Abstract

Paper having a reduced smolder and burn tendencies for producing wrappers for smoking articles, for example cigarettes, is provided by adding phyllosilicates with water-absorbing capacities to the paper.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A paper for smoking articles comprising: 
 cellulose;    fillers; and    burn inhibitors that are water-emitting pigments of the mineral group smectites.    
     
     
         2 . The paper according to  claim 1 , wherein the burn inhibitors belong to the montmorillonite group.  
     
     
         3 . The paper according to  claim 1 , wherein the burn inhibitors belong to the hectorite group.  
     
     
         4 . The paper according to  claim 1 , wherein the burn inhibitors belong to the beidellites group.  
     
     
         5 . The paper according to  claim 1 , wherein the burn inhibitors belong to the nontronite group.  
     
     
         6 . The paper according to  claim 1 , wherein the burn inhibitors belong to the stevensite group.  
     
     
         7 . The paper according to  claim 1 , wherein the burn inhibitors belong to the saponite group.  
     
     
         8 . The paper according to  claim 1 , wherein the water-emitting pigments have a specific surface area according to BET between 5 and 1000 m 2 /g.  
     
     
         9 . The paper according to  claim 1 , wherein the water-emitting pigments have a pore volume between 0,01 and 1,0 ml/g.  
     
     
         10 . The paper according to  claim 1 , wherein the water-emitting pigments have a water intake capacity of between 1 and 60%.  
     
     
         11 . The paper according to  claim 1 , wherein the water-emitting pigments have DTA-peaks for the disposal of the adsorptively bound water in a temperature range of between 100° and 200° C.  
     
     
         12 . The paper according to  claim 1 , wherein air permeability of the paper is between 0,5 and 20 CU.  
     
     
         13 . The paper according to  claim 1 , wherein the water-emitting pigments have been produced synthetically.  
     
     
         14 . The paper according to  claim 1 , wherein the water-emitting pigments are of natural origin.  
     
     
         15 . The paper according to  claim 1 , wherein the water-emitting pigments are distributed evenly in or on the paper.  
     
     
         16 . The paper according to  claim 1 , wherein the water-emitting pigments are distributed in or on the paper in a zone-shaped, strip-shaped, and/or cross-shaped manner.  
     
     
         17 . The paper according to  claim 1 , wherein the paper is used for producing filter wrappers or mouth pieces.  
     
     
         18 . The paper according to  claim 1 , wherein the smoking article is a cigarette.  
     
     
         19 . The paper according to  claim 1 , wherein the fillers are selected from the group consisting of CaCO 3 , PCC, GCC, titanium dioxide, calcined porcelain clay, and combinations thereof;  
     
     
         20 . A paper for cigarettes, the paper comprising burn inhibitors added to the paper, the burn inhibitors being smectites and reduce a burn tendency of the paper.  
     
     
         21 . A method of manufacturing paper for smoking articles, the method comprising: 
 providing paper for the smoking articles, the paper partially encompassing tobacco therein in a final manufactured state; and    adding burn inhibitors, which are water-emitting pigments, to the paper, the burn inhibitors being smectites.
