester or polypropylene and the core is surrounded by a polyethylene sheath. 
   
     
     
         37 . The method of making the absorbent laminated material of  claim 33 , wherein the absorbent laminated material is a dry wipe.
