Two months ago I bought a tool chest in an attempt to tidy up my workshop.
To my horror many of the tools are going rusty, like this V Block for example:
The only surface affected is that in direct contact with the bottom of each drawer. It look like there is a layer of material which looks like baize (but is not) glued to the wood and the parts are actually stuck to this. So the question is what has caused this, and more importantly how can I prevent it ?

Moisture in the wood ??

You could line the drawers with VCI rust inhibitor paper.

Buy youreself a small dehumidier. this will take all the damp from the air in your room., This will stop any rust from accumilating.

I would suggest the baize has been fixed in place with PVA adhesive ( Polyvinyl acetate).

A tool chest that rusts tools is not fit for purpose! Return it and get a refund.

Could it be the type of wood? Some types of wood can cause corrosion, I'm sure this has been discussed on the forum.
I have a wooden toolmakers cabinet (Union?) bought some 40 years ago, corrosion has never been a problem even when my workshop was a cold and damp wooden shed.

A lovely piece of furniture but I don't think it was originally made for storing metal tools.. Buying second hand and not intended for a tool box, it is buyer beware and you cannot expect a refund.
Best option is to seal the drawers or line with a suitable material and coat the tools with an anti rust product. Lots on the market. Lanelin (from sheep wool) used to be what the old timers used. Now availavle in spray cans. Good on your hand also.

Those Clarke toolboxes are available new at very reasonable prices, is the OP's box new?
There's one on display in the window of my local branch of Machine Mart (can I say that?).

I have an identical tool chest (Machine Mart), which I bought to store my measuring equipment. It is kept in the house as my workshop has a damp problem in the winter. I have had no issues with rust, so perhaps it is the location of your chest rather than the chest itself.

+1 for desiccant type dehumidifiers, they also give out a little bit of warm air, every little helps when heating the workshop. I used to have a refrigerant type, which worked well but would freeze solid during winter. I collect the water and use it in the loco.

Bob Wild didn't say his tools rusted before they were in the chest, and they only rusted when in contact with the lining. This implies that the workshop is not damp and causing the rust.
These chests are available new, and so Bob may have bought a new one from Clarks. Michael's link shows that they are sold as tool chests.
So, if Bob bought it new, the first step should be to return it to Clarks as not fit for the purpose for which it was sold.
We are all practical types and try to find solutions to problems, but all too often this leads to us accepting unsatisfactory goods from suppliers.

|I too would suspect the cabinet was somewhat damp on purchase and that attack on the metal looks very much like what PVA does to metal - woodworkers will see similar if you use a bit of steel pin (even if Stainless Steel) to plug the spout in a flexibottle of PVA|

It is likely that the baize-like material on the bottom of the drawer is a spray-on coating of some description probably a plastic material either applied as one coat or as a dry flock onto a sprayed on adhesive. Would seem likely that the rusting is caused by an adverse reaction between the coating/adhesive and the tool face.
A few choices, as suggested above return as unfit for purpose, further line the drawers with VLC paper or non-slip drawer liner or scrape off the offending coating and apply a new liner. Leaving the old lining in place it may eventually leach through the new liner. The current lining material may eventually "dry" and the volatile/corrosive agent may go.
Seem unlikely to be the wood as this appears to be pine which is usually benign. Hopefully not the varnish either as this should have lost all the volatile agents by now.
Hope you get the problem sorted as it appears to be quite a useful toolmakers cabinet.

"Felt-lined drawers keep tools from sliding during transport and help prevent moisture damage to contents " or so the Machine Mart sellers blurb says,

First post here as a new member, I'm actually a woodworker (with aspirations of engineering so be gentle). This looks like it is coming from the glue rather than the wood but difficult to assess from afar! If the wood was not dry it would create a micro-climate within the drawer causing rust to start all over. If your workshop is damp in any way (excluding the summer months) I would avoid storing tools in a wooden cabinet as it will absorb moisture from the air over time, possibly exacerbating the problem. I would remove the baize and replace it with something impervious.
Happy to answer any wood related questions.

I agree with most of the above as possible reasons for the rust. The chest was most likely made abroad and shipped by sea and stored in unheated warehouse space and so has had every chance to get damp. The OPs workshop may be heated and drier so that the moisture is coming out of the wood and being trapped in the drawer spaces. Also, PVA may have been used to stick the "baise" down and this glue creates acetic acid as it dries (and may decompose releasing Formic acid? ) Perhaps best to locate a newly owned chest ( even an old one) empty in the space it will occupy and with the drawers out, for a time, and to use VLC paper liners at least for an initial period. All these problems should disappear over time?
