Woven fabric filter including flavored sheet and smoking article including the same

Abstract

The present disclosure relates to a woven fabric filter including a flavored sheet and a smoking article including the same, and more particularly, to a woven fabric filter including a flavored sheet fiber that is a fiber obtained by cutting a flavored sheet and that includes a cellulose-based polymer, a plasticizer, and a flavoring material, and to a smoking article including the same.

1 . A woven fabric filter comprising:
 a flavored sheet fiber,   wherein the flavored sheet fiber is a fiber obtained by cutting a flavored sheet, and the flavored sheet comprises a cellulose-based polymer, a plasticizer, and a flavoring material.   
     
     
         2 . The woven fabric filter of  claim 1 , wherein
 the cellulose-based polymer is in an amount of 20% by weight (wt %) to 60 wt % in the flavored sheet, and   the cellulose comprises at least one selected from a group consisting of methyl cellulose, ethyl cellulose, carboxymethyl cellulose, carboxyethyl cellulose, hydroxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropylmethyl cellulose, hydroxyethylmethyl cellulose, and agar.   
     
     
         3 . The woven fabric filter of  claim 1 , wherein
 the plasticizer is in an amount of 1 wt % to 20 wt % in the flavored sheet, and   the plasticizer comprises at least one selected from a group consisting of propylene glycol, polyethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, glycerin, and sorbitol.   
     
     
         4 . The woven fabric filter of  claim 1 , wherein the flavoring material is in an amount of 10 wt % to 50 wt % in the flavored sheet. 
     
     
         5 . The woven fabric filter of  claim 1 , wherein the flavored sheet has a thickness of 1 millimeter (mm) or less. 
     
     
         6 . The woven fabric filter of  claim 1 , wherein the flavored sheet has a tensile strength of 1.0 kilogram-force (kgf)/15 mm or greater. 
     
     
         7 . The woven fabric filter of  claim 1 , wherein the fiber has a diameter of 1 mm or less. 
     
     
         8 . A smoking article comprising:
 a filter portion comprising the woven fabric filter of  claim 1 .   
     
     
         9 . The smoking article of  claim 8 , wherein the woven fabric filter has a circumference of 14 mm to 25 mm and a length of 5 mm to 20 mm. 
     
     
         10 . The smoking article of  claim 8 , wherein the smoking article is a cigarette or an electronic cigarette and is in a form of a cigarette. 
     
     
         11 . The smoking article of  claim 8 , wherein the filter portion comprises:
 a first filter; and   a second filter comprising the woven fabric filter.   
     
     
         12 . The smoking article of  claim 8 , wherein the filter portion comprises:
 a first filter, a second filter comprising the woven fabric filter, and a third filter comprising a tube filter or a paper tube filter; or   a first filter, a second filter comprising a tube filter or a paper tube filter, and a third filter comprising the woven fabric filter.   
     
     
         13 . The smoking article of  claim 12 , wherein the first filter comprises a fibrous form, a filamentous form, or both, wherein the fibrous form and the filamentous form each comprise at least one of a polymer, paper, cellulose acetate, activated carbon, and carbon. 
     
     
         14 . The smoking article of  claim 11 , wherein the first filter comprises a fibrous form, a filamentous form, or both, wherein the fibrous form and the filamentous form each comprise at least one of a polymer, paper, cellulose acetate, activated carbon, and carbon.
