Embodiment 1

[0010] A method for producing cellulose acetate tow for cigarettes that selectively removes harmful substances in smoke, comprising a pulping process for producing cellulose acetate tow for cigarettes, adding cellulose acetate capable of eliminating harmful substances to the slurry in the pulping process pulp additives. The addition weight of pulping additive is 2% of slurry weight. The pulping additive is activated carbon.

[0011] The addition weight of pulping additive in this embodiment can also be 10%, 20% etc. of the slurry weight. Pulping additives can also be fluorspar, molecular sieve, montmorillonite, medical stone, bentonite, alginate, attapulgite, layered phosphate, nano silicon dioxide, nano molecular sieve, nano titanium dioxide, nano starch, nano three Any one or several kinds of alumina.

Embodiment 2

[0013] A method for producing cellulose acetate tow for cigarettes that selectively removes harmful substances in smoke, comprising a pulping process for producing cellulose acetate tow for cigarettes, adding cellulose acetate capable of eliminating harmful substances to the slurry in the pulping process pulp additives. The addition weight of pulping additive is 10% of slurry weight. The pulping additive is a mixture of activated carbon and nano silicon dioxide, the amount of activated carbon and nano silicon dioxide is the same or blended in a weight ratio of 10-1:1-10.

[0014] The addition weight of pulping additive in this embodiment can also be 1%, 20 etc. of the slurry weight. Pulping additives can also be activated carbon, fluorspar, molecular sieve, montmorillonite, medical stone, bentonite, alginate, attapulgite, layered phosphate, nano silicon dioxide, nano molecular sieve, nano titanium dioxide, nano starch, A mixture of any two or more substances in nano-alumina,...
