Abstract (en)
[origin: WO8102243A1] The object of the invention is to treat cigarette paper so as to improve fire safety, reduce offensiveness of the cigarette to the non-smoker, and for reducing the health hazard to the non-smoker. Cigarette paper is treated by one or the other of two alternative processes, The first alternative process is characterized by the step of coating between 40 and 100% of the surface area of the paper with an aqueous alkali metal silicate solution, the SiO<u2>u concentration of which range from between 12 and 16% for 40% coverage to between 7 and 15% for full coverage. The second alternative process is characterized by two sequential uniform coatings of an aqueous alkali metal silicate solution, the SiO<u2>u concentrations in each solution ranging from 1.7% to 6%.
Abstract (fr)
Le but est de traiter le papier a cigarette pour ameliorer la securite contre le feu, attenuer les desagrements de la cigarette a l'egard du non-fumeur et reduire les dangers que presente la cigarette pour la sante du non-fumeur. Le papier a cigarette est traite par l'un ou l'autre des deux procedes proposes a titre de variantes. Le premier procede se caracterise par le revetement entre 40% et 100% de la surface du papier avec une solution aqueuse d'un silicate de metal alcalin, dont la plage de concentration en SiO2 se situe entre 12 et 16% pour 40% de revetement et entre 7 et 15% pour un enrobage total. Le second procede se caracterise par deux enrobages uniformes sequentiels d'une solution aqueuse d'un silicate de metal alcalin, dont les concentrations SiO2 dans chaque solution se situent entre 1,7% et 6%.
