It takes acetic anhydride to do that.

Isn't Cellulose Acetate the stuff they use for cigarette filters?
Could be expensive if you're not a smoker though...

This thread should be of help.
The only other way is to use acetyl chloride, and trust me, you would do well to stick to the anhydride.

Film
Isn't camera film based on cellulose acetate ?
Just a thought.
From opening of NCIS New Orleans - It goes a BOOM ! BOOM ! BOOM ! MUHAHAHAHAHAHAHA !

Yes, that is true. It replaced cellulose nitrate (Celluloid) for this purpose.
Mylar (PET) is sometimes used.

Transparencies (those clear plastic sheets for overhead projectors) are made of cellulose acetate.

Can I hydrolyze cellulose acetate to cellulose and acetic acid?

OMG! Really!? We're in Tunisia trying to recycle old cigarettes There's a lot everywhere and I know someone wants to recycle the cotton which is
cellulose acetate! He collected a lot of cigarettes in the past 5 months and he asked me to help. if cellulose acetate can be hydrolyze using sodium
hydroxide or something we can make ethanol, acetic acid, acetone from cigarettes!

If you would like to produce acetic acid from cellulose acetate by hydrolysis I would recommend acid hydrolysis because
1. Using NaOH will not give you acetic acid, it will leave sodium acetate
2. Cellulose is degraded by aqueous NaOH
By using HCl for example you will end up with acetic acid in solution, with cellulose left behind as it is almost entirely insoluble in water. I'm not
sure exactly how you would efficiently make ethanol and acetone though.

I'm fairly sure the acid will hydrolyse the cellulose to glucose at least as fast as it hydrolysis cellulose acetate to cellulose and acetic acid.
It's true that cellulose is degraded by sodium hydroxide, but I think that reaction is typically slower.

YO I don't care what happens to cellulose! It's amazing I can make SODIUM FREAKING ACETATE! From cigarette filters!

Or I can hydrolyze cellulose acetate using calcium hydroxide to make calcium acetate! And then pyrolyse this to ACETONE are YOu SerIouS! ;D

You can certainly make sodium acetate that way.
Calcium acetate may be more difficult. The solubility of Ca(OH)2 is very low so the solutions are dilute and only react slowly.
It should work, but it will be slow.
Cleaning up the used cigarette neds is a good thing to do, but I find it hard to believe that it's worthwhile compared to adding NaOH to spoiled beer
or whatever.
Acid hydrolysis of the filters will give glucose which can be fermented to ethanol, and then to acetic acid.
