Cigarette Filter and Method of Its Manufacturing

Abstract

The invention relates to the cigarette filter containing the microfibres, which contains from 0.5 to 10% by weight of polymeric nanofibres, that are arranged among the microfibres. At manufacturing of cigarette filter containing the microfibres, the nanofibres or shreds of surface nanofibrous textile are brought to the surface of a configuration designated for production of the cigarette filter formed at least of 90% by weight of microfibres, and they are deposited onto the surface and/or into the volume of the configuration in a quantity from 0.5 to 10% b weight.

1 . The cigarette filter containing the microfibres wherein it contains from 0.5 to 10% by weight of polymeric nanofibres, which are arranged among the microfibres. 
   
   
       2 . The cigarette filter according to the  claim 1  wherein the nanofibres among the microfibres are arranged evenly within the whole volume of cigarette filter. 
   
   
       3 . The cigarette filter according to the  claim 1 , wherein the content of nanofibres in the cigarette filter lies within the range 0.5 to 3.0% by weight. 
   
   
       4 . The cigarette filter according to the  claim 1  wherein the nanofibres are arranged in the form of surface and/or linear textile configurations, which are positioned among microfibres, or among the configurations created by microfibres or configurations which contain the microfibres as the main component in the quantity at least of 90% by weight. 
   
   
       5 . The cigarette filter according to the  claim 4 , wherein the nanofibres and/or the textile configurations formed of nanofibres are positioned on surface of configurations created by the microfibres or containing the microfibres. 
   
   
       6 . The cigarette filter according to the  claim 4 , wherein the textile configurations created by nanofibres are the surface and/or linear textile configurations having the typical dimension up to 5 mm. 
   
   
       7 . The cigarette filter according to the  claim 6 , wherein the textile configurations formed of nanofibres are the shreds of surface nanofibrous textile having dimensions up to 5×5 mm. 
   
   
       8 . The cigarette filter according to the  claim 1  wherein the nanofibres or shreds of surface nanofibrous textile are applied onto the surface of a crepe paper containing the microfibres in the quantity of at least 90% by weight. 
   
   
       9 . The cigarette filter according to the  claim 1 , wherein the nanofibres or shreds of surface nanofibrous textile are applied onto the surface and/or inside the surface textile configuration formed of microfibres, out of which the cigarette filter is created. 
   
   
       10 . The cigarette filter according to the  claim 1  wherein the nanofibres or shreds are applied onto the surface and/or inside the linear textile configuration formed of microfibres, out of which the cigarette filter is created. 
   
   
       11 . The cigarette filter according to the  claim 10  wherein the linear textile configuration is the microfibrous cable. 
   
   
       12 . The cigarette filter according to the  claim 10  wherein the linear textile configuration is the microfibrous thread or the microfibrous yarn. 
   
   
       13 . The method of production of cigarette filter containing the microfibres wherein the nanofibres or shreds of surface nanofibrous textile are brought to the surface of a configuration designated for production of the cigarette filter created at least of 90% by weight of microfibres and they are deposited onto the surface and/or into the volume of the configuration in a quantity from 0.5 to 10% by weight. 
   
   
       14 . The method according to the  claim 13  wherein the quantity of nanofibres varies in the range from 0.5 to 3% by weight. 
   
   
       15 . The method according to the  claim 13  wherein the configuration designated for production of the cigarette filter is a crepe paper, to whose surface the nanofibres or shreds of surface nanofibrous textile are applied and which is after then rolled down into the shape of cylinder creating the cigarette filter. 
   
   
       16 . The method according to the  claim 13 , wherein the configuration designated for production of the cigarette filter is a surface textile configuration formed of microfibres, while the nanofibres or the shreds of surface nanofibrous textile are being deposited onto the surface and/or into the volume of the surface textile configuration, which is after then formed into the shape of cylinder creating the cigarette filter. 
   
   
       17 . The method according to the  claim 13 , wherein the configuration designated for production of the cigarette filter is the linear textile configuration formed of microfibres, while the nanofibres or shreds of surface nanofibrous textile are being deposited onto the surface and/or into the volume of the linear textile configuration.
